Can I restore my CM10.1 phone to factory ROM without using USB?
I have a Galaxy S2 i9100g with CM10.1 release.  Everything is peachy except that the USB port seems to be going -- most of the time I can't charge or connect to a PC.

I'd like to send it in for warranty repairs, but I figure I should put it back to factory before I do so.  Normally I'd find a "stock" image and flash it with Odin or something, but I wouldn't trust a firmware update to complete successfully over the wire with this wonky connection.

(Before you ask: this is definitely not a custom firmware problem; it won't even charge properly when turned off, which is before any custom ROM / bootloader even starts.)

Can I somehow flash back to factory via recovery?  If so, can I then re-flash back to CM10.1 (in the event I can't get it repaired for some reason), without using the USB connection?


问:
Errors when receiving iMessage group texts
Phone: Samsung Galaxy SIII

OS: Android Jelly Bean 4.1.2

I've tried talking to Samsung, AT&T, and reading forums looking for a good answer to this, and I seem to be the only person experiencing this exact problem.

When someone sends me a group message from iMessage on an iPhone, one of 3 things happens.

I receive the message from the original sender, no evidence of other people on the message, and receive a message from 'Anonymous' at the same time that says "Message not found."

I receive the message from the original sender twice, sometimes with the error message, sometimes not.

I only receive "Message not found" and the actual message never reaches me.

All I want is to see the group message from iMessage without an error or a duplication, and it would be nice to know it's a group message. Icing on the cake would be to actually reply all and even see who else it was sent to. I have not seen anyone else report this particular error. This has been an on-going problem, not a recent one, that I was only very recently able to diagnose. Today's advice has ranged from telling every one of my iOS friends to turn off Android messaging in iMessage, to deleting my phone number from the Apple Support page (which does not and never has had an iPhone attached to it), to resetting my device.

Even if the answer is This is a common issue because Samsung and Apple love to feud and piss off their customers, so they make it impossible for you to communicate with the enemy, I would love to hear that.

ES File Explorer suddenly not allowing connection?
I downloaded the ES File Explorer a while back to get access to my shared files, folders and my 2TB external drive. Everything worked fine until today.

I tried to access my external HDD but got an error back.

So my big question is: Why can I access my other folders but not my external HDD? As stated above everything worked fine until today...

I didn't change any permissions in Windows nor did I reinstall it.

My login works, because I can access my other HDD without any problems.

I did however install a secondary Graphics card. (Hardly think its the GPU :P)

Any Ideas, help would be much appreciated!

Thanks!

Update:

So today I backed up all my files on my 2TB disk that is not recognized by ES File Explorer. I then went into Windows Disk-management and Deleted the 2TB Volume. After that I created a "New Simple Volume". I then tried to connect to the device through ES File Explorer, but still got the error (see picture above). So it defenatly has nothing to do with the windows permissions.

I also re-installed ES File Explorer without success.

So I went and opened up the 2TB ext. HDD and connected it to one of my internal SATA Connections. I then deleted the HDD and created a ned simple Volume. Formated the disk and tried again. I still get the same error.

问:
How can I force-disable all dock detection/HDMI connectivity?
Context:

I have a RAZR MAXX XT912 with 4.1.2 (3.0.8-gbacb1cf). As soon as I wake it for any reason, it immediately acts as if it is connected via HDMI, despite the fact that no cable is connected.

Many people have this problem, and it is usually a result of a software issue or a shorted connection somewhere in the HDMI hardware/plug that results in a phone thinking it is docked.

For me, it occurs constantly (some people experience it intermittently)--as soon as I wake the phone from sleep/non-lit states, it immediately rotation-locks itself into widescreen and presents me with the docking choices menu.

Question:

Is there some way to permanently disable HDMI dock detection?

What I've tried:

I've tried the "HDMI Connection" setting; whenever I uncheck it, the phone goes back to normal. However, leaving it unchecked doesn't work: if I restart the phone with it unchecked, the phone acts as if it's docked when it starts again, and I have to go into settings, check the box again, and then uncheck it before the phone behaves. The phone also periodically "forgets" what that I've unchecked the setting (without a reboot), and I have to go check/uncheck it again.

I've tried clearing all application caches, to no avail.

I tried clearing the cache partition, to no avail.

Finally, I tried a factory reset, but the symptoms persisted.

I've fiddled around with a hand lens and a needle inside the HDMI connector, but couldn't observe any shorted pins and didn't manage to affect the symptoms at all.

How can I fix Google Speech Recotnition misbehaving: When it starts SR it freezes
Symptoms

If I launch Google Now it seems OK (I can scroll the list of Cards, etc.) but if  speak "google" it does not start voice recognition and it freezes (can't scroll the 'cards' down, etc.) or simply exits.
If I manually touch the mic, it sometimes works but usually it just exits without doing anything.
Google Chrome search (entering search term as text) works fine.
Google Speech Recognition freezes similarly in other apps when I choose the Mic from the keyboard (I.e., SR instead of keyboard for text entry)

Update:
This seems to be a general problem with Speech Recognition. SR isn't working in any other app I tried it with.

What I've tried:

Verified that Bluetooth is disabled.

Factory Reset

Cleared all Cache

Updated Google Now

Verified the Settings>Voice>Hotword ("google') detection is enabled.

cleared the App Data (not just the Cache) (for Google Search)

I'm going to try to figure out how to disable the offline Speech Recognition next.

Any other suggestions?

When I try to add a phone number to an hangout, the Hangouts app on Android tells me it doesn't know about that number and proposes to send an invitation text message.

Reversing the order of notifications in the notification bar of a given app
I have a Galaxy S1 (I9000) running SlimRom (Android 4.2.2).

The problem I have is the following:

Assume someone sends me 3 messages in whatsapp (this is case important to me, but the problem is in general): First he sends 'a', then 'b', then 'c'.

The way I see the notifications is, from top to button, is 'c','b','a'.

I realize this is caused by the stack like implementation of the notifications, but since I read top-down I would like to see it as 'a' at top, then 'b', and finally 'c' at the bottom.

I recall that with the latest CM10 I had (also Android 4.2.2) they actually fixed this problem, but I am happy with SlimRom and I don't want to change my Rom solely on the sake of this problem.

Is there anything I can do about it ?

The problem is that I don't have Windows, more explanation at the end.

More in detail:

V-Root is this soft: http://www.mgyun.com

If I well understood (Rooting/unlocking Android Nexus One with broken power button using Linux terminal tools) the rooting usually just install su command using some vulnerability in the Linux Kernel or in a daemon ... or any other similar vulnerability in the Android OS.

Reason

You may wonder why I'm not just grab a Windows pc from one of my friend and in my opinion there are a couple of reason for this:

Android (or better Android/Linux ) is using Linux kernel so in make sense to have some standard procedure to root on Linux too

Many of the Win. Root solution are shipped with some custom soft that we can not really trust ( for example V-Root, beside the fact that is in Chinese and few people non-chinese can understand it, how can I trust that it is not doing any malicious operation on my phone ? )

Most of the tutorial/forum thread are Windows oriented, so there are few and spare info related to Linux

So my question:

Is there a possibility to achieve the above on Linux? If not, is there any other method I can use on Linux?

Dialer problem with Galaxy Y after rooting
I recently rooted my Samsung Galaxy Y. I also used Link2SD to move some of the apps to the SD card partition to free up some space.

Since then I notice this weird behavior. When I go to Logs or Contacts and swipe on a number to place a call, the dialer will not get initiated. The screen will remain unchanged and the call will not get placed. And I will not be able to make calls for the next 5-10 mins.

Then when I try again, the call will get placed normally. But, when I disconnect the call after speaking, the dialer will try to dial the number which failed earlier and I need to disconnect it from dialing.

Also, If I had swiped on the contact more than once when the dialer didn't inititate, then after I disconnect, the dialer will try to place the call the exact same number of times I tried to swipe, in quick succession and I need to disconnect it during each time.

This happens often and is quite frustrating. Has anybody else faced this issue or can anyone suggest how I can solve this? I cannot unroot because I have less memory on the in built memory and I need link2sd to keep the apps installed.

Thanks in advance.

unable to charge Google Nexus I9250
I am unable to charge my phone most of the times.

When I connect my phone to the USB cable which is in turn connected to the computer or charger, most of the times (about 90 percent), I am unable to see the charging sign and battery discharges. However only in some special cases, in particular when I plug in the cable in the computer just after i press the power button, that too, selectively, the phone is able to charge.

Also : After this problem, phone only connects in AC charging mode and not in USB mode.

I brought this phone from another country so service centers here refuse to accept it. I just want to charge the phone as of now.

EDIT : Today I found a new problem. After charging it to around fifty percent with an old computer, I just plugged it into the wall charger. It did show just a sign of initialization but did not continue. When I switched on the phone, the battery was reduced to 10 percent

adb input swipe to unlock slide screen lock and open notifications
When I use the command adb input swipe, the slider slides all the way to the right, but does not 'click', so the screen does not unlock. I calculate the coordinates based on the (not visible) 'swipe area'. The same issue occurs when I try to drag the notifications open, I slide it all the way down, but it does not 'click' so notifications don't stay open.

I am using python 2.7 to call the adb functions, I think that may play a role too, but I've tried every form of os.system, subprocess.Popen, and subprocess.call I can think of.

Watch WWDC session videos on Android
Does anyone know how to watch Apple WWDC session videos on Android (not the keynote)? They are like Google I/O sessions videos but on Apple platforms.

On the Mac, one can watch it with Safari (not Chrome). And on iOS, Apple has built native apps for that. I didn't find WWDC apps in Play Store, neither does Apple allow watching the videos in Chrome.

For example, WWDC 2013, WWDC 2012.

Galaxy Note 2 screen problems
I'm experiencing a spot of trouble with my N7105 Samsung Galaxy Note 2 device. It boots up just fine, the screen works absolutely flawlessly for a few minutes, but then the problems start to appear. The screen progressively develops black bars, it stops refreshing in places, beginning from the bottom of the screen and moving upwards, and before too long the entire screen is covered in random noise.

Now, since this problem only manifests after the device has been turned on for some time, it makes sense to me if it were an overheating problem. I've pulled the phone apart and have thoroughly cleaned the cables and connectors to the motherboard with ethanol, but it doesn't seem to have improved the situation much.

If anyone has any kind of experience with this kind of problem, please report back.

Unable to install on USB storage or SD card?
I have a rooted Samsung Galaxy Y (GT-S5360L),  which I recently factory reset. Now I have a problem: whenever I try to install most apps it gives the error " Unable to install on USB storage or SD card."  I Googled and found 2 solutions: one to delete a cache file, and the other to unmount the sd card while installing. The cache file was sm2dltmp or something like that located in either /sdcard/.android_secure or /mnt/secure/asec. I used rooted terminal emulator to look in both and I did not find the file. I did however, find a bunch of .asec files for apps I used to have before I reset my phone. I moved those to a backup directory, but still installing apps gave me the same error. So far I have only been able to install apps using the second method, unmounting the sd card. All help would be greatly appreciated. </p>

问:
In Android 4, does disabling "Show notifications" have an effect on the process priority with regards to low memory?
Android 4 has a feature where you can disable notifications for an app by going to that app's properties and unchecking a checkbox. Both temporary and ongoing notifications will be hidden.

My question relates to low memory situations. If your device is low on memory, it will selectively kill processes to regain memory. Apps not in the foreground will go first. Apps that have a persistent notification have higher priority (though they, too, may be killed in extreme cases).

Many utility apps, like tasker, llama, Juice Defender, and others have an in-app ability to disable the ongoing notification icon. They all stress, however, that hiding the icon will cause their respective app to be more likely to be killed if there is low memory.

If I select to hide the notifications within the app properties, the app (presumably) doesn't know that it is being silenced.

If I hide the notifications via app properties, does the app therefore get pushed to a lower priority when memory is low? Or does the persistent notification simply get hidden, but is still running and giving the app the higher memory priority?

When i turn both on it becomes the 'right' time but i know that it really isn't since it says -04:00 but it still shows my time. For example, my time here would be say 12:00 A.M on my computer clock but then on my phone if i set it to eastern standard time it would show 11:00 P.M instead of 12:00 A.M . its hard to explain but then when i turn it all off and i change it manually to the right time it works perfectly... except for one thing.

I tried a few ways...at first I tried TitaniumBackup, but when I move my backup to the new one and check the integrity, titanium backup says that there are faults. When I try the restore, the app hangs at 0%.

Then I tried the adb backup with the Nexus Root Toolkit...but when I restore, the restore windows ever appears at the first user even though I'm logged in at the second user.

Then I thought about, I can do it manually..
I know that the main app data will be saved at /data/data/package and the specific user data will be saved at /data/user/0 or 10 etc /package. I tries to copy the files from one device to the other...but when I start the

Migrating data from a Galaxy S3 Mini to a normal Galaxy S3?
My sister has a Samsung Galaxy S3 Mini, but for whatever reason she threw her money away purchasing a regular Galaxy S3 yesterday, saying she prefer the bigger form factor. (I'm not gonna get into that.)

She asked me yesterday if there is any way to move her currently stored data in the S3 Mini to the regular S3 phone (both of which, I figure, are running the same 'Droid version). This basically encompasses contacts, messages, and app data (like notes and so on), but not necessarily the apps themselves.

I am a complete neophyte in Android stuff, since the only thing I've done in it is basically rooting an old Xperia X8 phone running 2.1 Éclair in order to have screenshot utilities work and to be able to delete the disgusting default home screen UI the phone has, and even most of that was done for me by someone else.

If this can't be done, I'll settle for being able to move the contacts from one phone to the other and screw everything else. ¬_¬

Making notifications easier to hear when listening to music
I would like to find some way to make it more likely for me to hear my notifications (mostly incoming SMS) while I'm playing music on my phone.

The phone does vibrate, but that is of little help if I'm not very close to it. And it does play the notification sound, but it easily gets lost among the music. It's very frustrating to miss a text message and answer it way too late even though you were right next to your phone.

Ideally, I'd want to make it so that the music's volume is cut for about a second of silence, then the notification sound would play, followed by another second of silence, and then the music would come back.

Actually that's the only solution I can think of, but I don't know everything. Surely, it's possible, since most media apps are able to cut their volume to play the ringtone if a call comes during playback. But does there exist a solution?

Tethering a "reversed tethered" data from a pc?
I have a Samsung Galaxy S 4G mini (GT-I8190) and I know I have the hotspot feature built-in which transforms my phone into a modem. I have used it plenty of times to tether my phone to other devices (tablet, laptop, etc).

I have discovered recently that it is possible to do a Reverse Tethering and plug the phone to the computer via the USB and get data running on the phone from the PC.

Now, I am interested to combine the two - in order to transform my phone into a real router. I tried to enable the hotspot while getting data from the PC. The phone has access to the internet. And my tablet was able to join the hotspot Wi-Fi network - but it has no network access.

Can anyone shed some light on:

How USB-tunneling works as far as transmitting the data from the
PC? All I know is that it forwards data from a certain port on the
PC. I tried to find an "open code source" for the USB Tunneling app but could not. I wanted to have a look on how they manage the data.

How does the built-in hotspot feature functions? Does it only forwards the Mobile Data to the Wi-Fi? Can anyone share/direct me where to find an open code source for a  tethering app? (the built-in hotspot works perfectly - but all downloaded tethering apps fail to run on my I8190).

I tried to find a tutorial, app, or anything that can explain on how to Wi-Fi tether a Reversed Tethered data without great success. Can anyone help?

HTC desire x issues after update to Android 4.1 Sense 4+
Ever since I installed the update to 4.1 I've been having major issues with my desire x.

The keyboard disappears frequently while typing, sometimes I can't get it back without closing the app and restarting.

When I exit a lot of apps, but most notably any of the browsers (I use Firefox and Chrome but have also tried the standard browser) the home screen shows the loading symbol for several seconds and I have to wait before I can do anything.

Lots of apps close without warning.

Debugging Galaxy S2 Bluetooth problem: Bluetooth disconnects, Bluetooth status never fully turns on, Only reboot resolves this
I know many have problems with Bluetooth and certain car kits. I specifically have a VW. In any case, my Galaxy disconnects from not only my car, but also from my Philips in home audio system. In both cases, the disconnect is the same. What happens in both cases is the Bluetooth pair is lost. If I try to turn off and then on the Bluetooth (on the phone) to reset the pair the Bluetooth light never fully turns on. It stays a dim green. To get it to work I have to restart the phone.

I wrote a script to collect the Bluetooth logs, and programmed it to start logging whenever Buetooth is connected. See link below for the3 log. notice that around 7:56 the probem occurred. I was in a call on my galaxy s2 connected to my vw tiguan, and the hands free audio stopped. I was able to pick up the phone and switch from hands free to the speaker (on the phone) to resume the call.

Around 8:19, I think, I turned off the Bluetooth on the phone, and then tried to to turn on it again. But,it did not fully turn on. The green Bluetooth light is dim rather then bright. The only way I can restart the Bluetooth is to reboot the phone.

There are exceptions thrown that I am going to look at.

Have any thoughts?

Galaxy s2 is recognised by computer but doesn't charge
This is an odd one but today I noticed by S2 wasn't charging while plugged in. I tried connecting it to the computer and it came up as a media device as normal but still didn't charge, the battery percentage went down until it was 0% and the phone shut off.

Is there any way I can fix this myself?


问:
Switching to Android, how do I handle music?
My wife and I are planning on switching from apple phones to the Note III when it comes out later in the month. I was preparing to switch my music collection from itunes based to google play by uploading and organizing everything to the google play web app. However, I ran into a couple of issues.

I have a computer that plays background music during the day, regardless of if we are home or not. Up to now I have been playing it through itunes, however since I have been pulling the google play web app during day, I have noticed that if I play music from work, that I come home and the music has stopped playing because you can only stream music from one device at one. I would like to have this music playing at all times.

I assume, since my wife and I share the same music collection that we will both sign in to google play using the same google ID. However, if only one device can stream at a time, what happens when I am listening at work and she is wanting to listen at work. Will it kill one of the streams?

Has anyone else run into this? Is there another way to manager music on the Android platform?

Snapchat receives blank chats
Since signing up for Snapchat about a month ago, I have regularly received Snapchats that are simply black screens (and obviously confirmed that the sender did not send a blank screen) about 1 out of every 4 messages.

I have the LG Spectrum 2, running Android 4.1.2 (JB) and just did a factory reset in an unsuccessful attempt to fix Snapchat. I have tried using an old version of Snapchat (v2.something) which received less blanks, but still some, as well as the new Beta version which received just as many as the most recent version. I even tried signing up for a new account and deleting the old one - this worked for about two days and then the same problem started again with the new account.

问:
google contacts sync
I have 2 Samsung Android phones and both are synced with 1 gmail account. now the issue i am facing is:

The number of contacts restored on both the phones is different. ie. for example I have total 500 contacts stored on gmail one of my phone is showing 490 contacts and the other is showing 495 contacts, where as in total I have 500 contacts.

Sometimes when I add contact to one of my phones it automatically adds the contact on phone memory & google contacts on the other phone instead of google contacts only. I want to store to google contacts only and not phone memory as it slows down my phone.

What could be wrong here, and how can I fix it?

Can't boot because of deleted com.android.launcher2
Stupid me deleted the com.android.launcher2 apk file (located in system/app) thinking that my tablet will boot with another launcher I installed and now it doesn't boot up (gets stuck in loading screen).

Now, the tablet's chinese, so I haven't installed a custom bootloader.

I can only get to recovery mode.

I have a backup of everything, (made with an app) on my external SD card, so I did a fac reset (and a cache one), just in case. It did't work.

So now:

I need to manually copy a file in system/app via system recovery, without a Custom Bootloader.

I tried making a custom update.zip, with launcher2.apk in it by I get an error "Installation aborted" right after it starts authenticating it.

Is it possible to copy that file without having a custom bootloader, or is there another way to do this (adb commands).

PLEASE help me, I'm really frustrated right now.

问:
Lost Google account information after sync to local Outlook 2003
Normal newbie disclaimer... I've looked and I can't find an answer, so apologies if a duplicate.

After quite a bit of trial-and-error, I've managed to sync all my contacts on my local Outlook 2003 through my new Samsung Galaxy S4Mini (i9195) using MyPhoneExplorer.  There was a lot of swearing as it firstly made them phone contact, but eventually I managed to make them Google contacts.

Before I did this, all my messages and emails were showing my profile picture and Google account details with those messages/emails/etc on both of my Android devices (my phone which is only linked to my Google profile, and my tablet which is linked to both my and my partners profiles).  So, for instance, instead of seeing the letter "T" against the "conversation", I was seeing the profile image.

Under the contacts on my devices there is a "Tom" contact under the "ME" section, and I've attempted to update that with my gmail address, but that doesn't appear to have linked it.  Nor am I seeing my details within the contacts via the website.

I do not have a Google+ account, and I do not want a Google+ account... I have Facebook, and to be honest, I'm on the verge of deleting that.  (I do NOT have Facebook syncing with the phone either).

Gmail through a browser is showing my profile picture, however, that image is NOT appearing if I look at the google account settings... which I'm sure it used to.

Is this just "get people to use Google+" by Google, or am I missing something really easy... or something that is really not obvious in the slightest.

Update:

Apologies @dotVezz for not giving you the information you needed upfront.

I have a single Google account, with a gmail.com email address.  When I look at the profile for that (by going into Gmail account through the web, clicking my email address in top right and choosing "Account") I am not seeing the profile image, which I'm sure I used to.

However, in Gmail settings I am seeing the profile phote.

I have two devices, a Galaxy S4 Mini (i9195) running 4.2.2 and an old Galaxy Tab 10.1 running 4.0.4.

What's happening (and is wrong):

On the S4 Mini, under the "ME" section in Contacts, I'm seeing a single entry called "Tom", which has no details at all... I have added my gmail.com address to this to try and fix this issue.  I do not appear to be able to delete this "contact".

On the Tab 10.1, under the "ME section in Contacts it is asking me to "Set up my profile"... bare in mind this device is used by two people with two accounts.

When viewing my messages or email via the Gmail app, I am not seeing my profile image against the messages I have sent.  In the coloured box to the left of the conversation it would show my profile picture, but now it shows my initial "T".

This is happening on both devices

What should be happening:

My profile image should be appearing next to my messages/emails/etc, instead of just my initial.

Update

Now I've discovered that it's Home+Power to screen shot (and not VolumeDown+Power as I've read in multiple places) here are screen shots from the Gmail and Messages apps on the phone, with the areas in red boxes that should have been linked to my profile, and therefore should (and were) showing my profile photo!


问:
Message app doesn't merge messages sent/received from same number but different format
My network provider usually sends incoming SMSs with number format like +84123456 (equivalent to 0123456), but sometimes 0123456, and I usually save in my contact, and send SMS to 0123456.

In my old Android phones running 2.3 and 3.0, the Message app can regconize and merge them into 1 thread. But with my new Android running on 4.0.1, they are seperated into 2 threads, 1 for +84123456, and 1 for 0123456.

Can I make it merge them?

How can I control the media volume while using the camera?
I just upgraded to a Nexus 4 and have discovered the behaviour of the volume controls has been overridden within the camera app.  The volume up button has been remapped to snap the camera shutter.  As I often listen to music on my phone, I find this a great inconvenience.

Onenote not as convenient as Google Keep. Solutions to integrate?
I am a heavy onenote user on the PC, but I find there is a 1-3 second delay on my phone between tapping new note and actually being able to type. As I use notes on my phone primarily for quickly capturing information and reliably finding it later, this delay is too long. Google Keep does this far better, but I hate to have my notes in two places.

I would be very happy to be able to find a way to add simple (plain text files would be ok but not perfect) notes very quickly and have them somehow synced to the unfiled notes section of my OneNote, which is on Skydrive.

OS services and Android OS using data
I have a question following up Locking applications to wifi only data connections:

I followed the guide given in its answer and notice some applications (like Android OS) don't have the option to be turned off. Is there any solution for this? At Data Usage the "app" called Android OS is using data but I don't wanna use data unless I'm on WiFi for that process.

What I'm trying to achieve (on the Xperia Z) is that on WiFi all apps have full access to the internet. On mobile data I only want Whatsapp and Gmail to be syncronised.

I disabled everything that uses data exept the mentioned apps above and I can't get

I also have My Data Manager installed. It says OS services is using 111kb so far, and it's going up. Another process called Android System has used 78kb.

In short again the question: some applications (like Android OS) don't have the option to be turned off in Data Usage. Is there a way to stop this process (and other processes) to use data unless I'm on WiFi?

One S reboots with new CM 3.4 Kernel
This is something that's been bugging me ever since the 3.4 kernel was released:

Problem:
I am getting intermittent reboots when using any ROM which is based on the 3.4 kernel. It happens totally at random, but only when I'm actually using the phone - never when it's locked, or in my pocket.

Here are my last_kmsg logs, but this is where it gets really weird - it reboots twice. Every time. Once I get the initial reboot, it reboots to the HTC screen, then immediately reboots again. So I'm not sure the last_kmsg will even be that accurate.

Things I've Tried

Returning to stock RUU/upgrading/reflashing

Not restoring apps

Switching off Wifi

Undervolting/Overvolting

Different CPU Governors/Clock Speeds

Many different ROMS

CM10.2 Kernel & also Bubba Kernel

LG L5 restarts every minute
I don't know what I've done to my LG L5, but now it's just restarting and restarting.
I've rooted my phone using adb and installed ClockworkMod recovery, but now it just restarts every time it loads into phone or into ClockworkMod.

I really don't know what to do. Even if I get new ROM onto sdcard and try to flash my phone, it could randomly (in 1 min) shutdown, and I guess then I will brick my phone. So what should I do? I've tried to wipe cache/data/dalvik cache.

At first I could get to my home screen and even work for a while, but now I can't even go to my home screen. It freezes on the boot logo and restarts after 1 minute. Even in ClowkworkMod recovery. Works one minute and restarts.

Is there something that could help me?

Ok, so for now I've updated to cyanogenmod, thought it'll help, but no. It just keeps restarting, but now it goes to home screen again. So what to do? How can I update kernel or whatever I need to do?

Tasker stops executing tasks after a certain period
For some reason I'm having problem with using Tasker on my Huawei Ascend P6:

Android: 4.2.2

My phone is running the official ROM (but rooted!)

Run Foreground is checked under Menu / Prefs / Monitor /Run Foreground

I had set up a simple profile that would enable wifi, enable data, turn on auto sync, .. every X minutes. After trying this out it became clear that after a certain period Tasker would simply stop running this profile.
For testing purposes I have:

Double checked that there are no task killers installed

Created a
profile of type "Time" that will Vibrate for 1 second from 07:00
every 2m Till 22:30

Enabled the "log to sdcard" functionality

After monitoring the log I have seen that there are no error but Tasker simply stops running the tasks after a certain period.

PS: I must say that I'm having the same issue with all other battery saving applications too (Juice Defender, GreenPower, Deep Sleep Battery Saver). They work perfectly until after a certain time they stop firing their events to enable the connection in the background.

Edit1: Below you can find a partial dump of the log that illustrates that it does actually run but that after a while it take way longer than configured.
As you can see at first it runs fine every 2 minutes while at some point it only runs every 10 minutes...

Galaxy S3 display issue
I have a Galaxy S3 International Version, without any modification whatsoever.

However, of late, I have begun experiencing problems with my screen / display.

Graphics display issue

The problem goes as follows: When I pull down the notification menu on the home screen slowly, I see that the the part of the screen that is visible is being displayed in poor quality. If i continue dragging, towards the last one third of the screen I begin to see banding similar to gradient banding.

Another issue, that goes in conjunction with the one above, is that the display seems to be grainy. Say, I press the apps button and see the icons of the apps I have installed. On top, where the option exists to see 'Widgets' or 'Apps' I see a grainy band run across those buttons. Grains can also be seen when browsing the internet or scrolling a list and so on.

I am unsure as to how to solve these problems. There are a few more 'problems' that I would like to discuss, probably on a different thread.

But for now, this is the one I have.

Can someone please tell me how to solve this?

Read access to /data/data/com.android.chrome/app_chrome/profile on a Nexus 10
How's this for a catch 22 - I would like to make a copy of the full folder structure starting at the path above. I have explored:

Finding ways to move the app onto the internet data storage (SD card equivalent), before realising that it would likely still leave the app data in the protected /data directory

Looking for ways to root the device, without wiping the storage, as I have read is possible for a few other mobile devices (Nexus 7 for one)

"Temporary rooting" the device - This looks to be most promising, but I cannot find how to do this for the Nexus 10

In my desperation, have also tried to export the Chrome for Android history (least preferable solution), but:

Chrome for Android provides no way of saving chrome://history

The Google based sync is missing many pages, even whole days of pages, when viewing in Portable Chrome on the desktop

The press-and-hold clicking of individual links on chrome://history page, would take too long.

chrome:history doesn't display the full URL's, so the screenshots (Power + Volume down, concurrently) I took are only semi-useful

Then there is the open tabs:

chrome:sessions, chrome:tasks present a "Web page not found" error, which I presume means that they are not available on the Android version.

Does anyone have something else for me to try??

EDIT:

After Dan Hulme's pointing out that there is already a workaround to this, I would like to change this question to ask if there is any way to mount the back file adb backup produces, instead of having to recover it to a like device, in order to work with the files contained with the archive.

Samsung stock email application won't show "sent" email on phone (using gmail account)
I use a Samsung Galaxy S III and I use the stock Samsung email application and widget (which also comes stock on the Samsung Galaxy Tab 2).

I have four gmail accounts linked to my phone and I have all four gmail accounts configured for use with my stock Samsung email app (this is different than the gmail app available on the Play store).

IMAP is enabled in my Google accounts and all settings match those recommended by Google.

However, when I send an email from my phone the message doesn't appear in the sent folder, in my phone.  Oddly enough, the message does appear in the sent folder on my PC when viewing gmail in Chrome.

I believe that this error is related to Google's 2-step verification security settings.  I remember having this problem about six months ago and that was about the last time I had 2-step security active.  I don't remember how I fixed the problem, but it hasn't been an issue for a while.  But since that was about the same time I tried (and then gave up on) 2-step verification, I'm guessing that this is the issue.

I recently enabled 2-step verification, then I had the problem with my email, then I turned off 2-step verification, and then the problem went away.

I am well familiar with application-specific passwords and I have set them up (properly, to the best of my knowledge).  I also have Google's Authenticator app, and have used that when required.

I believe there is a bug in Samsung's email app that prevents outgoing mail from being saved in the sent folder when 2-step verification is active.

However, if anyone knows for sure what causes this, and whether or not there is a fix for it, I would greatly appreciate any help.

This is a list of Samsung S4 stock ROMs, but I am in the SPR or XAS zones? What does that even mean?

Is there a shortcut to backing the entire phone up and running the ROM? Is there a way I can boot into the room without flashing the phone, just to update the PRL? Is there an easy macro for all this stuff, or can it be simply done with an Cyanogenmod hack?

Currently, my Sprint phone is on PRL version 1.

What would cause a sudden spike in the battery charge level?
Today I spotted something this on the battery chart :

graph of battery history showing a massive spike (click for larger variant)

What is the reason of such erection ? Hardware problem ? Or maybe a bug ? Should I report it or is it a common problem with battery charts ?

PS: It was spotted in Nexus 7 (2013)

How can I decode a mobile encoded file?
I am using filelock software in my Android phone. You can encode (encrypt) any file in this software by a password. I forgot my password and without password I cant decode my file. Is there any solution that I can decode my files without knowing the password?</p>

Restoring stock Rom to HTC desire S
OK, I know there's stuff out there on this - but tbh I can't understand it.

I have a UK HTC Desire S on T-mobile. I used the official HTC download to upgrade to ICS last year (it was not OTA but on their website). However, when I came to unlock the phone recently (to allow my daughter to use it on another network) I cannot get it to prompt me for the unlock code.

I've performed a "factory reset" but that didn't help, and the best advice I can find online seems to indicate I should  restore the original OS. But I've not the faintest idea how to do this.

I'm not sure what other info to give - it is currently running 4.0.4 and Sense 3.6.

IF there's a dummies guide to this somewhere, I'm happy to be pointed - but I can't find it.

Chrome for Android: How to see network console information?
Is there any way to see networking information on mobile Chrome, ala the networking tab on fully fledged desktop Chrome, on the device itself? I'm attempting to try some remote debugging for a user but I can't really ask them to install the required software to test on a desktop. I need to see if any scripts / etc are failing to load.

Am I out of luck?

Wifi passwords were not restored on a new device
I got a new galaxy nexus phone running 4.2.2 and I noticed my WiFi passwords were not restored to this device.

I skipped the account login upon first start, but added it later on. Am I missing something? I'm pretty sure my passwords were automatically synced when I got a nexus 7 tablet last year.

Many thanks for helping with this.

Unfortunately, Software Update has stopped
I have Android 4.1.2 installed on my phone, which is not rooted. It's stock Android (I'm not sure if 100.00% stock though). This is the first Software Update notification that I have ever received.

Whenever I click it, I get the "Unfortunately, Software Update has stopped" message and the app closes. I tried opening it from Settings, but the same behavior.

How do I apply the update, if it's actually available? Or if that's not possible, how do I remove this notification? Is the phone maker/vendor responsible for this error? This is my first Android phone. Any help please?

Google+ id from Google+ App
I would like to get my id profile or my profile URL from the official Google+ app, in order to copy it to clipboard.

id  : {21-digit-number}

url : https://plus.google.com/u/0/{21-digit-number}

I would be also interested if there was a way to get it, from any official Google application on Android, different from a browser of course.

Google Play Music freezes the touch screen
I'm running a Samsung Galaxy S4 Mini.

I'm having intermittent issue with the touch screen freezing and no longer responding to any touches.

The power button works, as does the home key. The volume buttons do not appear to work. Once it's locked I can't unlock.

This appears to happen when I'm trying to use Google Play Music, but not every time. I'm only about 75% sure that the incidence of freezing is tied to the use of Play Music.

Any suggestions?

Recieved an SMS that deleted all my SMS
A weird thing happened to me today. I received an SMS and upon opening it from the notification bar on top, my SMS are all gone. I didn't even get to read the message. I have my SMS backed-up from a week ago so it's not much of an issue. But then how can this possibly happen? I am using GoSMS and CyanogenMod 7.2 btw. Any thoughts on what could've caused this?

Update
Okay now 5 days later, all my contacts have disappeared on it's own. I wasn't doing anything at all. I just notice my contacts are all gone. I did re-sync from Google and they're all back but what could possibly cause that?
