Go back to previous custom rom - adb issue I decided to try a custom ROM from here.

I downloaded Exodus ROM to my computer, and via ADB transmitted it to the sdcard/0/ folder. I then rebooted and flashed this custom ROM. Everything went well but I don't like this version, partly because it seems old.

The problem is that I don't know how to go back to the previous ROM(Jellybean).

I made a backup of Jellybean to a folder of clockwordmod, but when I flashed the Exodus ROM the Jellybean ROM was not there. 

So, what to do? I have it on my computer, but the problem is how to put it back to the phone. The problems are:


The ADB connection is not working via USB cable any longer.
I could download an ADB app from Play Store that uses Wi-fi, but the Play Store is missing in the phone. 


How could I possibly solve this issue?

Very grateful for answers.

Edit: I succeeded to downloading it to my phone, that is the zipfile that holds the OS jellybean. But at the bootmenu where I select the zipfile it starts but soon fails (installation aborted).

finding update package
opening update package
installing update

And then the droid is laying down with a read exlamation above. 


The zipfiles contents look like this

It is because Exodus doesn't come with Google Apps (aka gapps). You'll have to flash them explicitly. You may try these links to download Gapps:


AndroidFileHost
PA-Google Apps Plus(All ROM's) at XDA  


Caution: Always flash gapps package meant for your ROM only. E.g. Do not flash gapps for 5.1.1 over a 5.0.2 ROM, or the vice-versa. You'll end up with bootloops, device stuck at boot logo, and what not! 


  The ADB connection is not working via USB cable any longer.


Since you've already mentioned that the backup of Jellybean ROM is on the PC as well, you may transfer it to your Android device without using ADB at all.


Connect your phone via MTP into your PC and transfer the files; or,
As I mentioned in the comments, you can host an FTP server on PC (see this answer for know-how) and access it over wifi/hotspot/USB-tethering. 

Thereafter, you can use a browser like Firefox(apk available) to access the backup files and can download into Android.

Alternatively, you can host a server (locally; see this answer for know-how) on your Android and do the transfer from PC. But that would be too much to detail here (unless asked).

Once you've transferred files from PC into Android (in the folder clockworkmod):


Boot into Clockworkmod recovery;
Find some backup/restore option and select the backup file you transferred. It's best to clear (before restoring the backup) Data, System, Cache, Dalvik/ART cache to avoid any issue.
Reboot the device.


Done!
