Stuck on bootup screen from TWRP I am following this guide to root my Samsung Galaxy Core Prime SM-G360T1(MetroPCS) using TWRP.

What did I wrong:


I went into TWRP recovery
I pressed on "Reboot"
I pressed on "Power Off"
A pop up came up saying "Your device is not rooted, would you like to download SuperSu now?"
I pressed yes


Phone restarts and now is stuck on metropcs bootup screen and the interesting thing is its vibrating in a pattern... 2 vibrates then 1 after a second later and does that again in 3 seconds.

I did not put SusperSu into the internal memory so im pretty sure thats why its like "Wtf bro, where is SusperSu?"

So how do i get out of this? Help please!!!
Getting out of a bootloop

What you want to do is to restore a working system partition. 

You have two options available.

Option 1: Flashing a Custom ROM

Your first option is to download a custom ROM on the XDA-developers forum.
Make sure that the rom you've downloaded is for your specific model!
Mount your SDcard and copy your ROM to the device OR use adb and a command prompt to push the file to your SDcard 

adb push rom.zip /sdcard


If you have copied the ROM onto your device, go into the Wipe section and wipe the following partitions:


/system
/cache
/dalvik cache  


When you are done with wiping, choose Install and select your custom ROM. When done flashing, reboot your device without confirming the root dialogue. ;)

Then you should be good to go with a working system and a pre-rooted ROM.



Option 2: Installing a stock firmware.

Your second option is to flash a stock ROM (samsung).
Wipe the following partitions (should be automatically wiped when flashing with Odin but it won't hurt):


/system
/cache
/dalvik cache  


You can download the STOCK ROM from sammobile and follow these instructions (which can also be found on the sammobile download page)

Extract (unzip) the firmware file
Download Odin v3.11.1
Extract Odin ZIP file
Open Odin v3.11.1
Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
Connect phone and wait until you get a blue sign in Odin
Add the firmware file to AP / PDA
Make sure re-partition is NOT ticked
Click the start button, sit back and wait few minutes


After this procedure your device will be stock again.



So which method to use? I would go for the first option because:


You will be running a rooted custom rom
You don't have to reflash a custom recovery. 
It should be done quicker
