As promised Samsung had updated the Galaxy S3 devices across the world with Android 4.1.2 Jelly Bean firmware. However, if you had a rooted ICS device previously, your device must now be unrooted with the stock Jelly Bean firmware running on it. The method you used to root your Verizon Galaxy S3 on Ice Cream Sandwich won’t work anymore. You now need to unlock the bootloader and perform a few more steps to get your Verizon Galaxy S3 rooted. We will guide you through the process so you can do it easily and comment below if you face any issues.
Though you don’t need to wipe data before you root your device, we recommend you to backup data on your phone using our backup guide because if you are stuck at the Samsung boot screen, you may have to wipe data from the recovery mode to get it past that screen.
Please note that the warranty of your device will be void after you root it. You can however gain it by flashing an OTA update that will unroot your device. Hack My Android is not responsible for any damage that your device might face with this tutorial, though it is very less likely that you will land in such situation.
- Download Device Drivers
- Download Odin v3.07
- Depending upon what you need, download any one of the below:
If you want only root, download SuperSU zip file.
If you want only to unlock your bootloader without root, download this zip file.
For both bootloader unlock and root, download this zip file.
- Place the downloaded zip file to your device’s SD card.
- Download VRALEC Bootchain (You need this bootchain because this is the only firmware which can be rooted as of now, you will use Odin to flash this)
- Download correct bootchain depending on your firmware:
For VRBLK3 (Jelly Bean 4.1.1) | VRBMB1 (Jelly Bean 4.1.2)
- Download CMW Touch Recovery 188.8.131.52 | TWRP Recovery 184.108.40.206 (download any one of your choice)
Flash VRALEC Bootchain
- Turn off your phone.
- Boot it into download mode. To do this, press the Volume Down and Home button togther and without releasing them press the power button.
- When you see the disclaimer, press the volume up button and power button to accept the disclaimer.
- Open Odin on your PC and connect your phone to the PC via USB Cable.
- If the ID:Com section in Odin turns yellow, you can proceed or you need to check your device drivers. I recommend disabling the anti virus program too.
- Click on PDA and select the VRALEC Bootchain file.
- Make sure only Auto Reboot and F.Reset time are checked in Odin.
- Click on Start and the file will be flashed on your phone.
- Boot your phone into download mode once again.
- Connect it to Odin.
- Uncheck Auto reboot in Odin
- Select the recovery file by clicking on PDA in Odin.
- Click on Start to flash recovery to your phone.
- Once it is flashed, disconnect your phone from PC and remove the battery.
- Re-insert the battery and boot it into recovery mode. To do this, press and hold Volume Up and Home button. Without leaving them, press and hold the power button unless the phone vibrates. Once the phone vibrates leave the power button alone and hold the other two buttons until you see recovery mode.
Root + Bootloader Unlock
- Make sure your phone is in recovery mode.
- Go to “Install zip from SD card”>”Choose zip from SD card” and select the zip file you downloads section above. (In the third point).
- Go back and select “Reboot system now”. You will be asked if you want to “Disable recovery flash”. Select YES.
Restore Original Bootchain
You may or may not do this but this will not affect your device anyway. You can flash your original bootchain back to the device if you have rooted it successfully. The procedure is same as that of flashing the VRALEC bootchain file using Odin.
