[Samsung Epic 4G Touch] Mattix724:
Now that we have the latest official release for the new TouchWiz GB27 4.1.2, I figured I would update this thread for those that have downloaded the update from FL24 to GB27 via Kies.

This guide was written for Sprint devices however the procedure is the same for Boost and Virgin variants of the Galaxy S2 Epic 4G Touch. The only difference is the kernel you flash after rooting.

You WILL need to use a PC in order to gain root access

DISCLAIMER

DO NOT USE AGAT RECOVERY TO FLASH ANY AOSP ROM. THERE HAVE BEEN CASES OF HARD BRICKS.

I WILL NOT TAKE RESPONSIBILITY FOR ANYTHING THAT YOU CHOOSE TO DO WITH YOUR DEVICE. THESE METHODS HAVE BEEN TESTED AND ARE PROVEN TO WORK. FAILURE TO FOLLOW DIRECTIONS MAY GIVE YOU UNEXPECTED RESULTS.

YOU HAVE BEEN WARNED.

How to root with SuperSU

You will need...

Odin3_v3.04

Source built Jelly Bean kernel

SuperSU-v0.97

Stock GB27 kernel zip - optional

SuperSU from the Play Store

1. Using a Windows XP or greater based computer, download and extract Odin to a directory which you are comfortable using. You can extract to your desktop if you want. I personally use my documents folder.

2. Power off then press and hold volume down and power to enter download mode, plug in your USB cable after opening Odin. Click on PDA to select and flash the source built kernel.

3. Download this file and reboot to recovery by pressing and holding volume up and power then flash SuperSU-v0.97.zip

4. After flashing the SuperSU zip, flash the GB27 stock kernel and reboot. This is now optional, the source built kernel works perfectly and can be used as a DD.

5. Download SuperSU from the Play Store.

6. Open the SuperSU app and update the binary.

This method WILL trigger the yellow triangle and increase your flash counter by 1 count.

Do you have an ugly yellow triangle after performing one of the first two methods? Do you want to get rid of that and reset your flash counter back to 0?

Chainfire has an app for that!
