Hi guys! I believe most of you obtained root via this method by Jiangyi: [TUTORIAL] Root access for ICS on I9100G which requires a temporary CWM. Quite a few users face problems because in temporary CWM, internal storage is swapped with external storage, i.e. sdcard=internal storage, internal sdcard=external storage. It may be confusing for newbies, especially on their first attempt on rooting. Therefore, I decided to release an easier method, where you can flash the zip files directly via stock 3e recovery!

Requirements:
- Running a stock ICS/JB ROM
- External sdcard


Features:
- SuperSU v0.99 by Chainfire
- Busybox v1.20.2 by Stericson
- No yellow traingle
- No increase in binary counter


Instructions (Root):
1. Download SU-BB-Installer.zip from here: http://www.androidfilehost.com/?fid=9390233485161005747
2. Place it in your external sdcard.
3. Power off your device COMPLETELY.
4. Boot into recovery mode by pressing Volume up + Home + Power buttons simultaneously.
5. Navigate to "apply update from external storage" using the volume buttons.
6. Select it by pressing the Power button.
7. Select SU-BB-Installer.zip.
8. Wait for it to finish and navigate up (select "../").
9. Select "reboot system now".
10. Congratulations, you now have root and busybox!

Optional: (For ICS only)
To obtain CWM recovery in order to start flashing ROMs or mods, read on:
1. Download kTool from Play Store: https://play.google.com/store/apps/d...droiddev.ktool
2. For ICS: Download the CWM recovery kernel by codeworkx from here: [KERNEL][GT-I9100G] ClockworkMod Recovery 6.0.1.2
3. Extract the .tar file and you will get a file named zImage.
4. Place the zImage in the root of your internal storage.
5. Launch kTool and select "Flash kernel from /sdcard/zImage".
6. Reboot and profit! If you boot into recovery by Volume Up + Home + Power buttons, you will now see CWM recovery.


Optional: (For JB only)
To obtain CWM recovery in order to start flashing ROMs or mods, read on:
1. Download one of the stock recovery flashable zips of Blazing Safe Kernel from here: http://forum.xda-developers.com/show....php?t=2293576
2. Place it in your external sdcard.
3. Power off your device COMPLETELY.
4. Boot into recovery mode by pressing Volume up + Home + Power buttons simultaneously.
5. Navigate to "apply update from external storage" using the volume buttons.
6. Select it by pressing the Power button.
7. Select the zip.
8. Wait for it to finish and navigate up (select "../").
9. Select "reboot system now".
6. Reboot and profit! If you boot into recovery by Volume Up + Home + Power buttons, you will now see CWM recovery.



Instructions (Unroot):
1. Download SU-BB-Unstaller.zip from here: http://www.androidfilehost.com/?fid=9390233485161005748
2. Place it in your external sdcard.
3. Power off your device COMPLETELY.
4. Boot into recovery mode by pressing Volume up + Home + Power buttons simultaneously.
5. Navigate to "apply update from external storage" using the volume buttons.
6. Select it by pressing the Power button.
7. Select SU-BB-Unstaller.zip.
8. Wait for it to finish and navigate up (select "../").
9. Select "reboot system now".
10. You are now unrooted.


**NOTE: In order to use this method to unroot, you MUST use my method to root before this.

Optional (remove CWM recovery)(For ICS only):
This is the tricky part, the easiest way is to reflash a whole firmware via ODIN. But if you like new methods, try this:
1. DO NOT uninstall kTool or unroot your phone first!
2. Obtain a stock zImage (either you download it or extract it from a firmware package), make sure that it is meant for the firmware you are using.
3. Place the zImage in the root of your internal storage.
4. Launch kTool and select "Flash kernel from /sdcard/zImage".
5. Reboot and if you boot into recovery by Volume Up + Home + Power buttons, you will now see the default stock 3e recovery.
6. Now you can unroot your device.


Optional (remove CWM recovery)(For JB only):
1. Download stock_XXLSR_kernel.zip from here: http://bit.ly/XCEejd and place it into your external sdcard/internal sdcard.
3. Power off your device COMPLETELY.
4. Boot into recovery mode by pressing Volume up + Home + Power buttons simultaneously.
5. Navigate to "Install zip from sdcard" using the volume buttons.
6. Select it by pressing the Power button.
7. Select "Install zip from sdcard" if you placed it in the external sdcard, or select "Install zip from internal storage" if you placed it in the internal sdcard.
8. Navigate and select stock_XXLSR_kernel.zip.
9. Wait for it to finish.
10. Select "reboot system now".
11. CWM recovery is now replaced by stock 3e recovery, and back to stock kernel too.



That's all from me. Happy rooting!

Really great guide man. Super simple. Will use this to root my gf's 9100G and get her on CM once I get back to India. Especially helpful because she just burned out her USB port by dropping the phone in a toilet so she can't use odin. =_=

Sent from my 9100G, running CM10.1 / Codebox / Slim Bean, depending on the day
