I’m using Samsung HK ROM (Android 4.04 IMM76K). I don’t want to wait 2 months or more to get Jelly Bean, so I decide to go back to Google ROM.

To do so, I need:
1. Nexus Root Toolkit v1.5.2. Download here: http://www.wugfresh.com/dev/nexus-root-toolkit
2. Google ROM (Android 4.0.4 IMM76I). Download here: https://developers.google.com/android/nexus/images#yakju

### To do this upgrade, Samsung warranty may void. Please take your own risk ###

Steps:
1. Backup personal files from mobile to computer (i.e. copy photos, songs, videos, documents, applications that is NOT install through Google Play)
2. Install and run “Nexus Root Toolkit v1.5.2”

3. Install Samsung Drivers
   - Click button "Full Driver Installation Guide - Automatic + Manual"
   - Click button "Launch USBDeview"
   - Choose any device which is related to Galaxy Nexus or Google, and then right-click and choose "Uninstall Selected Devices"
   - Close "USBDeview"
   - Go to Step 2 and install Samsung Drivers

6. [Optional] Run temporary ClockworkMod and backup Samsung ROM. Inside CWM, you need to follow screen instruction to backup. After finish, you need to turn on mobile again and copy the backup files to your computer (folder: \clockworkmod). Backup includes boot image, recovery image, system and internal data.

7. Load Google stock ROM into mobile. You can choose the ROM that you download before or download directly from this program

8. After 5 – 10 mins, the ROM becomes to 4.0.4 (IMM76I). You should reset your phone once
9. After reboot, set up WIFI and receive Jelly Bean 4.1.1 updates
10. After reboot again, you should reset your phone. You can do the [Optional] “OEM Lock” again to lock the bootloader again from Nexus Root Toolkit v1.5.2
11. Enjoy

## Reset phone is to make sure everything is clean after loading ROM

我之前用1.4版升級4.0.4,再OTA上4.1.1..
呢個Post應該加精,同埋要定期更新.

唔該 bebird 兄
尋晚研究上面資料
小弟可能資質平傭
想問下如果按 10. 做埋 “OEM Lock” 後
是否等同完成私生子變身成親生仔過程
行番原廠設定無 root?

咁如果, 唔 “OEM Lock”
都係親生仔, 不過係 root 左 ? ...

Step 7 will make any root-ed phone to unroot. If you need to root, you can click "Root" button on the main screen of "Nexus Root Toolkit v1.5.2".

Step 10 “OEM Lock” is optional. It just makes user can't change the bootloader. If you don't do "OEM Lock", you can see the "Un-Lock" logo during startup of the phone and you can do "root" later. The performance and function of phone is same for Unlock bootloader or Lock bootloader (i.e. OEM Lock)
