There were some bugs found in this ROM and it would be better if you’re an advanced Android user who wishes only to test this custom CM9 firmware.

Read the guidelines below and only afterwards you are free to move to the ‘how-to’ guide:
- Domination ICS CM9 custom ROM can be installed only on LG Optimus 2X P990 smartphones. Do not attempt to flash Domination O2X on any other Android device.
- In the how-to guide you’ll find a step that tells you to wipe all smartphone data and this means that your important files such as videos, audio, photos, bookmarks etc should be transferred to your phone’s internal / external sd card. The internal sd card and the external sd card won’t be changed during the update and your files will be safe against removal. Alternatively, you can move the files on your computer via USB connection cable.
- Create a full backup of your currently installed ROM using ROM manager, CWM Recovery, ROM Toolbox Lite. This backup will prove to be helpful in case you don’t like the Domination CM9 custom ROM.

Download the app you wish to use by clicking its corresponding name: AppBAK for Android apps backups | SMS backup & restore | Call Logs backup & restore | APN Backup & Restore.
