So before you go to play with these modified files keep in mind that everything from here is custom thing and you installing these things on your own risk! I no want and I will not be responsible if something go wrong, if you lost your private data, if your device can not boot ...etc...etc, you doing everything on your own risk!!! If you no want to risk than skip this thread!!!

Tip and tricks for my CWM version:

Did you know about our CWM that you can change menu and text colors, backgrounds? Yes you can do it by puting menu.txt into ramdisk /res/images folder by writing to menu.txt for example:

122 122 122 255 255 255

First 3 numbers is rgb color for menu and seccond 3 numbers is rgb color for text !!!
