#mod-build number shown within setting/about. add whatever after the =

Anything with (ro) is a running system variable you must reboot to take affect.

Within root explorer navigate to system/build.prop make sure you toggle ro/rw in the top right corner. long press build.prop until a menu appears select open with text editor proceed to add or change variables you've selected from above. When finished save&exit. Root explorer will back up the original.

Please pm me if you have any feedback or additions to this list.


Feel free to use this in anything you want roms/mods/flash-able zips whatever. PERMISSION GIVEN cause what are we without open souce.

This is pretty cool. I am not a developer but I am impressed by the level of detail in customization... thanks for the info..

Build.prop edits not development? Its just not a flashable zip like the rest supercharger script etc.

Thanks voidthedroid just trying to show people how to mod there own buildprops not just flash something, not that there is anything wrong with that. This way you can pick and choose which mod is right for you, You ultimately need to decide what you want to put in your build number segment i don't think i could make a flash-able zip do that.

Open your build.prop and add the lines. Save and exit. Reboot twice.

WRONG.. you dont ADD the lines. You EDIT the ones that are already there. just find the corresponding line, edit it to the value you want (after the = sign, usually) then save, and reboot... root tools has a build.prop editor that works real good.
