Okay so I flashed the ICS theme over SD3 and everything is great except the camera program disappeared D: I have the modded apk/zip that is posted on XDA. I'm not sure if I should just move the modded apk back to system/apps or if i should reflash the .zip and then move the apk..
I haven't heard of this issue before.
But yeah if you move it back to system make sure to use Root Explorer to change the permissions so it matches the rest, then reboot. If that still doesnt work, try reflashing Steel Droid v2, and then whatever mods you want and you should be fine.
