I recently have a malfunctioning power button so i tried remapping keys in my samsung galaxy tab model SM-T210. I edit the gpio-keys.kl and change the key 116 from "Power" to "Volume Up" and also change key 115 from "Volume Up" to "Power"... Then i restart the phone but it wont open. Anyone the could help me please

If you can access it with adb, you can get the file to the PC, edit it (make sure it's an editor that handles Unix line endings) and put it back - then it should be back to where it was.

If not, I have no idea without having the tablet in my hands. (It depends on exactly what "won't open" means, and the results of trying different things [mostly with adb].)
