So my GS3 just started acting up last night and the power button is now ridiculously sensitive, to the point where its really not usable. I called Verizon and they're sending me a new unit this week, but my issue here is I don't know how to return the phone to stock when it seems like even touching the phone could cause it to turn off, and I can't exactly send a phone with CM 10.2 back to Verizon. Does anyone have any ideas of how to deal with an issue like this?
EDIT: So it turns out with enough rebooting there was a small chance the phone wouldn't shut itself off when in download mode or recovery. So after rebooting about 100 times I managed to make a backup to the SD card and flash my phone back to stock. The button is still messed up, but now I can return it. Just in case anyone else runs into this and wonders what I did.
