Hey peoples, ok, so here's my issue - I have rooted sg4 on sprint, and it's been working fine, but yesterday it started acting weird and basically just turning off out of nowhere. If I took out the battery, the second I put it back in, it would boot right back up, but then immediately shut off, and i wouldn't be unable to do anything. I currently use an Otterbox case, and i have a feeling the case screwed up my power button, by making it permanently "pushed in" (my wife had similar problem w her otterbox and iphone)...anyway, i took my phone to sprint store, and they took it apart and said there was no hardware issues (specifically with power button), but they couldn't run diagnostic tests because the phone is rooted, and would need it to be un-rooted in order to run a test....problem is, I can't unroot, because i can't turn on the phone! Anyone have any ideas??? suggestions? gracias
