IPhone won't turn on after a restart?

It did suffer some water damage a couple weeks ago so I'm guessing that's the reason why. When trying to power back on, the logo just comes up for a bit and then disappears. Will I need to put it into DFU mode?

Added (1). Or can it not even go into DFU mode since it's already off?

Added (2). I just chatted with support. Since my phone is in limbo, I'll have to go in person. The indicator doesn't show it has water damage though so that's good.

If you have apple care you can go to their store and fix it i'm pretty sure.

Call apple

  • Why does Pokemon Light Platinum restart after I finish catching my opponent's Pokemon? So I'm currently playing Pokemon Light Platinum on GBA4IOS Version 2.0 on my iPhone. I wanted to use this cheat which enables me to catch my opponent's Pokemon. It worked the first 2 times, but my game restarted when I successfully captured my third one. Same thing happens every time I try to redo the whole process. Can someone please explain to me the reason for this and help me remedy this situation as soon as possible. 10 points for the best answer!

  • My iPhone won't stop respringing after I turn it off? I recently jailbroke my Iphone 4 with redsn0w. Every time i turn my phone off then back on again it shows an all black screen with a loading wheel. After about 5 seconds of this it goes back to normal, then 5 seconds later it goes back to the wheel and repeats. I can fix the problem by rebooting with redsn0w, but every time I turn it off it goes back into the wheel routine.
