Guess a lot of folks having this issue. So my story begins earlier tonight when i was in the middle of Subway Surfer and the screen went completely blank. I think i was at 47% battery power when it happened too. i can hear it click, it vibrates, i tried turning it off and it will vibrate and iTunes can pick it up, it will charge as well. the apple logo will flash for a quick second with it reboots and that's it...i've had it plugged in for the past 3 hrs and still nothing...i can blindly turn my music on but can't pause it so i have to turn it off again and the screen is still black. i'll try restoring it later and see if that works...
I was working today, had my iphone4 in my pocket, looked at it and it did not turn on. I said, this is weird,it's to early to have low battery. Then tried to connect it to the wall and never turned back on. I got really worried, went trough some forums here and other websites and there seems to be a relationship with the **** IOS 6 update.
I updated it last night, everything was fine. So I held down the Hold button and the Home button, both at the same time and after 20 secs, the apple logo was on the screen. I took almost a minute back it came back to normal. My battery was at 63%. I have NO idea what happened or what that was...
I hope it'll continue to work !
Good Luck guys!
So all of this advice is solid and needs to be done in order to get out of this loop/dead battery after upgrade problem. I basically left my phone for dead, bought the 5 and decided to try and resurrect it recently to use as iPad/iPod.
Once I got it out of the recover loop using Tiny Umbrella my iPhone would get to the step past picking a language during initial/new iPhone setup and then ask me to connect to iTunes. (This was ONLY if connected to wall power.) As soon as I would disconnect wall power to plug into iTunes it would die. I played with it for days! I ordered a new battery, replaced it, no good. You will never believe what finally worked.
1. Take the back off and disconnect the battery terminal (leave battery in)
2. Leave disconnected for 1 minute
3. Reconnect battery and then plug into cord attached to computer (LEAVE THE BACK OFF)
This should allow you to setup as new iPhone and all will work well. I was so happy, then I put the back of the phone back on and when I hit the power button to make it sleep, it would not come back on again...back into same loop. I realized that if the back was off all worked well. Then I realized that there is a little spring connector by the battery conneciton that has a contact point on the back of the phone. So, I put a piece of electrical tape on the back of the phone over the contact point, close the phone and BINGO. Works like new. I have no idea what the contact point and spring piece do and will let someone else weigh in on that issue. Hope this helps someone out there.
