Member: 1676326 Status: Offline Thanks Meter: 1 | Iphone 4 logo 1 sec then off I was testing a new screen for my iPhone 4, and after reinserting the battery the screen flashed with Apple logo for 1 sec and then the phone turned off. It is dead untill I remove battery and then it does the same. Without battery and into the computer port, the screen does the same. I put the motherboard into another iPhone, but the problem is the same, so I guess the problem is with the board/software. I can put the phone into DFU mode and iTunes finds it but without serial and screen only show a logo shortly and then turns off. When trying to restore I get an error 21. Please help. |
