Member: 65926 Status: Offline Thanks Meter: 1 | Iphone 3gs goes into DFU after unplug My iphone goes into DFU after unlocking I recently downgraded my iphone 3gs to 4.3.2 and upgraded to ipad baseband. 1. Restored with iPhone2,1_4.3.2_8H7_Custom_Restore 2. T- boot with redsn0w_win_0.9.8b4 3. Update cydia 4. Unlock with ultrasn0w via cydia All this time cable plugged in. 5. Open itunes and sync 6. Unplug cable and after about 20 or so seconds, screen black out and went into recovery or DFU mode. Not able to t-boot or restore at this point. This is the second time it happened with same iphone. I was able to restore with same custom firmware after the battery was drained (roughly 1 week after). Any suggestions would be appreciated. |

Member: 65926 Status: Offline Thanks Meter: 1 | There is no error code iPhone just goes abruptly into recovery/DFU. After I downgraded and restored the custom firmware and t-booted, it came up fine. I was able to install ultrasn0w and unlock fine. I actually had it up for the better part of a day with no issues (plugged in). As soon as I unplugged the cable, it went into recovery/DFU. No errors, no warning. Just went black. When I plugged the cable back in, itunes gave the message that it has detected an iPhone in recovery mode you must ..... All attempts to t-boot or itunes restore fails. Get the "waiting for the phone to reboot" in redsnow and "Itunes is prepareing iPhone for restore", in itunes. Just simply hangs there. (needless to say in recovery/DFU) So yeah that's my dilemma. I have no Idea what the prob is here. Last edited by peelaz; 10-12-2011 at 20:16. |

Member: 65926 Status: Offline Thanks Meter: 1 | Ok so I disconnected the battery and was able to boot restore the custom firmware. Now the screen doesn't work right. Prob pulled out something in the process. After I unplugged it again from the computer, the same thing happened again. The screen went black and it went into DFU/recovery mode. |
