The night before last my iPhone's battery was running low, and it appeared to die. However, the back light remained on. The next morning when I woke up, the back light was still on, but my phone responded to nothing I did to it. I attempted to restore it in iTunes, but I kept receiving error messages (1600, 1601, 20, 21, etc). After hours of web searching I have come up with nothing, but I have been able to restore my phone using RedSn0w. The screen remains black when it is plugged into my Mac, but iTunes does recognize the phone. When plugged in to the computer, the phone makes the same noise it makes when first connected and charging to a power source, but it makes this noise about every seven seconds. When I look at the crash report for my phone, it shows: SpringBoard_2012-06-27-144221_iPhone.crash (with different dates/times for each crash). Also, when plugged into my computer, the iPhone screen will occasionally respond to the swipe to return to the home screen. I have a feeling that if I could COMPLETELY wipe everything except factory settings from my phone, that my problem may be resolved. It is just an issue because I can't do this on my phone. Not sure if it is relevant, but I did replace my screen about a month ago. The replaced screen has given me absolutely no problems (unless this problem counts). Any and all advice would be great!
