I've H/W unlocked a few phone already but after doing testpoint on this one and getting ready to Restore to 1.1.1 the phone simply just shut off.
I tried pressing Power button, Home button, Power and Home button together for who knows how many seconds, even minutes, and NOTHING. I plugged it to computer with cradle and just the cable for a couple of hours, NOTHING. iTunes or IBrickr obviously won't recognize it since its shut down.
I figured, my iPhone is just dead, so before packaging it back up I said let me try soemthing else. I grabbed the wall outlet adapter and plugged it to the wall, Voila! it turns on, I can even go to Restore Mode, I figured GREAT it's just a low battery! I left it there overnight, a good 10 hours. Came back in morning saw that it was still on, disconnected from wall and it shut down and wouldn't turn on again, WTF! i thought. I tried the whole, power button home screen button BS for a good minute and nothing.
Bottom line, this phone just wont turn on unless I plug it to wall. Cant do restore, cause obviously it's not plugged to computer. What do you guys think? Bad battery? Anyone experience this?
This means the power protection circuit tied to battery is no good.

It'll help you resolve this issue, worked for me. Don't fear soldering either, just go to Radio Shack and buy a soldering iron for $15, took me all but 5 min.
