"Power Button Broken" için yanıtdudes !! i've been trying to enter DFU mode for months now. my Power Button is completely out ! today i opened up my iPhone 3g just to see what's inside and when i closed it up, i was touching it and i accidentally pressed the screen at the earpiece (the thing where you hear people talking to you) and it locked ! i thought 1 minute has passed but i tried again and it worked ! it worked when i tried to turn it off, it worked when i tried to turn it on AND it worked when i tried to enter DFU mode ! i just wanted to share, maybe it'll help someone out !
