I literally have tried everything. i replaced my lock button on my iphone, and when i went to turn it back on it wouldnt start. So i plugged it in to the computer,and it now in a power/ reboot loop. My phone will not restore, or reboot, I have tried a manual restore and i have tried tinyumbrella, red snow, snowbreeze, ireb, ibooty. nothing works. I have tried everything it will go into DFU mode but when you reboot it, it wont because it then kicks its self in to the apple sign loop again. Can anyone help? Apple wont do it so I have no hope my phone wasnt even jailbroken.
