Flashing Apple logo - does not come on and cannot power it down

Question

My husband has original iPhone from Dec '07. For some reason, while using it, his volume went low and he could not raise it. He tried powering it down to reset it but screen went black and then apple logo came on, then went black, then came on, flashing like that for several minutes before going black. He brought it home, i tried holding the sleep/wake button, but same result - flashing apple logos for few minutes, then black. Tried holding home button but also same result. Plugged into computer - it came on but the "Sync in Progress, do not disconnect" did not come on and phone did not register on desktop even though iTunes showed it. Anyways, did a complete restore with most recent software but again, we're still having the same problem. Phone works when plugged into computer, but not in the way it should and once you unplug it from the computer, sleep/wake button does nothing and cannot power it down. After restoring it, i again tried to power down holding sleep/wake button, but got flashing apple logos again. Any suggestions? Do we need to just take this in and have it looked at?

Answer 1

Have you tried booting it to recovery? If you haven't, try these steps:
1) Close iTunes and unplug and power down your iPhone
2) Press and hold the home button
3) Keeping the home button held down, plug your iPhone into your computer
5) Keep the button held down until a recovery screen with a pic of a USB cable with an arrow pointing to an iTunes icon shows.
6) Open iTunes and perform a restore
If this doesn't solve your problem, you have to go to an Apple store and get it exchanged, as the above post said.
