Same problem. I am moving from iphone 4S ios5 to iphone 5. I synced and backed up the iphone 4S; then tried to restore the iphone 5 from the last backup. After the backup was completed, the iphone 5 refuses to start.
extracting and reinserting the connector cable will give me a few seconds of the apple logo and then the phone goes dark. Keeping the power button pressed does the same thing.
I have no idea how to get the phone to start - its looks like its bricked!
ok. I just solved my problem.
The answer was the same old - "Press power button & home button together" until it powers down & restarts.
Here's the tricky bit: During this process, the apple logo starts & disappears as if the phone tried to get going and failed. It does this twice for me (no idea why!). Just be patient and keep your fingers pressed down on both buttons. Eventually the phone restarted, but it took a while.
The same thing happened to me twice last night. After the "please wait for your iPhone to restart" message it just....never restarted. I'd press the power button and the apple would flash on, then nothing. I did the hard reset, still nothing. It was only after I unplugged the phone from the computer, did a hard reset, then connected it back to the computer again that it fully powered on, showed me the progress bar, and became functional.
This does not bode well.
Mine seemed to be ok until I restarted it & the same thing happened again.
I gave up, cleared the phone to factory settings and started afresh. Tbh I prefer this idea, starting without any crap that might be hiding in the system, but it was a shame to lose all my text messages.
The phone has been fine since.

If it doesn't solve your problem.
Here is what I did and it SOLVED! for my iPhone 5:
1. Close iTunes and reopen your iTunes program again.
2. Plug in your iPhone 5 with your computer.
3. Press Power button and Home button together again.
4. This time iTunes will show iPhone 5 will be in recovery mode. Just close the pop up messege in iTunes.
5. My iPhone's screen shows to plug in cable with iTunes. I just remove the cable out from my iPhone instead.
6. Press and hold Power button and Home button together again. It will shows Apple logo first, then disapear, then it shows Apple logo again. At this point, release both buttons.
Under the Apple logo, it will show grey bar (like computer boot up). Just wait and then Voila!. My iPhone came back to normal again.
I did the above processes because I try to avoid from Restore to factory setting.
I hope this help and work with your iPhone as well.
Have a good one!
I experienced the same problem but was able to access the phone with HappyWealthy's method. But has anybody been able to fully restore the phone from a backup rather than just getting acess to the phone? If this issue persists, it will mean that I will not be able to restore my phone from a backup ever.
Lastly, I'm uisng iTunes 11 when I experienced the issue.
My iPhone 5S wasn't charging (got accessory not supported message). Went to Genius Bar. Was told it was corrupted software and to do a restore. Backed up to iCloud. Erased the phone. Restored from iCloud with it plugged in connected to wi-fi. Phone is now brick. No response plugged in to AC. No response plugged into Mac Mini. Mac Mini not recognizing the device. No response when Power and Home pressed together. Ran out of charge? But even so...Ideas?
