Hi there and welcome
When it failed in itunes, what error did it give? And how did you initiate the reboot?
Please let me know
No problem, can you on the phone hold the home and power buttons for about 10 seconds until you see the apple Logo, then release
Tell me if it then starts correctly please.
ok, now wait and tell me what now happens please.
ok, no problem, but is the phone now working?
maybe it is easier if I call you?
ok, that can be normal. When it turns on is it at a functional state?
How long does it take to turn on?
no, thats not normal.
Can you go to settings, general, reset, reset all settings.
Once done, tell me how it now operates please.
If you have continued problems, or would like any additional information or assistance, please do not hesitate to let me know.
