See if you can force the phone into recovery mode:
Turn your phone off. Leave the USB cable connected to your computer, but NOT your phone, iTunes running, press & hold the home button while connecting the USB cable to your dock connector, continue holding the home button until you see “Connect to iTunes” on the screen. You may now release the home button. iTunes should now display that it has detected your phone in recovery mode, if not quit and reopen iTunes. If you still don’t see the recovery message repeat these steps again. iTunes will give you the option to restore from a backup or set up as new.

HT4623 on upgrading iPhone 4 to ios 6 using itunes it returned an unknown error then froze completely. It has the iTunes and USB connector on the screen. Reset is not working, I get the same frozen screen.

On upgrading iPhone 4 to ios 6 using iTunes, it returned an unknown error then froze completely with the iTunes icon and USB connector on the screen. Reset didn't work. iTunes doesn't recognize the devise anymore.

if your computer is not recognizing it, try using a different USB port or different usb cable. if that doesnt work you will need to uninstall and reinstall itunes.

Upgraded iPhone 4 to IOS 5 the default tones are all cut?

I upgraded iPhone 4 to IOS 5 the default tones are all cut short now example is the choo choo just does a single choo. Also all of my custom ringtones were all messed up had to replace them too.

I was searching around to find out why this was happening to my wife's phone after the iOS 5 upgrade. Kinda really sad on Apple's part. Almost all of the text message tones sound broken now. We thought something went wrong in the upgrade. Too bad.

After upgrading iphone 5 to iOS 7, I cannot install new apps

After upgrading iphone 5 to iOS 7, I cannot install new apps. I get the message that I must first read and agree to iTunes terms and conditions. I read the terms and conditions online, but I don't see a way to agree when I install or re-install iTunes 11.1. I can update existing apps ok, though.
Anyone have this problem and find solution?

Delete & ReInstall the App Store...

I upgrade my iPhone 4 to iOS 7, but cannot restore the backup "error when restoring iPhone (-1)", anyone know what should I do?

That error often indicates a hardware failure.Try restoring a few more times. If it consistently gives you that error, make an appointment at the genius bar to have it looked at.

HT4859 After updating my iPhone 4s to iOS 6.1.2, the iCloud backups fails

After updating my iPhone 4s to iOS 6.1.2, the iCloud backups fails. It appears it is trying to backup the entire 3.1 GB not just new data, thereby exceeding the 5.0Gb limit. I have checked the phone contents on my iMac and there is very little new data so the backup should be successful. I have tried rebooting the phone, which did not help. Phone is not jailbroken. Any suggestions? Thanks....

I have a similar problem, but after following your suggestion of deleting my iphone backup and then turning backup back on again, I needed to plug my phone into my computer to sync the backup. I re-tried to do an icloud backup and it again told me that "the last backup could not be completed"... since I had deleted the backup, it says the "Last backup: never". Ugh. I reconnected my iPhone 4S to my computer and iTunes so I could sync my phone and do a backup... it's still "waiting for sync to start"...
For your iCloud backup, you may have an app that is preventing the backup from succeeding. To locate which one, go to Settings>iCloud>Storage & Backup>Manage Storage, tap the name of your device under Backups, under Backup Options tap Show All Apps, then turn them all to Off (including camera roll) and try backing up again. If it succeeds, then the camera roll and/or one of your apps is preventing the backup and you'll have to located by process of elimination. Turn the camera roll On and try backing up again. If it succeeds, turn some of your apps to On and try backing up again. If it succeeds again, turn some more apps to On then try again; repeat this process until it fails. Eventually you'll be able to locate the problem app and exclude it from your backup.
If you turned iCloud backup off and try to sync to create a backup on your computer and got a "waiting for sync to start" error, it may be caused by a corrupt backup on your computer. You could try deleting your last backup by opeing iTunes and going to Preferences>Devices, clicking on your last backup and clicking Delete Backup. Then try again.

Upgrade iPhone 5 to iOS 7.1.2

I've helped a friend with her iPhone 5.
After upgrading to iOS 7.1.2 and reboot the iPhone don't start up it get stuck with showing the white Apple logo.
I tried using both the recovery mode and the DFU mode in iTunes to restore/reset the iPhone but the problem still remains.
(The iPhone goes through the upgrade/reset phase showing the usal progress bar on the iPhone.)
I then donwgraded to 7.1.1 using iTunes holding the shift key (Windows) and clicking the upgrade button and selecting the ipsw file for 7.1.1 which I've downloaded.
After the iPhone reboot the problem remains i.e. only the Apple logo shows up.
I then disconnected the iPhome and let it discharge compleatly.
Then I connected the iPhone to iTunes and after the iPhone have charged enough it started up in the same state a new iPhone and it works OK.
I then upgraded to 7.1.2 and the old problem came back i.e. only the logo.
Doing downgrade to 7.1.1 give me once again a working iPhone.
Both me and my wife are using iPhone 5s and had problem while upgrading to 7.1.2. A hard reset (home and power) solved the problem.
These upgrades were done directly in our iPhones.
The iPhone having the problem have sn C39JTC3YF39C model MD662KS/A.
Do you know what could be the problem and what to do about it?

See this support document for help with updating the phone. If you can't update or restore your iOS device
Your attempt to downgrade the iOS, which is not supported by Apple, could have caused some of the issues. You may have to place the device in recovery mode. The support document will explain that to you.

HT4972 After upgrading iPhone 4 to iOS 5.1.1 getting the error "iTunes could not restore the iPhone because the backup was corrupt or not compatible with the iPhone that is being restored" HELP!

I attempted to upgrade my iPhone 4 to iOS 5.1.1. I selected 'back up' from the phone in the device menu and iTunes confirmed that the phone had been backed up. I then installed iOS 5.1.1 which wiped everything on the phone & now I am getting the error "iTunes could not restore the iPhone because the backup was corrupt or not compatible with the iPhone that is being restored".
I have tried restoring factory settings but iTunes simply will not restore from back up & I'm not sure what else to do!
Any advice would be much appreciated.

I have the same issue and I KNOW my backup IS good. What happen is when you try to restore your phone apple says something like can I check for new updates and if you choose no, it just takes you back to the restore screen and a loop from then on. If you dont update from you phone then when you back up you will have the 5.0.1 back up and then when you update to 5.1.1 and then try to restore the backup from 5.0.1 it say it EITHER corrupt or incompatible.. It is incompatible and its hard as **** to restore back to 5.0.1. I followed the restore to a T and still getting errors. I lost all text history and have to reset up email. All just because I wanted a 1.2 Gigs of "other" space back.
