Answer
- Tap Settings > [your name].
- Tap iTunes & App Store.
- Tap your Apple ID.
- Tap View Apple ID. You might be asked to sign in.
- Scroll to the iTunes in the Cloud section
- Tap Remove This Device.
1) Connect the iPhone to your computer with a USB cable.
2) Click “iPhone” under Devices in iTunes and select Check for Update in the Summary pane. If you see any red text appear, click Back Up Now to back up the device before attempting to restore it or erase it. You can always restore from backup if things go wrong. Also check for an update for your version of iTunes first from its homepage at www.apple.com/itunes/download/. Sometimes Apple updates iTunes in response to a problem like this so that you have the latest software available if something goes wrong during erasing or restoring your device (because they are aware of this issue). This is especially likely if error 3259 pops up when erasing your device.
3) Click Restore and follow the prompts to restore your iPhone (not “update” it).
If error 1671 happens, you have some form of a corrupt file on your computer or in iTunes that is not allowing you to back up or update this particular device. You should try backing up this device using a different USB cable first and see if it allows you to backup successfully. Then try updating again with the original USB cable and see if that works before attempting any other recovery methods. If you are working on Windows XP, make sure there is no lock icon next to “USB Disk Drive.” And make sure there is no external drive plugged into your computer which has been assigned a drive letter in Windows Explorer. If all this checks out, try booting into Safe Mode with Networking (not Safe Mode with Command Prompt). If iTunes works in Safe Mode, you may have some malware or other programs on your PC which are preventing iTunes from working correctly. In that case, remove the iPhone’s sync settings for now and follow steps 1-5 listed above to erase and restore again. Then reconnect it to your computer and create new sync settings in iTunes to get back all your data onto it.
If any other error happens during restoring like 3259 occurs:
1) Make sure you’re using an original USB cable that came with the device. Do not use a “charging only” USB cable as these cables don’t allow communications between the computer and the device (i.e. syncing) to happen. If you didn’t get an original USB cable with your iPhone, you can order one for $9 from Apple Store online using this link: http://store.apple.com/Catalog/US/Images/galleryplus_iphoneusbcablepdp_a3149tqz4__A1_.gif
2) Or take it to an Apple store or authorized repair center so they can attempt to erase and restore the device for you if error 3259 pops up on their computer when trying to complete a restore of your device onto iTunes on your computer for some reason.
3) If neither #1 or #2 work, then you may have to restore your device into other software or format it and then create new sync settings in iTunes to get back all your data onto it. You can do this by hooking up the iPhone with a USB cable and running DiskAid from www.hackthesystem.com while holding down Option on the keyboard (on Mac) or Shift key (on Windows). In DiskAid, select Open iTunes Backup and find your most recent backup file under Backups in iTunes folder. Then press Restore All Files from Backup button below that list of backup files, which is found along the bottom of the window next to the Trash icon highlighted in red above (“Restore From”).
How do I move my music off my iPhone so I can restore it?
You can export your music from your iPhone by opening iTunes and then going to File > Devices > Transfer Purchases From “iPhone” (i.e. the device name under Devices in iTunes, which is usually different than its actual name on your computer). Then click on Music tab at top of window showing all music files available for sync and drag the files you want onto your desktop or into a folder on your PC’s hard drive. This will transfer all the files that have already been sync’d with iTunes onto this device over to your Windows PC. If you’re using Mac, just copy them off somewhere also (or rename them first before transferring if you prefer) before restoring so they don’t get deleted when wiping out the iPhone’s data.
How do I fix the firmware error 0xE8000015?
The device is locked or signed with a non-matching Apple key, causing iTunes to refuse to sync with it. A simple solution is to erase all content and settings on your iPhone and then restore as new. Also, you can try quitting out of iTunes, unplugging your device, plugging it back in after 30 seconds and trying again if that happens with iTunes during restoring your iPhone iOS. For another fix for this error see: http://support.apple.com/kb/TS1734?viewlocale=en_US&locale=en_US

Or try finding the firmware file for this device (an iPhone 3GS would have a different firmware file then an iPhone 4) on Apple’s website for downloads and download that one instead of using the one you downloaded from iTunes to update your device with initially when trying to restore it. You can find these files by going to Settings > General > About on your device and looking under Model number (as pictured above). This will bring you to a page with several download links listed for all the different iOS versions you can download for this device. Just pick one that looks like it’s a firmware file (listed under Firmware) instead of an iOS version and you should be able to rename it so iTunes will accept the download and do the restore that way as some people have done before with success for this error message. If
you know where on the internet one of these files may be located for a newer version than what’s already available from Apple, please post a link in the comments below. You might also need to check and see if there are any pending iOS updates that have not been installed yet on your iPhone by going to Settings > General > Software Update and checking here as well before trying this method.
If you’ve already tried this and your iPhone still won’t restore, try restoring back to the last iOS version that was successfully working on your device from iTunes. If this worked before doing a restore as new then it will hopefully work again now after trying the fix mentioned above or erasing all content and settings (which will force iOS to reinstall any previous versions of iOS that were still available for download in case you didn’t check out software update). You may also need to turn off Auto-update under Settings > iTunes & App Store settings if you turned that feature on previously as it has been known to cause problems with restoring some devices. It’s also possible an update came out while you weren’t paying attention causing this error message, so try installing any available updates from Software Update before doing this.
Your account might be connected to the device you are trying to delete. To prevent this, sign out from that device and then try again. I only have access for one of the devices but signing out has help for it.
If you can’t click Remove (the button is dimmed), the device you’re trying to delete is linked to your Apple ID. After that, restart the iTunes Store on that device and try again to remove it. Best wishes, dude. Signing out and back in worked for a single gadget I could still access.
It may only be done using iTunes, according to apple support. There’s no need to deauthorize it with a PC via iTunes. Simply sign in to iTunes, navigate to the account page, and deactivate it.
On a PC, open iTunes. Select “View My Account” from the Store menu to view your account information. Enter your Apple ID and password to log in. Select “Deauthorize All” under “Computer Authorizations” for each machine you still have permission for. Each computer you still have permission for should be authorized again as necessary.
Begin by deciding which two phones you’ll be transferring. Go to Settings>iCloud and change all data syncing with iCloud (contacts, calendars, etc.) to Off on these two devices. Choose Delete Account at the bottom of the screen when prompted.
You’re done! On each Android phone, the settings menu may be organized differently, but this is how you do it. Then go to general and scroll down; after that, go to lockscreen and security, then phone administrators and “find my device,” then switch it off.
