Iphone4 wallpaper folder problem on 6.1.3

Go to Settings>Birghtness & Wallpaper then Tap on the screen that shows the black wall paper this will then give you a choice of selecting a photo from your photo albums or camera roll or the first option which is wall paper gives you the default wallpapers in iOS, Are they all black there?

Sound like the update might have not installed correctly. I would backup the device then restore as new via itunes and see if you can see the wallpapers with out restoring your backup. If all is well and you can see them restore from backup to get your information back on the Phone and see if the issues persist.

Yea since the restore worked go ahead and restore from backup and see if they stay there.

Sorry to hear a simple fix might be to reset all settings on your device to see if they come back if not there might be something in the backup causing the issues. try going to settings>general>reset the reset all settings let me know if they come back, if not you will need to restore as new and resync and reimport your data to your iPhone.

At this point Kool looks like the issue is in the backup, if resetting your settings and resetting the phone did not fix in order to fix we know we need to restore the iPhone as new, if you are using icloud you contacts, notes, mail, calendars, etc will come back with no issues, but apps will have to be redownloaded and music and movies and other items that you had syncing via itunes will need to be resynced. you can always try to wait till another update to see if that fixes it and just live with the issues for now, but it might not fix it still. i would restore the iPhone and follow my instructions as above and when you have you iPhone the way you like it make a new backup in case situations like this occur again in the future.
