Hi, i have restore my iPhone 3gs for make the update, when during the backup iTunes show me a message ERROR Applebackup.exe and Applehelperupdate have terminated to work. iTunes continue to work, erase my iPhone and after my iPhone it's empty. Why when iTunes find one error for make a backup do not interrupt the restore procedure? After when i tried to restore my backup i have received a message with error not recognized(-32) and my backup do not work. I can restore with my backup? It's my backup corrupted? Can i restore my backup? Any solution for this error?
you might want to do a hard reboot on your iPhone (hold sleep/wake and home button untill it shuts off), also restart your PC or Mac. Do not open any other programs on your PC or Mac when its back up. then try again and see what happens, hope this helps.
