I have a client with a iphone 6S plus that backs up using itunes on a windows 7 desktop.
For some reason, when he backups to his computer, not only does it take a long time (15-20 minutes sometimes) but he would randomly get the error:
"The iphone could not be synced because the connection was reset" when the backup is finished.
I have so far tried the following:
- Uninstall and reinstall itunes (latest version).
- delete backup folder.
- Replace sync cable with a new one.
- Changed USB ports.
- Uninstall and reinstall drivers (for the iphone under device manager).
- delete the lockdown folder.
All this doesn't seem to work as it keeps doing the same thing where this error would randomly popup. Any ideas what else I should try?
