Hi,

I suddenly woke up to my iphone logged out of all accounts (fb, twitter, instagram and email), it is also really slow and keeps crashing

Im trying to backup my iphone and upgrade the IOS, but unknown error-0xe80000015 keeps popping
I tried everything (changing the cable, uninstalling and reinstalling, deleting lockdown folder) but nothing seems to work

Yes, I tried all that but unfortunately non of it worked. I even tried on 3 different PCs

 

[now i see it]

You don't want to backup whatever mess is in your phone because you don't want to restore a phone from that backup.
Backing up is too late. The time to do a backup is when everything is working perfectly, not when the phone is acting erratically and crashing.
