Nope, no backups at all. Phone showed "Device is malfunctioning!", so I downloaded stock image and ran "flasher -F <image> -f -c", waited few minutes and boot up phone. Almost everything was there. Missing stuff: favorite flag for contacts, passwords to accounts (MfE, CalDav, ...), all 3rd party applications and settings. But music, videos, contacts, messages, emails, etc. were untouched.
