Well I just upgraded my -2 to v20. I was wondering what I can restore from the old v15 fw. I backed it up via content copier. I remember a post saying someone tried to restore v15 settings or user files, can't remember...anyway he bricked his phone.
So what's ok to restore from the following (Content Copier)?
User Files from the Phone Memory
Contacts
Calendar
Notes
Messages
Settings
Bookmarks
Thanks 😊.
