modem, recovery and eventually bootloader, look at my signature for details you need...
Thanks very much. I did all you suggested... the new rom is installed... but now how to restore the backup? before to flash this rom I did the backup with samsung account and google account in phronesis 6.0.1 (I've also the nandroid backup)
- Google account doesn't propose me to restore the backup (maybe because is not possible restore it in nougat coming from marshmallow?)
- Samsung account doesn't exist (how to access in it?)
