@big_biso, got it, thanks! Sideloaded from NOF26W to NOF27C, after that immediately got a notification about the available update to 7.1.2.Can only hope the same does not happen in the future... Thanks everyone!
How could you sideload without having to "fastboot oem unlock"?AFAIK, if you "fastboot oem unlock", you lose everything on the phone and then you have to restore from backups.
