just a quick report from me, i got the update for my 64gb black austrian variant 059J1V4 OTA just now, checked navifirm, but its not there yet for flashing for my version. It just booted up after updating, the only thing before updating was that i uninstalled fastern9 and homescreensettings. Apparently there is a Nokia link update for the phone itself (looks like to be teh installer thats copied over to the pc after connecting the phone to it). as of now it seems to work fine (2 mins test)
