I've bought an unlocked phone but I still haven't got the update to android 10
Hi! I bought this cellphone (galaxi s10+ AT&T) from second hand so I don't have any account from at&t. It's unlocked for any carrier. But I still haven't got the update to android 10, what could I do? I was thinking about downloading a firmware through Sammobile and flash it with Odin but I don't know if it could get blocked to any sim card.
