I'm stuck on OneUi6... unwillingly.

So apparently I can't and won't receive ANY future software updates/security patches. Yeah, this fucking sucks. Explanation: My dad got this s22 base at&t version in the usa. It was boxed and brand new and he sent it straight to Bangladesh (to me) and the first stratup happened here. Now after some intense digging I found out that without being white-listed on AT&T server (be an active user of AT&T) I'm not gonna receive updates. I'm permanently stuck with the software + security patch it first came with. Unless I use third party firmwares to force update. rip... 😔
