So, I've had a s21 ultra that I bought second hand years ago and I love it. I don't use as primary because I don't trust google/samsung (I use graphene on a pixel5) but I keep it as stock for the amazing camera.

I made the mistake of making a google account to play games. I just used random letters as I have no interest on it and I'm just being forced for the game to run. Today the phone was stuck on "phone is starting". I tried reseting cache on recovery, but nothing. I figured only factory reset would work.

Now it forced me to login to my @#$@$#%ing google account that I never wanted. It won't let me use my @#$@#$ing phone if I don't know the @#@%@ing google garbage. Is my amazing phone now a piece of brick because google needs to sell my data for my "security"? Is it really gone?

It's recently updated. I don't remember if I unlocked the bootloader (I don't think there are custom roms for it so I didn't bother) but it seems to be locked. Is there really nothing to be done?

I bought it for 1/4 of the price, but it was still a lot of money for me. Totally worthy because the camera is amazing, but did google really destroy my phone for my "security"? I understand forcing to wipe out data, but bricking the phone? How on hell is that for my security?

Just complaining out loud. I know that the answer is the same as "protect from terrorism" or "protect the children" is just really "to give us more money". But anyway, is there something that can be done?

Apple is the same or even worse right? if not, as much as I hate them, I would move. But now... It looks to me that if I want a good camera, I buy a real bulky one. If I want a good processor, I buy a laptop. Nowadays phones need to be just cheap garbage that can be thrown away easily if you don't want to please google/apple....

Anyway, any help is appreciated, though with my knowledge of phones, I think there is none. It's a brick now, that I wish I could throw at some people on google...
