I'm sorry to hear that.
I had the feeling it was inevitable but I was holding out hope that there was a way to stop the updates.
I'm thinking of flashing a third-party ROM and rooting that and never updating after that if it's possible. I have no need to chase updates.
If you're using a Metro phone please let me know what solution you come up with for your phone.
I actually have a bunch of N100s free from work that are TM and Metro. Gave up on them because of this blocker. Can you help me figure out how to do this third-party ROM idea? I'm happy to try it. I also have no need to chase updates.
