Need some help on what to do. I recently updated my phone to 4.0.1 then it felt REALLY slow, but i was able to unlock t mobile for it. It was so slow so i attempted a downgrade, and got stuck in the recovery mode loop. I got out and made it to 3.1.2 but I wasnt able to get any service for t mobile, it would just show the signal strength as 1 tiny bar the entire time. So I retried activating but it didnt work. When i restore, when i get to the slide to unlock screen i still have that same icon on the top left, the signal strength is 1 bar. I get error 1015 when I try to go to a 3.1.3. I used ireb, sn0wbreeze, pwnage, and a handful of other things to try to get my phone in the 3.X and unlocked for T mobile. I tried using blacksn0w for activating. When i was 4.0.1 I used ultrasn0w and it was successful, but when i try to add repo___ in sources i get a bunch of cache fail and that sort of pop ups and stuff. Any help?
