So I switched to the 2.2 leak and decided to do the .sbf method to get 2.1 back because I thought 2.2 was a bit buggy for my tastes. Unfortunately, when I had gotten 2.1 back on my phone, I could not activate. It simply said it cannot do it. I tried switching back (again) to 2.2, same problem. Tried manual user activation via ##7762726, still nothing. Anybody have any ideas?
