Forgive me, the last time I upgraded my radio was when 2.05 was released (1.0 -> 2.05), so I'm not sure if risks are the same given that we now have S-OFF. Previously (when I upgraded) there were bricks that would occur if the same radio was flashed twice. I cannot remember whether the method of radio upgrading was done via HBOOT or Recovery. If the risk is still there, can I upgrade from 2.05 to 2.15, or should I downgrade to 1.0 then upgrade? As far as HBOOT goes, I have never upgraded my HBOOT, I'm either running on 0.77 or 0.79, but I want to play around with some of the newer roms. Regardless, is HBOOT 0.92 an official release, or is it a user contributed release? If anyone could point me in the right direction, I would really appreciate it.
