i was using a custom rom which was running 2.1 and then tried putting a custom 2.2 rom on and it wasnt working right so i tried to revert back to the 2.1 and now im stuck on the m loading screen. i thought i bricked it completley but i was told that if i can still get to the nandroid screen there is a chance it could be fixed. i am still able to get to that screen but im not sure what to do from here. any suggestions or am i completly bricked.
