I know this doesn't help but I had a curve come in today that wouldn't power on. It would just blink 4 times in a row. I exchanged the battery with one of ours and now it blinks twice. Dm and crack util wouldn't recognize the bb, but loader started to load the os. The craziest led error code I have ever seen was a PURPLE LED on a bricked pearl. I tried everything I could think of but I could not load an os to that one.
