Well, physical damage is the only way to brick this board.. > I'm now trying to decipher the User LED blink codes to understand the device > state and where things may have gone wrong.

The only real LED blink code is on bootup, a solid pattern [] [] [] [] - off [x] [] [] [] - on, starting mmc scan... [x] [x] [] [] - scanning mmc... [x] [x] [x] [] - processed boot script... [x] [x] [x] [x] - jumping into boot... Beyond that, the "flasher" does a cyclon pattern... Otherwise the led's are just software triggers in linux controlled by gpio: usr0: heartbeat usr1: mmc0 usr2: cpu0 usr3: mmc1 If they stop, the core stopped..
