Did I brick the board somehow, or is it possible that coreboot bricked it somehow? I don't understand, what part of the board could have been damaged here. Short circuit?
There could have been a short when you inserted the new flash chip with coreboot, but then you would not have gotten the one start with the colorful display.
You could check the capacitors on the board for leaks - several on my EPIA-M board have leaked and the board doesn't start, but that's not likely because of coreboot, rather because of bad capacitors.
