An update: See below after hooking the board up again to MPLAB after trying to boot the miner with the non-stock firmware, I haven't confirmed it will work with stock yet but it seems to revert to errors as thierry4wd has pointed out.
The following memory area(s) will be verified:
program memory: start address = 0x0, end address = 0x2b7f
configuration memory
[ Pgm ] at 0x0, expected 0x00040200, got 0x00ffffff.
You have set the program speed to Normal. The circuit on your board may require you to slow the speed down. Please change the setting in the tool properties to low and try the operation again.
