Does anyone know if PICs support Flash-lock? On AVR chips you can set certain fuses on the chip (think configurable parameters in the chips hardware) to lock down the Flash and EEPROM so it's read-only, write-only or even neither, necessitating the need to directly modify the Flash/EEPROM or use a bootloader.
Do PICs support this? If not, or if its not enabled by chance, you can try to do a read-back of both chips Flash to get an idea of what they're doing. Of course IFI might show up on your doorstep with one of those MIB flashy-things...
