I'm guessing there is a finite risk of bricking the player, in which case you'd have to confess to OPPO what you've done and send it in for repair.
I'd try it if it were mine, but I have backup players.
I'm fuzzy about erasing the mod. It came up in the -93 thread as some side effect of installing a hardware mod. Installing new main firmware does not erase it, but I suspect new Loader or MCU portions might.
Everyone note: the Superdisc mod is for region free DVD playback on the BR players. It does not enable region free BR playback.
