Oh boy, I just spent last couple hours to 'fix' my upgrade problem with no happy ending. The unit was working fine until this firmware upgrade. It is properly displaying the latest firmware number but the sound is total garbage. Something must be went terribly wrong during the firmware upgrade. I am not sure what is my option other than give Outlaw tech support tomorrow. I hope it can be repaired and I will be out of pre/pro for few weeks, I guess.
