I am one of those people that flashed the wrong firmware "update" on my 5201. My deck boots now but it self-identifies as a 4200 and half of the features don't work. It's... not great.
Would very much appreciate a virgin 5201 firmware image. Don't even care which FW version at this point. Anything to save me from shipping this thing back to Pioneer HQ would be fantastic.
Please and thank you.
