I was finally able to complete the update. It must have been a problem with the micro sd adapter i was using because when i put the sd card in my phone and copied the files over it updated no problem. No bluetooth still though, when i go to the hidden screen on the service info screen it shows bluetooth firmware version as ----. when i try to update the bluetooth seperately it errors out after 5 min or so. Im thinking the hardware for the bluetooth died, i ended up just buying a new head unit anyways but i might send this in for repair and keep it as a spare or just sell it to someone who want
