jackUY Posted August 14, 2020 Report Share Posted August 14, 2020 Some weeks ago I tried to update the firmware of my recently bought Pioneer AVH- X4800BS following the whole steps included in the guide. Progress bar went from 0 to 100% in some minutes and then rebooted. After turning back on, the screen just remained black. Buttons light up, screen also, but shows even no Pioneer logo. I tried to access testmode by copying the testmode.key file into a formatted USB drive but it does not react to it. I don't have the stock firmware, I would really appreciate anyone's advice/help... Please.... Quote Link to post Share on other sites
