socci4 Posted May 12, 2013 Report Share Posted May 12, 2013 Hi All, i received a notification from Pioneer about iPhone 5 update availability (i've an european AVH-8400BT). As i've got an iPhone 5, i downloaded the ZIP and followed the instructions. Step 1: BT Firmware -> OK! Step 2: First file -> OK! Step 3: Second file... I put the USB flash drive in, demo appeared, so i pressed menu button. The demo crashed. I had the part about the "MIXTRAX" feature freezed on the screen. I pressed the RESET button on the unit and... booom! The unit doesn't power up anymore. Black screen. Completely dead. Nothing! I checked the fuses and they're ok. I tried to disconnect the unit and then reconnect it. Nothing. It's dead. I'll take it to a repair center tomorrow, but i want to ask you: did you have success updating your 8400bt firmware? Do you know if there's a way to power up the unit and fix this issue? Quote Link to post Share on other sites

lockee Posted October 13, 2015 Report Share Posted October 13, 2015 Hello, I have the same issue now. Cannot power on after firmware upgrade. I also have not been able to find anyone in Australia that can repair it. Quote Link to post Share on other sites
