XxDarkLightning Posted September 30, 2023 Report Share Posted September 30, 2023 So I have my W4400NEX on a bench with a power supply. Currently have power going to The constant and ignition rails and ground to ground. I successfully purchased a new SD card, loaded 1.00 on it and it booted just fine. Used a thumb drive to update to 1.01, then when attempting to update to 1.02 I got an update failed message mid update, I believe. Every single time a power up the unit, it immediately is attempting to update with the 0.00 -> 0.00. Whether there is a USB thumb drive present or not, it tries to update and fails with the 0.00 ->0.00. I tried a new SD card with 1.02 freshly on it, and it still goes right to trying to update with every boot. Anyone have any suggestions? Usually people are looping on a different screen than me and people with the 0.00 issue seem to try a different USB and it works. My USB worked for 1.01 update just fine so I figured it wasn't that. I tried another USB with 1.02 on it and it doesn't work to update. Quote Link to post Share on other sites
4500IlIll Posted October 22, 2023 Report Share Posted October 22, 2023 I have this same problem, were you able to fix it? Only thing I found to change the boot mode here: http://avic411.com/index.php?/topic/81469-avic-development-mod-device-backup/&do=findComment&comment=340158 Connect via serial cable and run command boot mode to chage it to 0 (normal) Currently is in boot mode recovery Quote Link to post Share on other sites
