Tried an update from 3.0 to 3.4.20351 today (system, maps, all the bells and whistles).
Used a 32GB stick started the update; it all went fine for about 40 minutes and it crashed with some random orange screen and rebooted. It seemed to start again with formatting eMMC and it failed, reboot and now it is stuck at “Please Insert USB”.
I tried to stop the car, lock it, open doors, etc. however to no avail. Created a 2nd stick (different one) and tried it, still the same, I am stuck at “Please Insert USB”. Looks like the USBs are not working anymore.
I will try again in the morning, maybe removing the fuse for the head unit.
Any advice to recover, or I am in for a full head unit replacement since this one is toast?
