Hi everyone,
Today I was updating to version 1988. I uploaded the files to the USB stick, started the upgrade process, and it got stuck and has been stuck in the boot process ever since.

Does anyone know how I can restore it?

Nothing to do, as soon as I start the car or connect the battery cable this screen immediately appears without giving any option to install or choose a boot disk.

In the first link there are 2 files in the bottom tha say recov.
Use one or another and do what is inthe manual. Use 2 pen drives, 1 for recov and other to the firmware.
