2020.48.37.8 Needed firmware -URGENT


What does „Tesla not able to read SeC“ mean?
Did you try to force a software download via service menu?

Tesla vehicle not able to reach Service center. It is in montenegro,

It is blackscreen

I had a similar issue a while ago. I was able to recover it by pressing and holding the two roll buttons and the two above them at the same time on the steering wheel plus the break pedal.
I was not lucky with the first and second trial, but after the third one, after a minute or two the tesla logo appears again and the software came up…

Good luck,
