How to restore the embeded Linux OS after update failure

Hello everyone,
Today I installed the latest Linux OS updates via SSH and after a restart, the display on my Sovol SV07 remained completely dark.
Even the green and blue led on top are just constantly in the same speed blinking.
And after 20-30 minutes nothing had changed.

I have bricked my embedded Linux OS…

I have found an image on the Sovol Firmware page:

But inside is only an IMG file and a balenaEtcher.exe and no instructions.

So my question:
How to restore the factory OS image for the embedded Linux?

Thank you all for your upcoming help
