good afternoon. Perhaps my question will sound incorrect because I use a translator.
I wanted to update the BIOS on my monoblock, prepared the USB media, and prepared the firmware itself.
The instructions said that you need to update with built-in tools, but I didn't have that.
Then I tried the button (win+ B). After that, a message was issued that the update will begin now. As a result, a black screen hangs and that's it.
Now I can't get my old BIOS back. What do i do?
