Hi12 won't turn on

I bought the device 3 years ago, great stuff, worked like a charm!
For a while, I haven’t touched the device and when I finally did- the windows was all messed up, so I decided to reinstall everything.
I think I installed the wrong BIOS or made a mistake along the way because the device won’t react to anything now. I won’t turn on, it won’t show any light- nothing works :frowning:
What can I do? Or is it a goner?

Thank you :slight_smile:
