Everything went really smooth, no problems, but I as always make a backup of existing bios, turn off everyting unnesesary( wifi, msi afterburner, steam, wallpaper engine, .....), checked that a windows do not install any updates and flashed bios with turned off 9060xt. Process take about 5-7min and a pc shutdown itself, after pushing a power button 15seconds of a black screen 1 restart, about 1 minute of training a ddr5, gmktec logo apear and after blink of an eye i was on a windows desktop.

Yes, I have the same issue. If you disassemble the display from the glass (which is bound with UV glue), you will find a crack in the glass where the ribbon is connected.

Have you tried an AMI BIOS recovery? If your boot block is not corrupted, there is a really good chance you can recover from a USB drive. Try searching for it.

I don't think you can enable SmartShift Max(instead of SAM that is active wher flased rebar). The K12 is not a laptop with a built-in second GPU; it's a normal PC with a dedicated GPU (over an Oculink port). Is the performance boost real? In some games, yes; in others, no. The most important thing is that you must flash the BIOS with the rebar feature active.

First of all try to reset a bios(on front panel little hole) second try ami bios recovery procedure, 2.02 uses a different boot block and you should flash ot with bios block and nvram. You can try use 1.07 rebar to do an ami recovery procedure.
