@SpaceLifeForm : a spare motherbord won't help just like that.
The actual encryption key is stored in a TPM chip (the rescue code is used to allow the system to access to the actual encryption key).
So even if you have a spare mobo, you'll have to transplant the TPM chip from the old to the new mobo.
The best advice: have a backup, as recent as possible. My backups are on VeraCrypt encrypted external (USB) HDD's.
That is why it worked. Have flux,, wiil move chip.
@SpaceLifeForm : okay, I watched the full vid...
I've done quite some hardware hacking in my life, but this guy is brilliant (and has all the right equuipment).
Thanks for sharing!
But my advice remains: make backups. If something truely gets messed up chances are that you're out of luck with a spare mobo.
He is an experienced GOAT.
He knows likely where the problem lies at startup just by watching the power meter.
