I owe you a nice Pizza, man, that worked like a charm on a 2018 ASUS flip.
However there is a trick for non-QWERTY keyboards: ENTER THE GIVEN CODE WITH A QWERTY LAYOUT ( A = Q etc )
Also, use caps-lock to enter the code.
- 2017? -> use 2007 code
Additionally you can use Dogbert's python script to generate your code, not only for asus but for almost every brand out there: https://dogber1.blogspot.com/2009/05/table-of-reverse-engineered-bios.html
Thanks again, You and "our" internet
