After reading this topic, I want to add a helpful and reliable link.
You cannot update the modified BIOS on some Asus motherboards.
On the screen, you will receive errors like:
“BIOS update failed!”
“Security verification failed.”
I think this will be a great help to users who have trouble installing modified BIOS on Asus UEFI motherboards and some other UEFI-supported motherboards.
I appreciate the efforts described here. But most users don’t want to deal with such details.
I recommend the BIOS Update Application I previously shared under the name "[Tool] New “UEFI BIOS MOD Tool” (multi-language).
Multi-Language Support Added to All BIOS MOD Update Tool Applications.
As you can see in the images below, Turkish, English, German, French, Spanish, and Italian language support has been added.
