Error 280: Failed to disable write protection for the BIOS space!
ok, i try to use
AMI IFR Extractor [Tool Guide] AMI Setup - IFR Extractor AMISetupWriter
or Using the AMI tool AFU t455f16-Guide-How-to-flash-a-modded-AMI-UEFI-BIOS.htm
Amm..
I tryed AFU, and seems to be it's done with original .CAP bios.
But i have no modifed bios (.ROM file) to try WRITE bios to flash with AFU.
Hmm.
Some guy writed about method with originals_modded bioses.
[Guide] How to flash a modded AMI UEFI BIOS (17)
Do you have some method to mod originals bioses? :)
Sleep mode is on :)
@ctacb - You might be able to use mod BIOS in EZ Flash, but we’ll have to test, low chance it will work. Other methods like the AI Suite method works sometimes too
Or you can try this method, download files in this guide, then pay attention only to last spoiler for flash method (Mainly this is flash stock BIOS first, then mod BIOS without a reboot, using the AFU in that guide)
https://linustechtips.com/main/topic/592…r-motherboards/
Similar/same method described here - [Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS (132)
Send me your biosreg.bin file and I will make simple edit so we can test and figure out working flash method before we try the actual fan edit changes.
Since you mentioned sleep, please try this. Put system to sleep (S3) for one minute, then wake it up and try the FPT flash again, sometimes this disables the block due to BIOS bug. If that works, then we can flash via FPT 
Thanks, please let me know about the sleep test I mentioned.
Then, before I send you anything modified to test, try this. Follow this guide, you can start at step 6, I’ve done 1-5 for you and the info is below
[GUIDE] Grub Fix Intel FPT Error 368 - BIOS Lock Asus/Other Mod BIOS Flash
Rename your .efi file to Shellx64.efi
You’ll be disabling both of these >>
SMI Lock, VarStoreInfo (VarOffset/VarName): 0x9D
BIOS Lock, VarStoreInfo (VarOffset/VarName): 0x9E
So at grub prompt you will type the following (separately)
setup_var 0x9D 0x0
setup_var 0x9E 0x0
Then reboot to windows and try to FPT flash the stock biosreg.bin file again.
If success, then flashing mod BIOS problem solved and I will work on Fan BIOS for you to test, if problem not solved, then I will send you mod BIOS later tonight to try and flash using the various methods we discussed above.
