If you want unlocked BIOS, you have to follow my directions, otherwise we can't do it

By the way, at the moment I have your version of BIOS
and so I'm trying to understand your instructions

You cannot use BIOS I made for kiranfdo, you will loose all your board specific info (Serial, UUID, NVRAM, windows key and possibly MAC ID too)

Here, someone helped me re-format those instructions, so maybe easier for you to follow now (I edited some just now too, so specific to your ME FW)

Now I will download the original and try your instructions

See my edit above

If you flashed in that other users BIOS with FPT or AFU already, and you did not make FPT or AFU backup of your own BIOS first, then it's a mess now and flashing stock BIOS will not fix the things I mentioned above.

i can't load original BOIS
but the serial number in BIOS is written mine

Sorry, I don't know what you are trying to do there, but I did not suggest you use AFU for anything here (except I asked if you made an AFU backup, before you flashed the other users BIOS - If you flash in his BIOS)
Please do the FPT stuff I mentioned and I can unlock BIOS for you

Ohh, you mean in the spoiler, about flashing original BIOS? If yes, that means download the stock BIOS from Asus and flash it using the stock standard flash method that Asus directs you to use.

bios protection

Please see my edit above, about flashing stock BIOS, if you have not done that yet. And then, DO THIS FIRST!! Then redo the FPT stuff, delete previously created biosreg.bin file and make a new one, AFTER You flashed stock BIOS from Asus using Stock Asus BIOS update method

As for error 368, great you made it that far, this is expected error I wrote a guide for this, send me your new BIOSreg.bin file after you flash stock BIOS from asus and then make a new biosreg.bin file and I will give you further instructions.

@Lost_N_BIOS
all right?

@Lowapm - Here is guide to bypass error 368 - Start at step #6, I have done 1-5 for you below
[GUIDE] Grub Fix Intel FPT Error 280 or 368 - BIOS Lock Asus/Other Mod BIOS Flash

Rename .efi to >> Shell.efi

BIOS Lock Variable to change >> 0x8E5

So, at grub prompt, you will type the following and then hit enter, case sensitive
setup_var 0x8E5 0x00

Once done, reboot back to windows, then make NEW biosreg dump, using new name such as biosregnew.bin (Send me this)
Then try to write it back >> FPTw.exe -bios -f biosregnew.bin
Should be success now, then I will edit biosregnew.bin and unlock it for you

@Lost_N_BIOS
i off Secure boot

Yes, secure boot should have been turned off from the start, then do the grub stuff and then make new BIOS region dump and send to me

maybe there is an error, now upload a photo

Looks good, it's OK and yes that is error and not apply the change, but it was already set to 00 anyway. If we had to, we could set with RU tool instead, but looks OK to move forward now
So you should not have got error 368, maybe only caused by BIOS password set, TPM/Encryption enabled, or secure boot enable etc.

Please dump bios region again with new final name and send to me >> FPTw.exe -bios -d biosregnewF.bin
Please also before you send me this file confirm you can write it back without error >> FPTw.exe -bios -f biosregnewF.bin
