Im trying to mod bios on Asus Z87-a but unfortunately with no effect. Is there any other way to "/gan" working ?

@CodeRush

I have an error "Secure Flash Rom verify failed" or "Security verification failed" error with /p /b /k.
Then I tried with /gan key. It succeed. But modifications weren't applied.

Any ideas to flash modded bios? Except using SPI programmer.

Thanks!

Mobo: Asus P8Z77-V LK

/GAN doesn't work anymore and this guide should be removed. SPI programmer is the best option here.

@CodeRush
I used AFU 3.6.01 which has /gan support.

I don't have enough background for SPI programmer.
So I don't have any options left but to buy new mobo?

The main problems comes with new mobo is they have different sockets. Thus after buying new mobo I'd need to but new CPU, etc =(

You don't need a new mobo, you need a cheap CH341A-based SPI programmer. If you have enough background to use AFU and read this forum, you'll be fine with it.
Here's a guide: [Guide] Using CH341A-based programmer to flash SPI EEPROM

@CodeRush

I don't think I need it =)
Just broke my mobo. Reverted to old bios -> modded it and ran /gan. After this monitor doesn't seem to be working. And no respond from keyboard or mouse (lights)

Hehe =)

Still need one, because now your BIOS is bricked and you want to restore it somehow, which can be easily done with SPI programmer. ;)

can this method on this link https://www.youtube.com/watch?v=Hk74-2xA7tI&t=34s be good for fleshing up the modified bios that I would use to insert the nvme module NvmExpressDxe 3.ffs into the original bios in ez flash mode it can not, because when loading a modified bios file, it evokes me error securiti verification failed or there is another way to flush bios my board is asus h81m-r

@boketa979
why not just use NvmExpressDXE_2.ffs
As stated previously, you cannot use EZ-Flash. If you're luck and have a Flashback port, you could do that.
AFUDOS Version 3.06.01 seems to have /GAN switch function as stated earlier.
I believe the /GAN function no longer works on the newer boards regardless of using the 3.06.01 version.

Has there been any progress on the preferred method to flash BIOS in non-flashback ASUS system?

please help to flash moded bios on asus Z170-A

So how can we succeed in flicking a modified bios, say, on my h81m-r whether it's an older or a new board I have a mod bios and afudos on usb contact, and now after your answers, I'm afraid to flush with 3.06.01 so I would not accidentally it destroyed the bios, although the cold rush wrote about some kind of backup, but I do not understand what it was that wanted to do, and if it was possible to protect some kind of bios if it was not to blush with afudos

and a little before I tried to flush my asus h81m-r panel and typing afudos mod bios. / GAN and throwing out the text unknown comand and it remains MAIN QUESTION how to succeed on asus plates insert flashing modified bios to support nvme ssd is not a problem to make such a bios already HOW TO FLASH it Tell us whether there is a solution and which is either to stop tilting more and throw asus plates and turn to newer or gigabytes or msi

hi guys I have a MAXIMUS VIII HERO Z170 can you tell me which version of afudos works? I tried using the 3.07 to backup the bios and tells me to switch to APTIO V
