P9X79 PRO - Unable to update bios from v.4502

[XtM]

Hi,

My motherboard is an ASUS P9X79 PRO. I'm trying to update my bios from current version 4502 to 4701.

Updating through flashback didn't work. I downloaded bios file v.4701, renamed it as P9X79PRO.CAP, turned the computer off, plugged the USB 2.0 FAT32 formatted, pressed the USB Bios flashback button for three seconds... It blinks six o seven times and then turns stable.

Updating the bios through the internet didn't work.

Updating the bios through a bios file tells me "image's model bios doesn't match with bios' rom installed".

Updating through Asus EZ Flash 2 utility tells me "security verification failed".

Any ideas?

Thank you very much!

What CPU you got?

Have you asked Asus?

Hi,

My CPU is an i7-4930K

I've made the same question to Asus, but I haven't got an answer yet.

Thank you for your help!

Best,
Manu

It seems to be saying that the bios won't fit in the ROM. Sounds like a hardware error. Maybe RMA the mobo. Wait till you here back though.

You checked whether you have ROM or CAP bios?

Since my bios version is 4502 and my motherboar's original CD has an P9X79PRO.CAP file I assume it's a CAP bios, but I really don't know. I haven't tried the cap converter, since I don't know.

Maybe Asus have some way of identifying the mobos
