Bios updated to v7

Changelog:

>ASUS-Crosshair-V-Formula-Z-2201 MOD v7 (2018-11-25)<

I cannot flash my bios using any of the 4 .cap files you attached. I keep getting the same error message: Security verification failed. I went to the Asus website and updated to version 2201, downloaded your Ultimate version and placed on a freshly formatted USB drive. Went into EZ flash 2 Utility (v.01.04) and tried to flash using that file. Didn't work. I read somewhere that I had to use the white USB in the back and press and hold the ROG Connect button for 5 seconds, which seems to have done something as my computer resets when I do that and the link icon on that button lights up. The USB port even says ROG Connect on it. I know Windows 10 is installed on m.2 but I just can't boot to it. Bios doesn't recognize it.

What am I doing wrong?

@Tanisll - USB Flashback is what you need to use, you cannot flash mod BIOS via EZ Flash within the BIOS. White USB Port, you were doing it correct possibly, but maybe not waiting or maybe your USB stick is not compatible.

Smaller, cheaper USB is better and more compatible (256MB-2GB), sometimes larger 4-8GB or above have compatibility problems, same with USB 3 devices.

You should see light LED flash on your USB if it has LED, and light on board button will get faster as it nears the end, sometimes takes 2-5 minutes.
Make sure .cap BIOS file is in root of USB, not in an folder.

@Tanisll

Please, be also aware that no bios in the first post are updated anymore by the original thread owner. The last bios update is v7 and can be downloaded from post #152.

@Phoenix48 @Lost_N_BIOS I am trying to use a XPG SX8200 with a pci to mvne adapter on the Crosshair V Formula Z motherboard. I am trying to flash the bios using the flashback utility with the v7 driver and I cant get it to flash. I was wondering if you could help me out.

Will this XPG SSD drive work with the modded bios or am I wasting my time. Second, if the bios flash works, what should i see the name as in the BIOS main tab. And finally, is using a 32gb USB a waste of time ? Id hate to go out and buy a smaller one and get the same results.

Thanks for your hard work on this btw!

@Bigbadaboom

I don't see any reason why it would not work. Once it is detected, it should appear as something like "PATA disk". As for the 32 Gb USB, i am not sure if using your 32Gb USB is a waste of time. In fact, maybe it won't flash at all because Flashback don't always recognize a USB key higher than x Gb. x being a number between 2 to 8 that i don't know exactly and it may also, for all i know, depend on who manufactured the USB key. Lost_N_Bios mentioned this recognition problem with USB key that are too big for Flashback in the post # 154. So i suggest that you try to flash with a smaller USB key.

Even with that said, take the time to eliminate all other possibility first. As you said, it would be frustrating to buy a smaller one and don't get a better result. For example, make sure your USB key is formated in the right format (FAT32 is usually the best bet). Also be sure you insert it in the right USB port behind the PC. You may also make sure you press the flashback button long enough for Flash back to start and, after, let it run long enough to finish. I know some of those advice may sound elementary but most people forget at least one of those so i prefer to say them anyway and be sure.

You can try your 32GB USB, sometimes it's OK but not high chance of success. If no luck then try to find old cheap smaller ones around your house. If you purchase any new ones, get a few smallest cheapest ones you can find.
To add to the above, be sure you don't rename the BIOS file, and be sure to put the BIOS file on the root of the USB (Not in any folders)

Went out this morning and purchased the smallest drive i could find, its a Verbatim 8gb. Worked first time as described in the instructions. Thanks for everyone's help on this.

Great you found a working USB so you were able to flash!

Bios worked fantastic, 2 970 Evo's running, one is boot. Thank you, and thanks for any future updates/mods.

What is the bios listed as in rogcpuid?
Seems to have worked with an adata uv128/16g usb 3.1 stick, just want to check bios name

The name to use to flash it with flashback is C5FZ.CAP

Sorry i meant the actual bios name 2201...….. i guess version number, otherwise how can i tell its working, srry have to pick up the ssd tomorrow, Samsung 970 nvme.
Also i was wondering if any of the bios updates changed the way temp sensors work, more reliable maybe, because i got higher cpu temps after bios change.

@Wickedt - It's working if you flash it and reboot, then board still is running
I doubt he changed version #/Info, otherwise he'd probably mention that in OP
