Either use extracted bios_region or body extraction for mod working file, both serve the same purpose, the goal here is remove the CAP header of 2Kb, avoid breaking signature (MMtool).
This header must be restored for USB BfB ONLY, the resulting file (CAP) will NOT be useful in EZflash on bios setup, this is ALWAYS valid for working with body extraction or bios_region.
OR my link working ONLY with a bios_region file.
Thanks for the quick reply @MeatWar
I completely overlooked your link to UEFI tools githubā¦ So should I use the latest version which I can see youāre using in the screenshots above? Or should I stick to the older versions you list in that last screenshot?
OR my link working ONLY with a bios_region file.
Iām not sure what you mean by this?
Edit:
Screenshots: https://imgur.com/a/znoxhwH
1: Extract body from original bios.cap with UEFITool A71
2: Open MMTool 4.5.0 and load the *.rom file created in past step, and add NvmExpressDxe_5.ffs
3: Make sure the driver (NvmExpressDxe_5.ffs) got inserted before saving
4: Open UEFITool A71 again and extract bios region from the modded *.rom file made with MMTool in previous step
5: Open the original biosfile.cap with UEFITool V0.28.0 and add the modded bios region
6: Save as āM7G.CAPā
7: Load onto USB drive and insert to āROG Connectā USB port and press + hold āROG Connectā button for 3 seconds.
8: Diode doesnāt start to blink as described in the mobo manual, it just shines solid green, which (as far as I have googled myself to know) means ābios file not acceptedā. Correction: It does start to blink when I press the correct button, but only three times slowly, and then one time quick, then stops.
Iām using a Sandisk 32GB USB 3.0 pen formatted as FAT32.
What driver sirā¦???
Small USB disk as possible, even better a 2.0
Have you ever used the feature āAsus USB Bios Flash Backā???
EDIT: Hereās your mod, rename to use it correctly.

The NvmExpressDxe_5.ffs

I think so? Itās this right? At least thatās what Iām trying to do.
EDIT: Hereās your mod, rename to use it correctly.
Ty! Although, I would appreciate to make it on my own. I donāt know which version you have used here i.e. (I donāt want the beta).
But could you spot anything I did wrong in my screenshots/list?
Small USB disk as possible, even better a 2.0
Ohā¦ Hm. I think I might have one somewhere.
Edit:
I just realised that Iāve been pressing the Clr CMOS button, not the rog connect 
I tried again with my own modded bios, and now it blinks 3 times, and then turns off.
Youāre probably right that I need to try with a different usb drive.
Edit 2:
Just tried with the standard untouched bios update. Itās the exact same thing. So I guess the USB drive is to blame after all. Can you recommend something known to work? Itās the same bios version as is already installed though. I donāt know if that could cause problems?
Its a common issue know on Asus USB BFB, the USB disk, the format, the name or board has an issue.
PSU off, cold Reset (CMOS Battery off), a couple of minutes to drain, 1 DIMM only and try it again.
EDIT:
Then its mb hardware issue or USB disk.
Iāve searched all my electronics drawers, and I canāt find any other USB sticks unfortunately.
PSU off, cold Reset (CMOS Battery off), a couple of minutes to drain, 1 DIMM only and try it again.
Iām gonna try this tomorrow and report back.
Thank you so much for your help and quick responses

Just tried this again without luck. The button flashes 3-4 times slowly, then 1 time quickly and turns off.

This thread has not been designed for users, who have problems with Asusā USB BIOS FlashBack feature.
I would really appreciate if one of you could confirm, whether my method to re-encapsulate my *.bios file is correct or not though?

@MeatWar which bios revision did you use for this build? I noticed you had the latest ābetaā open in your screenshots. Iām not really that excited about installing that version, so just checking to be sure.
Optional mod flash using non-CAPSULE file, in this guide
Wellā¦ itās is the last and BETA, dont like it, do it yourself, thatās all from me, good luck.
donāt like it, do it yourself
Well thatās what Iām trying to, but Iāve tried to get a confirmation if Iām doing it right three times now, and you still havenāt answered? 
thatās all from me, good luck.
lol okayā¦
To be honest, if the guide told people āwhyā instead of just ādo thisā it would be a lot easier to understand.
Example: Why do you use two different versions of UEFITool? You still havenāt answered that either, despite it being asked earlier by other users. Really not making it less confusing.
Well if the mod was badly done, already was toldā¦, but your issue is flashing the modā¦
Seems your USB BFB function is out of order since you cant even falsh an Original Asus file, so it leaves the option linked using a non- CAp fileā¦what else dont you understand or whats wrong in the guides???
told people WHAT???
DIDNT YOU SAW the screenshot? CANT YOU FXXX read that the NE is used FOR EXTRACTION and the regular for swapp operations???
Do you know HOW MANY users did succedd using this guideā¦ I LOST COUNT and NEVER HAD IT, do you want me to SAY the issue hereā¦by using the correct words???
but your issue is flashing the mod
I forgot to say it worked with a different USB i found today. MB.
So now I just wanted to make sure my own mod was properly made before trying again, as I donāt want the beta bios.
DIDNT YOU SAW the screenshot? CANT YOU FXXX read that the NE is used FOR EXTRACTION and the regular for swapp operations???
First off, calm down mate. Thereās no need to get rude.
Incredibly childish behaviour, especially from a moderator.
What Iām asking here is, why two different revisions of the apparently same software, is needed? I think there might be a language barrier here, judging from your replies. Hope this makes better sense.
You know where you can put thatā¦SIR.
This is a forum that offers users shared work/help etcā¦complain some where else, understood???
