“./UEFIPatch <ROM/CAP/Bios Image file for your motherboard> -o <patched bios file name, can be whatever you want>” can it work? I have no idea…
Lets start by downloading from “Release 0.28.0 · LongSoft/UEFITool · GitHub” [UEFIPatch_0.28.0_win32UEFIPatch.exe.zip] UEFIPatch_0.28.0_win32.zip file. It has 3 files in it.
UEFIPatch.exe
patches-misc.txt
patches.txt → This file will be replaced!
Finally the command input: ./UEFIPatch <ROM/CAP/Bios Image file for your motherboard> -o <patched bios file name, can be whatever you want>
--------------------------------- oooooooooooooooo -------------------------- BUT, I am not sure about, the patch file is only related with Hackintosh or not!
Then are the original UEFIPatch_0.28.0_win32.zip contents are enough for flashing the bios that we are looking for or not! Any ideas?
Patches.txt is downloadable from there, but it is related with Macs only!
Without the Patches.txt the UEFIPatch command makes modifications to the second file. I have tried the result, but Asus bios tool said: It is not a proper bios!

After having read your edited post I understand what you want to get investigated.
As soon as I have gotten several reports about successful flashes of modified BIOSes by using the tool UEFIPatch the start post will be updated (by me or by my successor). What we need are valuable results and not speculations.
I don’t want to be investigated. I want to be sure about the new flashing procedure. I can not ask new questions related with the topic at those forums, thread is closed for new replies.
Probably yes. Either it works or not, but your currently in-use will not get corrupted. Don’t forget to save an SPI Backup before trying to flash the modded BIOS.
I have a basic FPT flashing question. I’m 99% sure I’ve got a solid modded bios that’s ready to flash. My Intel ME version is 12, so I’ll be using the Flash Programming Tool under CSME System Tools v12 r38. My Dell has a physical service mode pin that will allow for an FPT flash.
Is it problematic or potentially problematic to simply flash over the current bios with the command FPTW64.exe -f bios.bin (and this assumes the modded bios is named bios.bin)?
Or, is it safer or required to erase the bios first, and then flash?
Type FPTW64 -REWRITE -F moddedbios.rom (for example) and press enter.
turn off your pc and reboot.
When I mis-flashed my bios, there’s no question that the replacement bios was broken. But I did simply overwrite with FPTW64.exe -f bios.bin, and am now considering proper FPT flashing to finish this off. Thanks
-REWRITE Rewrite the SPI with file data even if flash is identical.
fpt -h will get you the CMD switches
The rewrite switch usually is not needed but its useful to write if the system has the same bios version and ensure the block override, when for ex.: some tiny adjustments were made in previous flashed mod file and tool still complains about it, being identical data.
the hey the Flashrom v1.2 utilities link doesnt seem to work anymore, i was trying to help a friend get rid of a cyberpowerpc bios from his ASRock b450m, and for some reason the link either says that it doesnt have a app associated with it to open it and errors out, or for his pc it just turns into a notepad file. is there something im missing? (i’m a mega noob and usually solve issues via reddit and google)
As I just have tested >this< link is still working fine and doesn’t need an associated App to get the *.rar archive downloaded. Nevertheless you need an up-to-date unzip tool like 7-Zip (currently latest: v2408) or WinRAR (currently latest: v7.01) to get the compressed Flashrom Utilities extracted.
My old p8b75-v asus motherboard (.CAP Bios) don’t have USB Flashback features and i’m not buying pcie to nvme adapter before ensure bios is modable so i can’t use AMI AFU method.
AI Suite is not available for Windows 10 so i had to install Windows 8.1 and use it to flash and voila it worked
Use UEFITool load BiosOgirinal.CAP, search text “CSMCORE”, scroll down to the last entry before “Volume free space” and insert after NvmExpressDxe final save to file Modded.CAP
Open Ai Suite → Asus Update → Update BIOS from file → Choose BiosOgirinal.CAP → after it loaded don’t click next → Delete BiosOgirinal.CAP and rename Modded.Cap to BiosOgirinal.CAP → now you can click next and flash it

Thank you very much for your short guide about how to get a modded MSI BIOS properly flashed by using the Intel FPT tool.
To make it easier for the MSI mainboard users, your guide has been quoted by me within the first post of this thread.
I managed to successfully flash modified bios to ASRock x570 phantom gaming 4 using flashrom. Original board bios version was 2.20 ( notice that it’s before AGESA 1.2 update came ) and I flashed newest version with mod applied.
