@nimaim,

One thing good to know I was able to use the DOS Flash drive created with Rufus with a autoexec,bat command to automatically flash a good rom after black screen. This is a very convenient thing to have to avoid using the programmer especially if you change a setting in Bios that really doen't brick in our case changing SG to PEG boots to black screen. Just put in flash drive walk away and it auto flashes the good rom boots fine. Just make sure you have CSM enabled in Bios before doing anything else and the order of boot has flash set first which I believe it is automatically setup that way since I did not touch to boot order.

What I did:

edited autoexec.bat on flash drive added:

call auto.bat

in the auto.bat file just added one line

FPT.EXE -bios -f OPBIOSUM.bin
Make sure FPT.exe and fparts.ext are in the root of the flash drive. I am trying to figure out what I need to set path if its all in C:\FPT. I used set path but it still complained it could not find fparts.txt. Maybe I should have set path in original autoexec.bat and not auto.bat?

Need to add reboot when done so I don't have to sit there or watch a timer and guess when its done, is there a reboot switch for FPT, looking through the intel PDF I don't see one. How to setup a reboot command after it done flashing might be hard thing to do?

@pcfr33k - you can use second command for FPT, on next line after first >> FPT.exe -greset
@nimaim - it's OK, I need to get caught up on some posts here anyway, and I need to dig into that AFU exe and see if I can bypass the signature check too.

Will it complete the flash before executing the 2nd line of FPT, do I need some kind of delay or timer in autoexec before the second FTP command is executed?

That worked perfectly, thanks! I don't know why I did it but I preferred a second bat file to modify and leave the original one alone except for one modification added the \FPT to the path not even sure if I needed that since I have cd in the auto.bat

contents of autoexec.bat

@echo off
set PATH=.;\;\LOCALE;\FPT
call auto.bat

auto.bat contents

CD C:\FPT
FPT.EXE -bios -f OPBIOSUM.BIN
FPT.EXE -greset

I assume flash will complete then next command line will run. If that doesn't work, make a second batch file and call that at end of first FPT command batch file.
Wait, so you got it, and it works now? Great if so!

Thank you for your effort. Now I need your help.
I successfully flash the BIOS and play with it for some hours. However, When I play with the Windows-Push Button Reset option in the Save and Exit (I'm not sure if this option will save the changes,maybe some changes are wrong). It seems boot to the windows recovery. However it stuck at windows boot, shows waiting and the circle runs. I force close the computer and restart it. But then show nothing on the screen, the screen remian black while the keyboard backlight and fan works.
I try to clear cmos by unplug adapter, battery and cmos battery for 1 minutes. But it still shows black on the screen. I think I need programmer to flash the bios. But I did't make bios full backup. I only have the fpt dump.
Could you please share the full rom of flash, or if I can merge full rom of flash by someway?
Thank you very much.

@brz - I don't know anything about the "Push Button Reset" and actually asked @niamaim what was inside that (If it was submenu or setting). I'm not surprised it doesn't work.
But I can tell you it doesn't have anything to do with saving BIOS changes, it's simply a power reset feature. As for what happened when you tried, it could be unrelated glitch, or could happen any time someone uses that, we need more testing by someone else to confirm.
If it always causes this, we'll have to hide the setting.

Still waiting on @nimaim to send me a full programmer dump, once he does I can make new complete BIOS for you to use with your dumped BIOS region. Please upload your FPT backup, and once I have a full dump for this model I can make you new complete BIOS
In meantime, do the CMOS Clear longer with all power/batteries removed, try 10 minutes and at end of 10 minutes press and hold the power on button for 1 minute before you put it all back together to try and start. If still fails, remove one memory stick and try again (Sometimes this resets things)

It seems no luck with CMOS clear. I do as what you say and screen remains black. Original I have 2 memory stick. No matter I remove either one or remove all memory. The phenomenon are the same.

The push button reset entered into windows boot without reboot.(Seems windows recovery boot with a circle and "waiting", The stuck on it may because my windows install). I'm not sure if this reset will also preform an bios reset or something else. What's more, Does the unlocked bios has correct default value for unlocked setting?
PS: I flash the unlock bios directly with fptw64 in windows, but I think may not related. (I verify the bios are the same by dump the bios again after flash)

I will read current full bios flash soon. And there are two chip look like flash on motherboard. One is near PCH 25q128jvsq, I think this is 16MB main flash. Another is near memory, labeled HH1802 25Q20, I'm not sure if this is another flash store EC or NVRAM or something else.

@bzv - OK, then probably bricked, just wait for me to get dump and I'll get that fixed for you. Then, we need someone to confirm this setting always does that, or you can re-test if you want, once you see you can recover with file I send. If it does always do we'll have to hide it from user.

I assumed from the setting name, it meant "Reboot" like you pushed the windows power restart button in start menu (start, reboot/restart)

the mod BIOS has all defaults, only made menu's visible. However, for now this BIOS should only be created by user sending me their BIOS dump via programmer or FPT BIOS region dump, then I edit, then you put back same way you backed up. Otherwise you loose board details because of flashing stock BIOS via FPT.

Other is EC, no need to dump that. If you want to dump your entire BIOS via programmer and send to me, I can fix it for you with the mod BIOS region again, or you can also add in any previous backups you made (Those I can re-edit properly with the mods so you keep your board details)

I successfully recover the BIOS by a programmer
The BIOS data in the flash chip is start from 0X60000H to the end of flash. I just replace it with my backup BIOS then it can boot.
This is mechrevo Z2's backup BIOS: https://transfer.sh/gLTWX/backup.bin
This is full flash dump by programmer which cannot boot: https://transfer.sh/JFb6d/full.bin
This is full flash dump by programmer which is recovered and update again to modded bios with new microcode: https://transfer.sh/SUUIT/fullmodded.bin
The windows push reset button will boot the computer to windows advanced boot screen. If you choose restart of enter to windows, nothing will happened. But if you force close computer while boot into that screen(shows waiting and circle runs) It cannot boot forever. I don't know why. There's some difference in full.bin and fullmodded.bin, some of it maybe my changed setting, I'm not sure.
What's more, If I flash the modded BIOS, my UUID would become 000020000300004....00009, and SN will be "Standard"
If you are available, could you please also modify mechrevo Z2's backup BIOS, thank you.

The modded bios seems has something wrong with force close. My windows has a bluescreen and I force close it. After that it remains black on boot. Clear CMOS have no use for this problem.
Same method of clear CMOS can reset the change of overlock setting and can boot.

@nimaim Could you please also test if the BIOS has problem with force close? The way is to use push button reset option, and while windows boot and the circle runs, force close it. If it fail to boot, make a backup of bad bios full rom and upload it. And it need to reflash the good full rom by programmer to fix.

@bzv - good you got it recovered! Yes, I need to put warning on the download mod package, or remove it for now, due to FPT overwriting serial etc.
Mod needs to be done on individual basis, and I need to switch out the BIOS download for individual modules with images showing user how to modify into their FPT dump instead, then reflash
We're working behind the scenes on getting AFU to flash mod BIOS, but no luck yet. I will repackage the mod for you and everyone tonight, so it can be used in a way that wont loose your serial, UUID etc.
This will require some modification on user end, dump BIOS region via FPT, and then replace 3 modules via UEFITool, then reflash BIOS region via FPT. I will try to make this explained in detail and with good enough images so it will be easy for everyone to understand.

I think mechrevo BIOS is not same as this one, they all are a little different. I'll need to make a separate package for that one too.
And to alleviate this issue you're having now I will hide that setting in all BIOS, no need for that anyway, sounds like a debug option, if user needs to get to that area they can push F8 at windows boot.

@pcfr33k
The problem happens at when you choose that button and when the windows recovery is booting(thr circle running), long press the power button to force close it. Can you give a try?
@Lost_N_BIOS
For the serial problem, when FPTW flashing the modded bios, it shows some part, I think one of the part store the SN, Maybe can bypass one part in FPTW?
For the issue of black screen, I think it may not related to that option, but related to force close. When I have a bluescreen and I force close it. It also appears the problem. Only hide the option may not solve the problem.
The dump of bios seems different even if I normally reboot, I don't know which different cause the problem. If you need, I can have full dump to help you debug.
