@luki508 - For your mod BIOS, did you try flashing from within the BIOS with BIOS on USB, but mod BIOS renamed to exact name as the stock BIOS including extension too?

If yes, and no luck still, please check your BIOS Main page and see if you can find ME FW version, if not download HWINFO64 and check with it on large window, on left expand motherboard section then go to ME and find ME firmware version.
Then download matching Intel ME System Tools package from this thread in section "C" Inside you will find Flash Programming Tools folder, and inside that a windows or Win/Win32 folder.
Select the "Win or Win32 etc" folder, hold shift and press right click, choose open command window here, then enter the following command and zip and attach the output file

FPTw.exe -bios -d biosreg.bin

On a copy of this file, you do your modifications that you want flashed. You don't need to send me that modified, just the stock output is fine, but this is the file you need to redo your mods on again, then we will reflash it once I tell you how to unlock BIOS lock

Intel Management Engine: Drivers, Firmware & System Tools
i think you mean this thread,
i have
Intel ME Version: 11.8, Build 3425, Hot Fix 50
Intel ME Recovery Image Version: 11.8, Build 3425, Hot Fix 50
Intel ME FITC Version: 11.0, Build 1173
but in this threat there isn`t a version for Build 11 or do you mean this?:
Intel CSME System Tools v11 r20 - (2019-01-23)

Thank you

@luki508 - Sorry, yes, I forgot to add link to that thread! Did you try renaming mod BIOS to exact name of stock BIOS including extension and no luck flashing from within BIOS?

If not, then we'll have to do FPT way. Yes, download V11 ME System Tools Package, then run the command I gave you above, upload the created file for me to look at, and then wait I'll send back to you with a setting unlocked, then you will do your mod again on the file I send you back.
Then I will help you unlock the setting I unlocked in your dump, but on your current BIOS, so you can then reflash the final re-modified biosreg.bin dump we both edit.

so this is my output file ( it`s in a zip, because bin files aren`t allowed), is there a tool with i can modify this biosreg.bin file?
i only tried to flash the file generated AMIBCP, but this file is .rom file and if i flash it within the bios it says wrong file format.
thank you for your help


**edit**
can i use amibcp to mod also .bin files?

if i try to rename the biosreg.bin to the original name E1782IMS.122 the bios says warning, wrong image format

@luki508 - biosreg.bin? I thought you modified the stock BIOS and was trying to flash that, not biosreg.bin? You're confusing things I said together that shouldn't be mixed up, please re-read carefully everything I mentioned.

biosreg.bin and FPT have nothing to do with renaming your originally modified BIOS file. I mentioned renaming, as in your main issue was you couldn't flash your modified BIOS file, before I mentioned anything about FPT or biosreg.bin.
And I said to wait to flash anything with FPT until I checked it, because of what you need to do below. Please slow down, be VERY careful with FPT, you will brick your board instantly if used improperly!
It's very likely half or all the changes you made in AMIBCP wont apply anyway, so there is no rush

What I said first was, your originally modified BIOS, I assumed was the stock BIOS you modified with AMIBCP.... Correct? If yes, rename that to stock name and flash via USB within the BIOS.
If that does not work, which it usually does, stop there, none of this statement applies to anything else, and none of the FPT stuff applies to this file anymore either.

bin/rom = same/same rename anytime to either one, as desired or needed.

biosreg.bin, from FPT backup you made, posted in post #5. That you can now modify with AMIBCP, this file you cannot flash with BIOS built in flash tool, only FPT, and that can only be done after you do the following to disable "BIOS Lock"
Follow this guide, starting at step #6, you can skip steps #1-5 because I will give your variable below - [GUIDE] Grub Fix Intel FPT Error 368 - BIOS Lock Asus/Other Mod BIOS Flash

BIOS Lock variable >> 0x5AE
Rename your .efi file to >> Shell.efi

So at grub prompt you will type the following >> setup_var 0x5AE 0x0

Then reboot, and you can now flash your modified biosreg.bin file using FPT and this command (stop if you see any error, show me an image) >> FPTw.exe -bios -f modbiosreg.bin
change name of "modbiosreg.bin" in the command above to whatever you named your modified biosreg.bin file, or name it as you see above.

I can't boot into efi shell.. The option isn't in my bios

Ok got into efi with your post about how to boot into grub without efi setting in bios.. But now in grub i get this message:



Forgot what i said.. I now finally flashed the new bios.. But no new settings appear in my bios..

Ok sry for to many posts.. I now finally made it.. The new bios settings appear!
thank you so much

Can i deactivate the bios lock permanently?

And can i lock the cpu on all cores to 3.6 ghz?

@luki508 - Please edit your post to add new info, thanks

You should be able boot to Shell.efi I got that out of your BIOS exit page "Launch EFI Shell from filesystem device" But, maybe it's hidden from you too?

BIOS Lock can be disabled in BIOS settings, just make that section visible to you. It's disabled now since you disabled it, but any time you reflash stock or mod BIOS, you need to disable it again first before you reflash.
That can be done by editing the setup module via IFR/Hex, or within AMIBCP. In AMIBCP, it's in the hidden advanced section at >> Advanced >> PCH-IO Configuration >> BIOS Security Configuration

Yes, you can set default 3.6 at OC >> Adjust CPU Ratio, and per core settings are at hidden advanced >> CPU Config

yeah but my cpu 6700hq can´t push all cores to 3.6 ghz

You can only set as much as Intel spec allow you to set then, sorry for any confusion I didn't check CPU and only replied about what you asked.

Do you want me to unlock your BIOS for you? If yes, please zip up a package of one single image of each main BIOS pages so I can see what all you see on stock BIOS, just main pages no submenus or deep in settings (Main, Advanced, Chipset, OC, Security, Boot, Save and exit etc)

What didn't unlock for you in your AMIBCP mod that you still want enabled? not much in there, except in advanced menu. Also, put your mod BIOS in the images zip, so I can see what you did in AMIBCP for the settings you want, that didn't work

i already unlocked most of the extra options, but i have not recived any extra performance out of it

@luki508 - What did you enable with AMIBCP, that didn't show up in BIOS though? Chipset is empty, nothing to enable there

i enabled all oc options and all chipset options, all show up. i haven't unlocked cache options because idk how to work with it
