@johnson2008 - Then no need to use EFI Shell FPT, go back to windows as we were, that was only test to see if there was some windows issue with FPT (Which there was not, this was due to your password set, possibly others stuff too)
Not sure what you mean by this >> H2OUVE.exe doesn’t find EFI version
Please go back to windows, after you disable secure boot, remove BIOS password, disable TPM/Encryption if enabled, and then make new vars dump with 100.00.16.08 again and send to me.
Once I edit the vars, you flash it back, then reboot and from windows with FPT (not x64) make a new BIOS region dump with new name, and send me that.
@Lost_N_BIOS
Thanks.
disable secure boot, remove BIOS password,disable fast boot with 100.00.16.08 again dump vars
vars-nopass-nosecure_16_08.txt (256 KB)
@johnson2008 - Program this back, then make new BIOS region dump and make sure to not mix up with any others (toss all others, not needed anyway)
Hopefully this resolves the issue! If not, you will need flash programmer
All unlocked there already, please make new BIOS region dump and send to me to edit 
BTW - Fast boot unrelated/not an issue here.
@johnson2008 - http://s000.tinyupload.com/index.php?fil…594382274551788
Flash it back via >> FPTw.exe -bios -f filename.bin
@Lost_N_BIOS
1.FPTw.exe -bios -f filename.bin still 167 error. Maybe i need flash programmer.
2.Try again modVar.txt：
after disable secure boot, remove BIOS password.
Execute the program "H2OUVE.exe -gv var.txt" and then Exec "H2OUVE.exe -sv var.txt" (the same just dump var.txt )
show [052] ""MemoryOverwriteRequestControlLock"" Format Error !
but Execute "H2OUVE.exe -sv varM.txt (original unlock varM)" is OK.

If you flash back in ANY vars I’ve sent you before, password and previous BIOS settings you just changed will be put back, so don’t do that!
Now you need to redo all again. Slow down, stop doing things no one said to do, or you’re going to brick the system.
Yes, it’s possible you need flash programmer, sometimes this is the case, and it’s looking that way here, sorry 
If you need links to the items needed let me know and I will link you to some examples (you need CH341A + SCOI8 test clip with cable)
@Lost_N_BIOS
Thank you very much
The flash programmer is difficult to operate ，I will go to Google to learn about it。
Thanks for you help again .
@johnson2008 - You’re welcome, sorry it’s being such a hassle!
So you have programmer already? It’s easy

@xu17913 - Answered you in your model specific thread.
@tonyG3 - Here you go - http://s000.tinyupload.com/index.php?fil…652506353439713
*** WARNING - To ANYONE with laptop and unlocked BIOS!!!
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don’t try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)
WARNING *** - This BIOS is user specific! If you are not user tonyG3 at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not tonyG3, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!
@johnson2008 - For MX25L12873F use CH341A v1.31(1.4) (CH341AFree) (This is the name of the folder), ASProgrammer 1.4 or 1.41, or CH341A v1.1.1.32

No, you need to dump current BIOS with programmer and send to me, then I edit, then you program back. Be sure all the things are disabled as we did previously, before you dump with programmer.
@heyheywill - What is your model, and what BIOS version are you using?
@Lost_N_BIOS thanks man, i missed the true ME FW Version it "v12.0.0.1069" not "v12.0.0.1067"
is there a problem or just flashing?
@tonyG3 - ME version does not matter for this, only for you to know which ME system tools package to get and for that only Major Version matters (V11, V12 etc)
You’re good to go, flash away
@heyheywill - Here is unlocked vars, flash it back using this command from same version that created it (100.00.16.08) >> H2OUVE.exe -sv varsM.txt
http://s000.tinyupload.com/index.php?fil…959386916767578
Then, do step #1 from below and send me your biosreg.bin
If you have already modified the BIOS in ANY way, you will need to re-flash it back to factory defaults using factory method (NOT FPT)!!!
Additionally, please remove all BIOS passwords, disable secure boot, and disable TPM or Encryption if you have enabled. Do this before moving on to below
If you do not have Intel ME drivers installed, install them now from your system driver download page, then start over here after reboot.
Check your BIOS’ main page and see if ME FW version is shown. If not then > DOWNLOAD HWINFO64 HERE <
Once HWINFO is open, look at the large window on the left side, expand motherboard, and find the ME area.
Inside that section is the ME Firmware version. Take note of the version. (ie. write it down or get a screenshot)
Once you have that, go to the thread linked below, and in the section “C.2” find and download the matching ME System Tools Package for your system.
(ie if ME FW version = 10.x get V10 package, if 9.0-9.1 get V9.1 package, if 9.5 or above get V9.5 package etc)
> DOWNLOAD " ME System Tools " packages HERE <
Once downloaded, inside you will find Flash Programming Tool folder, and then inside that a Windows or Win/Win32 folder (NOT x64).
Highlight that Win/Win32 folder, then hold shift and press right click. Choose “open command window here” (Not power shell! >> * See Registry file below *).
If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.
((If “open command window here” does not appear, look for the “Simple Registry Edit” below…))
Step #1
Now you should be at the command prompt.
You are going to BACKUP the factory un-modified firmware, so type the following command:
Command: " FPTw.exe -bios -d biosreg.bin "
>> Attach the saved "biosreg.bin ", placed into a compressed ZIP/RAR file, to your next post!!! <<
Step #2
Right after you do that, try to write back the BIOS Region dump and see if you get any error(s).
Command: " FPTw.exe -bios -f biosreg.bin "
^^ This step is important! Don’t forget! ^^
If you get an error, reply to this post with a screenshot of it, OR write down the EXACT command entered and the EXACT error given.
Here is a SIMPLE REGISTRY EDIT that adds “Open command window here as Administrator” to the right click menu, instead of Power Shell
Double-click downloaded file to install. Reboot after install may be required
> CLICK HERE TO DOWNLOAD CMD PROMPT REGISTRY ENTRY <
If the windows method above does NOT work for you…
Then you may have to copy all contents from the Flash Programming Tool \ DOS folder to the root of a Bootable USB disk and do the dump from DOS
( DOS command: " FPT.exe -bios -d biosreg.bin " )
