Just to add s.th. about USB Sticks. About many users using higher capacity USb flash drives on later dates of times, as of today, there quite many USB flash drives offered e.g. with minimum 32GB at quite low costs.
I had issue with e.g. Asrock Instant flash (Asrock Z77 Pro4, even with UEFI), that it didn't detect my 32GB USB flash drive, (even when freshly zeroed Partiton table, and freshly partitioned, formatted with FAT32 or FAT16 etc),. Also taken one Primary Partition from start sector 2048, as the other drive has, that was detected by Instant flash very well.

The workaround was, for also to make the 32GB USB flash drive work, was to create a Primary Partition not using whole USB pen drive (e.g. 32GB),
so to create smaller partiton only (16GB). After that Asrock Instant Flash also detected the 32GB USB-stick by using a smaller partition (16GB).

Maybe this applies here too, as many flash drives today have often higher capacities, which can make problems with certain programs, not alaways programmed so good.

Hi friend.
I cannot unlock Lenovo V130-15IKB bios for flash. tell me how to make changes (change "bios lock"). Address 0x17 is not real.

1) fptw -d b.rom -bios = OK
2) fptw -f b.rom -bios = error: Error 368: Failed to disable write protection for the BIOS space. FPT Operation Failed.
3) uefitool 0.27 search "bios lock" and "extract as is" "1.sct"
4) uefitool NE_A51 extract as is "Section_PE32_image_E6A7A1CE-5881-4B49-80BE-69C91811685C_Setup.sct"
5) run two copy Universal IFR Extractor7.exe and extract files (1 IFR.txt and Section_PE32_image_E6A7A1CE-5881-4B49-80BE-69C91811685C_Setup IFR.txt)
6) bios lock search result in "1 IFR.txt" :

boot from uefi usb flash: enter (for check) setup_var 0x17 - result : 0x00

But it should be 0x01. And address 0x17 looks unreal. what to change? how to do? help me please

0x17 - unreal address

Bios dump (via fptw) and ifr text file attached.
help me please

I want to report to anyone who will be interested that after reading similar situations on the forum, I found these variables (bios lock) in the "pchsetup" area.

Also I see there are similar variables that are in other areas for example: bios guard in area "cpusetup", me fw Image re-flash in area "mesetup".
I just ask you to tell me how to understand which variable is related to which area after unpacking the ifr extractor?

can I use this method for dell's laptop bios ?

@alllus - BIOS Lock variable is never same in all BIOS, you have to check what the variable is for your own system
As for Insyde BIOS, this is best done by dumping vars (NVRAM) with H2OUVE, edit, then flash back. Sometimes this does not work and you need flash programmer, maybe 10-20% of the time
Make a thread for your specific board and will help you do all this. From what you show above, I did not check personally, but it does look like 0x17 is your correct BIOS Lock variable (Yes, that is correct, and real, if that is your IFR output above)
For Insyde you may also need to check SMI lock, or FPRR. BIOS lock already 00, means nothing to do there, this is not the cause of 368.
Sometimes, BIOS Lock, or SMI lock, or FPRR is set within a module, not BIOS settings/NVRAM, and in those cases is where you would be forced to use flash programmer like CH341A

ONce you make a thread, please link stock BIOS download page (not the BIOS), and give full model of system there too.
Then, also tell me what it is you are trying to do, and show me output of this command >> FPTw.exe -i

BIOS Guard is not related to anything here

@cuongvfc - Some yes, some no, all depends on the BIOS type

how do I know what's my bios type? can you show me how to check that ?

@cuongvfc - You can show me image of the BIOS, or link me to the BIOS Download page (Not direct BIOS Link), and I will tell you.
Many Dell (not Alienware) BIOS, there is not much to edit/reveal, what are you wanting to do?

This error happend when i was flashing my asus modded bios. Help me please.
Error 201: [FPTw64.exe] cannot be run on the current platform.
My board is p8z77vlx, modded bios from a backup one.

@sonbd2

I already saw ur other posts... this command is to run in a CMD Admin window, when running the command, the path given to the command and the place of the files must be the same.

Ex: C:\FPT (files r here), then the the command must be C:\FPT\FPTw64.exe (options next)

FPT.exe for 32bit OS and FPTw64.exe for 64bits OS, u cant run 64bits apps in a 32bits OS.

Usually a user that doesnt know this easy steps... is a user in great risk of breaking the systems when playing with bios mod files...

The tool Intel FPT can be very dangerous and powerfull for such users, ur warned.

I did like: press Shift + right click in the folder to open elevated command, so i think it's hard to be wrong path.

@sonbd2
There is an Asus Suite 2 trick flashing method for your board. If the method does not work correctly, this post may help.

Hello,

Please, help me with p. 3

3. Open Universal IFR Extractor and browse to the module you extracted above. "Protocol" will show Green UEFI, this means IFR can be extracted from this module.
Wait a few seconds, then hit extract and save txt file with similar name so you know what module you obtained the IFR from, usually this will be auto-named for you but not always.

I have got red text "protocol unknown". How to find exact what must export "as is" under UEFItool by PE32 / guid? I dont understand. I tried by guid from example, but it is incorrect as I understood.

I trying got vars for unlocking but still unsuccesful :(

My backup of main bios in attach and full bios dump also.
