I did these steps and even went back to 1.6.1 on my Dell G7 7588 where I know you can undevolt, but it is still locked in XTU. Any help?

Do you think this will work with this G5 firmware? I get an error message and it looks like the header structure has changed.

HI guys, I think we can use this tool to modify a bios (Actually bypass bios lock).

Can you make a single convert option? Like this

[1 -- 1 System BIOS with BIOS Guard v1.10.0.bin] =>(convert to) [entries/System BIOS with BIOS Guard-1.10.0.bin]

Thanks for your work on restoring older BIOS versions for Dell laptops.

I have an older Inspiron 7000 gaming (7567) and was just wanting feedback from anyone who has successfully completed these steps on this model and if they ran into any issues? I'm looking to revert from version 1.12.1 down to 1.11.0.

I'm trying to use this on Dell Optiplex 3080 BIOS and this is what I get:

I'm unable to follow the rest of the instructions, because there are a few BIN files that show gibberish names....

Awesome work on this project, first off.

Am trying to downgrade the 9520 to 1.6.0 from here: https://www.dell.com/support/home/en-uk/drivers/driversdetails?driverid=4m14y&oscode=w2021&productcode=xps-15-9520-laptop

PFS Extractor successfully works, but Assembler says unknown header numbers et. Likely just a minor fix (imho)

PLease, is it possible to do this? If so then please do. I want to upgrade my bios to the latest version for all security fixes but do not want to lose undervolting . I can successfully modify my bios for undervolting but I end up with .bin files which I cannot flash anyway. On my laptop (dell inspiron 7567), i have to short the audio chip pins to enter into service mode to be able to flash these modified .bin files but the chip is extremely small and it is not possible for me to short the needed pins on my own without frying the chip (lol). Kindly provide the feature to assemble the modified bios entries.
One thing I noticed is that, the bios entries that your tool extracts are not editable whereas the entries extracted by the original PFS tool are editable by UEFITOOL, why is that?

Wondering whether you could also help in how to reflash LoM firmware?

I've a somewhat crippled Latitude E7250. After BIOS update from A16->A17 - which contains update LoM firmware it has corrupted NVM.

Perhaps you could help out in giving some pointers how to re-flash/hard reset NVM for LoM?
