[REQUEST] Modify BIOS version of dumped image(Panasonic CF-RZ6)

[thslr2020]

Hello.

I keep tried unlocking FIVR lock(XTU, Throttlestop) to do undervolting, but failed. What I tired is...

1. Unlocked hidden menu >>> Disabled CFG lock, Overlock lock, SGX
2. Replaced CPU microcode to 2017, 2018 version (pre Spectre, Plundervolt)
3. Disabled Intel ME, Hyper-V & Vt-d
4. Removed microcode update of Windows(mcupdate_GenuineIntel.dll)
5. Try from fresh Win 8.1(boot with USB)

Even I already did all of above, XTU and Throttlestop is still locked. So I think what I can do is downgrade the BIOS version, but Panasonic does not provide the BIOS image file and gives only installer(I checked with 7z, but there was no perfect image file).

Is there any way to modify the BIOS version to spoof the installer for downgrade?

Here is my dump and version is showing as V2.00L30 in BIOS.

Solved by patching BIOS installer with IDA Free.
