[REQUEST] Lenovo Legion 5 (EFCNxxWW) BIOS Unlock
#1


-Manufacturer : Lenovo
-Model : Legion 5-17IMH05H (Legion 5i 17" i7-10750H/RTX2060) config: 81Y80007US
-Bios Revision : EFCN38WW
-Bios Type : Insyde
-Bios SLIC : ??
-Bios Link : https://download.lenovo.com/consumer/mobiles/efcn38ww.exe
-Rw-everything report. https://www.datafilehost.com/d/ac3c789b

-Extracted BIOS.fd from efcn38ww.exe: https://www.datafilehost.com/d/65570b98

hi, i would like to enable the advanced bios menu as well as anything else that could possibly be unlocked and im more than happy to make a donation for the assistance via paypal or other funding of your choosing. i've spent a good deal of time trying to accomplish this myself and initially i set out to unlock the undervolt functionality that is blocked on most/all 10th gen intel cpu's due to the plundervolt mitigation and i was able to by extracting bios > using UEFITool/Universal IFR Extractor to extract a list of settings and available values > then used RU.efi at boot to edit the appropriate bit in "CpuSetup" which was "0xDA" (OverClocking Lock) from "01" to "00" save/exit and undervolt is functional from xtu/throttlestop.

i've tried to repeat my steps to change things like `Setting: Maximum Memory Frequency, Variable: 0x144` for example to change it from the 2933mhz it's locked to now up to 3200mhz (pre-installed ram is 3200mhz but bios limited to 2933 on legion 5i models).
but i find it more difficult to find "0x144" (??) compared to finding "0xDA" (00DA) and so here i am asking for some help either by way of guidance on how to unlock the advanced bios menu or other suggestion. thanks for your time, help would be greatly appreciated.

Hi sorry for my english, i am using translation.
I've been in the hackintosh community for many years, but I couldn't achieve this on my device, I guess it's because SATA can't be set to AHCI...
And this setting is available in the BIOS>Advanced menu, but I couldn't open this setting even though I tried all the functions I saw on the internet, besides, my BIOS file is in .exe format and I really won't be able to mod it.
Any help would be appreciated.
thanks in advance
