[Request] Unlocking Lenovo Legion 5i BIOS

@Lost_N_BIOS I’m going back to #5 trying to start over.

Lost myself somewhere along the way. This forum post is my personal Vietnam.

But as I was about to start over I noticed there is a new bios version out: https://pcsupport.lenovo.com/no/en/produ…nloads/DS544633

First I thought. Great! New Bios. That must be better, but then I read the change log:

Version EFCN39WW BIOS Notification:
Fixed: Fixed CPU max speed show error in SMBIOS type4.
Add: N/A
Modified: Disable GPU OC on Intel Platform.

“Disable GPU OC” sounds bad right? Should I avoid this version and rather start over extracting the EFCN38?
----------------------------

So I was finally able to extract the bios and find the OC lock. Turned out I had a corrupt software version or smf.

0xBC0C3 Setting: Overclocking Lock, Variable: 0xDA {05 91 9D 03 9E 03 7A 01 03 00 DA 00 10 10 00 01 00}
0xBC0D4 Option: Disabled, Value: 0x0 {09 07 04 00 00 00 00}
0xBC0DB Option: Enabled, Value: 0x1 {09 07 03 00 30 00 01}

Ok, I’ve managed to get all the way to booting into a usb stick with ru.efi renamed. But I’m struggeling to enter the cpusetup menu. (alt+= according to guides). Nothing happens when I press alt + (shift+0).

Do I need a different keyboard? Not sure what I can do.
