Yes. @Lost_N_Bios has left us with much knowledge. Hopefully we can apply here and make a modded bios 
Yes, Lost_N_Bios good thief:) He can understand the program code he stole:) At least I appreciate it, because other scammers (Big Modder 
) can bit to bit compare only
@BDMaster were you able to find some other bytes to change or mod because the ones you sent didnt seem to work. 
@Sweet_Kitten would you happen to know the bytes or lead us towards what we can change on legion y540 bios to get Advanced & Power tabs?
Actually, not. I’m dumb.
Patching method exists, but I can only suggest what can be done with such bios.
As you can see, in the newer model, the whole branch of operations is moved into a separate "function" and it is simply called in the subroutine. So I thought that it is also possible to find another branch that is responsible for unlock.
Do not forget that it just came to my mind, and there is no reason why the patch cannot be where it was always done.
excellent work on "how to manage the universe without attracting the attention of psychiatrists"
Hi team, you think if I flash this modded BIOS with a SPI programmer, it will unlock? Thanks
Hi!
Maybe Black Raven will be so kind and make a proper mod for you, it looks like he can.
@tompidwell we have yet to find a way to call the subroutine for all the advanced tab features, we do not have working modded bios yet. Even then, in order to keep your GUUID and MAC the same you would need to mod your specific bios dump.

Hi, I’m really excited about unlocking advanced settings on my BIOS but before bricking my device do you think it should work on Y540-15irh 81SX0005US? It has a 2060 too
In general, the patch was found.
When I started dealing with BIOS volatile data problems and packages of text strings. I wondered why some forms do not receive information about, for example, XMP profiles. And I made a small discovery for myself: BIOS menus initialization function was split.
Hi, I have a lenovo y540 17 irh pg0 (specifically) and I don’t have, as you know, access to the bios
Excuse the ignorance, but I do not understand anything that is explained here, since I do not have advanced knowledge of this subject, could you explain to me how to unlock the advanced settings, as if I were a 3-year-old child? Thank you and I hope you are still alive xd
