I tried, but I think this is not my level …
Can you please give me the unlocked bios directly if you have a few minutes ?
Thanks in advance
Is this possible for you ? 
Currently I’m not open for requests. I just have no opportunity.
Many thanks !

Thhanks, i’ll test
Huge thanks ! Working !!
How did you do this if you want to share
hi, I can only translate very short. I know you have ida. So do as the kitten says. Select 16 bytes after looking for “0E A7” in ida. Skip through the labeled data and it will take you to the critical places.
Hello everybody. I own a goofy Xiaomi Mi Notebook Air 13.3 i5 8250u MX150 1D12. The bios (Insyde) has no advanced options!!! I have read @Sweet_Kitten 's solution to this in a similar topic by replacing a tab by modifying GUID and FormID. But now I found this topic and my Bios editing knowledge is not sufficient to understand this 16bytes mod (@553349149, pls explain lol). Thus I wish for anybody to, please, explain this modification and help me with unlocking advanced tab in my bios.
I am going to attach my backup.
Thank you in advance!!!
Hello.
There is a lock inside BiosRegionLockDxe in Xiaomi Air 13.3. It prevents write acces to bios space.
yes i know i have flockdn and i saw this guide on removing it. i also have a ch341a
Great. Should I also remove flockdn in mod?
If you are able to mod my bios, then I would gladly accept it. Do you, by any chance, know sources from which BIOS/UEFI structure can be studied? I really want to understand how hexidecimal code and variables are stored and structured as well as implemintation of Assembly. (also what registers are and how they are edited). Thank you in advance.
