@sergeyshibaev228 - Please confirm, no error when you do below #1+2?
1. FPTw.exe -bios -d biosreg.bin
2. FPTw.exe -bios -f biosreg.bin
Yes, that’s right.
Here is my dump (biosreg): http://s000.tinyupload.com/index.php?fil…992773124967200
@sergeyshibaev228 - Thanks for confirmation
Please zip for me image of the BIOS, so I can see across top, what all section visible to you already.
Thanks
Photos of the settings that are now available to me (sorry for the quality): http://s000.tinyupload.com/index.php?fil…026014310303819
Does this work, if so you don’t need to edit BIOS >>
Enter BIOS via F2
Click >> More Settings
Hold FD + R then FN + N
Then quickly press F10 then save and exit, enter BIOS and see if unlocked?
Unfortunately no, nothing appeared.
@sergeyshibaev228 - OK, then we’ll see if we can unlock the menu 
Flash this back via >> FPTw.exe -bios -f biosregm1.bin
Do you now see Power + Advanced?

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don’t try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)
WARNING *** - This BIOS is user specific! If you are not user sergeyshibaev228 at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not sergeyshibaev228, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!

Hi
Thank you very much for your help!
But I had a little problem, I exchanged that laptop for a laptop of the same model, as I got a defect with sound.
Here’s my new dump: http://s000.tinyupload.com/index.php?fil…368456074155419
I can still write my dump via FPT
Hope for your understanding, thanks!
@sergeyshibaev228 - You’re welcome, and it’s no problem! Here you go - http://s000.tinyupload.com/index.php?fil…478468874466126
Flash this back via >> FPTw.exe -bios -f biosregm2.bin
Wow! The hidden settings were displayed and everything was sewn the first time!
Thank you very much for your time !!!
@sergeyshibaev228 - You’re welcome!
Great to hear all is there now, and than you for the quick report back! 
Good afternoon.
I have a Lenovo Ideapad Gaming 3i and I need to access the BIOS settings. The bios version is egcn34ww.
Could you teach me how to unlock these options or send me a file with the advanced option unlocked?
I thank the attention.

Hello!
Run “GET VARS.bat” from this archive and share the output file “vars.txt”.
I also need your BIOS backup. Use BACKUP_Tools to get the “results.rar”.
I did it as soon as I saw your message, sorry, if it took a long time
