Ok, so how can I downgrade this BIOS? I have that .exe file from Lenovo website which is version 40. I tried with it and it gives me Error 223: Secure capsule error.
I need instructions. I don't know what to do.

Thank you,
Regards.

Have You follwed this readme :

This readme file is used for Winflash function on LG48/LG58 projects.
Please follow the below steps to update the BIOS by winflash.

SOP:
1. Check your OS is x86(32bit) or x64.
2. Run 62CNXXWW_YY.exe as administrator. (62CNXXWW_32.exe is for X86 system; 62CNXX_64.exe is for X64 system).
3. system will restart automatically.

Let me know
Regards

Done that and the following error appears: ERROR 233 - Only secured capsule is allowed on a SecureFlash System.
And the flash doesn't start.
What else? Is any DOS way to do this flash?

Ok We can try if Sleep Bug is activated yet !

SLEEP BUG :

So unpack the Bios Mod file then copy modified folder into C: HD root place !
Then open a Comand Prompt with Admin Rights (CLI) and run this comands :

cd \

cd C:\modified

Then put the laptop into SLEEP mode and WAKE-UP It again so run these comand

fptw -f bios.bin -bios

(for win7 x64 use fptw64)
and look the result, You have to get PASSED after wote Bios.bin, then let me know !
