zillion thanks BDmaster!! you're my hero!
Finally thanks for your reply !
I think these would be the mods :
unlock infinite loop :
0BEB : 75 F5 to 75 00 or 90 90 jnz short loc_BE2 to jnz $+2
unlock whitelist :
0C7D : 75 2B to 75 00 or 90 90 jnz short loc_CAA to jnz $+2
0C92 : 75 16 to 75 00 or 90 90 jnz short loc_CAA to jnz $+2
0CA8 : 74 1B to EB 1B jz short loc_CC5 to jmp short loc_CC5
Let me know, if It's right !

i have tried to see how lenovo's official bios update works, looks like the authentification for secure capsule is in winflash64.exe.
(i used win7 64bit).
it's in the oem check section.
kind a hard to understand all of the assembly. IMO, this is much more complicated than removing whitelist.
i will write how i setup my system to be able to debug and patch the winflash64.exe in .docx format.
hope someone with better understanding of assembly language and programming than me can fix the oem check.
Then hardware based flash update for T430, x230 (and perhaps other lenovo series) is not necessary anymore.
