Use this tool: http://rghost.net/7VNMwQF4V
Run exe as admin, upload results.rar
(And what you need for mod? Remove WL?)

Yeah i need remove whitelist.

Here is results file:
https://dl.dropboxusercontent.com/u/2741044/results.rar

But i got some red errors during process, i think that bios backup above si better.

Second question is what utility i need to flash modded bios, official Lenovo windows one, or some flash tool for Freedos?

Sorry, i dont understand. some hash..

What i should to do? I would like to just to get some bios rom file and utility and run the flashing..

The UEFI Bios is RSA Signed and Locked so will not permit to Flash an older Bios Mod !
To Downgrade then Boot your Laptop in Bios Maintenance (may be You have to use NOVO Button)
I haven't any Lenovo laptop so I son't know perfect It (just experinces by users and knowlwgements)
then Set to ENABLE RollBack option and save Settings !
Reboot laptop into Windows env. and run the tool as Admin and upload the result for the version 2.52
and We will prepare a modify !
