Hello!
Without waiting for help to remove the white list, I made myself the firmware.
It is a complete firmware (including ECrom)
41CN27WW(2.03)_no_wl_by_zabses_x86
41CN27WW(2.03)_no_wl_by_zabses_x64
Collected from dumps BIOS and EC, EC removed from the dump data that contains the serial numbers of the motherboard so the firmware saved your data as in the firmware utility from the site Lenovo, only my version is newer and does not contain the white list.
Firmware tested on Windows 7 Ultimate 32bit
P.S. Sorry for my English. Google translator.
