Yes, I seen the info that the modified (or backup-ed) bios can not be flashed on this PC (because of the built-in BIOS protection). So, can you try to flash the your bios backup using AFUDOS (or wflash2.exe) utility?
I know I can flash bios from lenovo's web site with lenovo bios utility, I can try and flash with afudos, do you know the parameter I need to use (Like /o /f...)?
Espy has a Lenovo E330 and your saying that his bios has some kind of protection. My notebook is a relative of his the Lenovo E430 if there is protection in his bios then there is a high likely hood that my bios has the same kind of protection, but what kind? Are you referring to RSA signing or perhaps some form of encryption?
the second mod you added BIOSSLIC2 is the the BIOSSLIC like in the first mod ? in the zip file there is only one file
