Luck is something I do not usually have, so let's enjoy this !!
I only found the 78CN25WW (V2.03) version. This can be flashed, right?
I post the results soon


How can I downgrade the Bios? I found a version on the lenovo site but it says it's not for my notebook (my ID is VILGV1 and I downloaded is VIWGP). Also say I can't install because it has a new version.

Thanks for help

You can downgrade bios by allowing same option in Bios setup menu.

Sorry for the delay to answer, thanks to heavy rains here in Rio de Janeiro I was without internet, I could only access today here at work.
On the website it says this Bios serves to G400, G400s, G500s and G500. It is the only one that has the lenovo site for my notebook.

I tried the version that u sent me by MP and I got this:

Ok, can you make usb bootable drive, copy Modified folder to root place and run Flash.bat from Dos mode?
