Hello, i have a problem, i dont know if its a big one or a small one for you, but for me its kinda big. Two days ago, i have downloaded a bios update from the lenovo support site, i didn't looked on my actual version of bios, but i have discovered that I actually did a downgrade, not a upgrade. My actual bios version is E0CN61WW, and the previous version was E0CN63WW. My question is the following: Can i receive please my previous bios firmware?

I have just received E0CN63WW today (in fact I installed it a few minutes ago). Got it via Lenovo Vantage (you should install it, you can get some hardware support quirks you can't get otherwise)
There is a setting to disable bios downgrades. You should find it on the Security page, next to Intel Virtual Technology setting.
