thanks bro actually I'm scare because I saw this man while downgrading he lost his bios! I do not know if I lost my bios or not!They probably won't work. Lenovo is really strict with these Whitelists. Is there any reason why you are so opposed to patching the BIOS? It's a relatively simple process, once you've collected all necessary files and tools. As long as you don't flash anything before checking thrice that you didn't get errors or forgot some steps, you should be fine.
so how should I set bios before downgrade?
I mean how to configure the bios setting before trying to downgrade??
