[REQUEST] Lenovo G580 (5ECNxxWW) Whitelist removal

[digipokemon]

Hello, I'm new to the forums. I have a Lenovo g580 model 20150 with Win 10 Home clean installed after an upgrade from pre installed Win 8.1.
The bios is 5ECN96WW(V9.01) with the motherboard stated as "INVALID (U3E1)" in speccy, possibly due to parts I replaced or from upgrading to Win 10 from what I read around. I was trying to upgrade the wifi card for a better one and noticed this thread while looking around. I had a few questions regarding this bios mod before proceeding.
1. Is this removal of wifi whitelist considered a particularly dangerous mod? While most of the people who requested didn't seem to have problems from the mod BDMaster gave them, the last poster seemed to have quite a bit of problems.
2. It seems that each person has to upload their own bios backup and get a modified whitelist removed bios specifically for their own laptop. Is there a reason for this?
3. I understand that SLIC 2.1 signiture in the bios is the key to get OEM Win 7 on computers. The laptop only seems to have the win 8.1 key embded, but would it be possible to add SLIC 2.1 at the same time with whitelist removal? While Win 10 Home by far better than 8.1, I'd prefer to have Win 7 installed on the computer.
4. would doing the whitelist removal with or without adding SLIC 2.1 remove the win 8.1 key from the bios?
5. Finally, what would be the best way to backup my bios so I can upload and get the modified bios?
I'm sorry if these are a lot, or are dumb questions in general. I know better than the average person regarding computer repair and re installation, but hacking and modding things like bios is beyond my knowledge. Thanks for whoever answers me in advance. oh and a bit late Happy New Years!
