Thanks for this great post and for your help, Finally I could do it that and removed the whitelist :D :D.
After many times I tried with no luck, I checked all questions and answers over and over, Finally managed to do it so Thanks a lot.
I've one last final question since you are using Lenovo in general, My laptop is Lenovo z50-70 which WiFi card is best for this laptop? I got DW 1820A and the card is working great with windows but while the wifi is on from the bois i can't boot in to the macOS so now i'm turning it off from the bios and looking for another compatible card, Do you have any recommendations ?.
Thanks in advance

Please read posts from #58 to #61. If you found the very same values at the very same offsets and modded the bios properly you can flash it.
