I was able to flash my drivers and remove the whitelist. I'll like to thanks patrick1234578 for his post #60 and the OP daigosx and RehabMan and everyone else that contribute to this thread. The main problem that I had as I suspected in post #246 was that for some reason The windows 10 upgrade removed my video graphics card completely. Which for some reason it send the computer into hibernation instead of sleep, when I closed the lid of my computer. windows 10 battery/ sleep and power management tool would not allow me to change from hibernation to sleep. To fix this

– On the Desktop, right-click on This PC and select Properties

– On the left, choose Device Manager

– Click the arrow next to Display Adapters to expand that category

– Right-click on Intel(R) HD Graphics Family and select Update Driver Software…

– Choose the option to Search Automatically for Updated Driver Software

– Your computer should find and automatically install the updated driver

– After the installation is complete, restart your computer

This resolve the computer sleep problem. them I flash as recommended by patrick1234578

Having a nightmare here! At the final stage. I have the modded bios .bin file and I'm trying to run the command and getting the error, so I thought I'd try the sleep trick however, when I shut the lid so the laptop sleeps, turning back on it just restarts. So now I'm stuck. Any alternative programs to flash it other than FPTW64? Thank

Yo are probably missing some drivers for Windows. Try to fallow steps on my last post. If you are still having problems, download the graphics drivers from Lenovo website. Hope this help.
 
Fallow the guide and read thru all post on this thread. All solutions are here trust me. I had your same issues. If you have any questions post them.

Update: hackingtosh on High Sierra everything works perfectly including Bluetooth, airdrop, FaceTime AppStore . Thank you Tonymacx86.com forum staff.
