Original works better then supplied EFI

[ozintIsrael]

I installed Big Sur by copying the EFI that you supplied to the USB.
The install was formated over a copy of Windows 2019 Server.
When I boot the system I am using the original EFI that the MAC has on the hard drive.
[Without the USB it boots into windows recovery partition]
I boot the system with the USB in the computer and choose the osx volume.
Everything boots normally [Bluetooth and WIFI both work!] (in the bios I have both Bluetooth and WIFI checked)
everything just works....
When I copy the EFI that you supplied to the hard drive,(I backed up the original EFI) and reboot Bluetooth stops working. Screen resolution is better (5-10%) but other then that everything else is the same.
I am probably missing something else in the drivers that you supplied, but right now using the original EFI allows me to use Bluetooth, with a minimal drop of resolution.
I am using version 11.2.3
The only issue of using the original EFI is that I have to boot the computer everytime with the USB. If you want the original EFI I am using let me know.
