Stuck in boot loop - install Big Sur

[PestJaw]

Hi @wstrohm !
So, I tried the both configuration during fews weeks : one with yours kext, and "my 1st config".
The "my 1st config" it's more stable than with your kext, but I don't have a full stability.
I dont'f find if "IntelBluetoothFirmware.kext" and "IntelBluetoothInjector.kext" are the correct kexts.
The stability is not perfect but work well, I think i can do with that.
