Keyboard stops working help :(

So guys I managed to install mac os Catalina on to my predator Helios 300 laptop. Then I copied the contents of oc from my usb flashdrive into the efi folder (as to dual boot) And then I went ahead and copied all the kexts to the desktop and installed them using kextbeast into L/E folder. Went into recovery and typed in csrutil disable (sip disabled) Then got back in to the terminal and typed in Sudo kextcache -i/ And everything says invalid signature (-67062) allowed

So then i rebooted into my system and logged in And noticed my laptop keyboard stopped working after a couple of seconds. External USB keyboard works also the trackpad never worked. But the keyboard stops working and it's getting annoying trying to find the problem

Did I installed the kexts in the wrong way or something? What do I do?

Any kind of suggestions would be appreciated thank you :)
