Managed to delte an Essential kext, how can I put it back when I can only boot into install via USB?

Hey,

on my quest to fix the problem that my Hackintosh is restarting when shutting down I stupidly deleted the OSXAptioFixDrv 3 form the EFI64 folder. After testing if the shutdown is working now I get stuck after the randomized command.

I have my old USB and can boot into the install mode, however, I have no kexts in hand and as a noob I would not find out how to install the kext back into the EFI partition with terminal.

Can someone help me guiding through?

so much thanks in advance!!!
