Not a guide. Moved to laptop support.

Boot in single user mode. Remove whatever you installed. Rebuild cache, reboot.

To rebuild cache:

mount -uw /
touch /System/Library/Extensions && kextcache -u /

Note that on a real Mac, you must disable SIP in order to install unsigned kexts/modify system files/etc on 10.11.

No idea. Restore from backup or talk to Apple.
