Try to make a factory (hard) reset: [Only registered and activated users can see links Click here to register]
Also maybe reflash via lg bridge. Make sure you boot up after bootloader unlock and then go to fastboot and boot to recovery, don't flash it.
If this doesn't work, try to port a recovery for yourself:

You can use that LGK8TWRP as "port" or you can also try to use Singular777's twrp ([Only registered and activated users can see links Click here to register]&postcount=126]) as "port".
