Whoops, spoke too soon. Still booting to recovery.

Edit: So I tried updating my recovery because I still use the JDCTeam's fork of TWRP (the pure black one with red), so I loki patched the latest TWRP image, and wiped and flashed, then rebooted, it's still rebooting to recovery. When I flashed LineageOS 16 so I could update to 18.1 version 6, it booted successfully but not 18.1. It's almost as though it's not booting any previous roms (other than the stock rom), because it used to boot version 5 just fine.

Follow my dirty installation guide to switch GApps.

Thanks, will do.

I have another question; since 18.1 the vibration intensity is VERY low. I have followed the googled instructions on how to increase it but the mentioned menu only shows on/off switches, no bars to adjust the intensity whatsoever.

How do I do this?

Via Root and Kernel Manager. On Official OptLos and crDroid vibrations should be normal.
