I've tried multiple times to install twrp 188.8.131.52 with no luck. I tried adb and flashify. It does install and boots into the newest recovery. When I try to reboot back to cm 12.1 it just reboots back to the recovery over and over.
It sounds like you installed the recovery fine. But it also sounds like you may have installed the recovery to your boot partition. That's not the recovery's fault . . .
