KF2 keeps booting into TWRP.

[128keaton]

Hello all. I got CM11 installed on my kindle (finally). I installed 'SuperSU' from the Play store and it prompted me to install something. It rebooted into TWRP and I cannot get it out. I've done every single wipe, reset, or erase available in TWRP. I've reinstalled CM11 multiple times, without any effect.
