Default [Q] Every flash fails

I'm currently using the stock 4.1.2 rom from Sprint, have TWRP 2.6.3 installed and the phone rooted. Every 4.4.2 rom I've tried to install fails and I have to restore my TWRP recovery.

I've tried CM 11, AOKP, Pac-Man and a few others. I've been copying the rom and recommended GAPPS to the internal storage, rebooting to TWRP/recovery, doing a factory wipe then 'Installing' the new rom. Most fail almost immediately, I'm really not sure what I'm doing wrong.
