Default [Q] Trouble upgrading and installing CM11

I have a Samsung Galaxy s3 on Sprint. I'm trying to install CM11 4.4.2 but am having trouble. My phone is currently running 4.3 rooted (used cf autoroot and philz touch 6 w/ CWM

Here is the issue I'm having; I cannot install the CM11 rom, from the recovery (philz touch) screen it looks like it completes but the phone does not boot after installing the rom, but rather hangs the recovery screen logo and doesn't progress. From here I can reboot into recovery and restore my backup, The only backup I have is of 4.3 rooted. Also, I cannot install the OTA 4.4 update from sprint, which I thought I may need to do before installing CM11. When I try to install this update,the phone restarts into recovery and installs one package then asks if I want to install a package from an untrusted source, I hit yes the phone installs then restarts back into 4.3

I would like to update the phone to 4.4 and run the latest CM release, if anyone could help I would greatly appreciate it
