My phone won't boot after trying to install custom ROM.

[AC Question]

My Samsung Galaxy Note 3 T-Mobile won't boot up. I rooted my phone, downloaded Cyanogenmod, and copied it to my phone. And then I went to Rom Toolbox lite Installed the TWRP recovery, went to the ROM installer, selected Cyanogenmod, and went to boot into recovery. But now my phone is in a boot loop, and the phone keeps booting into recovery but isn't successful so it does it again. I have tried to boot into download mode, and have looked everywhere on forums for a solution, but could not find one.

Whenever it boots up it shows up with the Samsung Galaxy Note 3 Logo, and then at the top left corner it says:

RECOVERY BOOTING.....
RECOVERY IS NOT SEANDROID ENFORCING
SET WARRANTY BIT : recovery

I would be so thankful if you could help me through this.
