booted into recovery and now phone wont boot up topic

hi guys. Idk what happened to my phone. never had this happened to it before. my phone has been working properly. I have been running smooth rom2/3 without any problems. I then wanted to try synergyrom mk4 so I downloaded it. i wanted to backup my rom just incase something went wrong so then I boot into recovery( teamwin recovery) it booted and the logo of teamwin stays on then blinks then stays on and blinks... I tried pulling the battery and just turning the phone and it still goes into the teamwin recovery logo.

idk what do to. someone please help me...
