[Q] ROM Flashing and Load Screen Problems topic

CWM v6.0.1.2 is installed but when i try to install ROM from .zip from the external SD card and reboot it stays on the 2nd load screen. 1st screen just says SAMSUNG 2nd screen say Samsung Exhibit II 4G exclusively for T-Mobile (This is where it hangs and doesn't move). Can you please tell me what I'm doing wrong or what should I do? Any and all help is appreciated. Thank you in advanced
