Did factory reset on a rooted phone.

I rooted my android cell phone and then I uninstall some apps in my phone tried to save space. suddenly my phone frozen. I couldn't start it. then I made a factory reset. after reset the cell phone shows blank screen and on the top can see some status like wifi, power.I haven't install any recovery app and ROMs. I think I need flash my phone. I read a lot on the website about how to flash cell phone, till can't . some post said set usb debugging mode, problem is cell phone can't start how to set usb debugging mode. any idea ? please
 
Easiest way to fix it now will probably be to flash the zv9 update.zip from stock recovery
