Default [Q] Resetting the phone and stuck

I have a rooted verizon galaxy s4 and because of some problems (rebooting randomly) I decided to factory reset the phone. So I went to settings, accounts, and reset the phone but now its stuck at this screen with a green android bot and below says Downloading... Do not turn off target!!
Its this screen for like 30 minutes now... What should I do???
Thank you so much
