bootloops after install of font app

LGMS769

recently rooted and downloaded all the nessential apps, including recovery however upon installing the apps one requested a reboot ( font changer ) as i reboot the phone i get boot loops. this went on for a while i tried recovery and then, not before i happened the recovery app tells me my model isnt supported. so i try a few things and then get the dead android with red triangle. i got it to boot back up without the dead android, but phone is still stuck in boot loop. any suggestions other than factory reset ? oh and i had made a backup prior to rooting but hadnt seen or noticed my antivirus decided it was a virus and removed access to it, now for some reason when i try to open it, it opens free file viewer.
