All Keyboards dont work

[AC Question]

My phones LG keyboard had stopped working so i used google keyboard. A few days after that i shut off my phone and started it again and i got an LG security error. I factory reset my phone and then i was having the same problem with the keyboard to the point of which i could not to the setup wizard. So i bypassed it. I transferred Google Keyboard onto my phone from my computer and now it or Android keyboard are not working. I tried clearing the data and it did not work.
