LG lc34~ all apps crashing. doesnt boot properly.

[AC Question]

this phone stays at the lg logo screen, if i attempt to continue to boot by regularly pressing powering on i to will eventually boot but all apps crash. sometimes in the process of this loop to get it to eventually boot it has a message at the top of the lg logo screen that says "boot security error" or "boot verify certification" etc (it says a few things but to breif to read all). it sometimes says home has stopped working. i tried restoring to factory. ive tried booting into safe mode. a few weeks ago the lg keyboard went blank and gave the "error" message. i started using google keyboard. i don't know what "rooted" means so i havent done that in any way.ive also taken out the battery and remounted sd. thanks

I had this problem this morning and went to the forum where it was suggested to go to the Google Play Store and Install Google Keyboard[/U] that is Free. It worked like a charm. That saved me trouble of clearing data.
