I had just recently rooted my LG Leon with Kingroot and decided to deleted some apps. I deleted the default texting app and now when I try to turn on my phone it says "security error, authentication fail #9". I was on rooted 5.1.1 with the default ROM, and it is for TMOBILE. I have already booted it into recovery mode and did a factory reset but nothing changed. How can I fix this?

I recently bought an LG G2 off of a friend, perfect condition and it worked as expected.
As i do with all of my phones i went to go root it, easy peasy. 5 minutes and done.
I googled a video on how to install roms on the G2. (This is the D802 version from Tmobile by the way, that was running Lollipop already).
The video told me to download this app, and itll install a recovery automatically. (AutoRec). He replied to someone in the comments saying that it would work for lollipop as well.
So.. without putting much thought into it, i went ahead and did it and got this screen.

Yea.
I searched every single forum post on here about how to fix it, and all ive managed to get is this.
http://gyazo.com/7f37907b7815ed63645255a313fa356e
The grey bars are gone, but the fastboot screen is on.
I CANT get into download mode. I CANT get ADB to recognize my phone. Under device manager my phone appears as "Unknown".
I have tried everything suggested on the forums. Flashed laf.img over and over flashed and erased recoveries etc etc EVERYTHING. So my phone is basically just a blackscreen with some text.
Is there a way to reset it to ultimate default settings, i dont care about recovering what was on there at all. I just want to be able to use the phone.
ANY help would be appreciated, if not im just going to resort to this: http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404

Hello, I am new to this forum but I am of need in help.
I recently rooted my LG G Vista(5.0.2), but apparently it was temp-rooted because everytime I would reboot my phone it would get unrooted.(I used KingRoot, nothing else worked for me).
So then I was like **** it, I factory reset it and after that it sent me to the LGSetupWizard and I entered in my information etc, and when it got to the very end it says: "unfortunately lgsetupwizard has stopped".
It just goes in an endless loop, any ideas?
Thanks - Zach.

[620]
the phones has 5.1.1 lolipop and is rooted, and i used kingroot to root and switched to supersu using a guide i found. not sure if download mode work because its just stuck at 0% for some firmware update. but my pc does detect it in device manager but it says "this device cannot start (code 10)".
