Install LG PC Suite, the LG Mobile Support Tool and the LG L7 USB driver. Then try again. Make sure your phone is set on 3GQCT and EMERGENCY on KDZ.

Before you install a ROM, you're recommended to wipe data.
Bootloops can occurs in many ways, if you can logcat your problem, maybe we can help you.

[Q] Stuck at security error

Hi everybody!
I have Lg g2 D802 Baltics. Yesterday I tried to return to Stock KitKat via Lg mobile support tool and Flashtool, both of them didn't work, they just didn't find my phone in download mode. Then I decided to reroot and reinstall TWRP. The first was done and the second too, but unfortunately my phone restarted and got a Security error and LG logo and can't boot, just permanently restarts. I've already read a hundreds of articles like http://forum.xda-developers.com/showthread.php?t=2432476 . The method written here isn't working for me because the Flashtool just can't find my phone when trying to install a firmware. So, any program like Lg support tool and Flashtool don't find my phone, so I can't do anything with my phone to get it to work. I'm facing i real problem for me and i'm quite shocked. So, please, tell me what to do, how to fix my phone. I tried a lot of thins, nothing helped. What to do?

[Q][Help]L2 G2 D806 completely dead

Hello guys, my name es Hernan and i´ve been using xda forum for at least 6 years with all the phones i had. But today i have a big problem with my LG and after hours of searching i couldnt find how to fix. My last hope is to post here and wish for help from you people.
----------------------------------------------------------------------------------------------
DESCRIPTION OF THE PHONE BEFORE THE BRICK
LG G2 D806 with 5.0.1 lollipop working perfectly and rooted (with oneclickroot program). I tried to install TWRP using autorec (searching on internet i´ve found that D802 apk would work for D806 since this one doesn´t have his own autorec apk). After that the phone rebooted into fastboot mode. I used this (http://forum.xda-developers.com/lg-g2/general/mega-tut-how-to-fix-bricked-lg-g2-t3055033) guide to fix it but i didnt work, then i used d802 files to fix it because i thougt it would work.
CURRENT STATUS
If i turn the phone on it shows LG logo, after 2 seconds LG security error and after 2 seconds it turns off by itself.
if you plug the phone windows doesnt recognize it all (nothing at all literally) and it shows LG logo, then lg security error and reboots constantly nonstop. :crying:
no download mode
no recovery mode

hello guys, i wasnt able to answer because i was away from home for the new year.
After considering all posibilities and realizing that there was only one way to fix my phone i took courage and did the tutorial i've found and you gave me (http://forum.xda-developers.com/lg-g...brick-t2904404). After that, the phone revived from hell and right now its working perfectly. I can affirm LG G2 is UNBRICKABLE.
For anyone who will ever read this thread in the next months/years do not desperate if your phone is dead, your LG G2 will never be a brick due to flash mistakes.

My LG F800L doesn't turn ON after H918 kdz installation! HELPPPP

Hello.
First, sorry for my bad english..
I got the F800L model and I rooted the device following the guide of Dirty Santa.
One day I read in forum that someone was able to flash H918 rom to the F800L device.
So I tried to do same.. but with the mistake of not backing up my original rom.
When I tried to flash the H918 rom through TWRP, it installed well, but when it booted, it just remained hanged in LG logo.
I just left it over a day waiting if it pass the LG logo. But it didn't.
Then I searched for the fix and read the guide about restoring the bricked device through LGUP and kdz file.
So I entered in download mode and connected to PC.
Executed LGUP software and my device appeared in H91810i model instead of F800L. I downloaded the F800L kdz file and tried to restore with LGUP but it appeared error saying kdz invalid.
So I managed to download the H918 10i kdz file and tried again to restore.. and WOW! it completed the process.
But.. Now my device is in worse condition. It doesn't even turn on.
Tried to enter again in download mode but nothing happens.. neither enters in fastboot mode...
Pulled out the battery and reinserted, and tried to turn on but nothing happens..
Can anybody help me please???

I think you destroyed your phone
You should get it to repair service

lol, u just facing the same problem with me, i did exactly the same what u do, was looking around for solution, but nothing really helpful out there, the only way i found is the method with sd card, u get the debrick img file, burn it to a 32gb sd card with the right tool, put sd card to your phone and hope it will get to downloadmode or fastboot or whatever idknow cause i'm don't have the debrick.img file for F800L, looking for it right now, people say u can get that file from the phone (has same model) that still working, that all i know for now, if u found anyway to fix your phone please told me :highfive:

It has been repeated over and over and over "DO NOT FLASH ANYTHING THAT IS NOT MEANT FOR YOUR DEVICE" and also "FLASH AT YOUR OWN RISK". Both of them together makes it pretty clear that you shouldn't have flashed something that was meant only for the h918 into an f800l variant. Developers dont write this down as fancy words or for fun. They do it in order to let everybody know that if flashed, it could easily alter your system in such a way that it might never be fixed except by the company itself. By flashing something that wasnt meant for your device, you are trying to override the system with an image. And if the developer never made the source compatible with yours, then software and hardware will be contradicting each other. The motherboards of the phones comes for its specific variants and only developers can alter an image of a system to make it somewhat compatible with the variant.
Now, lets hope you get an answer to how to fix it because LG wont be fixing it for you since you voided your warranty by a) the simple fact of unlocking the bootloader (which is pretty easy to identify since it shows the warning sign when you turn the phone on), and b) you rooted the device. And LG wont work with neither of those. Unless.... and this is a maybe because i dont know if they would agree too (if you pay the sum they request to fix it, which i assure you it will be more that $100+ maybe even significantly more). Then they fix it for you.
I personally made a backup in a separated MIcro SD card i have outside the phone. So that if i have problems with my system, then i just insert that micro sd card and restore the backup.
Good luck!

If the phones screen is blank when you try to turn it on you bricked. Only fix is a replacement. There is NO debrick.img

oh my god, if u stop at the step KDZ tool found your device that H918, I can help you. Just boot to fastboot mode and fastboot the file name bootbackup.img and KDZ tool will found your device is F800L then KDZ normally. Sorry for my bad English.

Make a hard reset, maybe it helps...:
http://www.hardreset.info/devices/lg/lg-k8-4g-k350n/
FYI lg bridge doesn't format data hence your problem was not solved - so you need to make an additional hard reset. Lg up however in refirbish mode erases all thats necessary.

Never try to apply Android update on rooted phone if it's not custom ROM. It always screws up. Try this what gottlasz said
