After 2 day
My problem have been resolved (by me)in this morning:fingers-crossed:
Soo good morning every body
I have got my g2 backed
I will tell u if your problem just like me
To force flash firmware without checking model numbers on your g2
1.do not use kdz file (but we still need it)
2.do not use up testEX
MAIN program we need is Lg flash tool
Just download your right kdz firmware file
Download your right tot firmware file
For model dll do not use dll given with tot file
Just use kdz extractor and extract your dll from your kdz file
Flash it with your tot firmware in lg flash tool
And Good luck:laugh:

I am in the same problem you had and I have read your solution but I do not understand how to extract the kdz.

[Q] Lg G2 Brick Security Error Bootloop No recovery, No download, PC don't recognize

Hello everyone !
I have big troubles with my Lg g2 d802.
Yesterday i want to intall crdroid 5.0 on my Lg g2 on Official 4.4.2, so i've:
Root my phone
Install CWM Manager
Set CWM Recovery
Reboot in recovery
Use ADB Mode
Use ADB on my PC to send crDroid zip by sideload
During sideload, after full download, there was an error assert failed. So installation failed, and i've decided to reboot my phone.
Problem is here, my phone boot, display LG Logo and after 5 seconds, Lg Logo with "security error" message, then stop alone and reboot again, and again.
I have tried following procedures :
Power off completely my phone and then Volume down+PWR to enter in recovery : FAIL
Volume Up and then put USB cable to enter download mode : FAIL
Connect with USB on Ubuntu to try to reset .img files : FAIL (Phone invisible on my pc, even not recognize)
So i cannot go to Recovery Mode, Download Mode and my phone isn't recognize on PC.
I don't have any other ideas and i am here to asking help .
Thxs for reading, and i pray for a miracle !

Follow this thread I think you must have seen this thread it is the best solution till date from recovering the problem you are in right now.
http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404
But you have to mess up with your phone motherboard but its really very easy. Just follow it. I have recovered mine from this.

Ok i'll Try it ! Thx you !

I have tried your link and its working. My phone is alive ! Thx you .
I have a last problem. My phone has 2 black lines on the screen from top to bottom. This appear after i had flash new .img files. Does anyone have an idea about what i need to do to remove these ?
Thx you again

Hello
I have bought my Lg g2 d802 few days ago and when I tried to root it and install recovery using autorec the phone screen went black after rebooting into recovery and still in that state.. no led, no download mode , no recovery nothing else just white lines on left corner.... I tried it to get its software repair but they said that the lcd has been fused and need to be replaced ...
I tried to connect it to pc and it is showing marshall london adb interface and in another pc it is showing Android with yellow mark which turned in to Android adb interface after installing drivers from internet
I tried fastboot.exe and adb.exe but no device found error in adb mode but some commands working as fastboot..
I want to know which partitions u flashed using fasboot and how because when i tried to flash it says cant load XXX.img (xxx belongs to the name of partition i flashed)

same problem is here....u found any solution???

AutoRec got my LG D802 bricked and now all i see white lines on screen. Can anyone help plzzzz

Look for SRK Tools here in xda
Enviado desde mi LG-D802 mediante Tapatalk

I dont think my problem is the qhsub_bulk one because my device manager detectes the phone alright does that srk tools also fixes my problem i appreciate you response

Will your phone stay in download mode? If it does, try using the LG Mobile Support Tool program and install the USB drivers. Put the phone into download mode, open LG Tools, and choose the upgrade recovery option.

Nope it stays at fastboot mode only cant go to download neither recovery

I'm new to the d802 so I am not sure if using the LG Mobile Tool or LG Fasher will work with your phone. Did you try either program?

if no one method does not help, try this:
