Update,
I fixed this problem by using LGUP. My phone was refurbished (ls980) so that's why twrp didn't booted,
Hello,
I have a LG G2 d802 32gb variant. I bought it a week ago. I was running andoid kitkat OS (HK D80220C). It wasn't rooted. I tried to get official updates from about phone section but "no updates". So i decided to manually flash updates from a rooted recovery as i did in my LG G3.
First of all I rooted it by "IOroot". Then tried to install custom recovery by "autorec d802". Everything went good and autorec was also successful. I asked me to reboot into recovery, I pressed yes and then it took me to "fastboot mode". I tried to reboot into OS by pressing power button (As battery is non-removable). Everytime it rebooted back into that fastboot mode. This once happened with me on LG G3. So i tried to flash "laf" and "recovery" image and downloaded from here
http://downloads.codefi.re/autoprime/LG/LG_G2/D802/Stock_Firmware
I flashed them by CMD fastboot method. Now it stuck at "LG Logo" and download mode was also started. So i decided to install a stock rom by KDZ or Tot method. First i tried KDZ method. I downloaded stock rom "Hong Kong D80220C_00.kdz" which it was previously running. Also installed all drivers, downloaded flashtools2014 and connected phone while in download mode.
I started KDZ method as told here
http://forum.xda-developers.com/showthread.php?t=2432476
But everytime it shows internal error on "2 or 3 percent". It didn't worked for me. So i decided to do tot mothod.
Download tot file, dll file, LGFlashtool, drivers etc.
Followed whole process which was also described in above post. But when flashtool reached at 94 percent and mobile was being rebooted it showed error
"Fboot check"
"Fboot Check"
"Can't reboot completely"
I tried to turn of phone at this condition by waiting and then doing a factory reset by keys combination but it keeps resetting and rebooting. I searched whole internet but can't find a solution. Can anyone please help me. Because i bought this cellphone a week ago for my friend and i would not be able to face him after showing a sick phone. Please someone help .
Only download mode of phone is working, It also keeps led light on while stuck at logo.

Hey Guy,
Im a Noob. I bricked my phone trying to install a KitKat Rom and a Custom Recovery, and now it wont boot past the LG Logo Screen. I've tried the .kdz method and the step that says "Select country and language" window that never pops up. The TOT method gives me an error stating my "device model is different."(View attachment for error and dll file). Ive search every possible forum looking for different methods on trying to flash the stock rom. I can only access Download Mode and Recovery Mode(ClockworkMod V.6.0.4.4), I've attempted to mount USB storage through recovery but thats not working either. Ive also tried doing a "Upgrade Recovery" through the LG Mobile Support Tool and it spends like 3 hours downloading the firmware but never installs.
KDZ Method.

hello guys,im new here i need your help..
I bricked my d802 today,i was on stock kitkat rom,what i did was rooted my device with towel root and used Autorec to install recovery,it installed successfully,then i clicked ''go to recovery'' then all i get were white lines on one side of screen and rest of screen is black(cant see anything).. after digging for hours i came to know that it is because of different Kernel version,but now i want to know how can i flash patched Kernel? as my device is bricked.. It is also not going into download mode so i cant also flash a stock rom.. tried Adb but it is not detecting my device... im completely lost
A tutorial or help will be appreciated.Thanks im waiting for your replies
EDIT:
i used fastboot commands n flashed some img. files..now my display shows up(dull white lines are still on it)..i can boot into download mode now..i flashed kdz stock rom it completed successfully.. but after reboot it is stuck on lg logo with led on... i did hard factory reset(holding volume down key + power button) but it is still stuck at lg logo.. i can still boot into download mode and i dont have a custom recovery installed what should i do now?
can i flash custom recovery using fastboot command? because ADB is not detecting my device. but computer is detecting my device(it also installed three drivers automatically)

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
I've got a T-Mobile D801 and tried flashing to the stock lollipop rom D80130b_00 using TWRP and the instructions on this page, but the flash must have failed. I did a full factory reset back to stock 4.4.3 prior to attempting this flash and I'm not sure what (if anything) I did wrong for the flash to fail. I can boot in factory reset mode and select clear everything, but then I just see the android guy with gears turning for 2 seconds and the phone reboots again.
Now I'm in a bootloop where I get an "error: Boot certification verify" above the T-Mobile startup logo followed by a "Demigod Crash Handler: Critical Error!" screen that provides options for rebooting (volume down) or putting the phone into download mode (volume up). After using the volume up the screen displays "Volume Up is pressed: Jump to Dload mode" and after connecting via USB appears in device manager as "LGE AndroidNet USB Serial Port (COM41)". I can't (1) boot directly into download mode or (2) get back into TWRP.
I've tried both the KDZ and TOT methods listed in this thread and neither are working. The LG Flash Tool 2014 / KDZ option starts the LG Mobile Support Tool, but it fails every time once "S/W Upgrade is in progress" reaches 4% with a generic "Upgrade stopped due to an error" message.
The TOT method fails every time with a "Model Information Check FAIL!" message. The full text is - "PID: NULL, IMEI: NULL, Model: , DLL:801, BIN: BIN_LGD801AT-01-V10c-310-260-AUG-13-2013+0.tot , SWV: , SWOV: , Model Information Check FAIL! , 00000000"
I've also tried using srktool to repair fastboot, but it gets stuck at "waiting for device".
What do I try next?
Finally got back into 4.2.2 using tot method. LG Mobile Support Tool doesn't think updates are available though??
same situation lg g2 d802

Yes, I *think* what happened was that my 30b bootstack was flashed successfully via twrp, but then the actual kdz flash of D80130b_00 failed. I had a lot of trouble at this point - needed to fix qhsusb_bulk problems first, then use the more aggressive TOT flash method to reset to stock 4.2.2.
Finally the LG Mobile Tool was still reading it as having D80130b_00 / lollipop after going back to 4.2.2 via TOT (?). Last step was to do a full restore from the LG Mobile Support Tool (options -> upgrade recovery) and it actually downloaded / flashed D80130b_00 so everything is working well now :good:
If it helps anyone I used the LG backup tool to restore apps / media and have to say that for a stock solution it's pretty solid.
qhsusb_bulk?

you said your g2 was detected as a lge androidnet in device manager but not as a qhsusb_bulk...then what problems have you fixed about qhususb_bulk? and what is the more aggressive tot method different from this threadhttp://forum.xda-developers.com/showthread.php?t=2432476
Were you able to find a solution? I'm in the same situation. Please help!
Hello
I'm new here, I've been modding my lg a few times, always when bricked, kdz or tot files were saving me.
But now I've got real problem.
I was changing ROM from Cyanogen 13 to Cloudy 3.3. I thought I just need to flash rom via recovery (2.8.7.3 bump blastagator). Flashed fine, without any troubles, but when it came to reboot, phone just got stuck on LGs logo.
I knew i f*ed up.
Recovery isn't working, but Download Mode is turning on normally, at least it seems to.
So i tried to flash KDZ, but LG Flash Tool immedently shuts down giving "lg user...." error (don't remember what exacly it was saying).
Then i tried via tot files. But after installing drivers from tutorials, device isn't showed as "LGE AndroidNet USB Serial Port", but as few positions like MTP device or usb serial port(but not in Com ports) and all are marked as devices without drivers. Flash tool for tot also didn't worked here, because it did't found device.
What can i do now? Please help me.
[Edit]
So now, using different drivers somehow Jelly Bean installed by tot method (device didn't appeared as tutorial said, but it worked) phone is booting normally, but i can't again install lollipop with kdz files.
I was trying 3 different drivers, every giving instant error of flash tool.
What can I do now?
[EDIT2] LGUSERCSTool.exe is crashing. How can I install lollipop now?
Are there tot files for lollipop?
Hello,
I'll try to detail as much as I can to explain how i ended up Bootlooping :
I tried today to root my LG H870. (imported from Germany, according to the seller).
I followed the tutorial on xda to unlock the Bootloader on the device.
After flashing it, it launched Android the 1st time without difficulties.
I rebooted into TWRP, flashed supersu, then rebooted into Android. Problems started there, the system told me my partition was encrypted, and asked if i wanted to reinitialize it. After doing so, it's been stuck, bootlooping to TWRP, the internal partition empty.
I followed numerous tutorial on how to flash a stock ROM through TWRP, Fastboot, ADB Sideload, without any success.
With TWRP, it was always ending up saying the flash wasdone, without writing a single file in the partition.
I also tried installing stock ROM with LGUP, but once again, didn't seem to work. While in download mode, it was either telling me the phone was an unknown model, on port COM3, or that there was no handset connected.
I then followed another guide, using LG Firmware Extract and LG Flash Tool. It didn't work as expected, but, I don't really know how, it made LGUP seeing my phone correctly. I was then able to flash a stock ROM (H87010f). No error during the process.
After the LG Logo, i get now a blue screen, saying for some seconds "Encryption Progress", and after that "Factory Reset Status", with a big red "2", and it gets stucks there.
Once again, if I get into download mode and into LGUP, i get now the "no handset connected" message.
Is someone on here able to help me?
If more infos are needed, tell me, i'll try to answer!
Thank you all!
