My headphone jack was broken so I called my insurer and got a repair scheduled. Before sending it in, I wanted to reset to stock for them. Afterwards, I'd flash a new ROM. I was running Mahdi from August 28th 2014. It was about time to restart fresh. Now, I downloaded the KDZ for my IMEI, which was D80220H. The last one I used before that was D80220F. Loaded up my flash tool, went to town. About 30% in it reported an error and quit. The app adviced me to reboot the phone, so I did. That's how I got where I am now. Phone does boot, but after the LG logo it goes into a black screen and shows up in device manager as QHSUSB_BULK. I've tried the guide for this, replaced all the partitions with the images from the D80220H KDZ, but it hasn't changed a thing. What can I try to get it working again? I've heard people say this phone is unbrickable, so I hope I'm not lost yet.

The perfect storm...
I broke my phone about a month ago, bought a hold over on craigslist until I fixed my phone. Left the phone stock and yesterday sold it to a truck driver via craigslsit. I did a factory reset handed over all good to go. He is now out of town
This morning he calls me and says the phone is locked in TWRP and is politely upset. Confirmed the phone worked when I gave it to him. I did not install or root this phone so the crap ass before me must have and did it and not mention it. The guy has no clue what happened, went to bed fine, woke up and stuck looping in recovery.
I tried to walk him through it. Reboot, says it lands right back at TWRP. He seems up to the idea of using a tool or utility to flash it.
I found this thread [Guide] Unroot/Unbrick - flash official factory firmware with LG Mobile Support Tool but it does not seem to cover the Verizon variant.
Can anyone point me to some instructions I can send this guy on getting this thing back to stock?
Hi guys, I got my LG G2 a few months ago and it was my first android phone. Since I always jailbroke my apple devices I decided to root my lg g2. Everything worked fine until last week when I was prompted to install a software update. I thought this might mess up the phone since it was rooted so I postponed it until later in the day to give me time to research, but I forgot to postpone the update again and it went through at the scheduled time. Now when I turn my phone on, the lg logo is displayed, and then I get a boot certification verify error. I don't really know what that means but I can't do anything, no recovery, no download mode. I started to follow this tutorial but am stuck at what files to download. I do not know if I have the 10b, 11a, or 12b variant, and I can't find a way to check it without turning the phone on, which I can't do. I'm really lost at what to do at this point, I can't follow the only guide that might fix my phone. Is there another way to solve this issue or find which variant I have? Would verizon accept it back to fix or replace it since it's been rooted? I've read some people saying they unrooted their phone and then returned it to the carrier, is it possible to do that in my situation? I really need some help guys.
TBH: I would call Verizon, and tell them the phone was bricked by the update- hope they don't notice it was rooted when they warranty it. Problem is, if they do you get charged full amount for phone. I'd consider if you have insurance to just claim it on insurance.
try download lg support tool from lg website http://www.lg.com/uk/support/software-manuals
plug the device and wait for the software to recognize ur version.
I downloaded and installed it, but it won't recognize by phone. I have installed the drivers for it
ok.
try to follow this guide http://forum.xda-developers.com/showthread.php?t=2681089
and the files download from here:http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware/10B_Partitions
lets try this virsion and see what happend..
download the 10B zip file and the dll file too http://downloads.codefi.re/autoprime/LG/LG_G2/VS980/Stock_Firmware
now it doesn't boot at all, not even to the lg logo. Additionally the partitions don't show up in ubuntu any more. I guess i'm completely screwed now?
Hi all, hope you can help me. I've tried searching on the internet but no-one seems to be having any problems like mine. and my phone is now near enough bricked.
So i bought a LG G2 D802 from aliexpress, all working fine but no 4g lte option for some reason. Had a look around and seems updating to stock europe rom would have sorted this so i thought id do this.
So Updated the rom using flashtool2014, downloaded lg usb drivers, the europe rom D80220D_00 and lgmobile support tool. Went through the process and it all ran fine with no errors completed 100%and then said done pressed exit and disconnected phone.
Now, switched phone on . Straight away touch completely messed up click on the screen and different parts keep of the screen keep clicking. Eventually after 15mins managed to get out of the startup where it asks for wifi settings etc so i could try to factory reset. No luck even out of startup have not yet managed to get to the screen for usb debugging yet due to random screen clicking (keeps opening other apps, screens).
I cannot rerun the flashtool as i cannot enable usb debugging or even switch away from charge only to pc softwarw and it just says phone not connected on the flashtool and keeps ending.
Switched off by holding power button for long time. Holding down the down button and power does nothing just keeps restarting when i eventually let go.
Also sim is in phone but it says service disabled?
Any ideas how i can fix the phone! All was working fine before I did the europe rom update
Thanks
Jon
You can connect a mouse via otg and navigate to usb debug
Sent from my SM-N910H using XDA Free mobile app
Maybe try factory reset and just use mobile support tool update stock rom?
Sent from my LG-D803 using XDA Free mobile app
I would just use a wireless keyboard with an otg cable like sugested before

I eventually managed to select lg software as connection mode and flashed to another firmware but exact same issue again.
After trying for ages and opening the wrong thing again and again i managed to get to the screen in settings to click 5 times to enable developer options however now the screen just freezes and then you get a message saying settings has stopped working and phone locks up. This has happened 3 times since. Doesnt seem like anyway to get it sorted if i cant enable usb debugging.
Also it seems to be that the firmware change has erased the imei and that is what is causing all these problems. I found one site that details how to restore but once again you need usb debugging enabled.
Droidview has the page where you have to backup and restore imei, i dont have a backup so will need method 2. If i can get usb debugging enabled that is!

Try using onscreen phone maybe you could manage to set that up and then enable usb debugging?

thanks for all the help, lg on screen just didn't work for some reason wouldn't connect to the phone. Was thinking about a otg cable but after an hour of clicking again and again I managed to get the developer options and usb debugging enabled.
I went through the procedure at droidview to restore imei using qpst but after finding the com port it says no phone detected so theres nothing more I can do, looks like I just have to accept this brand new brick lol.
Anybody know anywhere in London that does repairs like this, I have tried a couple of shops in London Victoria near work but they couldn't do anything. Apparently theres something called an octoplus/octopus box that can fix LG G2 imei or flash firmware.
Thanks again for everyones suggestions. .
Jon-jay, I have the same issue. I tried the "easy" kdz flash and tot flash and basically bricked my phone. The phone turns on but the screen is calibrated incorrectly like you describe so I can't click anything without trying over and over. I click one area of the screen and another is activated. I can pull down the notification pane but can't click anything in there. The phone is in a boot loop too if I don't touch it. I also want to turn on USB debugging so I could try to restore with adb or fastboot. I will let you know if I find anything.
Yeah very tricky to fix this phone after flashing. Ive flashed loads of lg phones with the flash tool and never any problems until now. Ive currently sent to a shop in south wimbledon who quoted me £50-£80 for repair if he could fix it. I dropped it off on mon and still no response so im not holding my breath. It seems this phone will be going to the recyclers if he cant do anything.:crying:

Check out the thread lg g2 is unbrickable now, it involves shorting a couple capacitors to unbrick but its ingeneious. I bet itll help you out.

the plot gets thicker...
okay so it has been a few months now and I revisited the phone sitting around. This is how I got on:
I gave the phone to shops in London, no-one could fix it got it back first week of Jan. So I thought I'd retry myself.
One guy told me that the imei may be for D802 but the screen and insides of the phone is a d800 model.
That makes sense as the touch works erratically. This was a refurbished phone I bought from aliexpress which claimed to be a EUR D802 but after I took the back cover off it says D800\d801\d803 inside on a lot of the flex connections and at the bottom of the plastic it says d800. I downloaded the AT&T stock rom and flashed with octoplus - touch worked perfectly! but phone kept restarting itself and looping really badly so I put in download mode and went back to D802 uk firmware - and touch not working again.
(Prior to this I bought the octopus box also in the hopes that restoring the imei I had previously lost will somehow be related to the screen.
This worked in restoring imei only and I have restored the d802 imei with octopus box)
Anyhow I then flashed stock uk firmware on the phone so everything in the phone works perfectly fine except the touch! so I am controlling touch with otg cable and mouse.
my next thought was install a d800 custom rom it will fix the touch! Now I then rooted, and installed d802 autorec.apk. I came on xda and downloaded a d800 stock custom rom (D80020k) from the AT&T subsection and thought I'd install this through twrp. All though the custom rom says successful when I reboot it comes to fastboot mode again. so I then go about restoring the stock d802 firmware. I installed d800 autorec.apk but that too send to fastboot mode.
So I am lost. Everything working perfect except the touch. Any ideas anyone? Im hoping some one says there is a stock lg custom rom that has all the screen settings for d800/01/02/03 which will sort my problem!
What it seems is the chinese company selling the refurb has somehow managed to get a d802 imei on a d800/01/03 not entirely sure how this is possible either!

What they're doing is flashing a d802 system.img with otherwise d800/01/03 firmware.
I saw a thread in the T-Mobile G2 area saying to get d802 on your d800/d801 you just flash a custom d802 rom and then a d800/801 kernel but this causes my phone to go back to fastboot...still lost! the custom rom works fine itself (Except for touch again!)

There is a way to get them back to their original frankenphone state but it's quite a procedure. Flash d802 firmware. Use a otg usb mouse to navigate since it'll have touch issues. Root and install custom recovery using the actual hardware as your guide to which twrp version to install. D800 in your case. Do a nandroid backup. Move the nand backup to your pc for safe keeping. Now install d800 firmware using a hex edited tot to allow it to proceed and a generic dll to avoid cross dll issue. Root, install twrp again. Move twrp backup from pc to phone. Do a restore but only restore the system.img. Now you have firmware that cooperates with d800 hardware while appearing and acting like a d802 in every other way.
The other thought I had but have not tested yet would be to flash d800 firmware right off the bat, then root and install twrp. Then use dd to flash system.img to it's partition ( /dev/block/mmcblk0p34 ). I'm not sure how that would work due to the very large size of the system image. You'd have to extract it from the kdz. Because it's so large when it's extracted, it does it in parts so it must be merged back together to make one file. But if it did work, it'd save the step of having to root/recovery twice on two separate firmwares.
So earlier today i received my phone back from repair, they replace the mobo. All seems good, phone works. So i unlocked the phone following this guide, same as last time: https://forum.xda-developers.com/lg-g6/how-to/official-lg-g6-bootloader-unlock-t3614719
It's a H870 and everything went fine. twrp boots fine, LG's USB drivers are installed and windows detects the phone fine. I wiped the phone entering "yes" trying to install fulmics. That didn't work as it bootlooped, so i went back re-wiped the phone.
I then tried to transfer stock [ROM][H870][Stock] OPEN EU LG-H870 10T ROM. It transfers 1.8gb of the 2.5gb before stalling, not getting any further and transfer eventually fails.
Right now i'm trying to transfer the LOS rom, but nope. Not getting any % and 5 min later the transfer fails.
I can enter bootloader and i can enter twrp.
So right now i'm guessing it's bricked. Searching the forums finds some users using something called uppercut but information seems very limited. Not sure what to do or how to do it.
Edit: So this is still a new phone to me, loads of stuff i don't know. So what i've done so far is using this unbrick guide http://www.android.gs/how-to-unbrick-the-lg-g6/
And i'm now loading H87010d_00_OPEN_EU_OP_0327.kdz through LGUP, and it appears to be working.
Hi all. Trying to recover my fathers old phone here and stuck in the firmware update do not unplug usb connection until process is complete, but has been stuck at 0%.
Back years ago, he was trying to do a regular install of an update from AT&T, something happened, and got stuck in the bootloop. AT&T didnt want to help and sold him a new phone.
We got into a fierce argument about the phone, if it can be fixed or at least traded in. Well, he died two weeks ago, and now I am trying to work with that phone, get it working, then trade it in, along with his S9+ for a newer model.
Any suggestions. Was never rooted. I can get to download mode, but nothing happens after that.

We are kinda stuck because there is no firmware for the H910 no kdz file you can flash. You can try a factory reset on the phone.
How to factory reset the Lgv20
This will wipe all data on the phone. Let me know if that works.
