Hi,
I went back to stock by using LG Mobile Support Tool application (Repair Software section). It flashed correctly (D802TR20c) and I started to use it.
After a while I wanted to install 20f kdz version via Flashtool. I booted phone to download mode, connected to PC. It starts upgrading but fails at %4. There was nothing moved on phone screen, it's still says samethings. COM port should wrote on phone screen when flashing started but it doesn't.
I tried repair software section on LG Mobile Support Tool, It downloaded right firmware for my phone and started to upgrading but it fails at %4 too.
I tried TOT flashing, I did it before succesfully. But now, when I press start button, it stucks at READY.
Then I downgraded bootloader and download mode via AutoREC application, but I have still same problem. I tried it other computers too.
I can still boot to recovery and system without any problem. I can boot to download mode too, but there's something blocking flash progress.
What I should do?
Thanks in advance.
I'm still stuck. It seems that nobody encountered with this problem.
If I'll solve this, I'll write the solution.

Hello guys,
I searched on the net but didn't find any answers. I'll try to be clear : Today I flashed my international G2 with the LG flash tool. Everything worked fine. Then, when I tried to put a new rom on the phone (by using a custom recovery), I made a mistake and soft-bricked the LG. Now I can still access to the download mode, but the tool doesn't work anymore when i plug the phone in download mode. I tried to reinstall the drivers, but my computer doesn't seem to see anything...
What's wrong ?
Precision : At each time, my phone was rooted, but this morning when I succeed, nothing was written in the download mode and now, I see the word "rooted" in the bottom of the screen.
HI There ! I own a LG F320L for sometime now. It came with Kitkat 4.4.2 installed and then i flashed it with CloudyG2 rom and have been using it ever since. For the past 1 month I have this strange touch screen issue with erratic behaviour and phantom touches. It has been addressed as software related issue and going back to stock has fixed some of the users problem.
Now to the main issue, I followed the tutorial of LG FLASH TOOL Method upto the point. Installed drivers and have downloaded the KDZ for stock kitkat but when I enter the download mode and LG flash tool begins to start it doesnt even verify my phone. It keeps stopping at 2% software extraction (sometimes 4%) and then a dialog appears saying Disconnect phone and remove battery and then again put the battery in and connect your phone and try. I have been trying it for many hours but it doesnt make any difference. I have used unrooter tool to unroot my phone for download mode. I have also tried the TOT method for going back to stock but no success. Whenever I plug in my device it appears in device manager but it is not recognized by FLash tool still. Please help me. I have TWRP 2.8.4.0 Recovery installed.
I am running windows 8.1 X64. The drivers install with no problem.
P.S I have searched all the threads regarding flash tool problems and download mode recognition. I didnt find anything helpful.
Hello,
I want upgrade my LG G2 with a new rom 5.xX
This phone have only the operator update. No custom, no trwp, nothing...
I installed drivers and when i want access to download mode. I can't. I use the good proccess with vol up then plug usb cable always with vol up presses.
follow this procces after a little moment my phone show me battery logo charging.
So i can't access to download mode.
I would use this process
t was NOT bricked. I finally tried playing around with the LG Mobile Support Tool (B2CAppSetup.exe). Of course it detected that my phone already had the latest firmware from T-Mobile, but then I clicked Options>Upgrade Recovery.
It downloaded for a while then I noticed it had put my phone into download mode (it said "Rooted" in red letters at the bottom). Then it flashed the same firmware over and I immediately tested, it entered download mode right away. But I didn't end up needing that as Stumproot was able to brute force it now after the recovery flash.
Anyway, I couldn't find an answer anywhere else. Most results also have a bricked phone, but that wasn't my issue. This solved my problem and maybe it could work for others.
but it's impossible for me to install B2appsetup on my pc the installation begin then stop after 5s then nothing.
I have Win 10.
Do you have a solution for me , please??

Hello everyone.
I have a D802 LG G2 16GB version.
I had on my D802 a BlissPop rom version 5.1 and it was frequently rebooting and sometimes when charging screen wont turn on and after rebooting it will say optimising apps.
I downloaded the latest Cyanogenmod rom for it and installed it from recovery.
The installation went quick and no errors, I then rebooted it.
It showed the LG logo for a second then only the back lighting was on.
I tried connecting it to the pc and it showed 12 drives all empty and with errors except one that had a folder called image.
It wasn't useful, so I tried the emergency mode and it worked - the PC detected LG and installed drivers althrough the memory is not detected.
At the device manager it detects LGE AndroindNet USB Serial Port and on the screen of the phone it says Firmware Update 0% and in small B60 ROOTED.
I will really appreciate any help regarding this, ofcourse I would like to find a way to fix it and get it back running if its possible?
Thank you!
EDIT:
I guess a possible solution is flashing a KDZ, but I'm not sure what KDZ I need for this. I have another identical G2 phone,how can I check using it what KDZ I need for it?(Which variant etc)
Update: Because of the problems with booting I automaticlly assumed that recovery mode is not an option but.. it works and I sucseesfully entered it. (!!)
I downloaded this rom http://forum.xda-developers.com/lg-g2/development-d802/rom-cyanogenmod-13-0-t3250514 (different from the one I installed before)
Then I wiped factory reset, dalvik cache and installed it, again installation went smooth.
After I hit reboot same problem, LG logo shows up for a second (quicker than usual, normal working LG) and then black screen with backlighting on.

have you tried hybrid bootstacks? install reboot recovery to recovery... flash rom and gapps ..?
if not use TOT methos.. or kdz. am not sure wich one ...
Problem fixed, the solution for me (It might be different for you if you're facing similar problem) was to download kdz and lg flash tool and reflash it to the original stock.
Hi,
I'm opening a thread because I just couldn't find any way to unbrick my device. In the past I used the FlashTool2014 to go back to the stock LP KDZ for my device.
I was in the stock rom when I decided to mess with the build.prop and then went back to the stock backup. When I restarted the phone it showed the LG logo, screen went black and never booted android. I could access the stock recovery but the Factory Reset won't work.
Then I decided to go to download mode, it connects and the PC detects it as an MTP device. I open the FlashTool2014 and it detects the device OK. When the LGUserCSTool opens it says the Upgrade stopped due to an error and the device stays on 0% and shows USER B70 in the console. I can press Retry, turn off the phone and reconnect in Download mode but the LGCSTool just wont push the firmware.
I suspected I had a driver issue so I tried using a clean win8 install I have for this purposes without success. I cant flash with the TOT method since the other LG Flash Tool wont detect the device in download mode when connected to the pc. This is really weird.
Any ideas ?
Thanks in advance.
EDIT: Solved with another tot file (almost lost all hope), took me 20+ hours to download it, I'll better make a backup of this files on the cloud. Still having problems with STOCK firmwares but could install TWRP and get CM13 which doesn't give any problems.
