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,
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,
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??

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.

Try this one, it worked for me, seems dangerous, but it seems like you have corrupted qhsusb

Whis will allow you to enter to download mode, then you can use the lg flash tool.

Try nuking download mode and then entering it. If it doesn't work, try the unbrick.
By the way, using capital letters doesn't hurt.
Hello guys,
So I bricked my D802 , how? first it was bricked because of a wrong version of TWRP, untill here no problem, i tried many tutorials on how to go back to stock rom, then i found that it was a Qualcom thing problem, so I found that tutorial about replacing the .img files etc... , pretty easy, i could enter the recovery menu, but it had no rom, i downloaded the stock rom kdz file , started flashing it, then, for some dumb reason the flashing stopped, I ... plug out the usb cable... I didn't notice untill I saw that the program froze, and now the phone is stuck at the LG logo, impossible to do anything, pc doesn't recognize it, can't go to recovery menu, can someone help me please? or at least tell me if I should just throw that phone or keep it if it has a chance of living a bit longer

I had a very similar problem with it getting stuck at the logo after pushing supersu to the phone. I followed Supersport every single step of the way in his video. I think his links are the only valid ones online now, so just download them and reflash your phone. If your G2 is anything like mine, drivers will never appear to be installed correctly and it never restarts, only shuts down.
His method is:
1) Download and install LG drivers on PC
2) Download and install the flash tool and patch it
3) Download and load the .tot and .dll files into the flash tool
4) Enter download mode on G2 by holding volume up while connecting USB
5) Switch G2 Com port to 41 in device manager
6) Once Flash tool shows that all ports are ready, power down G2 and disconnect
7) Hold volume up and reconnect to get back into download mode
8) LG Flash tool starts flashing
9) Complete
Note: If your G2 was screwed up as bad as mine, it'll say failed but all the main system files will load to the device before it restarts and it'll even shut itself off while doing it's installation on first reboot. Mine somehow was still revived from this state with his method.
