Hello! Sorry for my bad language, but English is not my native language.
I have a LG G6 H870 EU. A year ago I unlocked the bootloader, installed TWRP and a custom rom.
Everything worked, but I bought a newer phone. Now I need LG G6 with original firmware (and stock camera app). I found the stock software on XDA for TWRP. I installed them. The phone booted up properly, Android requested data formatting. When I agreed, my phone got stuck in the TWRP loop.
Now I install various software, custom and stock - only TWRP starts every time. I tried LG UP but at 9% it shows "USB Connection established" error. I've tried various DLLs, but on others the program doesn't start at all. Maybe I have the wrong DLL? I've tried UPPERCUT too.
Please help, thank you.
Hi. I have a similar problem on my LG G6. After selecting reboot from TWRP, the message "No OS Installed!" shows. After reboot I get into TWRP again.
Using LGUP CMD (command line) I was finally able to flash the phone and get it working.

Sorry for the post hijack, just curious. How did you manage to unlock your bootloader a year ago. I thought LG stopped providing the unlock.bin's like, 5 years ago?

Hi,
first of all, thanks for reading this thread.
My problem is the following:
I rooted my device and wanted to flash a CWM over the Rom Manager and got a Success Message. The custom recovery apperantly didn't work. Now I am stucked in the Firmware Update Screen (no fastboot, no ADB, no reboot)
I looked up the "General" many different options including this thread http://forum.xda-developers.com/showthread.php?t=2582142, but I couldn't find any files for my specific model. Can anybody provide me those.
I had the Software D80220H
I tried the LG Mobile Support with the stock reset as well as the LG Flash tool 2014 with the corresponding files from here. All these options stopped working between 33% and 40%. The LG Flash Tools (for .dz Files) doesn't recognize my device at all
Does anybody can provide help ?
Thanks in advantage.
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?
Hi i am new in the forum and have a issue with my LG V20 F800k. That what is on back of him( under battery)

I try to flash stock rom with LGUP, but with no success.I go to bootload mode on phone,.First LGUP asked me .dll for H918. Found it . Put him in common folder in LGUP, but when i want to flash stock rom (upgrade bottton in lgup) process start, but after 17 seconds i got an error in setup (click herer to continue) . When i press again display me command port error-3
Can someone help me with flashing stock rom?
Thanks
Hi,
my H910 is not starting Android anymore.
I flashed many KDZ Files (different versions) with LGUP:
First in the mode "partition DL" (selected all partitions), after that I tried it often with "Upgrade" option.
Everything seems to be succesful, but LG V20 is in boot loop at the LG logo.
Sometimes I can see after LG Logo a circle with "erasing" for some miliseconds.
Tried recovery factory reset, circle spins some seconds then reboot and same loop.
Download Mode always works.
Factory reset dialog (recovery) works, but erase progress seems not to work.
I don't know what I should try now anymore.
EDIT:
Downloaded newest LG Universal Mobile Drivers from LG Site and now everything works
For the sake of leaving a record what helped you out of your problem, could you clarify?
You downloaded the latest LG Universal Mobile Drivers from LG site and installed them to your PC, replacing the drivers that seemed to work (the device was visible, LGUP did not complain).
Then you used the LGUP again to load something and that fixed the bootloop. What was that thing you loaded after updating the drivers?

Hi,
yes new drivers from LG site was my solution.
It was correct visible on LGUP before too.
Now I flashed same as before firmware 10f, than dirtysanta root and than recovery. As written in that "How to root" threads.
Seems like old LG drivers hat maybe some problems with Win 10 so that not everything was written correctly.
