[Q] Only Fireware Update Screen Appears - G2 Q&A, Help & Troubleshooting

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.

[Q] L7 P700 KDZ Flash error Wparam/Lparam

As stated in title:
- Updated to stock V20X (no root), then tried to flash V10k rooted/CWM/bootunlock etc.
- Can't flash through KDZ updater whatever the mode (DIAG/EMERGENCY) because of a Wparam/Lparam error every time
followed various tutorials to the letter, even with a downgrade solution but still no dice.
I usually end up with the yellow emergency screen as a semi-brick (have to use LG phone recovery method)
Not sure if if there's something I'm missing here, I'm used to the optimus 2x which never fails when flashing KDZ files.
Any help would be much appreciated! Thanks

Resolved: flashed the downgrade file and ended up with LG logo bootloop, looked a bit further into the issue; had to do a hard reset (which led me to see that CWM had actually been installed) - wiped/reset through CWM and boot finally worked.

[Q] Soft bricked D801 unrecognized

Hey everyone I'm quite new to android, and I'm currently stuck in Download Mode after trying and failing to install Twrp
I was previously Rooted, tried to install Twrp via Autorec, however when I ran the app it soft-bricked my phone and put me into Fastboot mode.
I followed http://forum.xda-developers.com/show....php?t=2476972 method, and got back to Download Mode.
I am currently in the middle of returning to stock through http://forum.xda-developers.com/show....php?t=2432476 using the .TOT method.
I'm fairly close to repairing it but my only issue is that I cannot get my computer to recognize my phone. Neither in Device management nor adb devices anymore.
Therefore I cannot change the port to COM 41 to flash the .TOT file.
I constantly tried installing drivers for the phone both 3.10 and 3.08 but still no recognition can anybody help?
Some more info about the phone:
it's the D801 variant but its on Wind (Canada) not T-mobile
it was previously Rooted
it did not have any recovery software installed
no roms had been flashed previously.

Try to restore your phone using the official LGMobile Support Tool. Just switch on normally the phone, plug it to your PC and wait for your kdz to be downloaded. Once it done, it should install the kdz by itself. Then factory reset your phone (if needed) as it should ask you some pin/password.
Hope it'll help you as it did for me!

Bricked LG G2, download mode goes on, but not working

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?

LG G6 - TWRP loop

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?
