[Verizon LG G3] annoyingduck:
-For reference, here's [MENTION=5171089]ins5736[/MENTION] thread for restoring using the .tot method: http://xdaforums.com/verizon-lg-g3/general/restore-verizon-to-stock-t2827878 .

-Also there are reports of the tool deleting the KDZ you copied to the Flash Tool folder after the flash. I cannot confirm this, as it did not happen to me, but to be safe make sure you copy the file to the folder instead of pasting it so that you don't have to re-download the file for future use.

-Please note that the KDZ file we have is build # 10B.01, while the .tot file available is build # 10b.03. The only difference between the 2 files is that the .03 build is the actual released build that shipped with the phone, while the .01 kdz build was obviously a pre-released build. Its most likely some minor last minute changes/bloat added. We can't find any noticeable differences between the 2 builds.

-OTA's WILL FAIL USING THE 10b KDZ FILE WE HAVE due to a signing error with it being a pre-release. The purpose here is to downgrade, unlock, and flash whatever you want. This is NOT to return to an official stock state. You'll need to use the .tot file or the official LG Flash Tool that downloads the current build automatically in order to be in an official "stock" state. The 12b kdz is official and will allow OTA's

*Error Update* So with this leaked LP image, I've been playing with kdz'ing quite a bit and with a new Windows install I got to experience a few of the issues being reported by others that I have never seen, along with trying to troubleshoot some others. Did I manage to fix them easily you ask?? Hell yeah!

USB Disconnected Issue: This is a driver issue. Very easy fix, just download the latest Verizon drivers from the link I posted above and install them without phone plugged in. Power off phone, hold up, plug into usb and WAIT for download mode drivers to install (as stated several times in this thread). Click the balloon to watch the progress, this took about 10min on an i5/ssd machine - be patient. This is the predominant issue I think people are having. The drivers while in download mode are:

-USB Composite Device

-LGE Android phone or LGE AndroidNet for VZW USB Serial Port COM5 (this is the important one)

-CDC Serial or LGE AndroidNet for VZW USB Modem (this will fail if you are on a rom with certain VZW items removed - not a problem, its not needed)

-CDC ECM LGE AndroidNet for VZW NDIS Ethernet Adapter

If driver install fails, manually update them by pointing windows to the driver file you downloaded. I am not going any further here, use Google.

??????'s In The Field: easy, don't change region or language from Korean as stated in the OP. Leave it alone, it will flash in English I promise you. Result = all fields readable in English while running

Connection To Server Failed: Simple, ignore the window. Just drag it away, but don't close it. This is an offline hack originally indented to run online, deal with the window!

Progress Bar: The tool will initially analyze the phone, then when flashing starts, pay attention to the phone screen which will now say COM5. The blue progress bar on the phone is the important one. At around 80% on the tool screen, the phone will reboot. The flash is over and the bar will continue to progress into the 99% while rebooting - then the program will crash. You can disconnect now, you've been successful.
