Let's try and complete this tool, you should be able to flash the entire bin with the lgflashtool.
Download a kdz and this zip https://mega.co.nz/#!sldDFRZD!7jV2t2eIku90gEmxxi7-SIrqiHFvNg7KD0gR6Soxdzo

Place the kdz in the extracted folder and run the extraction batch script.
This script combines the bins in the proper order, so hopefully you won't need to use the offline flash anymore.

Uninstall all lg stuff in uninstall program. Also delete C:\ProgramData\LGMOBILEAX folder.
Make the changes to the host file and reboot. I use apache instead of shttps.exe program.

More info, the lgmobile tool also adds a script that checks for updates at every boot (Startup), so disable it.
open msconfig > Startup and disable any lg stuff.

Hi ELCID777, you could try kuma82's last modification from [BIN]{LGFlashTool} Unbrick/Unroot/Flash ANY (P769, MS769, P760) in Download Mode
It works fine for me with W7 64 bits.
Cheers. Good luck.

Hi, do you think you could make a video tutorial showing step-by-step how this is supposed to be done? It's a bit difficult to follow your written instructions.

---------- Post added at 06:44 PM ---------- Previous post was at 05:56 PM ----------

Um, yeah. Just tried doing this, and it's nearly impossible, or very difficult to follow your instructions. Please, if you can, make a YouTube video outlining everything step-by-step, it would be a lot easier to understand that way.

i sent pm to him :fingers-crossed:
