LG Flash Tool "Failed Previous Load()" - Verizon LG G3

Hello,
I am trying to restore my Verizon LG G3 (model VS985) to Kitkat (android version 4.4.2) as the new lollipop OTA upgrade from a few days ago is terrible.
I have followed this guide to using LG Flashtool to the letter but LG Flashtool (version 1.8.1.1023) is not working. I'd post a link to the guide i used but do to being a new user the system wont let me.
When I click the arrow everything goes well until the BIN CRC Check, then I get an error that says "Failed Previous Load()"
I double checked to make sure I downloaded the right .tot and .dll file for my phone.
Any help at all would be greatly appreciated! Thanks!

I'm having the exact same problem you were, same VZ model as well. Have you by any chance found a fix for it?

Have you tried a different version of the LG FlashTool? I'm using v1.8.6.527 and haven't had any issues. Everything looks correct based off of your screenshots.
You copied the MegaLock.dll you downloaded to the LGFlashTool folder? (C:\LG\LGFlashTool)
I renamed the one that was originally here by putting a .orig on the end, the took the downloaded MegaLock.dll and put it in that location.
I attached a file here with the version of the LGFlashTool setup.exe for the version I mentioned above, and it has the MegaLock.dll too.

Are there steps to setting this version of the flash tool up? In addition where do you get the vbs file?

Personally I find the kdz method easier. I also seem to have less problems if I right click lg flashtool and run as administrator.
Sent from my VS985 4G using XDA Free mobile app

I had the same problem , bweN diorD posted drivers for me to use in this thread, I can't upload files, but look for his post or mine about "need help returning to stock", his drivers did the trick for me. Be sure to unistall drivers you have on your pc before loading his, hope this helps you, credit goes to bweN diorD
Can't link to thread for some reason, but title is "please help hung up in downgrade to 10b" , driver link is in thread

Nope. I haven't had a LG phone for over one year now.
