I'm having an issue with LGUP.

I've done as instructed in OP #3
Install LGUP_8994_DLL first and then LGUP

But when I connect the phone, and run LGUP it says "There is no handset connected. Please, connect a handset(s)."

I've disabled USB Debugging, and the phone is in MTP mode, but and shows as "LGE Android MTP device" in Device Manager (having updated the driver).

Am I missing something?

So I read everything and followed everything the OP said and tried to restore my phone about 6-7 times with no avail. YES I FOLLOWED EVERYTHING. Both TOT and KDZ methods give errors and the only thing I caught on the TOT method is that the program isn't reading the phone's actual name which is vs985 but it is showing the BIN # and DLL # and fails after I reconnect the phone back to my usb because the start button just sits there. The KDZ method did install something but nothing boots up expect the android recovery droid and when I retry the KDZ method again the program gives an error "Upgrade stopped due to an error". To give my background..I came from RR Marshmallow on the vs985 and wanted to go back to stock because my recovery for some idiotic reason wouldn't boot. Anyways anyone have a solution or a link to a thread/post where I can restore back?

Edit: 10th time with the kdz method and it worked after I waited like 10mins. If anyone has a miniOS / Blue Screen Number 2 here's a link to that fix: http://forum.xda-developers.com/lg-g3/general/problem-returning-to-stock-try-t2862463

If you have the blue screen you use board_dl on the tot/dll selection screen. I've mentioned this several times here :)

I'm trying the tot method, but all I get when I get to step 14 (final step) is something about "NO KS version..." It errors out at 6%.

Anyone have any ideas?

Hi guys, when using the KDZ method in the 'Select Type' dropdown list do i always select CDMA?

My phone is a LG G3 32GB D855.... Is this not a GSM phone?

    [Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ & TOT Method With LGUP

    LGUP Video Guide - Thanks to @KiaTheKing !
    https://www.youtube.com/watch?v=iPKcuYwDoxY

    NEW LGUP Method. This one method can do BOTH TOT & KDZ!! Thanks To @shakeyabooti![/U][/B] Suggested use for the D855 ONLY! Other models use the previous methods.
    Notes: This method is REQUIRED for flashing MM KDZ files downgrade from MM or upgrade to MM you must use this new method. Old KDZ method you cannot downgrade from MM.

    Download Files - LGUP_LG_G3.zip - 16.9 Mb
    KDZ & TOT files Here - http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/

    This is the NEW KDZ Method for the LG G3!!! Thanks to @shakeyabooti !!

    NEW software!!!!!...... LGUP WILL FLASH YOUR KDZ files
    Download LGUP from here: http://oceanhost.eu/545euinlq0hw/LGUP_LG_G3.zip.htm
    Install LGUP_8994_DLL first and then LGUP
    Make sure you have downloaded the required KDZ file MM or LP
    Start LGUP prog on your computer "make sure your phone is plugged in"
    If you have a problem that LGUP does not see your LG G3, leave your mobile connected via USB and leave LGUP running, restart your mobile, hopefully this will solve the problem.

    TO UPGRADE TO MM from LP - make sure BIN file is ticked and in the File Path point it towards the MM KDZ you have downloaded. MAKE SURE YOU HAVE CLICKED UPGRADE! This will update you from LP to MM with out wiping any of your info. Press Start. Make cup of tea and be patient

    TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
    IMPORTANT!!!!!!! shut down LGUP!
    Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient

    TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a full wipe, tick BIN file. Press Start. Make cup of tea and be patient

    If you are worried about losing your data after a full wipe, why not use the LG Bridge software to backup and restore.... it works fine!
    YOU WILL LOSE ROOT!
    There is no need to enter download mode! LGUP will do it for you.

    flash tool link?
    thx
    In the OP I just haven't fixed the links but if you go to the G2 guide I made long ago the links are there and just follow the g2 guide. My g3 guide is pretty much the same as mg g2 guide you just use G3 firmwares
