[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.

I bought an F400L, but it seems that the Honk Kong shop I bought it from has flashed it with a F400K rom (presumably because it has less bloatware), I am a noob and am wondering if they had to root it to do this (and how do I find out if my phone is still rooted) and if I will still be able to do an official over the air update when LG releases one?

Hi, I'm in the same boat, also bought from a HK ebay store. The 400L came with 400K rom and now I can't update it...which shop did you buy from?

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

I admire your patience. I used your guide with my G2. Same questions day after day.......

By the way, I'm now using windows 9, how do I get this to work? :D

Hi, I may just be having a brain fart, but I get lost when I get to these steps:

10) MAKE SURE UNDER, DEVICE MANAGER, YOUR PORT IS SET TO COM 41 FOR YOUR DEVICE.

11) Click the DLL box and choose the dll file from above for you phone model.

10) I'm assuming the device manager is the window underneath the flash tool window? If so, I can't access that window until I'm done with the one on top (the Select Manual Mode window).

11) Since this is a KDZ file, what are the appropriate steps?

Thank you!

    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.

    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
