Hi evryone.

Recently I came across this guide, and it worked fine for me.
So I wrote a tool that basically does the same thing, just make things easier.
This method should work on any LG G3 official firmware (4.x.x / 5.x.x), and on other models too.

Please leave your feedback if it worked for you, and indicate whether you used the graphical user interface or the old script.
And if it's didn't worked, please attach here the log from the window.


Notes
  • I saw a lot of questions of G3 users about how to install Twrp after the root, so I will explain briefly:
    For now, if you are on stock lollipop you can't just flash Twrp via flashify etc like the old days in KitKat, but you can follow this guide over here.

  • After the root, if you want for some reason (warranty etc) to unroot the phone, all you need to do is a full unroot from the SuperSU settings.
    I don't know if this is enough to get OTA updates back, I'm still waiting for somebody else to answer this question. so please don't ask me about this any more because I really don't know the answer.


Devices confirmed working with this method (If your device isn't listed it's most likely still supported)
  • LG G3 (all variants)
  • LG G3 Beat
  • LG G2
  • LG G2 Mini
  • LG G Pro 2
  • LG G Pad

Changelist:
LG One Click Root v1.3 - 13/04/15 (current)
A new version with a graphical user interface instead of a script.
Although the root process remains the same, it has been rewritten programmatically, so I hope it will solve problems on some devices.

LG One Click Root v1.2 - 23/03/15
Added instruction in the script to how enter download mode manually if needed.

LG One Click Root v1.1 - 22/03/15
Added support for Verizon users.

LG One Click Root v1.0 - 17/03/15
First version.

So is this taken care of already in this root method. Will I have fast boot and laf after root?

What do I have worry about having an unsecured boot loader. What approach should I take for having root+fastboot+laf.

    I've got over 2.5GB free on internal storage, and about 14.9GB free on the SD card. Should be plenty of elbow room for the rooting process, as long as the card can be accessed in Download mode. If it can't, I could free up another 1GB by dumping apps, but the unzipped size of SuperSU is only 3.9 MEG. How much room does it need, to unzip??
    Click to expand...
    Click to collapse

    IF you are getting to 90% in download mode and its "freezing" wait........ maybe 3 mins........ and Just pull the usb from phone.
    YES while its stuck in download mode @ 90 % , wait three minutes and pull the usb from phone,
    count to 3
    power off
    count to 3
    power on
    android should upgrade ( install SU ! )

    At the begin, in the popup window "Allow USB debugging?" did you checked the option "Always allow from this computer" before you click OK?
    If not, please try again, and this time you check this option.

    The thing is after the reboot (normal reboot), the script waiting again for ADB connection to be sure the phone is detected on the computer, before reboot into Download mode.
    The reason I had to do this normal reboot first, is because otherwise the files (previously pushed) my not saved properly.


    Just do "full unroot" in SuperSU settings, or flash full firmware again without wipe (normal flash, not cse) via LG Flash tool 2014.
    Click to expand...
    Click to collapse

    It worked now. I had already checked the "Always allow from this computer?", but the script was still waiting. What I did now was to unplug the phone from the USB, when the script "Looking for LG serial port...", and plugged it in another USB port. Then the script followed the installation normally.
    Anyway, thanks for help!
