How to Root LG G3!

Thanks to Open Source developers, we have full root method for the LG G3!

There’s currently many root methods for the LG G3, this is one of those methods.

Now, this is the ONLY root method for those of you who T-Mobile LG G3 but also works for many others.

UPDATE: These root instructions are for KitKat ONLY!  If you have Lollipop, you can follow the guide here on How to Root LG G Flex 2, G2, and G3!

Today, we will be using PurpleDrake root method to root the LG G3.  There’s two ways to use PurpleDrake, you can either grab the scripts on XDA OR you can also do it manually.

Since at the time of this post they don’t have a script for Windows yet, I will be showing you how to do it manually using PurpleDrake asset files.

Please don’t forget to donate to the developers of this root method!  You can donate here.

This root method should take you around 15 minutes at most so let’s do this!

Step 1. Go to Settings->General->About Phone->Software information.

Check your Android version, this root method will work on Android 4.4.2.

And also check your Build number, note the last 3 characters and make sure it’s listed here:

  • AT&T LG G3 D850 w/ Build number 10D
  • T-Mobile LG G3 D851 w/ Build number 10C
  • Korean LG G3 F400L, F400S, F400K w/ Build number 10A or 10B
  • OPEN LG G3 D855 w/ Build number 10F or 10G
  • European LG G3 D855 w/ Build number 10A

For Verizon LG G3 VS985, you can use IORoot.

    Hey as far as the Linux part goes I already have the tools installed do I really need to do the ./adb-linux? Just curious because in rooting my nexus 5 I didn’t…

  2. Lagnis says:

    Awesome! Nice job,

  3. Jean says:

    I did Towelroot on my AT&T G3; took seconds once the apk was downloaded…easiest root ever, not that I don’t appreciate the details above, but if it can be done so simply, why not?!

    • Max Lee says:

      I do recommend Towelroot but it doesn’t work for all G3 such as T-Mobile LG G3.

      • philip says:

        I tried towelroot but when I click the button it tells me that my phone is currently not supported. I also have an G3 through AT&T. Any advice?

        • Drew says:

          I have also tried to use towelroot with the D850 AT&T G3 without sucess. I believe if you have upgraded from the firmware 10D to the 10F release, it stops towelroot from working correctly. Try using Stump Root instead. A little more work but it gets the job done.

    I have been following you a long time ago, since my Galaxy S2. Excellent work. Keep on High on Android.

    May I ask if you are going to cover the Samsung Galaxy Tab Pro 12.2 SM T900 ???
    I liked it so much because I can easily read PDF magazines and PDF books without eye fatigue. The size of a legal paper.

    Planing to buy the LG G3 because the A) memory B) audio quality C) Camera. On the camera the G3 lacks the flexibility of adjustment of the stock samsung camera. Hope some custom ROM fix that.

    Joe

    • Max Lee says:

      Hmmm I may think about the Pro 12.2, looks like a really nice tablet. G3 camera is awesome, but you can always install Google Camera also to tweak a bit.

  12. Michael says:

    Hi Max, I cannot get my phone to get out of offline status, despite having USB debugging active, can you help?
    Michael – Always High….(on Android)

  13. Grace says:

    Hello~ T-Mobile D851 user here

    So everything was going fine until I did adb devices and instead of offline I got unauthorized?

    Also, I got a “cannot stat ‘start_restore’: No such file or directory”

    Help please!

  14. Coco says:

    Dear Lee,
    I was following your instructions to root my G3, but accidentally I unroot it, so I try to repeat those steps again, it works fine. But when I reinstall the SuperSU from the Play store, error message pops up “There is no SU binary installed, and SuperSU cannot install it” What should I do now? Could I reinstall the SU binary manually? If yes, how to do so? Thanks, and look forward to your reply!

  15. Hello Max,
    After I rooted My G3, it’s keep saying:
    “Unfortunately, the process com.android.systemui has stopped”
    every 1 sec. and can’t go on nor progress to settings or anything.
    Do you know what I should do to not see that message?
    Always appreciated for your effort and your revert to the World~

    Thank you

    Rj Ro

  16. philip says:

    after rooting now I get “unfortunately the process com.google.process.gapps has stopped” google hasn’t helped… any ideas?

    • A says:

      Had the same problem, just uninstall Google Keyboard and restart – that should fix the problem, you can reinstall it afterwards, no problem

  17. Paul says:

    Hey Max,

    I used your sites when I rooted my Galaxy S4. When I got my new LG G3, immediately thought of you as my goto guy. I looked at your How to root video and everything looks straight forward. However, I am from Canada on the Rogers network and I do not see my model LG D852 or software version D85210B in the list of compatible models for your root method. Will the present root method work with my phone or do I have wait until you post a compatible method for Canadian variants?

    Please let me know,

    Thank you for time.

    Paul

Grateful for any ideas as lots of things disabled with Chinese build.

The window asking for allow USB debugging for this computer never comes up. I have tried restarting the adb server and also deleteing my computer’s RSA key. If you could help me that would he great.

  47. William says:

    Hi, I have a LG G3, european version as I live in Sweden, which has:
    Modelnr: LG-D855
    Android-version: 5.0
    Kernel-version: 3.4.0
    Versionsnr: LRX21R.A1419207951
    Softwareversion: V20f-EUR-XX

    My computer is a Macbook Pro mid 2012, 16gb memory, 1tb harddisk, OSx 10.10.1
    My question is: How do I get the LG G3 connected to my mac via USB?
    I have tried all kinds of drivers from:

    (MAC)LGUnitedMobile_Mac_Driver_Ver_4.17
    (MAC)LGUnitedMobile_Mac_Driver_Ver_4-2.17
    (MAC)LGUnitedMobile_Mac_Driver_Ver_4-3.17
    (MAC)LGUnitedMobile_Mac_Driver_Ver_4-4.17

    I have installed LGPCSuite and when I run that it cannot see my LG G3 that is connected via USB.
    If I try Wifi, then I see my phone and can copy music to it.
    I’m assuming that I need the USB connection because I had copied music via LGPCSuite to my
    phone storage and not to the SD-card that I really wanted to. When I try to remove that music, it
    says I’m not rooted so I assume that if I want to root the phone I would need USB connection.
    I have tried the adb-mac devices command but it shows no devices. When I connected the phone
    via USB I get the 3 options where MTP and PTP seem to be the only options. Tried both but phone
    is still not recognized. Any ideas? /William

  48. Neal says:

    I got the same problem, I got the upgrade from T-Mobile and lost the rook and got the same msg as everyone else got. There is No SU binary installed and Supersu cannont install it. So I see that no one has answered anyone’s help on this one.
    Can someone answer our cry for help?

    Max,

    If I take the OTA on my G3, will I be able to keep re-root after installing the update? I’m on 10B stock firmware. I’m rooted on stock firmware. I haven’t been able to find any custom roms based on stock firmware except SkyDragon. I keep having problems with lag and hanging. Also, SD Card keeps unmounting itself. Any suggestions? Thanks much!

  59. Fred says:

    I’ve tried using both the purpledrake script and the manual instructions listed above, I can’t seem to root my device, which is a T-Mobile D851. My computer sees the phone and executes the first command to temp root and then It reboots into what looks like a recovery. With the options to reboot, wipe cache, wipe dalvik, install from adb sideload or install from sdcard side load. I also have an icon of the “dead” android, which has “no command” below that. Any help will be most appreciated.

  65. J says:

    Guys give it up. Max hasn’t commented on this forum in over 6 months and probably never will again. No there is no root for the G3 with 10r software and no one really cares about making one. Its been this way for almost 5 months.Get over it and move on.

  66. Ben says:

    I’ve LG G3 Tmobile, model android 4.4.2, sf version D85110r, kernel 3.4.0 – I pretty much followed your steps all the way up until SuperSu.

    I reverted to 4.4.2 in order to root my lg g3 t-mobile.

    Alas, it is 10r not 10c, but i thought i would try it anyway.

    It never gives me the page for approving debugging. Is this what the patch does or

    is there some way around that? Thanks
