How to Unroot/Unbrick LG G3!

For those of you who may soft-brick your LG G3 (soft-brick is when you are stuck in a bootloop), want to return your phone back for warranty, or simply want to return back to 100% stock, here’s a step-by-step tutorial you can use.

First, you will need a Windows computer as LG Flashtool program does not support other operating systems.  (You may be able to use VMWare on Mac or Linux, it should work.)  This should work on all Windows including Windows XP, Windows 7, Window 8, and Windows 8.1. (I am using Windows 7 64-bit, I just don’t like Windows 8 that much.)

By unrooting/unbricking your LG G3, YOU WILL LOSE EVERYTHING on the internal storage of your LG G3!  So, PLEASE MAKE A BACKUP of everything you need to backup before preceding!  (YOU’VE BEEN WARNED!!!!)

Step 1. How to get into Download Mode?

First power off your LG G3 or you can also pull the battery out then in.  Then while holding the Volume Up button down, plug in a micro-USB cable from your computer.

Step 2. You should see your phone showing “Download Mode”.

Then it should turn to “Firmware update” screen.

Step 3. Go to our LG G3 Stock Factory Firmware page and download appropriate firmware and DLL file for your LG G3.  (If you don’t see your model, try Googling it first.)

howto-unroot-unbrick-lgg3-4

Unzip the stock firmware zip file, you should get a folder with a file that end in .tot.  (You may have to enable hidden extensions on Windows to see .tot, if you don’t see the extension, don’t worry about it and go to the next step.)

    i need help… i keep on getting a number 2 and it keeps on saying USB PORT OPEN FAIL! please help me

    • Travis says:

      Ok redo the steps but make sure you you use a different usb port.

    • Benjamin Kuo says:

      Just wanna share my experience. I had the same problem, either I get to the last step and get a big ass “2” on the screen, or it fails at step 10, where the flash program says “failed to switch to download mode”. That happened with every all 3 USB port on my laptop.

      I then try another laptop and everything works! thank god for lgg3root.com!

    • Justin says:

      This happened to mine as well. I tried all 3 USB ports and nothing worked. I went into my device manager and un-installed my LG G3 from “other devices”. I put it back into the original USB port and restarted the process and it worked!

    • Jesse says:

      On step seven, switch from UPGRADE DL to BOARD DL

  2. Hello Max,

    Thx

  3. Marcelo says:

    i need help, i have the sam problem that gerard said, my lg g3 got stuck on Screen, blue and says Factory Reset Status 2

  4. Neil says:

    Hi Max. I had trouble flashing to the stock ROM after the OTA got me stuck in a bootloop. It failed. I tried to start it up. All i see is “Factory Reset Status” and the number 2…that’s after attempting your method twice. Please help, sir!

  5. james says:

    I need help for some reason my phone after booting up keeps going to TWRP. Even after pressing up on back of the phone it still keeps doing that

  6. Khoa says:

    Hi I need help with my LG G3. I dont know what the problem is but I am thinking that my phone is in bootloop but I have another problem, my led is blinking red and blue.. does anyone know what this is ? and how I fix it?

  7. Khaled says:

    hello,
    in step 10, it always stops and gives me ‘download failed’ message. ‘Can’t change to download mode’ it says..
    what should I do?

    • Beefsquatch says:

      Do not plug it into a usb3 port, usb2 only

      • Allen says:

        Mine does the exact same thing, after flashtool connects it says “can’t change to download mode” I know for 100% I’m plugged into a USB 2 port. Any other ideas? I really would love to get this done, pleas someone help

        • Benjamin says:

          Did you tried in win 7? meaby that’s the problem

        • Damion Miller says:

          I kept having the same problem. I updated to the latest LG drivers for Windows here: http://www.lg.com/us/support/software-manuals. I then tried process again and got to blue screen #2 and got “USB Port Open Failed”. Now I’m stuck. I think it’s a com port issue because now I closed LG Flash Tool and went to try again and the Com Port 41 shows to be in use when I try to change it in Device Manager. I’m stuck right now. I’m going to try to uninstall and reinstall Flash Tool and try again.

          • Damion Miller says:

            update: I ended up just changing the com port number to 41 and got a warning saying it could cause device in-op. It worked. I also changed the usb port on my computer. I think that is what did it. successfully flashed.

        • cyril says:

          right click port 41 and disable it. reenable it an it wii be perfect! 🙂

  10. Bryce says:

    Hi;

    I’m trying to unroot an LG G3 I bought on ebay that turned out to be a “demo unit”. I got up to the step where I need to download LG drivers for Windows, however I’ve downloaded and installed several times (both the regular and verizon drivers you posted) and I’m still not seeing the LGE Mobile Serial Port under my ports area. Any thoughts on this? It’s a verizon unit, model VS985. Thanks!

  11. Bryce says:

    Actually I figured it out, it ended up working. Thanks so much, you guys are awesome!

  12. JP says:

    I was able to figure it out on the 3rd try.

    In Step 7: I also switched to Board DL instead of Upgrade DL

    During Step 10: your phone will reboot to the AAT Screen – Click OK (Yes, it says not to), then hold down power and press normal boot (+power).

    Your phone will reboot and all should be well.

    • Ryan says:

      I have to say that I freaking love you for this. Thank you so much

    • Maykel says:

      I super love you dude, I was bugging out, followed the instructions like 5 times, switched ports and nothing but your option worked perfectly!
      Thank you so much
      Maykel

    • Seth says:

      Good call…I couldn’t get it to install correctly until following JP’s suggestion of switching to Board DL…but I also had to run the LG Flash Tool in compatibility mode (set for Windows 7). Once I did that, everything worked fine–completed using a MacBook Pro running Windows 8.1 on Parallels 10…

    • Nkosi says:

      I know this was a while ago, but I still just want to thank you. This solution worked perfectly…the second time. The first time I got a blue screen with 2, so I changed USB ports, tried again, and it all worked perfectly. You, sir, are amazing.

      This worked for me using Windows 8.1 on a Verizon LG G3, using the Verizon firmware files.

    • Tim says:

      Thank you so much, you are a life saver! You also most likely saved me hours of time. Much appreciated!

    • Ash says:

      Update from 2015: Yes this is the right way. Thank you so much. Saved my G3.

    Come On Man! Several of us are stuck with: “Factory Reset Status 2” USB PORT OPEN FAIL!
    Can anyone get past it? Please help.

  14. John says:

    YES! Thank You JP in this message board. You found the solution to the Factory Reset 2 problem!
    I followed his suggestion & it worked on my LS990 (Sprint G3)
    In Step 7: I also switched to Board DL instead of Upgrade DL

    During Step 10: your phone will reboot to the AAT Screen – Click OK (Yes, it says not to), then hold down power and press normal boot (+power).

  17. Jean says:

    My situation is much worse; I’m in TWRP, no OS (I must have wiped it completely while trying to reboot/reset), and at Step 9 (I changed to Board DL), it doesn’t start…

    Any suggestions? All because of the OTA from AT&T (I selected install, and it put me into TWRP bootloop).

    • Jean says:

      LG FlashTool won’t start…

    • Mike says:

      I have the same issue – ‘Can’t change to download mode’ it says. So, then unplugging the phone from USB I try to start the phone and I’m continuously brought back to TWRP no matter what I do. Anyone’s help would be appreciated. Thanks in advance.

    • Mike says:

      Found this on AndroidCentral: Saved my life – it got my phone back to original. Hope this helps others.
      *****************************************************************************************************************
      What worked for me was from the TWRP terminal command was to type

      dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

      then hit enter

      type

      dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

      then hit enter and reboot.

    Thanks you verry much

  20. drew says:

    I got stuck on the unable to download point, was using a laptop with usb3, swapped to laptop with usb2 and then went through same process. At the point where it says unplug for 3 seconds I tri3d this and it didnt work so did it all again but this time pulled the battery and restarted the phone…first time this method it got to 73 % and then said cant connect with phone….tri2d again and this timevworked perfectly. Took about 400 seconds..hope this helps

  21. Drewski says:

    Trying this has left me with some takeaways that might help others. I tried it multiple times on my Windows 8 machine with no love… Kept failing around 10% on the Flash Tool. I changed a couple factors: Used my Windows 7 Professional at work and used the stock usb cord that came with the phone. Can’t ultimately say which helped (prob the computer change) but it worked like a charm.

    Thanks so much Max Lee for putting this stuff up on the web and maintaining it !!!

  22. Mel says:

  24. tj says:

    Thanks you so much comments helped much I had the Sprint LG g3. With the factory rest 2 screen follow the comments it works

  25. Rich says:

    thanks a million for this. This helped me to return my Verizon G3 back to stock.

  26. Chris says:

    Ok. I’ve gotten to the part where Flash Tool says READY then I unplug the micro USB like in the video and when I plug it back in it does absolutely nothing. What am I doing wrong?

    • Quique says:

      Go to device manager and change the port again from port 41 to any other port. Windows will tell you that the port is in use by another application. Just proceed and the program will continue normally. This is a Windows issue that will present itself after several attempts.

  36. vaz says:

    I recently messed up trying to root lg g3 d850 , I accodentlynused d855 lollipop instructions and after boot it kept saying. 780 fastboot mode started

    Also in couldn’t follow the above method since during last step it thought my model was d850.

    This is how I got out.

    1. Hard reset and get into recovery mode , this will work even if you copied wrong ROM.

    2. Then follow above steps line by line. Don’t miss any and use the right model. In my case it was d850.
    Use originallg cable only and also make sure you put the battery in or else you will never get firmware update mode. I struggled here since I only connected USB cable without battery.

    3 . once recovered , follow steps again and root the device and install twrp recovery listed in this website.

    4. This time use the right model and ROM the device.
    I got lollipop rom and gapps ROM installed and its really cool with no boaltware.

    Hope u find this helpful 🙂

  58. Joe says:

    Yet another tutorial from here that doesn’t offer anything other than failure. Tried to root the G3, and that tutorial killed it. Tried this one to revive it with no love. I wouldn’t trust this guy at all.

  59. SigKill -9 says:

    For those who are having a problem, Read this and see if it helps.

    I too was having an issue reverting back to KitKat from Lollipop on my Verizon LG G3. First, I couldnt set the COM port to 41 because the LG COM port never appeared in my device manager… Every time I would get to the part where you start up the flash tool program it would never recognize my device and wouldnt begin the flashing process. This was most likely due to the COM port not showing up in the device manager.

    Here’s what I did to get it to work:
    Do this FIRST before you do anything else listed in this tutorial.
    1) Power on the phone and let it boot to the home screen.
    2) Plug it in to your PC using the cord that came with the phone.
    2) Install the USB drivers.

    What I was doing wrong was installing the USB drivers while the phone was in the Firmware Update mode. This prevented the drivers from installing correctly. This tutorial worked only after I booted my phone to the home screen and then installed the USB drivers. Once I did that, the COM port appeared in the device manager and I set it to 41. Then I booted the phone to the Firmware Update screen and everything went smooth as silk after that.

    Hope this helps!

  65. Damion Miller says:

    I returned my LG G3 back to stock to return it for warranty. After flashing it to stock factory, I took the OTA updates and updated it to Lollipop. it’s completely stock OTA unrooted but the phone still shows “modified” on the software status. Any idea why? Thanks for all your work with Android devices Max!!

  66. Fiaz says:

    First i try to unbrick my phone and it gives error at the end by typing on the screen as “Data reset 2”. after that i had restarted it again and again. Doing hard reset but all in vain.

    Please help me, i am very much sad

Tried again with some of the tweaks from the comments, it worked again, yet still it continues to boot loop. It’s the D851 model and I used the right .tot and .dll files. Any ideas or am I stuck with a very expensive paperweight thanks to an OTA update?

    Please someone help me!
    Yesterday morning I started downloading an update (via cable) through LG PC Suite. During the process something went wrong, the program stopped and now my LG G3 is stucked on the firmware update screen.
    I tried removing the battery and restart, but the firmware screen come again.
    I tried hard reset, I confirmed yes, the lg logo came but then firmware screen again 🙁
    I tried following a LG Flash Tool online with a .kdz file, the process starts but always interrumpt when the phone screen shows a red “arrest”.
    Then I found this guide, I followed all the steps except the port one, because I can change it because the firmware-screened-phone isn’t recognized 🙁 the program works fine until it says “ready”. I unplug the phone, wait for 3 seconds and plug in again. Waited for almost half an hour but nothing happened!

    Please, please someone help me! Any advise please? What can I do?

  82. Tosin says:

    My Lg g3 turn off itself and failed to boot to home screen whenever I try to turn it on back. I clean the cache through the factory recovery mode but yet it not loading and now the screen is just blank when I on it or when I try to get it to download mode or factory recovery mode. Please I need your assistance

  89. Dan says:

    Hey, so im currently having the same problem, and noticed a ton of people saying to switch usb. this brings me to a problem i also had while installing windows 7 on my pc, if your having this issue with installing lg g3 stock rom, try using a usb 2.0. alot of hardware / software is not ment to read 3.0 without the driver installed on the device, so this can be what is causing it to not read properly.

  90. mario says:

    HI, just wanted to share my experience.

    It worked, but not straight away. Initially I got number 2 at the end. Then I played with another USB port, but that still didn’t work. Eventually I went back to the original port to try one more time before trying it on another system. To my surprise I saw “Passed” and number 3 on the screen.

    This was done on Windows 8.1 using USB 3 port (blue one) and by following the guide above.

    Thanks very much, You saved me couple hundred pounds.

  91. Rich says:

    Can you upgrade to 5.0 after doing this?

    Also, how can I easely go back to lolippop?
    Thanks guy’s

    • Jay says:

      Were you able to get your phone working back on Koodo and to Lolippop? I also have not had any luck with finding the Koodo stock firmware.

      Hey man, i have koodo as well. how did this go for you? Really having concerns as i cant find a specific stock ROM for koodo or telus.

  98. Waqar says:

    Hello I have an AT&T LG G3 D850 and for some reason when I attempt to go this I get stuck at 6% and it will get stuck at “LAP Bin_User_Mode” and finally would say “Erase Command Failed”. To my knowledge the partition on the phone has been wiped from TWRP making the phone at this point absolute useless. The only mode I can access is Dowload Mode and TWRP Recovery but even in recovery I cant do anything because the partition has been wiped. What can I do at this point? Thanks

  99. Tommy says:

    For those of you still getting stuck, this is after 20hrs of debugging.
    I was using a win8.1, and getting no head way even when I switched it to run as admin on win7 compatability. Run the program on a Win7 computer, with a usb2.0 plug, don’t run it on a 3.0 plug. It should take a total of 30min including all the downloads. I used a oem HTC cable, so don’t worry about having to use an LG cable. If you have any questions, please let me know.

    A tip from my experience –
    Don’t use USB 3.0 as you’ll get a “download failed” error.

    Made my day.
    Thought my phone was bricked forever when I got the “Factory Reset Status 2”.
    Only thing that I did differently than the instructions above – in the LG Flash tool, after I specified the dll and s/w fields, I changed the action mode to Board DL as opposed to Upgrade DL.

    The method worked perfectly fine for me, thank you very much for the tutorial!

    help

  124. Nayuta says:

    Okay, after about 5-6 attempts and many hours of frustration and anxiety, I was able to unbrick my phone and get it back to stock ROM much thanks to the XDA dev and these tutorials. Thank you so much.

    I figured out how to solve my problem and successfully flash the stock ROM on my LG G3 LS990. I am using Windows 10. You must download the correct LG drivers for it to detect the phone and for you to be able to change the COM port to 41. If you don’t install the correct version of LG drivers, it will not show the ports in device manager. There are several versions floating around so try and see which one works for your phone. It took me awhile to figure this out. Once I installed the correct drivers from this blog, it detected my phone and showed the ports in device manager and I was able to change the COM port to 41.

    I had to use the generic dll instead of the sprint specific dll when flashing. I tried using the sprint specific dll several times and got “download failed” at about 47%. You can find the generic dll (LGUP_8974.dll) from this guide: “How To Restore The Sprint LG G3 (LS990) To Stock w/ LG Flash Tool” on XDA website.

    I missed a crucial step and it caused me to get stuck at the “Factory reset status 2.” REMEMBER to change the action mode to Board DL. This is CRUCIAL!

    I was unable to get into the download mode several times and got stuck in the Firmware update screen but if you just plug the phone in and follow the same instructions from beginning to end, it will still work. Don’t worry if you don’t get back into the download mode. The flash tool will recognize and still flash the device if you have the correct drivers and COM port number.

    I was finally able to flash and get to the ATT screen and followed the instructions from here:
    When the device restarts and boots into the ATT screen it will give you this: “do not touch this screen” and an option to “CLICK OK”. You click ok and then you want to HOLD the POWER BOTTOM and click on NORMAL BOOT at the SAME TIME. Your phone will reboot to the new/restored phone menu. I unplugged the phone from the computer even though it was only at 89% complete on the LG Flash tool. Got my phone back up and working. Yeah!!!!

    Thanks everyone for saving my phone.

  125. Nayuta says:

    You can contact me if you have any questions or need help. I will try my best to help you based on my experience.

    • Anthony says:

      Would the generic work with a rogers phone as well? im at the point of pulling my dreads out one by one, and already ove 6 hours of screwing with this and still getting the “cannot change to download mode” while stuck on the firmware upgrade screen (the black one not the blue #2) . i had already gotten through the flashing and got stuck on the red2 screen but some how managed to get stuck back on the firmware upgrade screen and now the furthest i can get is to cannot change to download mode or it will go for 200+seconds and then give me the error “we cannot communicate with the phone.

  131. Alex says:

    Guide helped a lot thanks!!

  132. Emma says:

    there is a quicker way to do it. Turn off your phone, then hold power button and volume down together in the same time, when will the LG icon come then unhold and press the same buttons in one time again then will show up the message if you want to do factory reset.

  133. Max says:

    i tried this method many times and failed many times and thanks god in the end i made it to restore my soft-bricked G3 (i accidently deleted the system partition during flashing custom ROM)! this is what i did:

    1. i simply followed each and every steps in this guide. initially i worked as expected but somehow i got the error message stated that “cannot find/connect the phone” afterwards, stuck around 6%.

    2. i tried using different USB ports on my PC but the same error came out. no progress i thought.

    3. i changed the option from LG FlashTool from UPGRADE to BOARD and redid the process. this time it worked better but still got the same error at 65% (much better huh?).

    4. i unplugged my G3 (without exiting the flashtool, left it just like that), pulled out the battery and reentered the download mode (in the firmware update screen). the process somehow continued a little bit before the same error came out.

    5. i closed the flashtool, unplugged my G3 and REDO ALL THE PROCESS FROM THE BEGINNING (and chose the BOARD option). finally that way i managed to successfully completed the process but on my G3 blue screen was not no.3, it was no.0 (even though the flashtool stated “pass”)! i’m just simply unplugged and pulled out the battery (exactly like the steps mentioned) as if it was no.3 on my screen and followed the instructions and ultimately revived my G3!

    the moral of the story: don’t give up on your phone and DON’T EVER DELETE THE SYSTEM PARTITION DURING FLASHING CUSTOM ROM(S)!
