Unbrick LG G3 Stuck on Factory Reset 2

Posted on :

This post here is to unbrick LG G3 stuck on factory reset 2 message only. Don’t try this method if your G3 isn’t stuck on factory reset  2 error. I already have a guide to unbrick soft bricked LG G3 which can be used if you want to unroot or return to stock ROM, use that instead. Also, this guide here is for soft bricked LG G3 only, not hard bricked ( what is difference between soft brick and hard brick ?).

We are not responsible for any data loss or other problems that occur by using this tutorial. Flashing ROM deletes internal memory. Use at your own risk.

Requirements:-

  • 1
    LG Flashtool program for flashing ROM on your device
  • 2
    Stock firmware for your model of LG G3
  • 3
    DLL file for you model of LG G3
  • 4
    LG drivers for Windows
  • 5
    PC with Windows on it

All the download links are provided at the end of the post.

How to Unbrick LG G3 Stuck on Factory Reset 2

  • 1
    Download and install LG USB drivers on your PC. If you are using Windows 8/8.1 or higher, please disable the Driver Signature Enforcement from the advanced start up settings. (Google it, if you are unsure)
  • 2
    Download firmware for your model of LG G3 along with the DLL file made specifically for your device version. If you don’t find your model of G3 listed, then mention your model in the comments below, we’ll try to find a firmware for your device.
    Extract the firmware file you just downloaded to a folder. Inside, you will find a file ending with .TOT extension. DON’T FLASH FIRMWARE OF A DIFFERENT MODEL OTHERWISE YOU WILL HAVE A HARD BRICKED DEVICE.

    Download and extract the LG Flash tool program in a folder. Inside the folder, you will find a Setup EXE and MegaLock.dll file. Install the LG Flash tool on your PC but don’t run it. After installing, copy the MegaLock.dll file to C:\LG\LGFlashTool or custom install location, if applicable.

    Insert the USB cable that came with your device to PC but don’t plug it into the device yet. Switch off your LG G3, press and hold Volume Up button and connect the micro USB to your device. You will see that your device’s screen now shows Download Mode message which will change to Firmware Update screen after some time.

    If the device drivers were installed properly then your PC should detect the device. Now open Device Manager -> Ports (COM & LPT), you will find LGE Mobile USB Serial Port along with a COM port assigned by the Windows. If the COM port is other than COM41 then double click on it. A new window will open, click on Port Setting tab and click on the Advance button. Select COM 41 from the COM port number drop down. LG Flashtool software won’t flash ROM onto your device unless it’s connected to port COM41, so make sure that your device is connected to PC via COM41.LGE Mobile USB Serial PortPort Settings - LGE Mobile USB Serial PortSelect COM Port number - LGE Mobile USB Serial Port

IGNORE the message and press OK button on the screen. Now press and hold the power button and tap on the screen where it says Normal & Power button (or something similar).

      Hi, won’t the firmware for your device be “A6WN” (16 GB)? You can find the link for your device’s firmware by going to the xda link I provided on http://wp.me/p4klxZ-dh. If you still can’t find your firmware, comment again :P.
