Instructions

Disclamer: Installing an official firmware through LG flashtool doesn’t void your device’s warranty, but it remains an unofficial process and thus you need to be cautious of it. In any case, you only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.

Backup important files stored on your device before proceeding with the steps below, so that in case something goes wrong you’ll have backup of all your important files. Sometimes, Odin installation may delete everything on your device!

  1. Make sure you have latest LG Drivers installed. It’s required so there is proper communication between phone and PC.
  2. Enable USB debugging on your device. For this:
    • Go to Settings >About phone, and then tap build no. 7 times.
    • Now, go back to Settings > Developer options, and find and use the toggle button to enable ‘USB debugging’.
  3. Download the firmware, Flashtool and Visual runtime file from above.
  4. Install the Visual C++ Runtime Library so that Flashtool works fine.

  6. Put your LG G2 into download mode now. To do this:
    1. Power Off your phone
    2. Now, while pressing both volume buttons, connect your phone to PC using the USB cable. In a moment, G2 will boot into download mode, with Firmware Update written at top. Drivers could start installing on PC, let them. And btw, if this process fails in your first attempt, try again.
  7. Now transfer the firmware file .kdz format to the LG Flashtool 2014 folder. We need it in the same folder we have the LGFlashtool2014.exe, that’s why.
  8. Double click on LGFlashtool2014.exe file to run the flashtool.
  9. On flashtool, make sure that option selected under ‘Select Type’ dropdown is CDMA. And that PhoneMode is DIAG.
  10. Now, click the icon to the right most part of ‘Select KDZ file’ and the select the firmware file: LG G2 D80230b_00.kdz
  11. Make an important selection now, between what kind of installation you are looking for, Normal Flash or CSE Flash. CSE Flash deletes everything, like apps and games, their data and even the internal storage, thus preferred when you have custom ROM installed currently, while Normal flash keeps your data but is recommended only if you are already on LG firmware and have not modified it. Choose CSE Flash for proper installation, but if you are not on custom ROM, you can safely choose normal flash.

  14. The installation will begin. If in case an error occurs, retry from the beginning and make sure everything is OK. Once successful, click exit. Now that you have successfully flashed the firmware, reboot your phone if it doesn’t automatically. The first restart will take more time than usual, so have patience.
