Here, you can download the older and latest LG Flash Tool for free to install or flash the stock KDZ and TOT firmware on your LG phones.

If you own an Android smartphone, you must be aware of a few things like performing a factory reset, the hardware key combinations to reboot your phone into the bootloader/download and recovery modes, and installing the stock firmware on your device. While the stock firmware can be installed on many Android devices using ADB and fastboot commands, you must use firmware flashing tools like Odin (for Samsung) and LG Flash Tool (for LG) on some OEM-branded devices.

If you own an LG phone or tablet, you can use the LG Flash Tool to install the official firmware with .KDZ or .TOT extension to restore your device to stock. In case you’ve been experiencing some serious issue on your LG phone, or you just want to downgrade or upgrade device firmware, the LG Flash Tool is a must-have utility.

Below, we have provided the direct download links for all available versions of the LG Flash Tool for you. We have collected different versions of the flash tool from different sources. Thanks for autoprime and ieatacid from XDA forums for providing the patched version of the tool to work for users without glitches.

  1. The author even never use the LG FLASH TOOL 2015 OR 2016. This tool need a USB mega lock from LG official, the patched or cracked one does not work at all.

  2. I downloaded both the megalock dll and the ieatacid patched file
    I uninstalled my previous version of LG Flash Tool
    I disconnected from the internet
    I ran the ieatacid setup and it installed successfully
    I ran LG Flash Tool from where it was installed (C:LGLG Flash Tool)
    The Login screen pops up saying ” Login for LGST users”
    I replaced the default megalock dll in C:LGLG Flash Tool with the one provided on this page, but the same screen pops up
    I tried different versions, but I get a screen saying “DLL for megalock is not found”
