Download stock KDZ firmware for T-Mobile LG Leon LTE (H345)

Lots of folks don’t realize that the stock firmware is a must-have things for those who often mods their Android phone’s software. This also applies to LG Leon H345 users, since this device has been successfully rooted, soon after the device was released and till it get an official update to Android 5.1.1 Lollipop. However, rooting procedure sometimes not go smoothly, since you might get a problem which ended in soft-bricked device.


This is where a LG Leon (H345) stock firmware (KDZ) can be very useful for you to get out of this unpleasant condition. All changes or mods you’ve done on your device will be lost, since all system files, kernel, bootloader, recovery will be replaced with the new one from the KDZ file. Sometimes flash a stock firmware can’t fix a bricked device, but at least this is can be an initial attempt before giving it to the LG repair center.

The KDZ file can be flashed into your phone by utilizing several tools, but the most famous and user-friendly is the LG Flash Tool 2014 utility. But sadly, it’s an executable app running on Windows OS (desktop) environment, and there are currently no supports for Mac OS X or Linux computer. Installation is not required, so we just have to run the app by double-clicking on it.

    you are offering a version that is not actually stock. I need the H34510d so why does this seem to claim that the stock is the file being offered when it is H34510e? A good way for someone to cause others to brick their phone just thinking this is the stock file. Well, it’s not
