LG Mobile Support Tool checks for new versions and updates the firmware of all LG devices that are connected to the computer. Being aware of any possibility to increase the phone’s performance is critical. Updating the version of the firmware is part of this process. So, in order to use this application, you need a fast internet connection, the USB cable, and proper USB divers for the LG device. The last one though can be done by the program itself.
As complicated as it sounds, updating a firmware version is actually easier than imagined with this tool. It reduces everything to a small number of clicks.
