I'm making this guide because it took a while for me to find how to update my phone. Go to this website. LG LGMS840 Support: Find Manuals & Warranty Info | LG USA Scroll down and under Manuals & Download click on the Software Update Tab. Download and Install the USB DRIVER and LG MOBILE SUPPORT TOOL. (Your install should go under "LG MOBILE SUPPORT TOOL". If you want to run the updater, run "LG MOBILE SUPPORT TOOL" NOT "LG MOBILE Software Updating Agent Program" ) LG MOBILE SUPPORT TOOL without the phone plugged in: To make sure you have all of the USB DRIVERS installed, click on "Install USB Driver" Select MetroPCS as the Carrier. And DOUBLE CLICK on LGMS840. Once that downloads and installs, plug your phone in. MAKE SURE YOUR PHONE IS IN MASS STORAGE or INTERNET CONNECTION MODE. CHARGE ONLY MODE WILL NOT WORK. (If your phone is in charge only mode, slide the top bar and press USB connected. Then press Internet Connection and Done on the bottom.) When you plug your phone in, the drivers should start installing. You can check on the status by opening the Driver Software Installation in the task bar. It should look like this: The LG MOBILE Support Tool should now look like this: Since my phone is up to date, there is no need for an Update. If your phones needs it though, click on Start Updating. Follow the on screen instructions to complete the update. You need 50%+ battery in order to start the update. If you don't have enough, you'll need to charge your phone. NOTE: Software updates take off ROOT and can reinstall bloatware. Hope this helped!
