LG G3 Vigor was released in the US in September last year, the smartphone already offered with different model, it’s branded as LG G3 beat and G3 S before Sprint and AT&T rebranded it as G3 Vigor with LS885 and D725 model number. However, since this phone released, no one confirmed that superuser access gained successfully. Most likely as it is not a flagship smartphone and it’s less popular, so it does not attract developers to build root utility for this device.
But everything has changed since the new LG root toolkit discovered, we are now able to get root on Sprint LG LG G3 Vigor and some other devices, including the new released LG G Flex 2. The toolkit was originally created specifically for the LG G2 running Android 5.0 Lollipop update, but it also works on the previous version of Android (Kitkat).
With root access we can run any application that requires superuser privileges such as full backup app, Wi-Fi tethering or even enhancing Android UI and functionality with Xposed Framework and its modules. For example, you can utilize Flat Style status and navigation bar module, which can make your phone become more Lollipop by automatically change navigation and status bar color to match with the app color, it could also change the navigation icons to the new Android 5.0 icons.
The new toolkit has been confirmed to work with the Sprint LG G3 Vigor (LS885), but no one has confirmed it to work with AT&T variants (D725), but it does not mean it can not work but maybe no one has tried it yet. If the AT&T software isn’t too different with other variants or there’s no additional security patches, then the toolkit should work great to root the AT&T LG G3 Vigor without any difficulties.
