Another great news is, the new method has been compatible with the new official update from LG – LS991ZV5, which means that we can still get root on Sprint LG G4 running ZV5 software version.
Sprint just mentions that the ZV5 update only brings minor update as it still running Android 5.1 Lollipop. Although it is associated with Reactivation Lock, but a lot of people got numerous benefit from it. Some users at xda reported that they now have better performance and much longer battery life, the touchscreen now became more responsive. It’s a must-have update for LS991 users, you won’t regret installing it, let alone you still have an opportunity to root it.
