Get Lollipop on LG G3 and Root It – Starting from Scratch

42

Lollipop is making its way to several devices other than the Nexus or Moto series smartphones. Certain variants of the LG G3 have already received the updated officially. But what if you’re already rooted or running a custom ROM, you can’t or I would say, you won’t get into the hassle of reverting back to stock completely and doing it all over again. So now is where we get in, we will guide you to Install Lollipop on LG G3 running a rooted or custom ROM and root it again on the Lollipop.

The G3 was launched during May 2014 and came with Android 4.4.2 KitKat out-of-the-box. It runs on a powerful 2.5 GHz Quad-core Krait 400 processing unit with a Qualcomm Snapdragon 801 chipset, supports an Adreno 330 GPU for excellent gaming experience, and a 13 MP high-res camera with dual-LED for vibrant photographs. G3 also presents some unique features like Dual Window, Guest Mode, and Smart Code etc.

Having such an outstanding device in your hand and running Lollipop on it, isn’t enough, you need it to be rooted to play with the inside. The first thing to be done is to have bumped TWRP installed on your G3, then flash the stock Lollipop ROM provided by sooti at XDA-Developers forums and eventually root it with SuperSU. We shall guide you through the complete process, so let us have it started.

Warning!

This guide involves installing Lollipop on LG G3 D855 unofficially and rooting it, which is a revertible yet risky process if done incorrectly. Be sure of what you’re doing and proceed only then. DroidViews or any of its community members shall not be held liable for any damage that occurs to your G3 before, during or after this process.
