Samsung Galaxy Tab Pro 12.2 (SM-T900) released with Android 4.4.2 KitKat and Samsung didn’t update the firmware yet to a newer Android version. You need root and custom recovery to flash any custom ROM. In this post I’m going to explain easy step to flash an unofficial CM 12.0 ROM on your Tab Pro 12.2 through custom recovery. I’m using this about a month and happy with it. It is fast and stable while giving you better battery performance and using less system storage.
Android 5.1.1 is the latest version of Android OS. Recently, Google released this version for Nexus Player, the first device to run the latest Android 5.1.1 (LMY47V). They released Android Lollipop not long ago. The first version Android 5.0 was a kind of developer preview version. Material design introduced on the platform for the first time. Then Android 5.0.1 and 5.0.2 released. Another update brought it up to Android 5.1. Now, this is the final version as of writing.
