The Samsung Galaxy Note 2 has only slimmest of chances, if any, of receiving official Android 5.1 update from Samsung via OTA or Kies firmware package. The device is more than 2 years old and manufacturers more often than not tend to completely forget about such devices. But the developer community doesn't, thankfully, and with no surprise, the CM12.1 lands on the Galaxy Note 2, bringing the Android 5.1 update along too.
You’ll get rid of Samsung’s custom skin, TouchWiz, for good, while getting the ever-pleasant stock UI of Lollipop, that’s won hearts of many people and is arguably the best UI mobile screens have seen. We've been huge fan of stock UI since the days of Holo UI from Android 4.0 Ice Cream Sandwich, and with Lollipop, that love has only grown exponentially — as also the feeling that there is literally no place on earth for a UI like Samsung’s TouchWiz.
So, it’s a welcome download. The unofficial Android 5.1 update for Galaxy Note 2 gets you the latest OS, latest features and also cool customization options from the CM12.1. What else could you ask for?
Sure, the ROM is currently under heavy development, and only alpha builds are available, but that’s good enough if you are keen on testing out the new features in 5.1.
And in any case, if you want to go back to official Samsung firmware for your Galaxy Note 2, you can do so pretty easily — a simple firmware flash using Odin software is all it takes to remove custom ROM, custom recovery and root, all in one shot, and restoring the phone back to stock, Samsung firmware. Follow through to the next page for instructions.
Note: As you already know, it’s not an official Samsung Android 5.1 update for Galaxy Note 2, so expect few kinks at some corners of the ROM that are yet to be fixed by the team. Any major bugs will be reported below.
