One M7 users are the really disappointed with HTC as they are still pending to receive the highly anticipated Android 5.0 Lollipop update. If you are among them, then you should start forgetting about HTC and obtain the update from somewhere else.
We are referring to the Liquid Smooth ROM that was recently launched by a senior developer on XDA. Better known as the LS ROM, it contains the newer Android 5.0.2 Lollipop OS and it is made specifically for the HTC One M7.
The thing is that the LS ROM is free of any major issues and this is why you are highly encouraged to apply it on your device. The only pain with the LS ROM is its installation that can only be done manually.
The process might be tedious in every way but it is well worth the effort. So if you are open to applying the LS ROM on your One M7, you can head over to XDA to download the firmware update. There, you will also find a simple guide that is very easy to follow.
