This process of modifying your phone can be extremely risky and we do not recommend doing so unless you're an experienced android user or into app development.
In other words, rooting, the act of unlocking your phones to their potential although illegal but permitted by most manufacturers, is to utilize everything that your smartphone offers.
While this article only gives an insight of the process, no responsibility will be accepted if in case your phone will be bricked (partially dead), malfunction or anything else that's a con of the process. We'd like to request you to adhere to the same.
Android 7.0 is out to everyone finally and there's Cyanogenmod, a custom ROM developer who works hard to bring their features to most of the smartphone models out there. With the official build of Cyanogenmod 14 for Xiaomi Redmi 1s, people can finally test it out on their devices while most of the process remains the same.
It's now evident that you can install the custom ROM on your phone. Before doing so, it's mandatory to back up all your phone data and save it to a location that you can easily access on your PC so that you can put it back to where it was post-installation.
TWRP (teamwin recovery project) is usually made use of for purposes like these. You'll be required to download the appropriate version of the same so that it works as developed. It's also mandatory that you charge your smartphone so that you'll have plenty of battery capacity enough for the process.
A detailed information about installing the same can be found here. As a pre-requisite you'll need to have CM14 files downloaded along with Google Apps. While Cyanogenmod is a fun experience to explore everything that is provided by the developer, it's undoubtedly one of the best ROMs out there with tons of people switching to it as the days follow.
However, if you are one of the stock lovers like us (but we use Nexus phones) most of us won't really switch to one, due to profound love for the stock OS from Google.
If you are an experienced user and wants to try out some new features that are generally not available directly on the stock rom then this is the best time to get your phone to Cynogenmod since the following build is found to be stable.
