After rooting any smartphone or tablet running Android firmware requires a custom recovery installed that helps you install custom ROM. Every Android device comes with a pre-installed stock recovery with limited functionalities that doesn’t allows us to install any Modded apps, sideload features and custom roms. In this post, we will talk about the steps to Install Custom ROM on Any Android.
There are few types of custom ROMs people are using across different devices based on the requirement, it can be either Stock or AOSP. Stock ROMs are basically OEM firmwares, while AOSP are based on Android’s code from public open source directory. Almost all the custom ROMs available over the internet are based on AOSP.
As custom ROMs are based on AOSP, you find any Google Apps installed in it, you have to get GApps Package that needs to flashed after custom ROM in order to get Google Apps.
Moving from Stock ROM to custom may void your device’s warranty. Make sure you are doing or following the steps mentioned below at your own risk. We are not liable if something goes wrong during the process.
Taking a complete backup of the device before proceeding is the best practice to avoid such issues. We commend Nandroid Back Tool to do so.
