What is Custom Rom ? A brief Introduction

A custom ROM (aka aftermarket firmware) is a modified version of an existing Android operating system. Some custom ROMs are based on existing mobile OSes, like Android, and some are based on desktop or laptop operating systems, such as Windows or Ubuntu. They’re different from devices that use stock firmware in that they can offer features and enhancements not found in stock versions of Android, but they’re also different from forked projects like CyanogenMod in that every piece of code was written specifically for that device. What does a custom ROM do for you? Let’s start with what it doesn’t do.

Why Use Custom ROM?

Android has plenty of great features and options already built in, but it also allows you to load custom ROMs onto your device. By doing so, you can customize your phone to work exactly how you want it to. Plus, there are a ton of cool tweaks that are available with custom ROMs, like themes and enhanced battery saving modes. The ability to swap out Android’s user interface for something totally different is one of its greatest strengths – if you don’t love what Google put on-screen by default then it’s easy to replace with a new interface from third party developers. There are tons of options out there (more than we could ever feature here), and below are just a few examples of some popular custom ROMs for Android devices…

  1. Evolution X
  2. Lineage OS
  3. Pixel Plus UI
  4. Pixel Experience
  5. Havoc OS

Types of Custom ROMs

There are many different types of custom ROMs. The base ROM for Android phones and tablets is called AOSP (Android Open Source Project), and it’s essentially what every single Android phone runs on when you first take it out of its box. There are also proprietary or skinned versions of Android, like HTC Sense, Samsung TouchWiz, MotoBlur, etc. Although these versions have different looks and feels from each other, they all use AOSP as their foundation. However, there are two ways to change AOSP into something different: with an Xposed Module or with a custom ROM.

Popular Android Custom ROMs (And Their Pros & Cons)

As you’re starting to learn more about Android, you may have heard of custom ROMs. But what are they, exactly? In essence, a custom ROM is an alternate version of your device’s official firmware; it gives users complete control over how their devices look and act. Usually these are developed by a third-party entity who takes existing open source code and modifies it. It’s not uncommon for custom ROM developers to bring features from one device to another through these modified versions. Now that we know a little bit about what they are, the most popular Android custom ROMs are Havoc OS, Evolution X, Pixel Experience & Pixel Plus UI.

How to Install a Custom ROM

First of all, you have to unlock bootloader of your Android phone which means gaining root access for best performance. After that, you have to flash CWM or TWRP recovery on your phone so that it can help flash custom ROMs and other applications later. Moreover, since root gives an open access to files on your device, its recommended that users use secure file managers like ES File Explorer after rooting their devices in order to prevent any file corruption or loss.

Why we need to Install Custom Rom

Is Custom Roms Safe ?

It’s a hard question to answer, as it really depends on how you use your phone. If you’re trying to repair an older device and want to give it more life, then getting a custom ROM might be a good idea. But even with newer devices, keep in mind that rooting/flashing can cause problems for people who don’t know what they’re doing.
