These modified versions are known as Custom ROMs , Cooked ROMs or we just say they are custom Android versions .

Now yes, we go on to reel the most powerful, popular and successful custom ROMs that populate the rich Android ecosystem.


My first choice is definitely CyanogenMod. It is not the first custom ROM that I have tried but yes the one that has served me best during all these years . Currently the Cyanogen project is closed, with Lineage OS being its direct successor as of 2017. Millions of customization options, fast and like itself and a stable system like few others, probably the most widespread and popular cooked ROM for Android of the end times.

It allows you to create different notifications by vibration or anchor apps to the lock screen, to give a small example of its possibilities.

Along with CyanogenMod Paranoid Android is one of those customs ROMs that has always been at the top of this type of top list. In addition to having a lot of customization options, it has interesting details such as the hybrid mode , which allows us to display the apps on the mobile as if we were on a tablet. Or the floating mode, that lets us open a miniaturized version of an app while we continue full screen in the current application.

The official ROM is only available for Nexus, Oppo and OnePlus devices, but we can find many more compatible models in places like the XDA Developers forum.


But wasn't MIUI the Xiaomi terminal system? Yes, but it is also an open ROM that can be installed on devices from other brands. The operating system is very reminiscent of Apple's iOS , and has several functions that we will not see in other Android systems: the Child Mode , Showtime , pop-up view, blacklists, data statistics, the MiCloud, personalization themes and more.

Carbon ROM

One of the lightest ROMs we can find , based on AOSP (Android Open Source Project). It also has a lot of options and settings but it doesn't have as many apps as the rest of the custom ROMs: Widgets, clock Chronus and lock screen customization. In any case, a ROM worth trying.


The PAC-MAN ROM. An all-in-one that takes the best of other hit ROMs like ParanoidAndroid, AOKP and CyanogenMod . If you like any of these 3 you should definitely give PAC ROM a try. In addition, its ROM is stable and it has a great interface.

BlissPop may not be the most popular ROM out there, but it has several features that set it apart from the rest. Total customization to change fonts, colors, texts and its "Bliss" interface. As a curiosity, has a specially designed left-handed configuration .

crDROID supports a large number of devices. It is based on CyanogenMod and AOSP, and takes a lot of ideas from other ROMs like OmniROM or SlimROMs. It has a manager to change skins in a very agile way and supports a large number of devices.

Cataclysm ROM

A light ROM and very similar to the Android base image. Even so, it has several customization options for the lock screen, notifications, and status bar. People like it because it has few bugs and hardly lets you down . The official version of Cataclysm is only for Nexus devices, but on forums like XDA Developers there are a few additional smartphones available. The project was closed in early 2016 after a message posted on Reddit by its developer β€œ I have been working on Cataclysm for 4 years ... this has stopped having fun for a long time and I think that from now on I will dedicate my time to other projects ”. A shame

Vanilla Rootbox

It is not a very widespread ROM to say, but it does have some pretty interesting visual details. It is a good mix between CyanogenMod and AOKP, and although we have not seen continuity of the project since 2014, it is a ROM based on Android 4.2.2 quite light and that makes very good use of the battery of the terminal.
