What is Havoc OS?

Havoc OS is an Android Open Source Project (AOSP) based custom ROM. It is one of the highly customizable custom ROM available for android phones.

This ROM is jam-packed with features that you probably will never find in any other ROM.

Apart from the wide range of customizations, you’ll also get frequent updates with the latest security patches and stable performance without compromising battery life.

Havoc OS team also states that this ROM is “All you can dream of and all you’ll ever need”.

Pre-Requisites to Install Havoc OS

You’ll need a custom recovery to install a custom ROM. If you don’t have one installed already then check the below link:

  • NANDroid Backup of device, in case something goes wrong.

A Complete NANDroid backup is recommended as you have to wipe the old system to install the new one. If there is trouble during installation, you may have to revert to your old ROM.

Learn more about NANDroid backup from the following link:

How to Create and Restore NANDroid Backup?

Note: NANDroid backup doesn’t backup internal storage files like Pictures or downloads, make sure to back up all those files manually.

  • Havoc OS ROM for your device.

Head over to the Havoc OS ROM site and download the ROM file compatible with your phone.

  • GAPPS compatible with your device. (Optional)

To gain play store functionality and other google apps, you’ll need to download and flash Gapps.

Head over to OpenGapps, and download the version compatible with your device.

If you don’t find the Android 11 version, then download NikGapps (a custom Google Apps package).

If you want to root your device, then you’ll need to flash the Magisk.

Download Magisk App from its official Github repository.

  • Device charged up to 70%

Charge your device at least 70%. The last thing you want is to run out of juice while installing or troubleshooting custom ROM.
