cara install custom rom dotos di Poco X3 Pro

Hello, welcome to, in this post I will show you how to install a DotOS custom ROM on Poco X3 Pro with the codename vayu/bhima. Before going into the tutorial, I will explain about this ROM.

DroidOnTime (DotOS) is an AOSP-based android custom ROM developed by the DotOS Team. This ROM offers a unique user interface and optimal performance, but still maintains a balance between performance and battery life.

In addition, this Custom ROM also provides an OTA update system with the latest security patches once a month. So, don’t worry about its security and stability.

For the DotOS version that we will install this time is version 5.2.1 which is the final version of the update for Android 11. And then they will focus on developing DotOS version 6.0 based on Android 12.

Installation preparation

  • You have to be willing to lose your phone warranty. If you don’t want to lose the warranty, don’t do this.
  • Back up data. This is mandatory because the installation process will delete all data (such as photos, videos, etc.) on the internal memory.
  • Unlock the Bootloader of your Poco X3 Pro.
  • Flash custom recovery (TWRP) on Poco X3 Pro.
  • Download DotOS 5.2.1 or later. There are two variants, namely Vanilla (without the Google application) and Gapps (already includes the Google application), and in this tutorial we are using the Gapps version.

If everything is ready, it’s time for us to enter the installation steps.
