How to Install a Custom ROM on Your Android Phone for a Fresh New Look

How to install Custom ROM on Android Device - Android Blog

If you’ve ever wanted to change the look and feel of your Android smartphone, installing a custom ROM is the way to go. Custom ROMs allow you to replace the default operating system on your phone with a new one, offering a fresh user interface, additional features, and the ability to customize your device to your liking. In this guide, we’ll walk you through the process of installing a custom Android ROM on your phone.

Why Install a Custom ROM?

Every Android device comes with its own unique user interface (UI) or default ROM. This UI could be stock Android (AOSP-based) or a customized skin created by the manufacturer, such as Samsung’s One UI or Xiaomi’s MIUI. While some users prefer feature-rich UIs with themes and customization options, others prefer a cleaner and simpler experience.

This is where custom ROMs come into play. Installing a custom Android ROM replaces the stock ROM or manufacturer’s skin with a different one. Here are some reasons why you might want to install a custom ROM:

  1. Remove Bloatware and Ads: If your current interface is filled with unwanted apps and advertisements, a custom ROM can help you get rid of them for good.
  2. Get the Latest Android Version: If your device is no longer receiving official updates from the manufacturer, a custom ROM based on a newer Android version can give your phone access to the latest features.
  3. Unlock Hidden Features: Some custom ROMs can unlock hardware features that are not accessible in the stock configuration.

It’s important to note that installing a custom ROM can void your device’s warranty, as it typically involves unlocking the bootloader. Additionally, if not done correctly, it can lead to temporary or permanent damage to your device.

Pre-Requisites for Installing a Custom ROM

Before you start the installation process, there are several things you’ll need:

  1. An Android device: This is obvious, but you’ll need a compatible Android smartphone or tablet.
  2. An unlockable bootloader: Depending on your device, you’ll need to unlock the bootloader. Specific instructions can usually be found on XDA Forums or the manufacturer’s website.
  3. A custom recovery: TWRP (Team Win Recovery Project) is a popular choice, but some ROMs require a specific recovery image.
  4. The custom ROM ZIP file: You’ll need to download the custom ROM you want to install. Check the XDA Forums or other sources for ROMs compatible with your device.
  5. (Optional) GApps (Google Apps): Some custom ROMs don’t come with Google apps pre-installed, so you may need to download a GApps package.
  6. Access to a computer with ADB and Fastboot installed: This is necessary for certain steps in the process.
  7. Patience: Installing a custom ROM can be a time-consuming process, so be prepared for some waiting.

How to Install a Custom ROM

Now that you have everything you need, let’s walk through the installation process step by step:

Step 0: Back up your data Before you start, create a backup of all your data, as the installation process involves a full data wipe. This ensures you can restore your data later.

Step 1: Download the correct ROM Visit the XDA Forums or other sources to find a custom ROM that’s compatible with your device. Download the ROM ZIP file to your computer or phone.

Step 2: Download GApps (if needed) If your chosen custom ROM doesn’t include Google apps, download the appropriate GApps package and transfer it to your device’s internal storage.

Step 3: Boot into TWRP Boot your device into TWRP recovery mode. You can find instructions on how to do this for your specific device on the XDA Forums.

Step 4: Installing the Custom ROM

  • Before proceeding, create a backup of your current system in TWRP.
  • Wipe your phone’s data by going to the “Wipe” menu in TWRP and performing a factory reset.
  • Format the /data partition.
  • Copy the ROM and GApps files to your phone’s internal storage.
  • Install the ROM by selecting the ZIP file in TWRP.
  • Install GApps (if needed) in the same way.
  • Reboot your device.

If everything goes smoothly, your custom ROM should now be installed. Wait for your device to boot into the new ROM, which may take some time during the initial setup.

That’s it! You’ve successfully installed a custom Android ROM on your phone, giving it a fresh new look and additional customization options. If you ever want to switch to a different custom ROM, simply repeat the installation process.

Note: Please be aware that custom ROM installation steps can vary depending on your device and the ROM you choose. Always follow the specific instructions provided for your device to avoid any issues.

Step 5: Setting Up Your Custom ROM

Once your device boots into the new custom ROM, you’ll go through the initial setup process, similar to when you first got your phone. Follow the on-screen instructions to configure your language, Wi-Fi settings, and other preferences.

Here are a few additional tips for setting up your custom ROM:

  • Google Account: If you installed GApps, you can sign in with your Google account during the setup process. This allows you to access the Play Store, Gmail, and other Google services.
  • Customization: One of the key benefits of using a custom ROM is the ability to customize your device extensively. Explore the ROM’s settings to change the look and feel of your device, adjust system animations, and personalize your device to your liking.
  • Backup and Restore: If you created a backup of your data before installing the custom ROM, you can now use it to restore your apps and data. This can help you get back to your previous setup quickly.

Troubleshooting and Tips

Installing a custom ROM can be a smooth process, but occasionally, issues may arise. Here are some troubleshooting tips:

  • Stuck in a Boot Loop: If your device gets stuck in a boot loop (constantly restarting), return to TWRP recovery and restore your previous system backup.
  • No Google Apps: If you forgot to install GApps or chose a ROM without them, you can flash GApps separately from TWRP by selecting the GApps ZIP file and installing it.
  • Compatibility Issues: Ensure that you’ve downloaded a ROM specifically designed for your device model and variant. Installing an incompatible ROM can cause problems.
  • Battery Drain: Some custom ROMs may have different power management settings. If you notice excessive battery drain, explore the ROM’s settings to optimize power usage.
  • Performance Issues: Custom ROMs can vary in terms of performance. If you experience lag or slowdowns, consider trying a different ROM or custom kernel designed for performance improvements.

Remember that custom ROMs are created and maintained by the developer community, so updates and support can vary. Be sure to check for ROM updates regularly or explore other ROM options if you encounter persistent issues.


Installing a custom Android ROM is an exciting way to breathe new life into your smartphone, offering a fresh user interface, added features, and extensive customization options. While the process may seem daunting at first, following the steps carefully and seeking help from the Android community can make it a rewarding experience.

If you ever decide that the custom ROM you’ve installed isn’t to your liking or you want to explore different options, you can always return to this guide and repeat the installation process with a new ROM.
