Does Factory Reset Remove Custom ROM? A Comprehensive Guide

Have you ever found yourself trapped in a software glitch, plagued by performance issues, or simply yearning for a fresh start with your Android device? A factory reset might seem like the ultimate solution, but what about the custom ROM you’ve meticulously installed? Will it be wiped clean along with everything else? This article will delve into the intricate relationship between factory resets and custom ROMs, providing a comprehensive guide to help you navigate this critical decision.

Understanding Factory Resets and Custom ROMs

Before we dive into the specifics, let’s first clarify what we’re dealing with:

Factory Reset: Essentially a software “clean slate” for your device. It reverts your phone to its original state as it was when you first unboxed it. This means deleting all your personal data, including apps, photos, videos, contacts, and settings.

Custom ROM: A modified version of Android’s operating system designed to enhance functionality, improve performance, or introduce new features. Unlike the stock ROM provided by your device’s manufacturer, custom ROMs are developed and maintained by independent developers.

The Impact of a Factory Reset on Custom ROMs

The truth is, a factory reset will completely remove your custom ROM, returning your device to its original stock ROM. Here’s a breakdown of why this happens:

1. Overwriting the System Partition: During a factory reset, your device’s system partition (where the operating system resides) is essentially overwritten with the original software image. This includes wiping away any modifications or replacements made by your custom ROM.

2. Reinstalling Stock Recovery: The recovery partition (which facilitates system updates and factory resets) is also restored to its default state. This means the custom recovery image, often installed alongside your custom ROM, will be replaced by the stock recovery provided by the manufacturer.

3. No Data Persistence: Since a factory reset wipes all user data, this naturally includes any custom ROM files, configuration settings, and associated data.

Scenarios Where You Might Consider a Factory Reset

While it’s crucial to understand the implications of a factory reset, there are scenarios where it might be a necessary step:

  • Troubleshooting Software Issues: If you’re experiencing persistent bugs, crashes, or performance issues, a factory reset can often resolve them by starting fresh.
  • Preparing for Sale or Donation: Before giving away or selling your device, a factory reset ensures all your personal information and data are erased, offering peace of mind.
  • Switching from a Custom ROM Back to Stock: If you’re unhappy with your custom ROM and want to revert to the manufacturer’s original software, a factory reset is required.

Strategies for Reinstalling Your Custom ROM

If you decide to perform a factory reset and subsequently want to restore your custom ROM, here’s what you need to do:

1. Unlock Your Bootloader: This step is often required to install a custom ROM. It enables you to access and modify the system partition, allowing for the installation of custom software.

2. Download the Necessary Files: Obtain the latest version of your custom ROM and the corresponding GApps (Google Apps) package. You’ll also need the appropriate custom recovery image for your device.

3. Flash the Custom Recovery: This involves using a tool like fastboot to replace your stock recovery with the custom recovery you downloaded.

4. Flash the Custom ROM: Boot into the custom recovery mode, select “install,” and navigate to the custom ROM file you downloaded. Flash the ROM and follow the on-screen instructions.

5. Install GApps: After flashing the custom ROM, install the GApps package using the custom recovery. This step will provide essential Google apps like Gmail, Play Store, and Google Maps.

6. Reboot: After flashing both the custom ROM and GApps, reboot your device and enjoy your newly restored custom experience!


A factory reset is a powerful tool for resetting your Android device to its original state, but it comes with the consequence of erasing your custom ROM. While it might seem daunting, reinstalling a custom ROM after a factory reset is achievable with a bit of technical knowledge and preparation. By understanding the intricacies of custom ROMs and factory resets, you can make informed decisions about your device’s software experience and confidently navigate the process of restoring your customized Android environment.


1. What is a Factory Reset?

A factory reset is a process that restores your device to its original state, like when you first bought it. This means removing all your data, apps, and settings, including any custom modifications you’ve made. Essentially, it returns your phone to its factory defaults.

The factory reset process varies depending on the device and operating system, but generally involves navigating to the settings menu and selecting the “Reset” option. It’s important to note that a factory reset cannot undo any damage done to your phone’s hardware.

2. Does a Factory Reset Remove a Custom ROM?

Yes, a factory reset will remove a custom ROM from your device. This is because a factory reset essentially reverts your device back to its original state, erasing all user data and customizations, including any custom ROMs you may have installed. Think of it as a clean slate, returning your phone to its original state as intended by the manufacturer.

After a factory reset, your device will boot up with the stock ROM that came pre-installed on the device. This means you’ll need to reinstall your custom ROM if you want to use it again.

3. What Happens to my Data During a Factory Reset?

A factory reset completely wipes your device’s internal storage, deleting all your data, apps, settings, and customizations. This includes your contacts, messages, photos, videos, music, and any other files you have stored on your device.

Therefore, it’s crucial to back up your data before performing a factory reset. You can use cloud services like Google Drive or Dropbox or connect your device to your computer to save your files.

4. How Do I Back Up My Data Before a Factory Reset?

There are several ways to back up your data before a factory reset. You can use cloud services like Google Drive or Dropbox to automatically sync your data to the cloud, or you can manually copy your files to your computer.

Alternatively, you can use your device’s built-in backup tools to create a backup of your settings and data. However, it’s always a good practice to have a backup of your important data on multiple devices or storage locations for safety.

5. Can I Recover my Data After a Factory Reset?

Unfortunately, once you perform a factory reset, your data is permanently deleted from your device. There is no way to recover it directly from your phone’s storage. However, if you backed up your data before the reset, you can restore it from your backup.

Cloud services like Google Drive and Dropbox allow you to restore your data from your backups, while a local backup on your computer can be used to restore your files manually.

6. What Happens to My Custom ROM After a Factory Reset?

A factory reset will completely remove your custom ROM from your device. After the reset, your phone will boot up with the original stock ROM that came with the device.

To use your custom ROM again, you will need to reinstall it. This involves flashing the custom ROM files onto your device using a tool like TWRP recovery. Refer to the instructions provided by the custom ROM developer for specific flashing procedures.

7. Is There a Way to Save my Custom ROM Before Resetting?

There isn’t a direct way to save your custom ROM before resetting your device. You can’t simply back up the ROM and restore it later. However, you can save the custom ROM files (including the ZIP file, kernel, and other related files) to your computer.

You can then reinstall the custom ROM after the factory reset by following the flashing instructions provided by the ROM developer. This will allow you to revert back to your custom ROM after the reset.
