What Will Happen to a Flash-Rommed Phone When I Update the Software?

When it comes to updating the software on a flash-rommed phone, which is a device that has had its firmware replaced or modified, several outcomes are possible depending on various factors. This article explores the potential results, risks, and best practices to consider before initiating an update.

Loss of Customization

If you update the software on a flash-rommed phone, you might lose any custom modifications or custom ROMs you had previously applied. The phone may revert to its stock firmware upon a successful installation of the official update. This can be a significant setback for users who heavily rely on custom settings and features.

Bricking Risk and Data Loss

The risk of bricking the device is another concern. Bricking renders the device unusable, particularly if the update is not compatible with the flashed firmware. This risk is heightened if the update process is interrupted or if the firmware is not specifically designed for the device model. Additionally, updating the software may result in data loss, especially if the update process requires a factory reset or fails during installation.

Security Improvements and Positive Changes

On the positive side, a successful update can bring important security patches, bug fixes, and new features that enhance performance and stability. However, these improvements come with the aforementioned risks and downsides to consider.

Compatibility Issues

After updating, some apps or features that worked with the previous custom firmware may no longer function as expected, leading to compatibility issues. This can affect user experience and potentially limit the functionality of the device.

Best Practices to Minimize Risks

To minimize the aforementioned risks, it is highly recommended to back up your data and carefully read any instructions related to the update process. If you are using a custom ROM, it is especially important to follow detailed instructions and verify the build compatibility before proceeding.

Method of Rooting

It's also important to consider if you mean "flashed" to be "rooted." Rooting ensures that you have administrative access to the device and allows you to install custom ROMs and modify system settings. If by "flashed" you mean rooted, the process of updating the software on a rooted device is slightly different. Since rooted devices do not receive over-the-air (OTA) updates, you must update the software manually. If done correctly, there should be no issues. However, if you flash the wrong build, you could wind up with a device that is no longer functional.

Before proceeding with any update, it is crucial to identify the software build you currently have by opening the "About Phone" tab in your settings menu. This will provide you with necessary information to ensure that you are installing a compatible update.

Conclusion

Updating the software on a flash-rommed or rooted phone comes with both opportunities and risks. While it can bring security enhancements and new features, it also poses a risk to your customization, the potential for bricking, and data loss. To protect your investment, always prepare thoroughly and follow the instructions carefully. Regular backups and a detailed understanding of your device's compatibility can significantly mitigate these risks.

By following these best practices, you can make informed decisions and enjoy the benefits of a well-updated device without facing major setbacks.
