Before learning how to remove an installed custom ROM, you should first know what a custom ROM is. This refers to aftermarket firmware that many developers create and develop to ensure that you have the latest version of the OS without the bugs to ensure optimal performance of your handset.

However, installing a custom ROM in your handheld device is not easy and you will need a root access for the installation. This does require a tech-savvy person who knows what they are doing. To install the custom ROM, you would have to go through numerous guides to understand the process and then download the correct files for your handheld device. After you install the custom ROM, you may find that the performance of your device significantly improves.

Many people also want to know how to uninstall a custom ROM after installation. Here are the following steps that you should take:

  1. Make sure you root your device before you begin uninstalling the custom ROM. This gives you administrator privileges so that you can access the OS and remove files.
  2. After you root the device, go to Unlock Bootloader.
  3. Install a custom recovery app, such as TWRP.
  4. Download the stock ROM for your device. It may be wise to do this first so that you do not waste time trying to locate the stock ROM.
  5. Using the custom recovery app, select the option Wipe Everything. If that is not available, look for Clean to Install a New ROM. That will enable you to remove the custom ROM and its traces.
  6. Once you remove the custom ROM, install the zip file of your stock ROM.
  7. Through the custom recovery app, select to install the stock ROM. This could take a little long so just be patient.
  8. Once the stock ROM is installed, you have managed to remove the installed custom ROM.

While you are following the above steps, make sure your device is properly charged. You can plug in the charger to your device so that the battery does not die on you while you are uninstalling. This process is power-intensive and your battery will get discharged rather quickly.

Once the stock ROM has been installed, you would need to reboot your device so make sure to switch it off and turn it back on. Check the device to ensure everything is working properly.

Point to Consider

Before you begin the removal process of the installed custom ROM, you may want to backup your data, especially if you want to keep your music and photos. You can backup your data on the cloud. After you finish removing the custom ROM and installing the stock ROM, you can download the backup data from the cloud.

The Bottom Line

Most people will not be able to follow these technical steps. Therefore, it is best to take your handheld device to a professional who knows how to install and uninstall custom and stock ROMs. This will give you peace of mind and ensure that each step is followed correctly and that your device will not have any performance issues.
