How to Erase Android Operating System: Guide for Complete Reset and Installation of New OS

Erasing the Android operating system is a process that can be straightforward for basic device resets or more involved when preparing to install a different operating system. This guide outlines the methods to effectively reset or completely remove the Android OS, ensuring you are well-informed and prepared for both tasks.

Erasing Android via Factory Reset

The most common method to erase the Android operating system is through a factory reset. This process will remove all user data and apps, bringing the device back to its original state. Follow the steps below for a clean reset:

Backup Your Data

Before proceeding, make sure to back up any important data. The factory reset will delete everything on the device.

Access Settings

Open the Settings app on your device. Navigate to the System or General management section. Tap on Reset or Reset options. Select Factory data reset. Review the information and tap Reset phone. If prompted, enter your PIN or password. Confirm by tapping Erase everything.

Restart

The device will restart and be restored to its original factory settings.

Erasing Android for Advanced OS Installation

If you wish to completely remove Android and install a different operating system, such as a custom ROM or a different OS, the process is more complex. Follow the advanced steps outlined below:

Unlock Bootloader

This initial step varies by device. Ensure you enable Developer options and then enable OEM unlocking. Use fastboot commands to unlock the bootloader.

Download Required Tools

Install ADB and Fastboot on your computer. Download the new operating system or custom recovery, such as TWRP.

Boot into Fastboot Mode

Turn off your device. Boot into fastboot mode, usually by holding the Volume Down and Power buttons.

Flash New OS

Connect your device to the computer via USB. Use the command line to flash the new operating system. For example:

fastboot flash recovery recovery_fastboot boot recovery_

Wipe Existing Data

Once in the custom recovery, use the options to wipe data and cache.

Install New Operating System

Follow the specific instructions to install the new operating system.

Important Considerations

Warranty: Unlocking the bootloader and flashing new software may void your warranty. Bricking: There is a risk of damaging the device. Ensure you follow all instructions carefully. Data Loss: All data will be lost during this process. Ensure backups are made beforehand.
