fastboot

Fastboot is a command line tool that is used for flashing or installing a custom recovery image or a firmware image on Android devices. It is primarily used for Android devices that have the bootloader unlocked.

Here are some key features of fastboot:

1. Device management: Fastboot allows users to manage various aspects of their Android device, such as flashing firmware, unlocking or locking the bootloader, and rebooting the device.

2. Flashing firmware: With fastboot, users can flash firmware images to their Android devices. This is useful when updating the operating system or recovering from a software-related issue.

3. Flashing custom recovery: Fastboot allows users to install a custom recovery image, like TWRP (Team Win Recovery Project). Custom recoveries provide additional features, such as creating and restoring device backups, installing custom ROMs, or rooting the device.

4. Unlocking bootloader: Fastboot can be used to unlock the bootloader on Android devices. This process allows users to customize their devices by installing custom recoveries, custom ROMs, or even alternative operating systems.

5. Rebooting device: Fastboot provides the ability to reboot an Android device into different boot modes, such as bootloader mode, recovery mode, or normal operating system mode.

It's important to note that using fastboot requires caution and knowledge about your specific device and its supported commands. Incorrect usage of fastboot commands can potentially brick or damage your device.
