adb reboot bootloader command is used to reboot an Android device into fastboot or bootloader mode. Fastboot is a protocol and tool used to re-flash the partitions on your device. It’s often used in conjunction with unlocking the bootloader or flashing custom firmware and recovery images.
Here’s how you can use it:
Connect your Android device to your computer via USB.
Open a command prompt or terminal on your computer.
Navigate to the directory where the ADB executable is located. This is often in the “platform-tools” directory within the Android SDK installation.
$ cd path/to/android-sdk/platform-tools
Run the following command:
$ adb reboot bootloader
After executing this command, your device should reboot into fastboot or bootloader mode, and you will be able to use fastboot commands to interact with the device, such as unlocking the bootloader or flashing custom images.
Make sure your device supports bootloader unlocking and that you understand the risks associated with unlocking the bootloader, as it may void warranties and can potentially result in data loss. Always refer to the specific instructions for your device and follow the manufacturer’s guidelines.
