The command "fastboot reboot bootloader" is used in Android devices to reboot the device into the bootloader mode.
The bootloader is a program that loads the operating system kernel and other essential files during the device's startup process. It is responsible for initializing the device's hardware components and preparing the system for booting.
In certain scenarios, such as when unlocking the bootloader, flashing a custom recovery, or installing custom firmware, rebooting the device into the bootloader mode is necessary. The bootloader mode allows the user to interact with the bootloader and perform various low-level operations on the device.
By executing the "fastboot reboot bootloader" command from a computer with the device connected via USB, the Android device will reboot directly into the bootloader mode, giving the user access to perform various bootloader-related tasks.
