Technical Role in the Boot Process

The boot process is the sequence of events that occurs when you power on your Android device. Typically, the device’s bootloader initiates the process, checking for a valid operating system to load. If the bootloader detects issues that prevent the main Android system from booting (e.g., corrupted system files), it might automatically redirect to Recovery Mode. The bootloader then loads the Recovery Mode’s kernel and initiates its environment, offering a set of options to repair or restore the device.

This is how it generally works:
The bootloader identifies the partition containing the Recovery Mode.

The bootloader then loads the Recovery Mode’s kernel and its associated system files.

The Recovery Mode’s user interface is displayed, providing options to perform various maintenance tasks.
The user selects an action, such as wiping data or installing an update.
Recovery Mode executes the selected action, modifying the system files or user data as necessary.
Finally, the device either reboots into the normal Android system (if the problem is resolved) or remains in Recovery Mode for further troubleshooting.
