Power Source: Always ensure your device is connected to power or has at least 50% battery to prevent a shutdown during the flashing process [5, 16].
Root Directory: If using a USB or SD card, placing the file in the "root" (the main folder, not inside another folder) is usually required for the device to "see" the update automatically [5, 12].
