Explanation
Verifying the device is fully charged and connected to a stable power source is the single most critical pre-firmware-update step. If the device loses power mid-update, the firmware can become corrupted and brick the device - a potentially unrecoverable failure. Adequate storage (B) and admin access (C) are prerequisites but failures there are recoverable. Exporting settings (D) is good practice but not as critical as power stability, since settings loss is far easier to recover from than a bricked device.
