What does the advanced reset option allow regarding firmware downgrades?

The advanced reset option specifically facilitates the ability to downgrade a SonicWall Secure Mobile Access (SMA) device that has undergone a Return Merchandise Authorization (RMA) process. When an SMA device has a firmware version installed that is higher than the firmware version that was previously used, this option allows administrators to revert the device to an earlier firmware version that was operational prior to the upgrade. This is crucial for troubleshooting issues that may have arisen due to newer firmware versions or if there is a need to align with a specific operational requirement that is only compatible with an older firmware release.

The other options do not provide the same functionality. For instance, downgrading beyond a specific version may not be supported by the device, and reverting to only the last updated version limits flexibility in addressing specific firmware-related issues. The option to remove installed applications, while relevant for maintenance, does not pertain to firmware management and does not address the broader concern of device stability and operational consistency compared to previous firmware versions.
