Firmware files usually use the system model name with a "*.bin" extension, such as
"BM2022w.bin". The upload process uses HTTP (Hypertext Transfer Protocol) and may take up to
two minutes. After a successful upload, the system restarts.
Contact your service provider for information on available firmware upgrades.
Note: Only use firmware for your BM2022w’s specific model.
