Method of updating firmware

摘要

A method of updating firmware for a product by downloading the updated firmware and automatically diagnosing download errors when processing customer requests to update the firmware. The method is provided by starting provision of the firmware file to a user device and receiving from the user device a first temporary file indicating a start of downloading the firmware file, and receiving from the user device a second temporary file completion or a failure of the download. It is determined whether the download of the firmware file is started and whether the download was a success or a failure by inspecting the received first and second temporary files and to rectify a problem that caused the failure of the download based upon the received second temporary file.
