As noted in the K40 series user manual, “If you need such upgrade file, please contact technician. Usually, firmware upgrade is not recommended”. This is ZKTeco’s standard safety caution. Contacting your local distributor or ZKTeco’s official support team directly allows them to verify your device’s before providing the correct file. This method is the gold standard for “extra quality” as it guarantees the firmware is both genuine and appropriate for your specific hardware.

A legitimate file will come with an MD5 checksum. Before flashing, use a tool like HashMyFiles to verify the integrity. If the checksum does not match ZKTeco’s provided hash, do not install.
