Firmware can be updated using the Reflash option in the ReXdesk Software.

The latest firmware can also be located here:

C:\Program Files (x86)\Influx Technology\ReXdesk\Firmware\RexFirmware.zip

**Notes:**

* While re-flashing, the device's LEDs will flash alternatively; do not disconnect or change the power source during this process.
* The device will disconnect from the PC while it is re-flashing. It will automatically reconnect once re-flashing is completed.
