Cortex 360 Rescue Procedure

The new generation Cortex 320/360 units from Davicom are virtually “unbrickable” because the Cortex firmware can be re-installed from a USB image file.

The Rescue procedure to re-flash the Cortex 360 memory with a USB image key is used if the unit becomes unresponsive and you are unable to connect.

CAUTION: Do not install or remove the USB image key when power is connected to the Cortex 360.

Re-flashing the Cortex 360 unit with a USB image key

  1. Download the image file from the Software & Firmware page:
  2. Burn the image to a USB thumb drive using freeware utility Etcher, available at
  3. Disconnect power to the Cortex 360.
  4. Install the USB thumb drive with the image file in one of the USB ports on the rear panel.
  5. Re-connect power and wait until the OLED display shows the menu selection for re-flashing.
  6. Confirm the firmware re-flash and wait until the “memory re-flashing done” message appears.
  7. Disconnect power and remove the USB thumb drive.
  8. Re-connect power and wait until the unit reboots.
  9. Using the front panel display and arrow buttons, re-enter your IP Parameters.
  10. If you have a copy of the configuration file, connect to the Cortex 360 and reload the file.

NOTE: The APNS certificate for iOS must be re-installed after a Rescue re-flash procedure.
