The new generation Davicom Cortex 360 units from Davicom are virtually “unbrickable” because the Davicom Cortex firmware can be re-installed from a USB image file.
The Davicom Cortex 360 also offers stress-free firmware upgrades. The dual-firmware memory slots allow users to roll back to the previous firmware version in case the upgrade creates problems with the current I/O configuration. Performing a firmware rollback recuperates the previous I/O configuration associated with the previous firmware version.
Firmware upgrade:

5- Select the file and click open to start the upgrade and wait until the unit reboots (3-4 minutes).
