Problem

If you already tried resetting your device to factory default values with the reset button and you can't access the unit, we recommend that you perform a TFTP recovery.

• Do not switch off, do not reboot and do not disconnect the device from the power supply during the firmware upgrade process, as these actions will damage the device!

Steps

After your device responds to ping test,

Download and run tftp2 and configure it as in the image to upgrade.
