Hello. Do you know what Firmware Version was on it?

firmware 4.7.1 i think .

What device you use as TFTP servers ?

Hello @ahmed_ahmed_ahmed,

during recovery our radio will not respond to ping on any known address.
If you are using Windows PC, then disable firewall and anti-virus. They can prevent tftp to work.
Also you can Raise Ticket in right top of this page and our engineer will assist you.

Were you able to access the radio before the reset?
Have you tried using different ethernet cables?
