OK i’ll post the status of my problem (life happens so it took me a while to go back to my problem)…
1.- Since i had my NAS conected via a switch i connected it directly to my modem, i then looked for the password of said modem since i had never opened its setup page
2.- Went to LAN setup and noticed “MyCloudEX2Ultra” appeared in the “attached client list” with its respective IP Address.
3.- Copied and opened the IP Address.
4.- Voala! the webpage said that my device was running in safe mode, so i downloaded OS 3 firmware and installed it.
5.- NAS is up and running, although i don’t remember my password i think hard reset will restore everything to factory-like.
Thnx for the help man c: now my NAS is back and running.
