GL-MT2500A completely bricked?

HI all,
I was using my Brume2 G:-MT2500A as Wireguard client connected to remote master location. After one year of good service box stopped responding. No change was done, no FW update nothing. Just disappeared from the internet router and devices connected to it list VPN connectivity.

  1. I tried to connect to it directly from laptop via cable - nothing -> systems shows no network connection.

  2. I tried the reset via button -> not successfully.

  3. I tired uboot recovery -> router was sucsessfully switched to recovery mode, but connection from laptop to boot interface was not successful, again no device connected, I switched from LAN to WAN port and repeated sequence with same result.

For me it looks like Ethernet port are KO.
Here are details for the router:
Device details:

  • Model: MT2500
  • Firmware: 4.6.2
    I will appreciate any help.
    Thank you.
