Strange RouterBoard 951G 2HnD recovery

RouterOS General
1

Good day.
I got one RouterBoard 951G 2HnD.
All works well except one of the ports (No.2) - it does not work, so in first I tried to reset the device to factory defaults by pressing reset button with power start.
After that, it booting well (with one and two beeps), but doesn’t ping 192.168.88.1 address (with port No.1 connection).
Next, I tried to flash device by netinstall utility. It sees the device and successfully flash it for new RouterOS packages but after flashing reboot the device does not ping for its default address (192.168.88.1) on port No.1.
I acted according to this article: https://tushev.org/articles/blog/16/how-to-recover-un-brick-your-mikrotik-rb951g-2hnd-router

Here some screenshots of netinstall. I am embarrassed :frowning:

  1. Default configuration assigns 192.168.88.1 to ports 2-5 (and port 1 has dhcp-client running and no default IP address assigned).
  2. Your screenshot shows you’re trying to flash 5.26, which may not work as expected unless your device is old and was originally shipped with 5.x factory-installed.
  3. Have you tried connecting by MAC?
