Need help with recovery DSR-250N run command
« on: August 09, 2019, 08:30:44 PM »

Hello,

I have a DSR-250N that has the web interface inaccessible. I tried to load the latest firmware via the console port. I used the guide found at DLINK. All goes well until I try to use the run firm_flash command. The command interpreter seems to show a syntax error by showing usage examples.  The captured text file is below. Not sure what I am doing wrong. Hardware version is A2.

The guide I found on the UK Dlink website has some syntax mistakes. I used a guide in another post in this forum. It works. My DSR-250N works great.
