How to flash new firmware from dd-wrt gui

I have a R6250 and successfully flashed v3.0-r28600M.  Seemed ok but I wanted to try Tomato, and tried flashing a tomato chk from the dd-wrt administration -> firmware upgrade screen.  After processing for just a second, my browser quickly went to a "page cannot be displayed" screen.  I had to a do a 30/30/30 reset, and then I was able to go back to and see the dd-wrt gui.  However, now when I try to save or apply any changes, it again shows me the "page cannot be displayed" screen, and the new settings are not taken.  I get the same result when trying to flash back the stock OEM netgear firmware.

I also tried to telnet to the router using putty on port 233, but it doesn't work... it gives an error "connection refused".  I've never used putty before, so I'm not sure if I'm doing something wrong there.

Any help guys?  Thanks in advance.
