I bought a router belkin F5D7230-4 ver.7000 and i'm trying to flash it and install on it the openwrt but it didn't works. i don't know whats going on? it could be that this router doesn't suport openwrt?

i'm doing this:
     1.Shutdown the router (unplug it from the power supply).
     2.  Enter the following at a Linux shell prompt;
           tftp 192.168.2.1
           tftp> binary
           tftp> rexmt 1
           tftp> trace
           Packet tracing on.
           tftp> put firmware.bin
      3.  Boot the router (plug it in to the power supply after it has been powered off for
          at least three (3) seconds).

thanks for helping me
