I recently got a used rocket m2 from ebay. When it arrived i discovered that it was the XM version. I went through the install process like 30 times and cannot get it to work. This is probably the 20th node, and I've also used TFTP to flash Cisco and other devices, so i generally know what I'm doing but am probably missing something really obvious. I tried on several different computers, but Linux and windows. I can ping it, but I cannot get the TFTP client to send the file. I have the factory.bin file.
