Need help wtih recovery

[Gamerayers]

I did something which caused a total failure of the device. It was about 5+ months ago, so I can't say exactly what I did. But when I try to boot into recovery using serial, I get "Error: ethernet@1b100000 No valid MAC address found.".

I have a new RT3200 and was able to download the mtd0-3 from it, and using HxD edit the serial and MAC addresses. That said, I am struggling to understand how to get these files on to the device since I cannot connect using WinSCP since the device doesn't seem to have an MAC so no IP. It appears I can connect a USB device to it, but I have yet to figure out how to mount the device and then use it to load the files. I've tried a couple different methods of sending the data over serial, but yet to figure out how to do that either.

Is there a way to mount the USB? Is there a better way to send the MTD0-3 to start recovery? Any help would be appreciated.

I the Uboot menu choose
0. U-Boot console
or hit ESC to get into the console

Example, find your correct mac on your sticker

env set ethaddr 7a:8f:05:b4:aa:bb
dhcp

with some luck, you may have a network
