    I used a jtag cable and erased the memory, installed a cfe, all of this seemed fine. Now when I power the unit the power led flashes. I can ping it, I can use TFTP to transfer a firmware (using the one from Linksys's Website) and it seems to complete ok (the number of blocks matches the file size at least) but nothing happens. the power led stays blinking, and eventually when I reset the power to the unit the power led still flashes and I can still ping and tftp to it. Does anyone have any ideas on how to revive this unit?

    perhaps a little more background could help us help you. Why in the world were u using a JTAG cable and installing a new CFE? Here, there's no such thing as giving TOO MUCH background information ;)

    Well I screwed up the firmware with a bad flash, and read about the jtag cable as a way to flash the chip again, following the directions I got to the point where I can tftp (as I said) but nothing happens, everything else behaves as it should (or as others on various forums say it should).

    personally I've found that sometimes that the hardware can be VERY fickle, and one must hold the reset, power it up and down, and almost every other trick in the book to sometimes revive these things... I had a v4 that I thought was permanently bricked, but through some coaxing and a combination of the aformentioned tricks, I got it up and rocking again...

    I logged the serial port and the cfe says ( I removed the MAC address):

    mac_init(): Find mac [] in location 0
    Nothing...
    Device eth0: hwaddr -----, ipaddr 192.168.1.1, mask 255.255.255.0
    gateway not set, nameserver not set

    Just so the answer is here:

    It turns out there were one or more pins on the flash chip shorted together, a magnifying glass and dental pick cleaned up the whole issue.
