WRT54G - debricking after failed underclock

    I was having stability issues on my 2nd hand WRT54G v2.0 (DD-WRT v23 SP2 firmware)

    The router's previous owner seems to have overclocked it to 228Mhz (probably without any extra cooling, but i don't know), but I spotted this pretty soon and turned it back to 200Mhz right away, and there it stood for a few months. [he had put linksys firmware back on it to sell it on eBay, probably thinking the clock speed would reset with the firmware]

    I had checked the MD5 for the firmware, so i knew that wasn't likely to be the problem.

    I tried underclocking to 192MHz from 200MHz. http://www.dd-wrt.com/wiki/index.php/Linksys_WRT54G/GL/GS/GX#Clock_Speed_and_Overclocking says "t is also possible to underclock, which may be useful for troubleshooting crashes which may be caused by overheating" and doesn't say anything about it not being possible on a WRT54G v2.0, so i did it and it bricked.

    It does "turn on", the power light blinks forever and the LAN port connected turns solidly on, occasionally blinking. However, pinging on turning it on doesn't give any response.

    What I want to know is whether or not I should bother bridging pins or earthing pins to try to fix it as clock frequency seems to be independant of nvram (i don't understand all this CFE etc, i get the impression that its CFE that i've messed up from googling.) or what I should try or whether or not it's totally dead.

    I posted on the DD-WRT forum, but got no replies ¬_¬; I hope I'm posting in the right place on this forum.
