    I'm running DD-WRT v23 SP1 Final on a WRT54GS v2.0 (0.7rev CPU) and tried to overclock to 280MHz and now the unit won't reboot. Power light just flashes. Can someone tell me what I need to do to recover this unit? If you give me an answer like jtag it or something then please give me a link or more info then just that, thanks.

    In the command prompt, can you ping the router?

    Use "ping" and enter, unless you changed the routers IP.

    After I first upgraded to dd wrt v23 sp1, I fiddled with the OC feature on my WRT54G v2.0 and just nudged it to 216mhz and the router's power light just flashed, couldnt get to the web admin.

    Stonecat sent me this link:

    Thats for WRT54G routers, but looking at yours here:

    It seems you would have a similar bios chip, and if you can't ping it, you may want to try some of those revival tips.

    And if you can ping it and you have the original CD, there should/may be a setup wizard program on there that you enter the router's IP, password, and the firmware,or it may have the firmware in the wizard and only ask for IP and pass, then it'll upgrade it.

    If you have a choice still flash a real linksys firmware, thats the only way it worked for me, Hyper and dd wouldnt flash from the setup wizard

    afaik JTAG will be the only method though I did see somewhere here about placing the WRT in the freezer, this allows the unit to be overclocked due to heat issues. as soon as its boots you need to reset the clock frequncies however.

    Overclocking a WRT is not like overclocking a CPU. if it crashes you wont get the unit back without alot of hard work. tbh i think htere need to be a maximum overclock speed of about 230 ish tbh to stop this sort of behaviour.

    Well I had it running fine at 264 for over 2 weeks before I tried 280 and I have heatsinks on pretty much everything in there and the case over top was off.
    I tried the freezer things previous to the original post and it didn't help. I think at 280 it's just a case of the cpu can't do it, not a heat issue.
    Time for jtag, going to put the header in soon and then I won't have to worry about bricking anymore. No need to restrict clock freq. I knew the risk before doing this. Guess I may as well put the serial header in at the same time, I always gotta mess with stuff.
