    I managed to brick my wrt by Power on / Power off the router.

    so fast-blinking power led is the result.

    after read some forum, I think need I use the JTAG cable to fix.

    but I don't know what software I need, and how to make the JTAG cable ?? I just know the router Ver is 3.1 with official firmware, and the JTAG port have 12 hole.

    So now , can anyone with knowledge of the jtag utility / cable.

    PLEASE help me ....................

    Have a look at here.
    Check the last post from "ranvik".
    Download the first ( and second file (CFE.bin.......)
    Second file is important for you because it's exactly for your router.
    Unpack first file and there you can find folder called windows.
    In ReadMe.txt is explained what to do. Just read it properly.
    There is also drawing (.png file) how to build JTAG cale.
    Also i would recommend you to read this stuff.
    From Linksys webpage download the original firmware for your router and rename it to code.bin

    It's not hard to debrick it, but it easy to kill it.
    So be carefull. If you're not sure what to do, just ask.
    I would also recommend to make printscreens and post them here with your questions.

    Good luck mate. :thumbup:

    PS: i've got package which i used to unbrick my wrt54gl v1.1. there is everything what was necessary for my. Also i wrote some HotTo. So have a look at it here.

    If you having trouble to download it, send me your email address and i will send it to you.
