    I tried following that as close as possible but didn't work either. Then I tried TFTPing the firmware and although the transfer completed, the router still came up on Tomato.

    So going back to my experience long ago with my Motorola WR850G firmware which had a header which needed to be stripped off, I pulled up the Tomato firmware and compared it to the Linksys firmware. The Tomato firmware started with the string "HDR0" and I found that same string 33 bytes into the Linksys firmware.

    So I stripped off the first 32 bytes of the Linksys firmware after which I was able to revert back to it fine.

    Then I loaded Tomato again successfully. The only minor glitch was I was not able to restore my backup configuration - got an error "Invalid signature: {8 digit hex number} / {8 digit hex number} Please wait while the router reboots...". But I was able to reconfigure it manually without issue, create another backup and reload it.

    FYI I removed the header on my Ubuntu laptop using the tweak hex editor. Could have easily done the same with HDD or other hex editor on Windows. Could also have done it with "dd" on Linux/Unix like:
    Code:
    dd if=FW_E1000_1.0.01.007_US_20100415.bin of=FW_E1000_1.0.01.007_US_20100415.stripped.bin ibs=1 skip=32

    So, nobugme. Just curious if you tried this and how it worked out for you.
     
  6. It does work but i didnt try it myself i posted this same question in dd-wrt forums and got a answer quickly. A guy there edited a dd-wrt firmware for me.

    OK, glad you got it fixed. So guess you're back to stock now? Never did quite understand why you wanted to, heh, but glad you got what you wanted.

    fixed finally - finally got the firmware to upload over Tomato.Raf by using a hex editor and removing the first 33 byte of the file, with assistance from this link :
    So I stripped off the first 32 bytes of the Linksys firmware after which I was able to revert back to it fine, which one, you may ask.
