Resetting Tomato Configuration

    Hello there,

    I am trying to wipe a Linksys WRT600N that was setup with a Tomato Firmware. I can't seem to access the web interface for it, nor trying to do a 90 second reset seems to work. I can't even get it to clear out the old settings so I'm pretty much stuck trying to wipe it clean for another person. Anyone have any suggestions on what I can do short of using a hammer or other strong instrument and destroying it?

    The dd-wrt site has some documentation how to Recover from a Bad Flash. From some threads I read, you might want to start with a power cycle of the router. Then, after it boots, then do a hard reset (30/30/30).

    Well, here is the problem. I can't seem to telnet to the router, which the recover from a bad flash indicates I should be able to do. I tried tftping the original firmware of the router back onto it, it restarted and still has the tomato firmware and settings when it restarted. And as I stated before, I tried to do a hard reset, the 30/30/30 and it still came back up with the old settings, not the baseline settings. So running out of ideas here.

    I should also clarify, the router is not a brick... At least, not yet. I just can't seem to access the management for it, or get it to reset back to the firmware's base settings, which is what I need to do before we get rid of it.

    I tried that one as well:

    -Follow these steps exactly. Make sure to have a pen handy to reset the router.
    -Plug in the router. Watch the pings. When you start receiving packets from the router, press Enter on TFTP. TFTP should connect and send the stock Linksys firmware.
    -When the firmware is sent, wait 5 seconds, then hold down the RESET button on the router with a pen. Keep holding it down until the router reboots (30-40 seconds). Hold it down for another 30 seconds after that.
    -The NVRAM should have been cleared. In this case, the unit's Wireless LEDs should turn on. Give it a couple minutes to settle if necessary, then it should assign your computer an address with DHCP.

    (About here is where I was trying to get, as I was not planning on reloading a different firmware like DD-WRT or Tomato onto the system.

    -Reboot and flash the WRT600N mini version specifically made for TFTP within 5 seconds of boot. (You can find it on the router database). Use the commands I mentioned above for TFTP as well. This version of stock firmware cannot be easily flashed from within the web interface.
    -Wait 5 seconds after TFTP finishes. Hold the reset button until the device reboots.
    -Flash the Mega version with the web interface. Reset factory settings after you flash just to make sure everything's cleared.
    -You're done! Not only is your device unbricked, but it's running the latest version of DD-WRT as well!

    Should I have tried the above? Remember, I am not trying to recover from a bricked situation, just wipe the router back to a baseline situation. From what I can tell, it has the settings the router was configured with, even the unnecessary setting of the LAN part at 10.1.1.1 (For the router) and the wireless SSID showing up.

    When I got my second hand WRT54GL I couldn't reset the nvram either. Actually the router would show some part of the webinterface, but no password worked and resetting didn't clear it. Only after I had used the tftp solution I could log in again. So that's why I would advise you to use this solution. Just be careful and keep in mind that this solution needs good timing to work. It took me some reboots until it flashed at the right time.

    Finally, success... I just had to take it a step further by having it active after the first attempt, force tftp the firmware again and then try the reset procedure and hold down again... Now I got it back to factory firmware specs again.

    I had a similar situation as well long ago with either a WRT54G or WR850G, can't recall which. It wasn't bricked but wasn't really usable. This was when I was still using DD-WRT on it. I tried a lot of fixes and was getting very frustrated. Ended up TFTPing OpenWRT to it which brought it back to life. After that I was about to reload DD-WRT, and later Tomato, with no issues. Have never seen such an issue since. Best I can tell some weird hiccup occurred which resulted in a corrupt flash - not bricked but unusable. No way to be sure if you have the same issue, just sharing my experience.

    Well, I found out later that the person who worked on the router before me, was trying very hard to make it secure for the environment he was putting it in. Which is great. Except when you have to dispose of it.

    In an Enterprise environment, most people need to clear out possible networking information on computers and the like to avoid compromising issues, and without documentation it made it difficult to wipe it clean short of having to resort to physical damage, which is not the most ideal way to get rid of a perfectly good router.
