    Hi ,
    I am a newbie and have been browsing through the posts and have yet to find a definitive guide to help someone cut through all the different versions and what to flash for which model. I'd like to start this thread for future newbies like myself, hopefully with the help of everyone here.

    I will start by telling what I find most confusing :

    1. For someone who comes with a WRT54G (eg any ver 1 to 3) , does he need to install hyperwrt 2.0 vs 2.1b1 (also what does rupan's version do and when to choose rupan's fw) before installing Tofu (any version) ?

    Actually, is it a requirement to install the hyperwrt 2.0 or 2.1b1 before installing tofu or thibor or can we just skip that step and flash our WRT54G(s) (whatever linksys fw is loaded) with either tofu or thibor directly onto our WRT54G ?

    The same question for someone with a wrt54gs before installing thibor (I figured that much that u needed thibor for a wrt54gs although I saw that questions asked ad nauseum)

    2. if affirmative in question 1, how does he decide which tofu version to install next ?

    3. Can things go bad during those installations and can you end up with a brick ?

    4. Is there a cheat sheet to debrick in case u run into issues during flashing with hyperwrt (2.0 or 2.1b1) or tofu (6 to 11) ?

    5. I see a lot of mention about clearing memory, what happens if in the middle of upgrading the fw, lan ports connections are lost (ie lights stop blinking ).

    I have also seen a lot of mention of flashing dd wrt v23 mini generic (sept build) first before flashing to thibor. Does that mean skipping installing hyperwrt 2.0 first and in what circumstance would u flash dd wrt first ?

    Thanks all for your feedback. I hope this might clarify things for everyone new to this forum.

    1. You have a WRT54G so if you are considering the HyperWRT firmware, you'll have to use the Tofu builds as they are for that series of router. The Thibor series are for the WRT54GS series.

    Prior to installing the Thibor series (and I'd assume it's the same for Tofu) download and flash your router using the dd-wrt mini version.

    Give a wired machine a static address that falls into the range (so, with a subnet of and a gateway of

    Restart the router and when it's coming-up tftp the firmware image (.bin) file to the router using the following command (in Windows):

    tftp -i put image_file_name

    Make sure you do it right after plugging the power cable back in to the router as the image has to be transferred within the first few seconds while the router is listening on (default).

    2. Always try the latest build. At the time of this writing it's Tofu11. You can get it here.

    3. Definitely. Flashing your router with third party firmware revisions is not supported by Linksys as it can cause a "brick" where your router will not respond. There is a helpful de-bricking guide here provided by the HyperWRT developers. Just so you know, I've used every brand of after market firmware and have yet to brick a router. Just be careful with each version and do your research before doing anything drastic.

    4. See point 3.

    5. Losing connectivity during flashing is the most common way to brick a router. It's also the most unlikely way of causing a brick because if you follow my advice in point 1 there is no reason that you'll lose connectivity (within reasonable limits, obviously, if something can go wrong it probably will). Just make sure that everything is fine between your wired machine and the router before doing anything.

    I would recommend the dd-wrt mini version as opposed to the older HyperWRT versions. Not sure why exactly, but it's what the developers recommend so I heed their advice. ;)

    Hey, purephase, excellent post.

    One minor correction - to load Tofu on a WRT54G, you simply load it from the GUI in the stock firmware, using the standard "update firmware" tool. Then erase the NVRAM, reboot it, and follow the menus to reset factory defaults.

    My WRT54G V4 went straight from Linksys stock firmware to Tofu 10 with no DD-WRT middleman. Easy as you please.

    I would load tofu on your router. Download the bin file, it will come as a zip and you will need to unzip it...

    Then go to your admin page and click the browse button on your update firmware tab.

    Click okay or run.. And let the magic happen.

    All should be good and painless.

    Hope that helps, mate...

    Thanks for the information. I have the GS model so I've never flashed a G-series router.

    Watch moving from Talisman (at least, the latest devsnaps) as the web upgrade section appears to be broken (not sure if this is on purpose or not) and the only way I could get back to HyperWRT was to tftp the dd-wrt mini release (22.12.2005) during powercycle.
