Linksys WRT54GS v4.0
From DD-WRT Wiki
[edit] How To Flash
This is the process I developed based on comments left below. I was unsuccessful in flashing the router directly to the standard dd-wrt firmware, as some of the comments state is possible. I decided to err on the side of caution; I don't know if all of the resets are necessary.
Please, if this is the first time you're flashing a router with dd-wrt, read up on the basics before starting this process. You will avoid yourself a world of annoyance as a result.
- Read the Peacock Announcement
- Upgrade the router to the latest Linksys firmware (version 1.06.3). This can be obtained from the manufacturer's website or from our repository
- Perform a hard reset.
- Flash router with ths 14929 mini firmware
- Be sure to only use the WRT54GSv4 trailed build!
- Wait 5 minutes, then perform another hard reset.
- To flash to other firmware versions, flash a generic firmware that will fit on your router
- Wait 5 minutes and then hard reset again. Done.
[edit] Other Notes
The stock firmware from Linksys on the WRT54GS v4 won't accept a firmware image over 3MB in size (you will get the error: "Upgrade are failed!"(sic) if you try) so you will need to flash the mini version of DD-WRT onto the router BEFORE flashing the std or voip versions. (Remember to hold reset button for 30 sec after flashing mini version.)
DO NOT PUT FULL VERSION ON FIRST, i just did that and now my router is bricked:( make sure you do mini first guys!
