<alertbox> WARNING: If you make a mistake installing this software, it is possible to permanently disable your router, effectively turning it into a brightly colored brick. Bricked routers aren't very useful – you can use one to beat someone about the head or as modern art, but that's about it. You can pretty much eliminate this risk by following the directions given here so please read them first before attempting to install Gargoyle.
Gargoyle is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. The author(s) of Gargoyle assume ZERO liability for any damage caused by this software.
Check that your Router Hardware meets the minimum requirements.
The recommended way to install Gargoyle is to Download the correct Gargoyle factory.bin image to your PC and then install the image onto your router using the original manufacturers GUI.
Check the exact version of your router hardware carefully before selecting the download. Gargoyle images are available for many routers.
If you get the error message “please choose a file to upgrade”, then rename the firmware file to something shorter (i.e. “gargoyle.bin”) and upload it again.
Installation instructions are available for several models:
To get started you will need a wired connection from a PC to a LAN port on the Gargoyle router:
OpenWrt defaults to having no root password and telnet is available. Telnet is not available on Gargoyle installed from an image.
Can you flash directly to Gargoyle from an OpenWRT install??
It may be possible to install OpenWrt Kamikaze and then install Gargoyle as a set of packages on top of it. Gargoyle is now based on Backfire and theoretically installing as a set of packages should work, but it possible it may not.
Attempts to load a Gargoyle image directly from the DD-WRT GUI have been unsuccessful. However, downloads are available to revert from DD-WRT to Stock Factory firmware, and from there a Gargoyle image may be loaded.
If you find the documentation here insufficient there are several other resources on installing OpenWrt you may find helpful. In fact, much of the information provided here was derived from these sites:
