<li>This worked for me, but it’s no guarantee it’ll work for you</li>
<li>It’s been a couple weeks and I’m doing this from memory with the help of the resources I used, so I may have missed or misremembered a step</li>
<li>Read the relevant documentation for yourself

<li>DO NOT use the router database to determine the firmware version to use</li>

<ul>
<li>Recovery Mode (use Reset Button):
<ul>
<li>With router unplugged, press reset button</li>
<li>Plug in power</li>
<li>Hold reset button for ~10 seconds until the power LED is blinking slowly</li>
</ul></li>
<li>Clear the NVRAM (use WPS Button):
<ul>
<li>With router unplugged, press WPS button</li>
<li>Plug in power</li>
<li>Hold WPS button for ~10 seconds</li>
<li>Note: NVRAM is where the settings for the router are stored</li>
</ul></li>
<li>30-30-30 Reset
<ul>
<li>Push reset button with the router powered on for 30 seconds</li>
<li>Pull the power cord for 30 seconds while holding the reset button</li>
<li>Plug the power cord in for 30 seconds, while holding the reset button</li>

<h1 id="upload-via-web-gui">Upload via Web GUI</h1>
<ul>
<li>Tried using the Web GUI method, but ASUS firmware checks to see if it’s an official version (i.e. signed by ASUS), and will only install it if it is</li>
<li>DD-WRT isn’t an official version, obviously, but not all is lost, uploading via recovery utility works</li>
</ul>
<h1 id="upload-via-recovery-utility">Upload via Recovery Utility</h1>
<ul>
<li>Download router firmware: <a href="ftp://ftp.dd-wrt.com/betas/2015/02-04-2015-r26138/broadcom_K3X/dd-wrt.v24-26138_NEWD-2_K3.x-big-RT-N66U.trx">dd-wrt.v24-26138_NEWD-2_K3.x-big-RT-N6UU.trx</a>
<ul>
<li>big version includes more tools than mega version</li>
</ul></li>
<li>Make the following network config information on the computer you’ll upload the firmware from:
<ul>
<li>IP = 192.168.1.12</li>
<li>Subnet = 255.255.255.0</li>
<li>Default Gateway = 192.168.1.1</li>
</ul></li>
<li>Perform 30-30-30 Reset</li>
<li>Perform Clear NVRAM</li>
<li>Perform Recovery Mode</li>
<li>Navigate to 192.168.1.1 and follow screen directions to upload DD-WRT firmware</li>
<li>It may take up to 10 minutes to reboot (don’t think it took that long, but I waited that long)</li>
<li>Perform Recovery Mode</li>
<li>Navigate to 192.168.1.1 and select Reset NVRAM</li>
<li>Navigate to <a href="https://192.168.1.1/do.htm?cmd=nvram+commit" class="uri">https://192.168.1.1/do.htm?cmd=nvram+commit</a>, and then select reboot and wait ~10 minutes</li>
<li>Perform 30-30-30 Reset</li>
<li>Navigating to 192.168.1.1 should now bring you to your new DD-WRT installation
<ul>
<li>Remember to secure it</li>
</ul></li>
<li>Note: installing mini version (referenced in online directions) isn’t necessary prior to installing the big/mega version</li>
