The funny part about this blog is that I spent an entire day searching for how to do this and then I ended up landing on a blog post with the answer… written by ME. in this 2015 blog post Lol or something?
This tutorial assumes you are using Ubuntu and know how to access your terminal and do some basic commands. If not, do a quick study on that before you begin. If you aren’t using Ubuntu on your computer I’m not sure what I can do to help other than encourage you to switch immediately.
This tutorial also assumes that your computer/laptop is plugged directly into the DIR-615 router by ethernet cable and not by wifi. It could probably be done with wifi, but I don’t know and I know it adds an extra layer of complexity I don’t like. So find a cable and plug in to do all this.
1. Download the appropriate image from OpenWRT to your computer.
I got mine by refining a search here.
2. Extract the file into it’s raw ‘.bin’ format.
Mine looks exactly as follows at the time of this writing when it’s sitting in my directory but as versions change and improve this could slightly change be aware:
3. Using your terminal cd (change directory) to the location where the file is you just extracted in step 2.
4. Make sure your computer is set to a static IP address.
If you don’t know how to do this, search it online as I don’t have a quick link to it right now. “How to set static IP address in Ubuntu’ should find something. Make sure that your static IP address you are setting does not conflict with another device on the router, nor with the router itself at 192.168.0.1.
NOTE: After this router is flashed you will need to get rid of this static IP address since it won’t match your new router!
5. Pre-enter the following command into your terminal so you are ready to press enter
curl -0vF firstname.lastname@example.org http://192.168.0.1/cgi/index
Again, the part after the @ symbol in the command above might change depending on the .bin file you are flashing on. This tutorial will likely get old at some point so you may need to swap out a different file name into the command above but the rest should work long term.
6. Power off the router by unplugging the black power cable
Warning. You are about to forever wipe your router’s ‘operating system’ so if you have anything in there you care about this would be the time to get those out!
7. Put pen in the reset button of router and hold it there
8. While still holding reset button, plug in the power cable.
Keep holding the reset button! Don’t let go. The light will be a solid colour (orange, I recall?) but you are waiting for the first flash before executing the next step.
9. As soon as the solid light starts to flash hit the enter key in your terminal and run the curl command you pre-entered in step 5 above
After you hit this command at the perfect moment, things should start to work. When they do, you’ll see some funky html stuff come on the screen that looks like this:
* Hostname was NOT found in DNS cache
* Trying 192.168.0.1…
* Connected to 192.168.0.1 (192.168.0.1) port 80 (#0)
