Firewalla is a general computer with a full Linux distribution. (Pretty much like Raspberry Pi, if you know what that is). Many of our early supporters really wanted Firewalla system to be "open". Not only open source, but open to modifications, or at least giving some room to 'play'.
We kept our promise and left the SD card slot and made it user accessible.
We also uploaded the Final image to Github. Some of the cool things you can do
- Get a bigger / better SD card and you can actually do programming on the little thing. (Python, Node.js, and even GCC are already on the box!)
- Install things like 'tshark'. Which allows you to monitor all traffic on the network.
- A couple of our supporters expressed that they don't trust the shipping process, in this case, you can use your own flash and download the public image to it.
In case anything goes wrong you can use the build in 'Factory Defaults' to fix. But in case you got creative, here is the instruction to recover:
- If you own a Red Firewalla: Download the Firewalla Red Image Here
- If you own a Blue Firewalla: Download the Firewalla Blue Image Here.
- Download a flash program, we use etcher.io
- Note: etcher doesn't work on macOS Catalina (10.15), please scroll down for workaround.
- Take the flash out from Firewalla and use etcher to load the image.
- Put the card back in.
- Done as new.
- Go back to hacking!
After flashing (and before pairing with the app), you should still have an old icon on your phone. That's the 'old firewalla'. What you need to do is
- launch the app
- you should see the old Firewalla icon
- tap and hold on the Firewalla Icon, then the dialogue will popup
- tap on that to confirm, it will remove the previous pairing.

Known Issue: Etcher doesn't work on macOS Catalina (10.15)
Here is an open issue on GitHub etcher project to track this issue:
https://github.com/balena-io/etcher/issues/2833
Here is a workaround you can use before etcher fixes this issue.
- Open Terminal.app
- Run this command in the terminal:
- sudo /Applications/balenaEtcher.app/Contents/MacOS/balenaEtcher
- Type your MacOS login password when asked.

When Flashing device, don't forget to "Reset" the SSH password for your device as the default SSH password for image is not secure (and probably known).
There is no need to reset SSH password. The password will change itself after pairing. And will change itself once while. It also changes if you enter and exit support mode, and after each reboot.
I can't get my imac to recognize the microSD card that came with it using any means I have on hand. I had placed it into an empty SD adapter and directly into the SD slot on the imac as well as several different card readers. If I was to grab another card to put in here, what format should the card be before attempting to flash it with etcher?
Scott, if the card cannot be recognized, then the card is bad. For etcher to write a new card, formatting is not needed it, the program will dump a bit exact copy of the image
