HOW-TO GUIDE

Updating d3kOS

There are two ways to update: OTA (over-the-air, T1 and above) and manual image replacement (T0 or recovery).

T1 · T2 · T3

Method 1 — OTA Update

Over-the-air updates download and install directly on your Pi. No microSD required.

1
Open the d3kOS dashboard on your Pi
Connect to your Pi's IP address in a browser on the same network.
2
Tap Settings → System → Check for Updates
The system checks AtMyBoat.com for the latest version.
3
If an update is available, tap Install Update
The download runs in the background — approximately 5 minutes depending on your connection.
4
Tap Restart to apply
The Pi reboots once. The dashboard will be unavailable for about 2 minutes during restart.
5
After restart, verify the version in Settings → About
Confirm the version number matches the latest release.

T2 and T3 automatic updates: OTA updates install automatically on T2 and T3. You will see a notification banner on the dashboard when an update is ready.

T0 · Recovery

Method 2 — Manual Image Replacement

Use this method if you are on T0 (no OTA) or if your Pi will not boot after an update.

1
Download the latest d3kOS image
Go to /download and download the current release (.zip file).
2
Flash to a fresh microSD card
Use Raspberry Pi Imager (recommended) or Balena Etcher. Select the .img file inside the zip.
3
Swap the microSD in your d3-k1
Power off the Pi, remove the old card, insert the new one.
4
Power on and run the 20-step setup wizard
The wizard runs automatically on first boot.
5
Re-enter your configuration
T0 has no cloud backup — note down your settings before flashing.

T1, T2, and T3: Your voyage history and settings are preserved in the cloud. After flashing, pair your device at /pair-device and everything restores automatically.
