How to update externally via an SD card – Help Center

1. Contact technical support to obtain the firmware update file

2. Update steps:

1. Format a MicroSD card of no more than 32 GB as FAT32.

On a Windows PC, right-click the SD card → Format → select FAT32 (default) to format it.

2. Place the downloaded “update.zip” file in the root directory of the MicroSD card.

The file path should be: MicroSD card name > update.zip.

3. Open the SD card slot on the OttoAibox device and insert the MicroSD card.

4. After the OttoAibox powers on and detects the SD card, a window will pop up. Please select “Upgrade”.

5. During the update, the red and blue indicator lights will blink alternately. If the device is connected to a TV or other device, do not turn off the power or stop the process during this time.

6. When the update is complete, the device will restart automatically.

7. After confirming that the device has started up, turn off the OttoAibox power and use a SIM ejector pin to remove the MicroSD card.
