Sunmi Update Instructions

1

Get the device serial number

Before a software update can be pushed, the SUNMI device serial number (SN) must be provided to us.

To find the serial number on the device:

• Go to Settings

• Select About Device

• Locate and send the Serial Number (SN)

2

Request the software update

Once we have the serial number, we will submit an update request directly to SUNMI for that specific device.

The update must first be approved and pushed by SUNMI — it will not appear on the device until SUNMI has released it to that serial number.

3

Confirm the update is available

Once SUNMI confirms the update has been pushed, we will let you know and advise you to proceed with the installation.

4

Install the update on the device

To install the update:

• Open the Software Update / System Update app on the SUNMI device

• Increase the download speed to Maximum

• Check for updates

• Start the download and installation process

• Follow any prompts to reboot the device once complete

SUNMI documentation also references using the System Update app to manually download and install OTA updates once the device has been added to the upgrade group.

5

Confirm completion

Once the update has completed successfully and the device has restarted, please confirm back to us so we can verify the device is fully updated.
