+## Update firmware
+
+An outdated version of the firmware can cause miscellaneous issues.
+Always ensure to run your device on the latest available version. 
+
+Via the Sunmi portal, 
+
+1. Go to **Device** > Device upgrade >Upgrade management
+
+2. Remove the data filter
+
+3. If there is new firmware available, the **Add to Upgrade Group** button will be highlighted.
+If there is no new firmware available it will be greyed out. 
+Adding a terminal to the update group means the terminal will detect new firmware and will start downloading.
+
+Tip: Make sure to unpack and activate the terminal so you can add it to the upgrade group.
+
+4. Download will start automatically. 
+By default, the download limit is set to 20KB/sec. You can increase this on the terminal itself in the **System update app**, ideally via the partner portal to apply it to all terminals. 
+
+5. Upon successful download, reboot the terminal to install the newly downloaded firmware.
+
+6. You can automate this in the partner portal via 
+Device > Device Upgrade > **Important package configuration**
+
+
+Steps on the device:
+
+1. **Reboot** via the button on right of the device 
+2. Settings (terminal) > About device > (select model)
+3. You can view your current version, and **check update**.
