How to update your device’s firmware on iPhone/IOS
Step 1: Make sure your Mio device isn’t paired with your phone.
Go to your phone’s Bluetooth settings where you’ll see a list of nearby Bluetooth devices. If you see your Mio appear under My Devices, tap the ‘i’ beside its name and select ‘Unpair’ or ‘Forget’.
Step 2: Close the Mio GO app.
Press the home button twice and swipe up on the Mio GO app to close it.
Step 3: Make sure you are using the latest version of the Mio GO App
Visit the App Store and update your Mio GO app to the latest version. If you have the latest version of Mio GO, open the App now.
Step 4: Update your Mio device firmware.
Open the Mio GO app and connect to your device. You will get a message to update the firmware. (If the GO app doesn’t ask you to update, you can manually update firmware in Mio GO by opening the Mio GO app. From the top left menu, select “Help” then “Software Update.” Select your Mio device and update.) Select OK and follow the prompts.
Step 5: Firmware update successful.
After the update, a message that the firmware has been updated will appear. Your Mio device will now be working normally
Troubleshooting tip: If the update fails or takes longer than 5 minutes, go to Step 2 and repeat the process.
