When the firmware update fails, the first thing we suggest is restarting your phone or tablet. If that doesn't work, you can try the following steps to reset your MEATER Plus:
- Put the probe in the charger.
- Remove the AAA battery for one minute, then put it back in the charger.
- Take out the probe and wait for the LED to blink green.
- Open the MEATER app and start the update.
- While your MEATER Plus is updating, make sure the probe and charger stay right next to each other with your mobile device just a few feet away, and that the app stays open.
