Firmware Updates
Occasionally the firmware in the various components may have to be updated. You can be notified of this in one of two ways:

1. You may get a popup window telling you that a firmware update is available and asking for permission to proceed.
2. You may see a red dot appear on the menu icon in the top left corner of the screen. Clicking on the menu icon opens the menu which will have an alert at the bottom letting you know a firmware update is available. You can tap on the alert and be taken to the beginning of the update process.

You may get this popup telling you that a firmware update is necessary If you are ready to proceed, tap on the "I Have Read and Understand" button.

You may be notified of a pending firmware update with the little red dot on the menu icon in the upper left hand corner of the "Now Cooking" screen. Tap on the menu icon.

You will see an item in the list in red telling you which device needs the firmware update. In this case, it is the 4X Charger. Tap on the notice in the list of options.

Note that if you get the popup, you will not be able to use your probe until you perform the update as there is no way to refuse the update and go back to normal operation. You should turn on your MeatStick 4X probe before you intend to use it and allow enough time (up to 5 minutes) to perform the update before you cook.

What we are about to show you is how the procedure works for the 4X Charger. The MeatStick 4X probe procedure is very similar. Also it may be different on an Android device. However, the following should give you a good idea of how to update the firmware.

Step 1. You are instructed to place your phone next to your 4X Charger, not to move either device and not to leave the App during the process. Tap on "I Have Read And Understand."

Step 2. You are instructed to press the button on your 4X Charger and hold it for 5 seconds. Do so, then tap on "I Have Read And Understand."

Step 3. You are asked to allow the 4X Charger to pair with your phone. Tap on "Pair".

Step 4. The firmware update will begin and you will see the progress bar crawl across the screen. Do nothing during this process.

Step 5. You are notified that the process is complete. Press the button on the charger/extender as instructed, then click on "OK".

Here are a few more notes about the firmware update process:

1. If you have multiple probes, each probe must be updated, one at a time.
2. Other devices like the WiFi Bridge and your MeatStick probes must be updated separately, although there may or may not be a new firmware level available all at the same time.
3. Firmware updates are never started without you having to take a specific action to start it. So you will never have a probe update itself in the middle of a cook.
