How to update the firmware of a Zebra TC52 scanner?

- INTERNAL DOCUMENT, PRIVATE -

Place the Zebra scanner in the cradle and connect the cradle to the PC using a USB cable. Start 'Android' by swiping on the home screen. First, download the SDK platform tools: 

https://developer.android.com/studio/releases/platform-tools 

Extract this zip file into any program folder and then open a command prompt as 'Administrator'. Go to the folder where the platform tools are extracted and execute this command:

adb.exe devices

If the scanner is shown with the addition 'Unauthorized', start allowing USB debugging on the scanner. This is usually done by disconnecting (usb) and reconnecting the scanner. A notification may appear on the screen asking for permission to allow USB debugging. Choose 'Yes'.

If USB debugging does not work in this way, go to Settings. Choose 'About phone', 'Build number' (click 7 times), then developer mode will be enabled. Then check 'USB debugging' (System/Advanced/Developer options (enable complete option here), USB debugging).

The command 'adb.exe devices' should now display 'device' next to the found scanner.

Now give the command:

adb reboot recovery

If multiple devices are connected, you need to specify which device this is:

adb -s <DEVICEID> reboot recovery

The scanner will now reboot and enter a recovery menu. Choose 'Apply upgrade from ADB' (using the up/down arrow keys), confirm by briefly pressing the power button. Sometimes a submenu will appear with the choice of 'Full update' or 'No update'. In that case, choose 'full update'.

The scanner is now in update mode and will wait for data.

Now give the command:

adb sideload <update filename>

The filename is the zip file (do not extract the zip file).

Zebra firmware files can be found on box.

Translate the following text from nl-NL to en-US and use product instead of article and keep the html content: com \\Support\Zebra\

After uploading, the scanner reports 'Install from ADB complete', then quickly return to the menu. Choose 'Reboot system now' by briefly pressing the power button. Check if the update was successful:

- Swipe down from the top (swipe twice)

- Select the gear icon

- Scroll in the settings menu to the last item 'About phone'

- Check if 'Android version' has become 11

- Check if 'Build number' matches the uploaded file

At this moment, it should end with 'HEL-04'.
