downgrade Android version in Zebra tc57

expand collapsive

Need some help!… Our retail stores have Zebra mobile devices for workers to communicate and coordinate their work. We want to downgrade the devices that are on Android 11 to Android 8. Our in-house inventory app is most stable with Android 8.  Our newer devices are updated to 11. Our team is working on a stable version of the app for Android 11 with a new framework. Until then we need to run the old app on all devices with Android 8.
We have all of them enrolled in the portal in Device Owner android Enterprise.
Can we do this from Hexnode?… Thanks in advance!

  • Hey @KeiR!

    We definitely have a solution that suits your requirement. Hexnode supports downgrading OS versions on Zebra devices via the OEMConfig app. An OEMConfig app provides zero-day support for new features before EMMs integrate them. Follow these steps to deploy the OEMConfig app to your devices and downgrade the OS:

    1. Add the Zebra OEMConfig app to the Hexnode App Inventory by approving it as a Managed Google App in the Apps tab.
    2. Push the Zebra OEMConfig app to your devices using Install Application action under Device Actions or associate the app to your devices as a Mandatory App with a policy.
    3. Navigate to App Configurations under App Management in Android in the Policies tab.
    4. Click Add new configuration and select Zebra OEMConfig app.
    5. Zebra OEMConfig App

    6. Scroll down to the section Firmware over the Air Configuration.
    7. In OS Update/Upgrade/Downgrade File, specify the file (ZIP, UPL, XML, etc.) to be used if either of the options OS Update, OS Upgrade, or OS Downgrade is chosen for Mode Manual Action.
    8. Ensure that the file is already contained on the device file system at the specified location.

    Downgrade OS with Zebra OEMConfig app

    In the future, if you wish to update your OS, you can schedule OS updates on your devices enrolled in Android Enterprise as ‘Device Owner’. You can choose to postpone updates or update while the device is not in use.

    Hope this answer helps you.

    Thank you!

    But from Android 9 google add mandatory rollback protection from downgrade OS and only security patches can be downgraded after this.
    Is this method working now?
    Officially, zebra said that’s impossible.
    We need to downgrade ours tc52 from A10 to A9 too…

  • Hello @Jack,

    Hope you are doing great.

    Well, it turns out that you’re right in this regard. As per Zebra, the Downgrade OS operation works only on devices with Android versions < 8.0. Therefore, you may not be able to downgrade your devices from Android 10 to Android 9.

    If there’s anything else I can assist with, please let me know.
