With minor effort, you can have the best of both worlds – the features of Xiaomi EU and full app compatibility. Whether you’re new to custom ROMs or a seasoned modder, read on to resolve “Device not Certified” and unleash the full potential of your rooted Xiaomi phone.

Resolving the "Device not Certified" Error After Flashing Xiaomi EU ROM

How to fix the “Your Device is not Certified” error on Xiaomi EU ROM

The “Your Device is not Certified” error is common when installing custom ROMs like Xiaomi EU on Xiaomi devices. This error prevents full access to Google Play Services, including key apps and features like Google Pay, Netflix HD streaming, and Pokemon Go. Fortunately, there are a couple straightforward steps you can take to recertify your device and resolve this issue.

Solution 1: Clear Data for Play Services Apps

One simple potential fix is to clear the data for the main Google Play services apps:

  1. Open Settings and go to Apps > Manage Apps.
  2. Tap on the Google Play Store app.
  3. Choose Clear Data > Clear All Data to erase cached data. Choose Clear Data > Clear All Data to erase cached data.
  4. Return to Manage Apps and use the menu to Show All Apps.
  5. Select the Google Play Services app.
  6. Tap Clear Data > Manage Space > Clear All Data to wipe this app as well. Tap Clear Data > Manage Space > Clear All Data to wipe this app as well.
  7. Reboot your Xiaomi device and check if “Device not Certified” has been resolved.

Clearing data forces these apps to re-register your device with Google Play services from scratch. This often fixes certification inconsistencies that cause the error.

Solution 2: Reset Play Services Framework

If clearing app data doesn’t work, you can reset the entire Play services framework with ADB commands:

  1. Enable USB debugging in Developer options on your Xiaomi device.
  2. Connect your phone to a computer with ADB tools installed.
  3. Open a command prompt/terminal window and enter: adb shell pm clear
  4. Then reboot your device and test if certification works correctly.

This resets all Play services data and permissions and essentially factory resets its connection to your device. Combined with a reboot, it often resolves “Device not Certified” errors.
