Editor's Note:#

Because if you want to use "Google Play Store" normally in the future, you must also "access the Internet with scientific methods" (if you don't understand this term, please search it on Baidu), so if you don't understand what scientific methods are, please make sure to acquire this skill first before proceeding. Since accessing the Internet with scientific methods is a completely different topic, this article does not provide technical support for accessing the Internet with scientific methods, so please solve it on your own first.

The method of installing GMS on HarmonyOS 3.0 is from the "Cream Home" blog.


This method is somewhat complicated, and the subsequent operations require accessing the Internet with scientific methods. Therefore, I personally recommend accessing the Internet with scientific methods throughout the installation process, and be sure to follow the video tutorial provided by the blogger "Cream". The URL of the video tutorial is as follows:


I encountered two problems while following the video tutorial to install GMS, and I would like to share them here in the hope of helping those who need it:

  1. At 3:40 in the video, it is required to uninstall the "Backup" component that comes with HarmonyOS. If your "Backup" is the latest version (version number is greater than or equal to:, you do not need to perform this uninstallation step, just skip it and proceed to the next step. If not, please perform the upgrade operation. Similarly, at 6:20 in the video, because "Backup" was not uninstalled earlier, this installation step is not needed, so skip it.

  2. If you encounter the "DF-DFERH-01" error when you reach 15:30 in the operation and the "Play Store" prompts this error, please note that this step requires enabling "Global Mode" when accessing the Internet with scientific methods, or adding custom rules in the scientific methods tool, selecting "Domain and all its subdomains", and filling in This can solve the "DF-DFERH-01" error (the principle is explained in If it still doesn't work, please also set the region of your phone to overseas (such as Hong Kong, China, the method is explained in After configuring the above two points, repeat the operations starting from 14:08 and continue, success is within reach.

I have personally tested this solution and successfully installed GMS on a Huawei phone with HarmonyOS 3.0. The successful model is "Huawei Nova 7 5G". I wish all the buddies a pleasant installation.


  1. After installing according to the tutorial provided by "Cream", do not enable "App Cloning" and "Private Space", otherwise it will report "This device has not obtained Play Protect certification" and cause the phone to not function properly.

  2. If any step is performed incorrectly (including opening App Cloning or Private Space after installation), the problem can be solved by starting over from the beginning. Don't panic.

  3. After reinstalling, a new GSF code will be obtained, so the step of registering the GSF code cannot be omitted after reinstalling.
