First, we need to check whether our mobile phone is on the upgrade list. Only in this batch of upgrade list can the beta version of HarmonyOS System 3.0 be upgraded. Open "My Huawei" app, click "Upgrade early adopters", and then click "View Now" button on the right side of "HarmonyOS3 early adopters" to see the upgrade list.
If your mobile phone is on the upgrade list, you can upgrade it. But before the upgrade, we need to upgrade the HarmonyOS system 2.0 of the mobile phone to the baseline version (the latest version of HarmonyOS system 2.0 of your mobile phone model). Open my Huawei app and click the service button to enter the service interface (as shown below).
