Note for devices with high/specific firmware versions:
In order to Remove Huawei/Honor ID on
2.0.0.230 version or higher, perform following operations:
- Read phone’s firmware (backup)
- Downgrade phone’s firmware version
- Run Remove Huawei ID operation
For high firmware versions: If master reset is performed manually or automatically after returning to high firmware version, the device will be ID-locked again. Don't flash the phone with the SD_Update files to return to the high version. You can safely return to high version with the OTA-updates.
