Salve ho inviato una email a che mi risposto.
Sapreste aiutarmi perché non ci ho capito niente.
Sono registrato su portal - EMUI ma non ho capito i primi 3 punti oltre che tutto il resto.
Grazie a tutti x l'aiuto.

Hello Dear user:
Huawei Customer is pleasure to be at your service.

If you want to unlock your phone, you should meet these conditions as follow:
1、Please register your own Huawei ID on your phone other than any other third party.
2、Log in your Huawei ID for continuously 14 days on your phone which you need to unlock.
3、Each Huawei ID should not apply for the unlock code more than twice within six months.

You can log in portal - EMUI ask for unlock code When you enter the web page, please click 'Download' button, choose the 'Unlock Bootloader' to log in your Huawei ID, other than any other third party ID, then follow operations as the web page advices.
If you can not log in, please send the screenshoots of the erro message shows on the screen to us and we will help you to check your problems.

We also need you to know that once your phone is rooted, it can be out of the best working state and part of functions may not be able to work normally. In additon, the system is vulnerable to be invaded by viruses once your phone is permitted to unlock. What's more, for the lacking of fully tested, the third party software will not be compatible with your phone. Unlocking will bring unexpected negative impacts and if the device is not normal, and can not be restored, Huawei after-sales service office will not provide warranty service for your rooted phone, and you may bear the cost. So we strongly advice you to think it twice.

If you have any other problem, please send your feedback to us. We will always be at your service to help you to solve your problems. Thank you for your supporting to Huawei and you can add Huawei official Wechat ID: Huawei 400 to learn more.

Hard service 100+, out of service is just the basis, the excess satisfaction is our eternal pursuit!
