Problem Bootlocker code Huawei

[RVAngelus]

Hello, I'm having trouble solving a problem... I have an old but still functioning Huawei P30. I created an account, purchased 4 credits, and downloaded the software. I start the software, connect the account, connect the phone in manufacture mode, and click on "Read Phone Info," and everything is fine. But as soon as I click on "Read Bootloader Code," it says "Failed, Phone Disconnected." I don't know how to solve it.

It is very unlikely that you will be able to service it via manufacture mode unless your phone runs android 7 or lower, anything higher for your phone will require testpoints. https://hcu-client.com/category/tutorials/ Also only a direct bootloader unlock available for your phone if it runs Kirin980 cpu https://hcu-client.com/supported-models.php

in fact it has the latest version... So waste of money?

Without downgrading it to Android 9, yes.
