After you have unlocked the bootloader on your Huawei P9 Plus, you will probably want to install a custom recovery and root your phone. As you already know, the process of flashing a custom recovery is not that difficult if you just have an unlocked bootloader.

Once you have installed a custom recovery on your phone, you can then use the recovery to flash SuperSU, which will help you gain root on the phone. That way, you will have a custom recovery along with root access on your phone and that is the very thing that you need to be able to play around with the custom Android stuff.

This is what you need to get TWRP Recovery installed on the Huawei P9 Plus smartphone and then get root access to it.
