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.

Take Into Account:
Team Win often release several TWRP Recovery files for a particular device. They always recommend installing the latest version of TWRP available to avoid compatibility issues. If you have updated the firmware on the device recently and the most recent version of TWRP is not working, then try downgrading the firmware and trying again.
Some custom ROMs that are newer might not be compatible with older versions of TWRP Recovery. You can fix that issue by updating to the latest version of TWRP also.
You can visit the official Team Win Recovery Project home page and scroll down the list to find your device to get the most recent version if the version available in this guide is not working for your device.
