Huawei's recent fleet of devices is very interesting thanks to a high value and specs for money ratio. The one thing the company does though that we don't really like in our own niche of Android lovers is its Emotion UI and all the weird choices of design and features that it bundles in it. That can all be solved with a custom ROM and the first step to those ROMs is through installing a custom recovery such as TWRP.
The TWRP team is celebrating July 4 by giving your Huawei device its own independence, that is if it's one of these 8 models. The list includes the new Huawei P9 and P9 Plus and Honor 5C, the relatively new Mate 8, the old Honor 4X, 6, and 6 Plus, and the Mediapad M2 8.0 tablet.
Here are the respective links to their TWRP pages containing download links and installation instructions, but be careful to read and understand what you're doing before you venture into unknown territory:
