[Mate 8 General] franzyroy:
Not a problem if you follow the next tuto correctly

Download this TWRP -3.0.2 for Nougat

Open it and extract twrp.img file

Rename it as twrpmate8mm.img

Goes to the SRKtools folder

Goes to the recovery folder

Goes to the mate8 folder

Goes to the emui41 folder

Open mate8.zip file with winrar or other extractor

Inside, you've 2 files,stockrecoverymate8mm.img and twrpmate8mm.img, delete twrpmate8mm.img file in the zip and confirm

Drag and drop your renamed file (twrpmate8mm.img) in the opened zip, confirm

Now, you launch SRKtools app

In the menu, choose 3 (Install recovery 6.0) and enter

Choose 2 (Huawei Mate 8) and enter

Choose 3 (Install Mate 8 TWRP for Marshmallow (EMUI 4.1) and enter

Type y and enter

Type f and enter

Wait the end of installation

The phone will reboot to this recovery and you will see that is good recovery

Don't worry for the step 14 where it's written "EMUI 4.1", like you change the file, it will be really the TWRP for Nougat!

It's as this tuto:

Download SuperSU-v2.79-201612051815-EMUI5.0.zip (there)

Download SRKtools here

Extract SRKtools folder

Goes to supersumm folder

Goes to "1" folder

Rename "SuperSU-v2.79-201612051815-EMUI5.0.zip" as "supersu.zip"

Replace supersu zip (in "1" folder) by the renamed file

Launch SRKtools app

Choose 4 (Root) and enter

Choose 2 (Huawei Mate 8, P9, P9 plus) and enter

Type y and enter

Wait the end of installation

It should Reboot

It's same, like you will change the file, it will make the good installation.

The TWRP tuto works for me, I made it several times. The supersu tuto, I'm not sure because I didn't test it, but I think that yes. However, it shouldn't create some issue, even if it doesn't work. I have to test it this week end. I don't test it in the week because I need my phone for the week.

For the supersu tuto, the only reason which can do that doesn't work, it's when you go to the recovery and choose install, if you see 0 MB to the top. But not sure of that.

To install the TWRP, you have a method more easy, but you have to download that: tools_r25.2.3-windows.zip. Like I say, it's more easy but to install it, you have to know how make.

When it's installed

Download this TWRP -3.0.2 for Nougat

Open it and extract twrp.img file on C:\

Launch cmd in administrator mode from Execut in the start menu of Windows

Make cd\ and enter

Make: cd (PATH-TO)\platform-tools - for me, it's : cd Android studio\platform-tools

Plug your phone with Debug mode activated

A windows ask you to authorize this mode on your phone, push OK

Make: adb devices - if it's ok, it's written

Make: adb reboot bootloader - to reboot in fastboot mode

Make: fastboot flash recovery (PATH-TO)\recovery name.img - in this case, it's: fastboot flash recovery C:\twrp.img

When it's finished, reboot like that: fastboot reboot

When you phone has rebooted, restart your phone in the recovery to check it, like that:

Launch cmd in administrator mode from Execut in the start menu of Windows

Make cd\ and enter

Make: cd (PATH-TO)\platform-tools

Plug your phone with Debug mode activated

A windows ask you to authorize this mode on your phone, push OK

Make: adb devices

Make: adb reboot recovery

Your phone reboot in the TWRP recovery

Enjoy
