As a start, this phone is great and I feel that it doesn’t need to be unlocked and rooted for a stable and long lasting daily use. However, unlock and root is almost a religion if you use Android phones
As a piece of info, big thanks to @raimondomartire, there is a thread for unlock, flash TWRP and root in the Mate 9 forum https://forum.xda-developers.com/mate-9/development/recovery-huawei-mate-9-pro-unofficial-t3546976, which is however according to my experience not totally applicable for the M9Pro anymore. There are also several other threads on the Mate 9 forum. Many things can be shared between both phones, but not always. Be careful about what you are doing!
-----
General info and attentions:
- My phone is M9Pro LON-AL00 (All net version from Chinese Mainland); LON-L29 (International version) should also work.
- This thread applies for build LON-AL00C00B213. Can be also applicable for similar builds, but I couldn’t test. Please report.
- None of the current builds of TWRP (up to 3.1.0) can decrypt data partition by default, which means you could only format the data partition in TWRP in order to access it in recovery (for backup to and install from internal storage etc.). But after formatting, you have to flash Huawei’s special stock data back to data partition (/data/hw_init), otherwise several functions of Huawei ROM won’t work. Refer to this (https://forum.xda-developers.com/showpost.php?p=71302827&postcount=627) or this (https://forum.xda-developers.com/showpost.php?p=72497328&postcount=204). Thanks to @gm007 and @ante0
- There are several root methods which handles encrypted or decrypted data partition. I didn’t format the data partition, i.e. data is still encrypted. If you want to format the data partition, please refer to this thread: https://forum.xda-developers.com/mate-9/how-to/guide-how-to-root-mate-9-decrypt-data-t3569986. Thanks to @eddmecha
- If you need stock ROM, refer to useful links below. Use Huawei Update Extractor to extract the individual partitions from the ROM: https://forum.xda-developers.com/showthread.php?t=2433454
-----
Unlock bootloader:
There is enough info in the internet about unlocking M9Pro’s bootloader. Just a few points to mention:
- Generally, you can follow the steps in @raimondomartire thread (https://forum.xda-developers.com/mate-9/development/recovery-huawei-mate-9-pro-unofficial-t3546976). But unlike he describes in his thread, there is no OEM Unlock options in the developer options anymore. Just use ADB to unlock.
- FRP unlock is not required!
- Huawei enables now a 14-day limitation, where you can officially get the bootloader unlock code 14 days after you first activate your Huawei ID on your phone and have logged in using your Huawei ID 14 CONSECUTIVE days.
- To go around this limitation, you can use dc-unlocker to get the bootloader code immediately. Google yourself
-----
Flash TWRP:
- Still, you can follow the steps in @raimondomartire thread (https://forum.xda-developers.com/mate-9/development/recovery-huawei-mate-9-pro-unofficial-t3546976).
- The image from this thread is 3.0.3, which has some bugs built in, especially when flashing SuperSU.
- You could use TWRP 3.1.0-1 from https://forum.xda-developers.com/mate-9/development/recovery-unofficial-twrp-huawei-mate-9-t3515617, but this one seems to have problem to be recognized as ADB device in recovery.
- There is a version 3.0.2 for Mate 9, which seems to have problem mounting USB-OTG.
- If your data partition is encrypted, you can only use ADB sideload or USB-OTG to install anything.
- If you want to do data wipe in TWRP, you have to flash Huawei’s special stock data back to data partition. See above general info and attentions.

Root:
Firstly, thanks to @ante0 for explaining different flags in the root methods: https://forum.xda-developers.com/showpost.php?p=72504501&postcount=210. Some more discussions between us are also around this post.
I also tried several other root tools on the market (mobilego, vroot, YoRoot, OneClickRoot, iRoot etc.), NONE of them works.
As mentioned, there are different root methods around for unlocking M9Pro, depending on if you want to format your data partition. For me, I didn’t format, and SuperSU works for me. And the mate_9_pro_root.zip from @raimondomartire thread didn’t work for me.
I followed the steps below:
1. Get TWRP 3.1.0-1 (https://forum.xda-developers.com/mate-9/development/recovery-unofficial-twrp-huawei-mate-9-t3515617)
2. Disable fingerprint ID (I think it’s probably optional, but have read somewhere that fingerprint stops working after flashing root).
3. Flash stock boot image for B213D (in download section). I think it’s optional too, but if you have tried other methods before, you can do this step to make sure your boot is stock and clean
4. Flash TWRP 3.1.0-1
5. Flash SuperSU-v2.79-MATE9-init.d_support_no_decrypt-signed.zip (in download section) via USB-OTG (in TWRP the device is not recognized as an ADB device, hence no “ADB sideload”). Thanks to @ante0 for building this zip!
6. Reboot – phone will reboot itself twice and SuperSU.apk will be installed automatically
7. You could flash back to 3.0.3, if you want the ADB sideload function.

Just some clarification: (eventhough you wrote it's for AL00C00B213, which I missed xD)
Flashing stock boot is only needed if you're already rooted.
Boot image B213D is only for AL00C00. If you have a different model/build, use the boot image for that specific build:
Download your stock firmware from hwmt.ru and Huawei Update Extractor. Extract update.app from your firmware zip.
Open update.app in Huawei Update Extractor. Rightclick on BOOT and click on Extract selected.
Flash the extracted boot.img using fastboot in download mode (fastboot flash boot boot.img).
OEM Unlocking is required to be enabled. It's just not there in the chinese version (AL00). So check if it's there first and enable if it is.

Hi guys. Not sure if this is the right place to ask but how do I get rid of that annoying "your device is unlocked and can't be trusted....etc " msg?

hi guys. You may or may not find this interesting. I certainly did. I'll post this in the mate 9 pro forum as well but i just thought i could get some ideas from as many of guys as possible seeying that theres a lot more posts here for mate 9 in general.
I have chinese version mate 9 pro that has been rebranded from AL00 to LON Spcseas and rooted. Build number b228. Anyway i recently saw in FF the new b229 so i downloaded all three files which had longer file names than usuall by the way. In twrp, the only file that was visable was the update.zip. So i renamed the hw and public zip files to what they would usually be named. Wiped data, and flashed all three files. Then reflashed supersu.
This is the interesting bit ( i think ). My imei numbers have changed, before flashing, the first imei number ended in 7 - now it ends with 4, the second imei number ended in 9 and now it ends with 7. Also, i now have a MEID number visable which was not there before and a section called android security patch level. Oddly enough im not getting any issues out of play store, im on play store right now and not a single problem regarding authentication. The build number is the same as well. As far as functionality goes, everything seems to be tip top, in fact everything seems to be working better, even unofficial exposed is working well. Only one thing isn't working properly. In phone manager there was a feature in the battery section that darkens the interface for everything to save power and prolong battery. That doesn't seem to be working anymore. In App - Permissions, the permissions is greyed out and it says no permissions requested.. Any thoughts or explenations guys??

Trying to flash another orginal stock rom
I bought a Mate 9 Pro, China Version (LON-AL00C00) want to install Mate 9 Pro, Asia Version (LON-L29C636) software on it. All explanations about Mate 9 Pro is for models which have SD Card. My Mate 9 Pro with dual sims and not containing a SD Card enrty.
I succesfully unlocked the bootloader, installed TWRP but couldn't flash LON-L29C636 stock software. Because TWRP don't see update.zip file. Not only update.zip, any files I downloaded or copied before. When I put a OGT TWRP suddenly exits and phone restarts.:crying:
As you see I can't flash a zip file and ofcourse superuser zip file to root as well. I'm stuck in this triangle. Please give me a hand guys.

I can't root my phone. Because I can't view and locate any file of my phone. When I plug a ogt cable twrp exits and phone restarts. 6GB-128GB Dual Sim version

I unlocked bootloader but couldn't root. Anyway I wanted to rebrand my phone to Asia version. Now I'm done but not successful because there is no Google,frp locked, and version is test one.
I can't install twrp because frp lock don't allow it. Also twrp can't read 128 GB internal memory, so I needed to install from pc.
Is there anyway to resolve and install stock Oreo version to my Mate 9 Pro or do you suggest me to resolve it via paid services?

I've installed Oreo to Mate 9 Pro. If you have 128GB edition don't try to install anything from internal storage. That's it.

Rebranding is easy with HWOTA system if you will keep your phone EMUI 5.0 Nougat. And there is no risk if you make everything clearly.

Yes you can always flash stock ROM as factory out, if you are not in Oreo.
And you can root it. It's your own protection to have a backup. I suggest you have, anyway it's up to you. You can loose all your data after root.

Hi, yersterday I used TWRP trying to install a newer firmware and I wiped system partition and now it does not boot because it doesn't have an OS. I was on EMUI 8 (636) trying to update the firmware.
Is there any way to flash a firmware via TWRP or Fastboot on EMUI 8 (i know partition names change on Oreo).
Thanks!
