[Huawei Mate 9 Questions & Answers] prestonmcafee:
I'm quite lost about how to install Magisk and a camera module

At the risk of asking too much, I have another request. I'm looking at how to install the stock camera on my Mate 9 with the AOSP, and here is my pathetic understanding of the steps.

First, I looked at your (Wirmpolter) instructions:

1. Install latest Magisk Manager from the Official Thread: https://xdaforums.com/app...mless-t3473445

Follow the instructions of "Install Via Magisk Manager" in the main thread, but instead of providing the boot image (which these devices do NOT have), provide the stock ramdisk.img extracted from your Update.app using Huawei Update Extractor.

2. If you are using Mate 9 with model MHA-L29636 running on firmware ending in B362, you can download the stock ramdisk.img I extracted from official OTAs in the attachments

If you have stock ramdisk images for other devices, please share them and I'll add them to the OP.

3. Pull the patched image with adb pull /sdcard/MagiskManager/patched_boot.img, and flash the patched ramdisk via fastboot:

fastboot flash ramdisk patched_boot.img

Reboot and you shall have a properly rooted device passing SafetyNet, start playing with some Magisk modules!

Here are some questions:

1. Huawei update extractor

I probably need help using this. The item I need extracted is the update.app, but where do I get the update.app that I extract from? And I'm extracting ramdisk.img?

2. download file for my phone that will be the source of the update.app in #1 (MHA-L29 8.0.0.366(C567)) from FunkyHuawei? Firmware finder? or from the phone itself? (see, I'm pretty lost)

3. install magisk manager (from https://xdaforums.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445):

This method does not need root, and also does not require a custom recovery.

However, you MUST have a stock boot image dump beforehand, and you also have to be able to flash the patched boot image, either through fastboot/download mode or ODIN

Install the latest Magisk Manager -- this is an android app? Do I sideload it?

If you're planning to flash the patched boot image through ODIN, go to Settings > Update Settings > Patched Boot Output Format, and select .img.tar. For normal users leave it as the default .img

Press Install > Install > Patch Boot Image File, and select your stock boot image file

Magisk Manager will now patch your boot image, and store it in [Internal Storage]/MagiskManager/patched_boot.img[.tar]

Copy the patched boot image to your PC. If you can't find it via MTP, you can pull the file with ADB:

adb pull /sdcard/MagiskManager/patched_boot.img[.tar]

Flash the patched boot image to your device and reboot. Here is the command if using fastboot:

fastboot flash boot /path/to/patched_boot.img

Magiskmanager is an android app. How do I install on my phone? I was expecting this to be a windows app that would install magisk on my phone, so was thrown when it was an .apk.

Finally, the camera image is here:

It isn't clear to me how to flash using Magisk, but perhaps that will be obvious once I have magisk operating.
