Are you rooted? Are you using Stock Rom from huawei?
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Mohammed_M.:
No I don't have root I have emui 8 and everything is stock
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Emare212:
Then you can use HiSuite on your PC to create a backup of your data.

So if you are using EMUI 8 your phone is already on stock Oreo?
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] KitsuneUK:
Is the front camera working in the stock huawei camera on RR? if it is might try updating tonight...
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Mohammed_M.:
Yes it is on stock oreo I did a backup of the data but what about the system? Or update.app so I can back to stock again if I wanted to?
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Emare212:
Normal Camera app works well for me with both cameras. I don't have Huawei Stock Camera installed.

---------- Post added at 03:44 PM ---------- Previous post was at 03:25 PM ----------

If you have your data backup already you can easily go to RR and back to Stock if you want with this method.

First you need to unlock your bootloader with the code you will get/got from Huawei. See here.

1. Go to firmware database and find your stock firmware (which you are using atm)

2. Download the FullOTA-MF-PV (click on "update" to download) and unzip it.

3. Download Huawei Update Extractor

4. Open Huawei Update Extractor and go to settings --> Disable both checksum boxes

5. Import your update.app File

6. Mark kernel.img, ramdisk.img and recovery_ramdis.img and rightclick -> Extract Selected

7. Flash them trought fastboot

fastboot flash kernel kernel.img
fastboot flash ramdisk ramdisk.img
fastboot flash recovery_ramdisk recovery_ramdis.img

8. Go to Recovery and do a factory reset and cache wipe

9. Flash your RR rom system.img with

fastboot flash system system.img

10. Flash TWRP if you want

fastboot flash recovery_ramdisk twrp.img

Get TWRP here: https://mega.nz/#!pT5lRA7Y!G5DhJdsR-...fHGzN8OOu9aCko or here https://xdaforums.com/mate-9/development/recovery-twrp-3-2-1-0-oreo-t3734967

11. Reboot

12. Optional Root with Magisk 15.4 (see here) --> Simply flash the zip in TWRP and install Magisk Manager App (if you fail in SafetyNet Test flash after Reboot this in TWRP)

13. Update in Magisk Manger App directly to Magisk 16

[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Emare212:
No Problem. For Step 1-7 I dont know, if it's meaningful for you, because you are already on Stock. Maybe [MENTION=6929004]osk4rin[/MENTION], [MENTION=2247733]ante0[/MENTION] or [MENTION=1397125]ajsmsg78[/MENTION] knows it.

Gapps and SU. Try as I might I always end up with all my apps crashing :(

I sorted out "pending" on the Play Store by force stopping it a few times, after that it downloaded whatever I wanted immediately, but I can't open any of the apps :crying:
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] osk4rin:
That is weird,I don't have any issue on Play Store anymore.perform a factory reset or flashed again over your stock EMUI 8.

You could customize your apps as well with the vanilla version.

Did you try updating you Google Play Services? link: http://www.apkmirror.com/apk/google-inc/google-play-services/

I was having that issue and I couldn't log in to google in setup.

What I did:

format data

flashed boot, kernel, system

boot into the os

reboot to twrp, factory reset, gapps

boot into the os

skip through the setup, make sure to press skip so you can come back later

put the newest play services on the sd card/internal storage and go to the "Files" app and flash that new apk

go to settings, at the top there is a banner to "Finish setting up your MHA-L29". Tap this

finish setting up your google account, etc

The quick swipe down of notification panel stops working (Show notification panel by swiping lower half of the screen). When the rom was just flashed, this function worked well. But after downloading and updating apps, this function stopped. Any ideas or solutions?

I have a mate 9 C567, with RR rom V4. Use TWRP and Gapps posted in the first page.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] osk4rin:
Install the Gapps again and do a factory reset.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] huhtan:
Installed the Gapps and did a factory reset via twrp. Rebooted the phone and it is stuck at setup, "Just a sec" page.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] osk4rin:
Works fine with me with any Treble rom. The other thing you can do is go back to EMUI and flash the Rom again following the same steps.

Thanks anyway. I will give it another try later.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] huhtan:

I using resurrection remix as a daily drive, which is really fast and smooth.also, it has a lot of feature.

Ether install addonsu, or magisk, but I recommend you addonsu, because magisk is not stable at all on treble Roms, it messed up with adb usb debugging.

Is not necessary to have magisk to have the P20 camera, just flashed on TWRP. In terms of performance, camera is stable, better than the stock huawei module.

Thanks. Is the picture quality better with the P20 module? I'm not experiencing stability issues.

I have been avoiding TWRP because recovery is straightforward with the stock EMUI recovery, though I haven't needed recovery in a while.

I tried to remix with Lineage.

But both sd card or otg sd error is not installed in ROM.

I tried to install the ROM by using full wipe (data, cache, system).

However, sd error will not be installed.

[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Emare212:
To flash Magisk the first time you need TWRP, because, if I remember correctly, stock recovery can't flash zips.

After flashing Magisk you can go back to stock if you want.

You can always go back to stock Recovery with

fastboot flash recovery_ramdisk recovery_ramdis.img

[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Emare212:

As a matter of fact, I want remix os.

But currently my twrp sd or otg remix os from flash memory will check for external memory errors.

I am frustrated because I can not do this either.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] osk4rin:
You can't flash RR Remix fromTWRP. because is a img. Is not a flashable zip.

You have to flash it from bootloader via fastboot
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] AcaSia0388:
So this is it ??

So this is it ??

rr Remix Do you want to unzip the zip and put the system img in the adb tool and then flash it?

1/4 failure ... I'm sad.

---------- Post added at 08:42 PM ---------- Previous post was at 08:27 PM ----------

I will try again.

What should I flesh out when installing this remix ROM?

Do I have to work on my camera, Google Play (Gaps), etc.?

Does the remix os update automatically update as usual?
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] osk4rin:
Yes, extract the img. From the RR zip file. Then go reboot to bootloader. Press volume up while holding and connect the USB cable to boot in bootloader. Then

Fastboot flash system (img file)

But you have to extract your kernel and ramdisk img files from the UPDATE APP from you stock firmware on huawei extractor. Otherwise you will end on a bootlop
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Emare212:
If you dont know how to extract look at these steps.

You can download Minimal ADB and Fastboot Tool and just type the commands from the steps in there, after you put your Phone in fastboot mode like [MENTION=6929004]osk4rin[/MENTION] described.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] AcaSia0388:
I have already succeeded Thanks!

Remix rr rom img just fleshed out.

Do I need to extract other updates, such as .app?

When installing the ROM, there is no initial progress window and it is directly entered into the desktop.

The device name is Huawei Honorary v10.

Will I have problems with future updates?
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] osk4rin:
You don't need to flash the gapps. They are already included on the Rom.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Emare212:
In this Rom is no "Start Tutorial". So you are fine.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Mohammed_M.:

[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] AcaSia0388:
Is the rom update method img?

How do I change from current Rm rom to Lineage? Is this img fleshing? Or is it compression flesh?
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Emare212:
For me there was also the problem, when listening to music, youtube etc. that the volume was low and the quality bad.

I turned off the App "Audio FX". After that the sound was normal. To turn it off just open the app and turn the switch in the upper right corner to off.

---------- Post added at 11:49 AM ---------- Previous post was at 11:46 AM ----------

So there isn't an update for this rom yet. You can follow it in this channel.

I think OTA updates for this rom are possible and realistic. If I'm wrong correct me please.

I didnt take a look at Lineage, but you can see it if you download the rom on your PC. If it's a system.img or something .img you need to flash it like RR. If it's a .zip you can flash it, following their instructions.

But I think, that there was an limitation in TWRP on Oero, why you can't flash .zip Roms there. But I don't remember really :confused:
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Mohammed_M.:
I did that and the sound quality is very good but I still want the front speaker to work with the original speaker to give a better quality if you understood what I mean. ☺️?
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Emare212:
So you mean that the front speaker is also on when you hear music with the main speaker?

Was this a standard function of your phone? I can't remember :confused: If this is an extra function maybe google it or look in xposed/magisk modules
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Mohammed_M.:
It was a standard function... Not just with music but actually with every thing it was dual speaker working together to give best quality .... But now just one speaker work when watching video or playing music (earpiece no longer work as speaker)
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Emare212:
Okay, now I know what you mean.

But I don't know how to turn it back on. Maybe in Settings somewhere, but I don't think.

Maybe search the official Thread of the Rom for more information about this.

But I think it's because this rom was build for Honor View 10 originally and just runs on our Mate 9 ;)
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Mohammed_M.:
Yes but actually it's not a big deal but if it returns back it will be great and really thank you my friend ? ☺️
