Again, please read OP post #3, sections:

"3) How to uninstall Magisk"

"4) How to disable Magisk if you get a Bootloop because of an incompatible Magisk module"

However, if you really want to stay ready for OTA, then go to post #2 and flash the network patch once again, taking (Single SIM L09 or Dual SIM L29, depending on your phone)

NetworkPatch-for-"NonRoot_SINGLE-SIM_VIE-L09.zip"

or

"NetworkPatch-for-NonRoot_DUAL-SIM_VIE-L29.zip"

exactly as described in the post #2, section

"Installing the Patch"

Can you check if Settings / Smart Assistance / Smart cover is On, pointing to the Window case model
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
The reason why you use Root was primarily because of the Playstore certification.... Playstore will stay certified, also, when you Unroot.

Please note, what I answer to [MENTION=2107290]meshoo00oo[/MENTION] It basically applies to OTA (always, even on Android 6 and 7)

1) Most importantly, EMUI-Stock-Recovery must be installed for OTA. OTA does not work with TWRP (except a small patch like Patch01). On Oreo, the place on the phone is: recovery_ramdisk - where either EMUI-Stock-Recovery or TWRP is installed.

If you have TWRP installed, you must change it to EMUI-Stock-Recovery → Look here, Point 3): https://xdaforums.com/showpost.php?p=77650688&postcount=5

But if you have already EMUI-Stock-Recovery, everything is okay.

2) I would uninstall Magisk completely. How to uninstall Magisk completely → look here, Point 3): https://xdaforums.com/showpost.php?p=77650679&postcount=3

OTA does a check before it is applied. And when it discovers root, it usually fails. However, if a firmware update is installed, a new Boot Sector is also written = ramdisk.img

In this case I will upload a new Magisk patched ramdisk.img for the new firmware. The root tutorial remains the same, it just needs to be used for the new firmware, the new patched ramdisk.img. (If you want to root again after the OTA)

BTW: Did you try the zip for FaceUnlock /VoLTE ?
[Huawei P9 Plus Guides, News, & Discussion] Fil76:
Thanks again [MENTION=6870018]Tecalote[/MENTION] so we don't need to reinstall network patch as zgfg said ?
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
[MENTION=7786725]zgfg[/MENTION] Sorry, my post and yours have "overlapped"

No, there is no need to reinstall the network patch! Everything is working now, Playstore is certified (the reason, why you did Root) - just uninstall Magisk from Magisk Manager and make sure, you have EMUI-Stock-Recovery. Thats all! :fingers-crossed:

As long as you have not made "Night Update" or "Automatic System Updates" in the settings, you can also do the Unroot before you allow the OTA.

There is only one thing - if the OTA (new complete Firmware) would delete the network settings, then you must reinstall the network patch, but not now. And I guess, OTA will not do that.
[Huawei P9 Plus Guides, News, & Discussion] jvelasco:
Thanks for your hard work... :)

Maybe some future version (module) for Magisk?
[Huawei P9 Plus Guides, News, & Discussion] Fil76:
You are great Tecalote, thanks again
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
I understand what you mean. I wrote a Guide "How to do" for you. Teamviewer and Telegram is an idea, but my time is very limited. I am not at home from 6:30 in the morning until 8:00 in the evening, but have a lot of other projects.... You understand that I'm not an employee of xda who is paid here to provide telephone support?

Is there no friend near you who has experience and might be able to help you?

→ There is one thing that I could do. I could make a zip file for you, which you would have to flash with TWRP. This zip file would uninstall all the Chinese apps and install Playstore and Google Keyboard.

For this you would have to unlock the bootloader with your code (which will wipe your internal storage and apps and data) and then flashing TWRP (to be able to flash the zip file)....

[MENTION=9478866]bisder[/MENTION] Have you tested the steps from here: https://xdaforums.com/showpost.php?p=77760369&postcount=100

Thank you for your reply. I checked the settings and it is activated. I try to disable and reactive case with and without window, I disable faceunlock and Volte, I have reboot the Phone many times , wipe cache and dalvik, same problem
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
Did you also delete the Face Picture in FaceUnlock settings, before disabling? If it does not work, I can make a zip for Uninstall FaceUnlock - no problem. But I can not guarantee that this will solve it.

If I'm to do the uninstall zip, then I'll do it tomorrow at the same time as today, but right now I do not have time for it. Just tell me, if you need it
[Huawei P9 Plus Guides, News, & Discussion] meshoo00oo:
Yes and the faceunlock & Volte are working great:good:
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
I pointed you how to unroot Magisk and then I didn't say that reflashing Network patch is neccessary - I suggested it for the clean OTA ready 'reatart'

And yes, it would trigger Factory reset (reformatting Data and Internal mem) but that is not so tragic - you have very useful stock Backup app, you can backup all Apps and their data, Contacts, Call logs, Messages..., even Settings (yes, you can because reinstalling same b528) at the beginning, and at the end just restore them all.

Of course, must select SD card for backup (not Internal mem, because Factory reset wipes Internal mem)

---------- Post added at 12:51 AM ---------- Previous post was at 12:36 AM ----------

Just a note, be aware that current TWRP for Oreo cannot wipe Dalwik cache (it has that option, it does not report an error but doesn't wipe Dalwik).

With TWRP you can only wipe Cache (not Dalwik Cache).

Reason: This TWRP does not support encryption for the Internal mem and Data (OP post #2), hence cannot wipe /data/dalwik-cache

(also, you cannot backup full Nandroid because you can't backup Data partition.

And you cannot install anything from Internal mem, but only from SD card or OTG)

To wipe Dalwik you must have root, then simply use MiXPlorer, navigate to Root, data, and delete dalwik-cache folder, and reboot

(If you also want to wipe Cache, reboot to TWRP, wipe Cache and then reboot back to System.

For easier rebooting, use Reboot app where you can choose would you want to reboot to System, Recovery or Fastboot)
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
That would be for a complete pure "new beginning" - but in the case of [MENTION=6288261]Fil76[/MENTION] not necessary.

Basically not necessary for OTA. The only important thing is that EMUI-Stock-Recovery (instead of TWRP) is installed and a Unroot from Magisk Manager is done.

That's enough to run the OTA. If it does not work, you can still select "Download latest full package" in the 3dot setup menu of Systemupdate.

I have tested it by myself with Huawei Mate 9 Oreo 8.0 (MHA-L29) and Honor View 10 Oreo 8.1 (BKL-L04).

I had TWRP installed and Magisk Root. I just reinstalled EMUI-Stock-Recovery and uninstalled Magisk Root. OTA was successfully. Just in one situation it did not work, then I opened Settings /Systemupdate / 3dot menu: Download latest full package - and there was not any problem to apply the OTA (was also successful).

I know what I am talking about. You can believe me. :)

→ But making a Backkup with Huawei Backup is always a good idea!

Hello, I'm very happy, my phone has 2 sim services. Arrived at 2:00 am at home, I am very happy and would like to give you the sincere and deepest thanks.

I did, in the process I got an error and the system just booted into Rom test, I was very worried, but then I checked again that I coppy missing UPdate.zip file. And I copied it and made it back to step 7. Now everything is great.

Thank you very much!

You ask me if after doing this, the system automatically update to Android 8.0 or not?
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
I'm also glad that everything worked great, although you did not think you could do it at first :good:

But something you have to live with now is: there is no Oreo for the international models and it will not come. That's why I've created a way for other users to rewrite their international model into a Chinese to enjoy Oreo.

I give you the hint here "Note: Oreo is only for Chinese models....": https://xdaforums.com/showpost.php?p=77764071&postcount=102
[Huawei P9 Plus Guides, News, & Discussion] yueyong:
The link you sent me in this comment is tips's rebrand for my phone? So we are not the way to upgrade to Oreo?
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
Maybe I missunderstood you - or you missunderstood me.... ;)

Your first post was: "I just bought Huawei P9 plus inland China, it is running Android 8.0. I have the bootloader unlock code. I hope you help downrage about 7.0 or help me Upgrade to the Global version. Sincerely thank! My phone: VIE-AL10 8.0.0.528(C00patch01)"

→ you were already on Oreo

I asked you: "Why you want to change your current version, what's would be the advantage for you? For me isn't clear, why you want to do that at all. What's better on Android 7 /Model L29? I asked you some Posts before, but you didn't answer directly. You said "I want to downgrade and change Firmware to the international version" - but you didn't say: Why...? "

You answered: " My goal is to upgrade to the Global version, but through some of them they say they have to downgrade to Android 7.0 so i ask you downrgade 7.0. And you answered me the need to downgrade to 7.0 if you want to go to the Global version . This issue has been resolved

My purpose is to transfer the international version. The Chinese version of my Huawei P9 + made me very difficult to use because there are still many Chinese entries. Hope you understand what I say. Thank you"

I wrote a Guide here for you, how to downgrade from OREO to Android 7 and rebrand to VIE-L29 → to get rid of the Chinese "entries" - In this Guide I wrote at first, please note, Oreo is only available for Chinese models (VIE-AL10): https://xdaforums.com/showpost.php?p=77764071&postcount=102

→ there is no "Global version" with Oreo and it will never be.

→ there is no "International version" with Oreo and it will never be.

If you would rebrand back to VIE-AL10 and then upgrade to Oreo → you would have the same phone as before.

I understood that you would like to downgrade from Android 8 to Android 7 and switch to an international model to get rid of the Chinese applications.

Most of us has European P9 Plus and we rebrand to China P9 Plus → to get Oreo → because Oreo does not exist for European P9 Plus, and it will never be. Thats why I did not understand what you want and asked you twice.

And for the case, that you would like to stay on Oreo (VIE-AL10) I offered you here: "There is another thing that I could do. I could make a zip file for you, which you would have to flash with TWRP. This zip file would uninstall all the Chinese apps and install Playstore and Google Keyboard (→ on your VIE-AL10 OREO)For this you would have to unlock the bootloader with your code (which will wipe your internal storage and apps and data) and then flashing TWRP (to be able to flash the zip file)...." : https://xdaforums.com/showpost.php?p=77772719&postcount=121

Sorry, but you thought maybe, you must change to another "Oreo" Version - but I must tell you, it does not exist and it never will....

Oreo is only available in China and not in "Oversea" for P9 Plus ;)

In Post #2 (at the end) is a Link for a zip file with Apps. Extract it and install HwCloudDrive_EU.

Then accept some license requests and you should be able to synchronize with Huawei ID (5 GB with calendar etc..)

[Huawei P9 Plus Guides, News, & Discussion] yueyong:

Few days ago, before you started rebranding to Global Nougat, you were exactly on that Chinese Oreo (and [MENTION=6870018]Tecalote[/MENTION] asked you if you just wanted to get rid of Chinese bloatware instead of rebranding to Nougat) - so now you want to go back?

Of course, you can do it...
[Huawei P9 Plus Guides, News, & Discussion] meshoo00oo:
Just another thing to do is to install Google calendar from Google play Store to let the Google account start to sync calendar also to let the Google account appear on the Huawei calendar stock app as shown in the attached photo

[Huawei P9 Plus Guides, News, & Discussion] zgfg:
Explained already several times, either

A)Chinese Nougat or Oreo

B) Global Nougat

No way for Global Oreo (unless you develop yourself)

Complain to Huawei :)
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
There is no Oreo for the Global version !! If you need Oreo, why you did downgrade and rebrand??

This discussion must now be ended. Either you stay on the current version, which also gets updates via OTA - or you go back to your original version with Oreo.

To go back to VIE-AL10 (your original model) use HWOTA7 Tool, Guide in Post #2: https://xdaforums.com/showpost.php?p=77650678&postcount=2

A) Download the two Firmwares (which are linked in Post 2) - remember to rename two zip files of each Firmware Version

B) start with Step by Step section and do the steps from 0 to 18 inclusive (nothing else more) - then you are back on your previous System (from which you started to downgrade and rebrand).

There is nothing else we can do for you - because I am not Huawei, and I am not responsible for the fact that Huawei does not provide Android 8 Oreo for Global / International versions, but only for Chinese devices !! :cyclops:

Hi all,

I came from L29 device to AL10.

However, I found out that my remote apps can not detect the IR blaster.

Initially I tried to download other IR blaster remote software (after failed to use my Smart Controller app) but they all said my device don't have the IR blaster.

Is this happening to your devices also?

I am wondering if I have uninstalled certain Huawei original app (can't remember which one) to cause this to happen. My Huawei's Smart Controller app is still there but it just wouldn't start (it just closes by itself).

Are you facing the situation your IR blaster not working too?

Or do you have any suggestion to solve this issue?
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
If you read some posts back, it's already reported and known - I will look how to solve.

Soon I find the solution I will post here.

I am just wondering if this is cause of the Faceunlock zip or if this issue was also before?

I did not test.

However, I think it is fix able
[Huawei P9 Plus Guides, News, & Discussion] prismfire:
I see. Thanks for the info. I only searched "remote" and "ir blaster" and didn't get any results so i assume there wasn't anyone facing it. Sorry about that.
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
No Problem :)

Did you flash FaceUnlock/VoLTE zip? If not, I would know if it has to do this mod.
[Huawei P9 Plus Guides, News, & Discussion] prismfire:
I can't remember exactly if I've tried the Smart Controller before I installed the FaceUnlock/VoLTE patch. I think I've tried opening it and it works before I uninstalled other not-needed-Huawei-apps. And also before I installed the mentioned patch. Will try to revert back to Nougat first and try again. May take some time.

Edit: Yep. Tested. Reverted to Nougat, then upgrade to Oreo. Did not do anything else aside from connecting to Wifi. Tested Smart Controller -> works (as in the app turns on and I can navigate on it well). Flash the FaceUnlock/VoLTE patch. Tested Smart Controller -> doesn't work (app wouldn't start properly).

Thank you just a question about your guide #5....at point

fastboot flash recovery_ramdisk VIE-b528-RECOVERY_RAMDIS.img

cause i have modified ramdisk for root ...may i do to preserve root

fastboot flash ramdisk VIE-b528v17.1-encrypt-dmverity-ramdisk.img

or i must unroot before ?
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
Difference between recovery_ramdisk and ramdisk !

Please do not confuse !!

recovery_ramdisk = RECOVERY (can be EMUI Stock Recovery = VIE-b528-RECOVERY_RAMDIS.img - or: TWRP P9-VIE_EVA-8.0.0-TWRP-v4.img → dependend, which one you install)

ramdisk.img = BOOT (can be Magisk patched ramdisk.img = VIE-b528v17.1-encrypt-dmverity-ramdisk.img - or: original (non patched) ramdisk.img = VIE-b528-RAMDISK.img → dependend, if you use Root or not!)

No need to Unroot! But for enabled OTA you should have EMUI-Stock-Recovery instead of TWRP. Recovery has nothing to do with Boot :)

BTW: If you would flash recovery_ramdisk to: ramdisk (=wrong) - your Phone would not boot!

recovery_ramdisk must be flashed to: recovery_ramdisk

and ramdisk must be flashed to ramdisk
