Manually Update Firmware b535 → b537

Firmware VIE-AL10C00B537 (8.0.0.537)​

Required for the Firmware update is installed TWRP https://www.androidfilehost.com/?fid=1322778262903998750

Additonal information to the manual Firmware-Update from b535 (or even from b528) → to b537 → or even to next version in the future:

1) Download current Firmware VIE-AL10C00B537 (8.0.0.537):

http://update.hicloud.com:8180/TDS/data/files/p3/s15/G3133/g1699/v200303/f1/full/update.zip

http://update.hicloud.com:8180/TDS/data/files/p3/s15/G3133/g1699/v200303/f1/full/public/update_data_full_public.zip

http://update.hicloud.com:8180/TDS/data/files/p3/s15/G3133/g1699/v200303/f1/full/VIE-AL10_all_cn/update_full_VIE-AL10_all_cn.zip

2) Let Windows show file extensions (to make sure you have at the end not zip.zip) and rename the last two zip files - (update.zip - do not rename)

update_data_full_public.zip - rename to: update_data_public.zip

update_full_VIE-AL10_all_cn.zip - rename to: update_all_hw.zip

3) Download Firmware-Update.zip file and extract (unzipp) it: https://www.androidfilehost.com/?fid=11410963190603867993

Inside is the folder: HWOTA and contains two files. Do not rename that files.

4) Create a folder on your external SD with the Name HWOTA in the main directory (dont use another name!) - or copy the HWOTA folder from unzipped Firmware-Update.zip instead to your external SD

5) So you have now the folder HWOTA on your external SD (without Subfolders between)

6) The folder HWOTA must contain:

eva_vie_recovery_nocheck.img

ExtSD-FirmwareUpdateScript.zip

update.zip

update_all_hw.zip

update_data_public.zip

7) Now boot to TWRP, cancle Password, allow system modification, go to Install, select storage: Micro SD - and flash ONLY the one zip file with the name: ExtSD-FirmwareUpdateScript.zip

8) The phone will reboot and needs a while to flash automatically the No Check EMUI-Recovery and this needs also a while until the Firmware will be flashed automatically as well as Phone reboots after. Just wait, until it boot up.

→ if you have Root, there is no need to Unroot before and you will loose no installed apps, except probably Playstore (if it was not updated, if it was updated, you will also not loose Playstore and not Keyboard)

→ but you have to flash the Network Patch from #2 - and if Playstore is missing, just install the attached Playstore apk and reboot phone.
[Huawei P9 Plus Guides, News, & Discussion] n20661:
Thanks for the detailed instructions.

If I have no root, can I make above update procedure? will it work - update seemlessly - despite it is not approved b537?

do i have to install at the end the network patch zip? I suppose yes.

thanks a lot.
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
No difference if you have root or not - you can upgrade.

Again you can root b539 if you wish, or not.

Yes, you will need to flash Network patch again, and Face Unlock - if you need the face unlock feature.
[Huawei P9 Plus Guides, News, & Discussion] n20661:
I cannot boot into twrp. When I try it says after a while, installation failed ---> then reboot.

I reboot to b537 but cant install network patch.

what could be wrong...?

help me please
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
To boot to TWRP you must disconnect the USB cable and press Vol+ and Power Button until TWRP is booting up.

If you miss this step TWRP get overwritten.

And you must flash TWRP in Fastboot mode with the right command for Oreo (basically different to the one from Nougat)

Read about in Post #2 (after rebranding section)
[Huawei P9 Plus Guides, News, & Discussion] n20661:
I will try it... then say if it is ok.. or not.

thanks

---------- Post added at 10:12 PM ---------- Previous post was at 09:58 PM ----------

I did it like you said:

"Installing the Patch

→ you need just one Patch (related to your origin model - either with OTA on or off)

21) Copy the downloaded TWRP (from STEP 20) into the folder C:\HWOTA7\tools\Windows - connect P9 Plus with USB to PC - right click on cmd-here-exe (run as administrator) - type: adb reboot bootloader (enter, to restart your P9 Plus into Fastboot mode)

Code:

fastboot flash recovery_ramdisk P9-VIE_EVA-8.0.0-TWRP-v4.img

22) Disconnect the USB cable from P9 Plus and press (with the left hand) VOL+ and Power Button (with the right hand) and keep pressing until the Phone is rebooted into TWRP.

"

but still cant boot into twrp. only rebbot in recovery mode, no TWRP....

does it needs another twrp?

I do not know... only emui logo and black screen wehen pressing vol+ and power....

please help.

How can i do the factory reset with b535 firmware?
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
Settings / System / Reset / Factory Reset

Alternatively, go to dialer and 'dial' a secret code *#*#2846579#*#* to open Project Menu, then choose Factory Reset

Also from EMUI Recovery or eRecovery

---

But what for do you need Factory Reset ( you will loose patches, except the NW patch)?

For the particular cases it is precisely described in OP posts how to do Factory Reset from Recovery or eRecovery (not by booting to the System and resetting there)

If you are about to install Open Kirin Treble ROMs (RROS, LOS, Pie) you must also Factory Reset through Recovery, not through System (upon installing the OK ROM)

TWRP cannot be used for Factory Resetting since it does not support encryption, hence cannot handle Data partition
[Huawei P9 Plus Guides, News, & Discussion] jump_i_was:
Because Android is slow and full of useless files.

The last factory reset dates back to about 1 year ago
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
The Thread was opened at 07.25.2018 - before there wasn't possible to update to Oreo.

And if you have rebranded with HWOTA7 to VIE-AL10 you had about three Factoryreset with Low-level Wipe of internal storage.

So it can't be 1 year ago... ;)

However it's not bad to do a Factoryreset. In this case you need EMUI Recovery installed instead of TWRP.

And doing the reset from settings /System /reset (with wipe of internal storage) it's more effective.
[Huawei P9 Plus Guides, News, & Discussion] jump_i_was:
Sorry, you are right. :D:D

with a factory reset do I lose any patches?
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
No, Network Patch isn't be deleted after this Factoryreset.

But probably Keyboard and Playstore you must reinstall.

Reboot phone after installing the Keyboard.

Android PIE is out.

That would be great, if someone could make a pie for p9 plus...:)
[Huawei P9 Plus Guides, News, & Discussion] ah2hamed:
Thanks a lot for your efforts it helps me to update my P9.

I followed the steps by step till install the patchs

Thanks
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
The only possibility is AOSP Rom from OpenKirin Team.

Omni PIE (currently in Alpha state, but very good)

It's working properly. ;)
[Huawei P9 Plus Guides, News, & Discussion] n20661:
thanks for the tip. I may wait for final release of Open Kirin pie.

[Huawei P9 Plus Guides, News, & Discussion] fuziyou miku:
When I follow the steps, select the change location, it said

ls: cannot access 'C:/HWOTA7//oeminfo/EVA'$'\r''/*': No such file or directory

why this happen ???

What's more I am now in a firmware called test keys, I cannot change this firmware.:):):)
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
Every file as instructed in OP must be copied to the proper place

Also, files must be renamed as described in OP

If script does not find a file (not prepared or not properly named), flash will be incomplete, resulting with Test Keys

Eg, people use Windows 10, don't enabe to see file extansions and append ".zip" to the file name that was already a zip archive.

Or so - resulting that file has a wrong name and script cannot find it

Please carefully double check and repeat the missed step(s)
[Huawei P9 Plus Guides, News, & Discussion] fuziyou miku:
So what can I do now with test keys, I want to back to stock firmware
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
Flash again the Firmware by change Firmware (not location) and use the setting in Windows "Show file extension"

The problem with Test Keys occurs if File extensions are not visible - then you rename one file and get update_data_public.zip.zip (this doesn't work) instead of update_data_public.zip
[Huawei P9 Plus Guides, News, & Discussion] fuziyou miku:
I am sure I do not make this mistake. I has already closed "Hide extensions for known file types" in windows setting. When I flashing again by change Firmware, my phone got into test keys again.
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
Okay, in this case oeminfo of your device doesn't match the Firmware - or, some of the downloaded zip file is perhaps corrupted (damaged)
[Huawei P9 Plus Guides, News, & Discussion] fuziyou miku:
emmmm....then,how to detect which oeminfo is in my device now:eek:
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
Did you move the downloaded and extracted HWOTA7 folder to storage C:/

- the path must be C:/HWOTA7 and not C:/HWOTA7/HWOTA7 (for example)?

The Tool can not work, if it's not on the right path.

You should also check the md5 of the downloaded zip file. If it doesn't match, the Tool can not work, because then some files inside the folder are missing or damaged.

Enter with adb following lines and post the result:

fastboot oem get-bootinfo

fastboot getvar vendorcountry

fastboot oem get-build-number

fastboot oem oeminforead-SYSTEM_VERSION

What was your Build Number before you started to use the rebrand tool? (Model /cust /firmware number)?

What's your intention right now - do you want to go back to your original Build Number or do you want to rebrand and update to Oreo?
[Huawei P9 Plus Guides, News, & Discussion] fuziyou miku:
the results are as follows

C:\HWOTA7\tools\Windows>fastboot oem get-bootinfo
...
(bootloader) unlocked
OKAY [ 0.007s]
finished. total time: 0.009s

C:\HWOTA7\tools\Windows>fastboot getvar vendorcountry

My original built number is VIE-AL10 with Android 7(degraded from oreo) , then I had used your OP to flash AL29c636 and suffered test keys.

Now I want to know whether there is any international firmware has Oreo. if not, I just hope back to China firmware(VIE-AL10) thanks:o
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
This whole method for rebranding to Chinese AL10/AL29 c00 is presented here because THERE IS NO INTERNATIONAL Oreo for P9 Plus (similarly for P9).

This is all written in the OP instructions

Hence, if you wanted to have Oreo, you should have stayed on AL10c00

>> then I had used your OP to flash AL29c636

AFAIK, there is no such model/cust as "VIE-AL29c636" - Open Firmware Finder and Add model under that name

Did you maybe wanted to say L29 c636 (not AL29)?

Also, there are hardware differences between L09 and L29, you should not flash firmware from one to another
[Huawei P9 Plus Guides, News, & Discussion] fuziyou miku:
Oh,haha you are right. It is L29c636

However, when I try to rebrand, it shows

****************************************
* What would you like to do? *
* 1. Change firmware *
* 2. Change location *
****************************************
Select: 2
ls: cannot access 'C:/HWOTA7//oeminfo/EVA'$'\r''/*': No such file or directory

****************************************

****************************************
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
From that moment the change location didn't work - why did you flash a different Firmware to your phone which doesn't match your device?

Which firmware did you flash after that you had Test-Keys?

It's not recommended to flash Firmware for another model of the same device without changing oeminfo!

So, if you would not had flashed Firmware since the change location doesn't work for you - you wouldn't have Test-Keys.

That's your own fault.

On which place to you have HWOTA7 folder on your PC.?

Something is wrong with your configuration.

The Tool is working properly for all. When you get this error it means, the Tool can not find the required files - because the path where your folder is located is wrong or the folder inside the HWOTA7 folder is empty because of a uncompleted download.

Download the HWOTA7 Tool again, check the md5 (if you are know how to do it), extract the zip folder "here"

Copy only the HWOTA7 folder to the main directory on storage C:/ (on Windows and not on Linux and not on Mac)

Make sure, the HWOTA7 folder has not a second HWOTA7 folder inside - because C:/HWOTA7/HWOTA7 can't work.

The path must be only C:/HWOTA7

Make sure, the folders inside of HWOTA7 are not empty except the update folder (which is the folder where you copy and rename the firmware zip files)

Don't change anything on the folder/file structure inside the HWOTA7 folder.

Disable Anti-virus programs on your PC. Make sure you are Administrator on your PC and not Guest.

Then everything should work as it should.

[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
It's a little bit strange. What's happened if you delete just the notification with recycle symbol (on your Screenshot) - does it come again?

I have to check soon I find a Time window.

I am sorry for my small support at this time, but I had to learn for my exam. (new job) Specially this weekend once more, because my final test is soon, probably on Monday.

[Huawei P9 Plus Guides, News, & Discussion] n20661:
Hi There!

I had exactly the same notification (B537 oreo) "failurea2, too some day ago.

My solution was, froced stopped google app, then I restarted the phone, and since then no more problems so far.

If you do not use ok google voice command, or don't you have any conservations with your phone... only touching, you can disable the detailed access of apps to microphone camre etc... in settings.

I hope it was useful.

have a nice day.
[Huawei P9 Plus Guides, News, & Discussion] meshoo00oo:
Yes if I deleted the notification, it comes again.

The problem that I can't disable notification of the security part in the phone manager as attached photos.

And if I disabled the microphone permission in Google application, it stop using the microphone at all during search.

I used an application to block the notification called " notification off [Root]" and it succeeded to disable this notification but sadly it also blocked all notification from the phone manager like the low battery notification :rolleyes:

Also of course I'm waiting the solution for the VOLTE :D

Has your phone SIM Lock?

If yes, you can remove SIM Lock with HCU Client by DC Unlocker
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
You can't lock the Bootloader.

If you would do, all changes for having mobile network and Playstore are gone, because locking Bootloader triggers a complete reset.

I have successfully completed my training for the new job. Now I have a little time to take care of it
[Huawei P9 Plus Guides, News, & Discussion] KobusLG:
Bricked!

I need some help! the B537 update (and some stupidity) bricked my phone!

I got the update, but after it installed I needed to get the SIM patch/gapps on it again. Unfortunately I couldn't get TWRP flashed from recovery. I believe this is because the update removed OEM unlock, and I couldn't get it in the settings any more. I tried flashing various things and image components from recovery, all of which have made things progressively worse.

So now the status is:

- I can get to recovery.

- bootloader unlocked, but oem still locked

- I can flash images, but they don't always work: trying to get TWRP back on never works. It succeeds when I flash the oreo version TWRP (with recovery_ramdisk), but rebooting I just get the stock recovery. trying to flash the Nougat TWPR (with recovery2 or whatever) always fails.

- The stock recovery cant fix things. tried every option of resetting, downloading recovery package etc, everything fails.

- It looks like I can flash images. I can replace the oreo system.img with one from omnirom, and trying to boot I get the OMNI logo, but nothing further; it just tries to start forever.

If anyone has some sage advice, I'd appreciate it. Otherwise I'm going to have to get a new phone....
