There were also other users (posts) who later similarly unbricked by using that Service repair b528 package
[Huawei P9 Guides, News, & Discussion] Tecalote:
What did you do, what is the main reason why you brick the phone?

The system information - which you have posted before - looks not so bad..

So I can't imagine for now, what you have done that phone stuck at booting.

You said, you tried to flash different Roms.

But you are already on EVA-AL10 8.0.0.552(C00). So the only one firmware you should flash is the same one. Not any other!

But for unbrick you can't use OTA Firmware, you must find the Full Firmware, perhaps on Androidhost.ru and flash it with dload method.

You can try what @zgfg mentioned

Or you can try to boot to Huawei eRecovery (P9 with USB Cable plugged to PC or charger, Vol+ and Vol- and Power Button) in eRecovery use "Download latest version and recovery" to restore current firmware.

Soon, phone is unbricked, you should be able to Downgrade as mentioned here:

Thank you, @zgfg and @Tecalote for the fast reply, this link saved me.

I tried to dload with the wrong ROM that was the problem. I downloaded that EVA-AL10 6GB one from Androidhost.ru and I unbricked it. And with the sim patch my sim work's fine too.

Thank you for creating all this and still maintaining this thread!

Hi folks!

I also tried to prepare phone for custom roms and foloved this instructions here on post #2. Unfotunately important links are not active any more and here I made a mistake. Really need help/advice.

On the description of custom rom https://xdaforums.com/t/rom-treble-microg-lineageos-16-0-for-huawei-p9.4078383/#post-82201985

there is a link for neccesary files to met pre-requisites to update to EMUI 8.0 firmware. (See update2 in hidden content)

I assume, that there on this MEGA cloud are all necessary files for rebrand and update to EMUI 8.0 firmware.

15.94 GB folder on MEGA

32 files and 6 subfolders

mega.nz

So what I have done. On step 8. I put in the folder C:\HWOTA7\update probably the wrong files. They were stored on MEGA in the P9-eva\Oreo\B552-AL10C00 subfolder. So firsty I changed oeminfo (2.EVA-AL10C00) and continued.

Clearly the tool HWOTA7 didn't complete next step (9). Sorry no printscreen. There was no automatic factory reset. I power off the phone my self with power button and then boot into TWRP (pressed only VOL+).

After that I boot to system (as normaly), suprisely seems to work. But wasn't as described (Accept the terms and conditions (Huawei + Google Services)). However phone has no IMEI, model was changed to AL10, android version 7.

After reboot I felt into boot loop. The only thing now is that I can boot to recovery to twrp or command via ADB. Bootloader is unlocked at the moment.

fastboot devices - MWS7N17210000056 fastboot
fastboot oem get-product-model - (bootloader) EVA-AL10
fastboot getvar vendorcountry - vendorcountry: all/cn
fastboot oem get-build-number - (bootloader) :NRD90M test-keys

fastboot getvar rescue_enter_recovery - (bootloader) This is sec phone!!
(bootloader) NOT secboot recovery image!
getvar:rescue_enter_recovery FAILED (remote: FAIL:verify secure image fail!)

fastboot oem oeminforead-SYSTEM_VERSION - (bootloader) :EVA-AL10C00B398

So what to do next to unbrick this phone? Any help is welcome!

My mother has another P9-eva which she uses every day and I want to flash with custom rom too.
[Huawei P9 Guides, News, & Discussion] Tecalote:
You must flash from the Nougat folder EVA-AL10B399-SP17a with HWOTA7.

This will restore the phone.

But for the update to Oreo you shouldn't use B552 - it's the only one in Oreo folder.

I will upload necessary Firmwares during this week, the upload will be need several hours.

After that I will correct the not working links in OP and tell you what to do further.
[Huawei P9 Guides, News, & Discussion] kundifon:
I did as you described. Phone is working now. @Tecalote vielen dank!

My observations: chinese "letters" can you find everywhere, no google services, play store and apps.

On early stage of this last treatment, phone booted and asked for password to decrpyt partition and scared me with chinas keybord. I entered bootloader code, as few days ago in twrp. (if this is maybe related). Now phone said correct pass and partition data corupted, automaticly did format and then was all right.

I will wait for neccesery firmware update for Oreo. No rush, Tecalote.

It there be the same procedure for both phones from this point on?
[Huawei P9 Guides, News, & Discussion] Tecalote:
Good to know that phone booted now.

Question 1: How is the build number of the phone from your mother? (settings "about the phone" Line: Build-Number).

In the meantime until I have uploaded the Firmwares you can try just install Google Playstore from here:

https://www.apkmirror.com/apk/googl...-0-28-21-0-pr-454913451-android-apk-download/

If this doesn't work, then use this:

https://www.apkmirror.com/apk/googl...-0-28-19-0-pr-454913451-android-apk-download/

The phone should have hidden Google Services in the Nougat Firmware and after installing Playstore, you can try to update apps and services and reboot phone.

If it works you can login to Google and download another keyboard and personal apps.

Optional you can also try additional to the Playstore to use Google Play Services Updater:

https://www.apkmirror.com/apk/googl...ervices-updater-22-6-45-android-apk-download/

If this doesn't work, you can try this:

https://www.apkmirror.com/apk/googl...ervices-updater-11-4-23-android-apk-download/

If you login to Huawei ID and update all Huawei Apps and open them on by each other you can change the region to your country and the Chinese Huawei Apps should be shown in your language.

Question 2: To you have mobile network?

Do you remember how was the Build-Number of your phone before you did change the phone to EVA-AL10C00?
[Huawei P9 Guides, News, & Discussion] kundifon:
I was few days off, now I colleted infos.

Answer 1: Mother phone is stil untoched EVA-L09C703B392

Answer 2: Flashed phone, I tested with SIM. No service, and there is no IMEI number.

I have the box with label and original IMEI from phone. Before change to EVA-AL10C00, most likely was the same build as Mothers. Both was bougt in Slovenia (EU).

I'm interested only for one of available coustom rom. Stable coutums rom are way better than stock.

Thanks in advance @Tecalote
[Huawei P9 Guides, News, & Discussion] zgfg:
If you are already on Oreo, you need to flash Network patch as described in the OP post #2

Btw, for downloading b5xx Oreo firmwares, see:

[Huawei P9 Guides, News, & Discussion] Tecalote:
OP - Post #1 is updated

Uploaded the P9-EVA-HWOTA7-v1.2.zip to MEGA - Link can be found here - see line: Download

Since Huawei Links are down, and Firmfinder is a bit tricky to use, Version 1.2 includes all required Firmwares for rebranding, update to Oreo and also going back from Oreo to Nougat and rebrand back.

Added

: oeminfo for EVA-L29C636

Post #2 (Instructions for update to Oreo) will be updated soon, and also following Post #3, Post #4 will get an Update

At least I search for a cheap P9 to create/manage/test a

new network-patch

for B558 for original EVA-L09, EVA-L19 and EVA-L29 on EVA-AL10 - with a different way than the others, which are just working until B552. (I had no P9 the last 2 years and also no time, to do it).​
[Huawei P9 Guides, News, & Discussion] GreggeryPeccary:
First of all I would like to thank @Tecalote for his work and very detailed tutorials. Thanks to those tutorials I managed to rebrand my P9 and to move from Android 7 to Android 8. Unfortunately I did not follow the instructions step by step and I upgraded from B552 to B558 using the Android updater, before realizing that the nework-patch is only working for certain firmware versions.

Now I'm in the situation that:

- The network-patch does not work -> boot loop

- I followed the instructions for updating my Oreo and used this to downgrade to B552 -> boot loop

- I recover using eRecovery "Download latest version and recover" , which takes me back to B558

Do you have a suggestion for me how to proceed?

I can image:

a) Waiting for a network-patch working with B558

b) Going back to the beginning and downgrade to Android 7 -> this I would like to avoid and I'm not even sure if it would work any way, because all instructions are based on different versions and I'm now on B558

c) Somehow avoid the boot loop when downgrading to B552

Of course I prefer option c). Would it help to also kernel image for B552 to avoid the boot loop?
[Huawei P9 Guides, News, & Discussion] Tecalote:
I ordered a Huawei P9 to create a new working network patch and test it.

In the meantime recover B558 by Huawei eRecovery.

Then use HiSuite to Downgrade to Android 7 or use the Downgrade Tool, which is uploaded in the new HWOTA7 Tool in the folder 1. Firmwares (Download see Post #1).

When you back to Android 7 (AL10) update again to B552 and use existing network patch - but do not upgrade to B558 until I managed the new network patch.
[Huawei P9 Guides, News, & Discussion] zgfg:
What exactly is your current firmware. Read by executing from Fastboot:

fastboot oem get-product-model
fastboot getvar vendorcountry
fastboot oem get-build-number
fastboot oem oeminforead-SYSTEM_VERSION

Ie, are you exactly on EVA AL10 C00 B558?

If on EVA AL10 C00, use service repair package to fix/downgrade to b528:

https://xdaforums.com/t/rebrand-update-tool-hwota7-p9-eva.3820849/post-86594701

From b528 you can manually upgrade to eg b552 or so (see the post #2172 below) where network patch and everything will work
[Huawei P9 Guides, News, & Discussion] GreggeryPeccary:
* EVA-AL10

* vendorcountry: all/cn

* EVA-AL10 8.0.0.558(C00)

* EVA-AL10 8.0.0.558(C00)
[Huawei P9 Guides, News, & Discussion] zgfg:
Ok, AL10 C00, you can proceed with Service Repair as described

Later, to find and download b535, b552 or so for manual upgrade, see:

https://xdaforums.com/t/rom-treble-microg-lineageos-16-0-for-huawei-p9.4078383/post-87049377

You can also:

- download P9-EVA-HWOTA7-v1.2.zip from the revised OP post #1

- go into HWOTA7, 1.Firmware and extract 2.EVA-AL10C00B552.zip

Inside you will find the three update*.zip files for DLOAD from b528 to b552
[Huawei P9 Guides, News, & Discussion] GreggeryPeccary:
Ok the dload method worked for me - now I'm on B528.

Thanks for the advice!

Even calling *#*#2846579#*#* worked :)

Now the question is do you think the update method (described in #5) going to B552 will work.
[Huawei P9 Guides, News, & Discussion] Tecalote:
It will work.

You need just to flash the Script from #5 with TWRP for Android 8.

And the HWOTA folder on external SD must contain from B552 the

update.zip

update_all_hw.zip

update_data_public.zip

The Script (like described in #5) and the Nocheck Recovery
[Huawei P9 Guides, News, & Discussion] GreggeryPeccary:
Upgrade to B552 and installing the network-patch was successful.

Thanks alot!

Hi everyone. Its been some time since I last interacted with this thread, so apologies in advance for not "understanding" some of the concepts anymore.

I've rebranded my L19 to AL10 and added a custom ROM (LineageOS). But since I'll be giving the phone to a relative, I want to rebrand it back to L19. The problem is I don't know how to remove the custom ROM (or go back to the stock AL10 ROM). I have b550 installed.

I tried using HWOTA but I'm getting the "partition length get error" message.

-----------------------------------------

Okay, update. I was able to go back to stock b550, but with just one sim card slot working. I'm going to try rebranding it back to L19 now.

-----------------------------------------

LAST UPDATE:

Was finally able to rebrand back to L19. Whew! (All it took was a bit of searching in the thread)
[Huawei P9 Guides, News, & Discussion] Tecalote:
@_gabriel120pro_| In which process did this error occur? What was your intention to do, or did Hwota_eng.bat not start at all? What firmware are you currently on? You know that you cannot downgrade from Android 8 to Android 7 with the tool, but that there is a tool for the external SD card (which is available in the firmware folder). I need more details on which process the error occurred. I can do a few tests tomorrow at the earliest. Upload everything if necessary.
[Huawei P9 Guides, News, & Discussion] _gabriel120pro_|:
The error occurred when booting update_eng.bat only showed the "Created by" boot message and then gave the error, I went back to Android 7 firmware with the Downgrade 8 to 7 method in the firmware folder, my intention was to update to the version (B552) using the script but it progressed and I could not do it

-P.S

I search in Google the error code where I found a post on stackoverflow saying that some cygwin commands are not compatible with 32 bit systems ( I have Windows 10 32Bits ), I am going to install Windows x64bits to check if this is the cause of the error mistake

git fails from IntelliJ on Windows 10 with fork: can't reserve memory for parent stack

I'm not sure what the cause for this problem, but git fails since I upgraded to Windows 10, from IntelliJ only. Whenever I use it from SmartGit or Cygwin CLI, everything works as it should, but ru...

[Huawei P9 Guides, News, & Discussion] _gabriel120pro_|:
@Tecalote Well, I managed to run HWOTA on Windows x64, so I think the script doesn't work on 32 bit systems, now I come a new problem, I was going to rename the phone to EVA-AL10C00 using the script, use option (2. Using the script) and then (2. Change location) to which the tool throws me an error (happens in v.1.1 as in v1.2)
[Huawei P9 Guides, News, & Discussion] urbanmec:
1. You will receive Chinese firmware updates from that point on. (for the rebrand model not original)

2. You will (Probably) lose root access and custom recovery.

3. You will (Probably) have to re-root your device everytime and make the necessary changes to adapt rom to your device (Network , NFC , ....etc).

PS. 2 and 3 are probable because it all depends on the update type (full or partial) and the update method (manual or via stock updater and recovery).
[Huawei P9 Guides, News, & Discussion] Tecalote:
"Maybe there was a failure with flashing Data for c185 or something" - yes, this could be. It is always recommended to open the downloaded zip files with a zip viewer (open as archive) - if it is possible to open, it should be okay. If you get an error, the zip file is corrupted.

"Leaving L19 c185 b402 as that for tonoght, otherwise it looks fine." - Good news :)

"As you say, I will tomprrow flash c185 b402 by HWOTA first to have it clean before rebranding to AL10" - highly recommended :good:

[Huawei P9 Guides, News, & Discussion] Tecalote:
[MENTION=7950549]Twisted Prime[/MENTION] Did you manage in the meantime mobile network?

I am asking, because I know now, it's primarily a permission problem.

Yesterday I made same tests with Viper and was finally not able to boot anymore.

I restored b528 with eRecovery (Download latest version /WLAN)

So I started from the beginning on b528.

I made the Lines in local.prop and was sure, everything should be right.

I had no Dual SIM settings in Network & Wireless.

I controlled everything once again and I saw, the local.prop file had permissions 777 instead of 644.

That's why - if you add the lines:

1) There should be no space at the end of the line

2) Once you've saved and closed the file, click Refresh in the window and check permissions again - it must be 644

3) Reboot. Then you should have Dual SIM in Wireless & Network settings

Hi Fabio,

if you do it exactly as described, you shouldn't have any problem.

[Huawei P9 Guides, News, & Discussion] Tecalote:
Yes, I know that Windows 10 is not Windows 8.1. :cyclops:

You must have enabled Developer Options in Phone Settings ("About phone" 7x click on Build Number)

In Developer Options enable 1. ADB Debugging 2.USB Debugging (in this order) OEM-Unlock must be enabled

Bootloader must be unlocked.

In Windows 10 you use right click "Open command window here" Then you type:

adb devices (this should list your device with SN - make sure you accept the RSA-Fingerprint request, which comes at that moment on your Phone)

adb reboot bootloader (this will reboot your phone into Fastboot Mode)

fastboot devices (your phone should be listed with SN in Fastboot mode)

fastboot flash boot AL10-b399-patched_boot.img (this will flash the boot.img - explained in Post #2)

fastboot reboot (this will reboot your device to system - you can disconnect USB)
