Hmmm, for some reason I can't access it. I guess I'll go fastboot way, what are the usual things that I will flash in fastboot to return to stock? Is it only system.img? I am not rooted (no Magisk).
[Huawei P9 Guides, News, & Discussion] zgfg:
You cannot access but what - the app on Playstore, eRecovery (rebooting to Recovery by app while USB charging)?

Make sure to grant root to Reboot app

Usually, you should go through eRecovery, Install latest firmware and recovery.

Maybe possible to do through HuRupdater but IDK and never used (search back in thread, other users posted about)

You could also DLOAD Service repair b528 and then let it update back to b55x - search also through the thread (I did it once and reported about, suggested later to few other users to fix the bricks, some of them also reported back about).

It must be a special EVA-AL10c00 b528, the official Service Repair firmware, in those posts there were a link to download from

Sorry, from my side cannot help you more, since long ago I have no more P9
[Huawei P9 Guides, News, & Discussion] nadliw:
For the record. I just updated to B552 from B550 coming from Kirin.

Unfortunately not like before I cant install TWRP hence no Network on my phone. Not like coming from B540 to B550 my Network is fine.

I might be forgotten step what I did before. I think the new B552 wont allow to make installation via Fastboot.
[Huawei P9 Guides, News, & Discussion] zgfg:
Please read posts before yours - many other users updated to b552 and inatalled TWRP and Network patch with no problem

How to do, which TWRP etc, is still explained in OP posts
[Huawei P9 Guides, News, & Discussion] nadliw:
;)You are correct. Probably I am too sleepy. Forgot the sudo privilege.
[Huawei P9 Guides, News, & Discussion] FioleK:
Could you update download links, please? I want to move from 7 to 8 (on L09 Europe) and all links are broken... Thank you.
[Huawei P9 Guides, News, & Discussion] zgfg:
Oops, seems you are late to the party

pro-teammt.ru aka FirmwareFinder used to host the firmwares for all Huawei models, but they are diss-functional now for quite some time (or maybe they just cleaned up stuff for the old models like P9)

Seems that developer also deleted (or removed his account) from HiCloud

His files on AndroidFileHost seems to be still in place

In the OP post #2 you can also find some links to my Mega, some files can be also found there

I would suggest you to go through the OP post #2 and to download everything you can still find.

And to post here a list of files whose links are dead and you can not find on AFH or Mega

Basically, you will be missing the two firmwares:

-EVA-AL10b399Sp1 (needed to rebrand from Lx9 Nougat to Chinese AL10 Nougat)

-EVA-AL10c00b540 to upgrade to Oreo.

All the rest (HWOTA7, TWRPs, patches for Oreo) should be available on the AFH or Mega

I hope I could find on my old PC also the first firmware and maybe even the second.

Another good soul may still have his copies

If we don't find b540, a newer b550 or b552 should also work

Then, we could arrange to upload somewhere to your Mega or something
[Huawei P9 Guides, News, & Discussion] FioleK:
At FirmwareFinder there is a long list but nothing to download... How could I install b552 or latest Lineage OS... ? I've manged to download P9_E8_540_Kangvip.zip ( https://fex.net/s/vcmvomb ).
[Huawei P9 Guides, News, & Discussion] zgfg:
What is exactly the full name of your current stock firmware?

Look at Settings/About, should be like EVA- L09c432b502 or something

Also, did you unlock the Bootloader?

If not, buy the Bootloader unlocking code - flashing is not possible with the locked Bootloder (no way around)

--

For rebranding to AL10 c00 b540, you must carefully read and follow the OP post #2.

Everything is precisely described there

If some files are no more available from their original links, you should be able to find them on my Mega account:

https://mega.nz/folder/w41RmZKB#IG53JadhjUKgFK8anbctIw

They are organized into folders Nougat, Oreo - connect by the browser, look around, files should be under the same/similar names as in the OP posts

E.g., find the EVA-AL10c00b399sp17a.zip, dowbload, unzip and find the three zip files inside as needed in OP post #2

Similarly, for b40, find the file EVA-AL10c00b540.zip, download, unzip and find inside all three zip files

Once you successfully finish the OP post #2 procedure (rebrand to AL10 c00, upgrade to b540, install TWRP for Oreo and flash Network patch), you should be ready for OTA (to b55x)

For OTA, you must have a valid SIM card, and re-flash back to b540 Recovery (OTA will fail with TWRP).

Alternatively, boot to eRecovery (find and read about in the OP posts) and take Install latest firmware and recovery.

Maybe, update from b540 to b55x could be also executed from HiSuite

---

For LOS, find its thread - there is still a developer and one or two users, posting something once a week or so

Again, read the OP post in that thread with instructions

Prerequisite for that LOS is also this same rebranding and updating to AL10c00 b540 (or higher) - you must also flash the Network patch for Oreo from here before you flash the LOS

--

Good luck. That's the most I can help you (I got also rid off my ancient, although still useful P9, specially once upgraded to Oreo)

[Huawei P9 Guides, News, & Discussion] FioleK:
Should I "debrick" with dload folder on SDcard? Can I use L09 firmware after changing to AL10?
[Huawei P9 Guides, News, & Discussion] zgfg:
As always (all EMUI versions), there is Factory reset (maybe named little bit different) in the Settings, as well as in stock Recovery and eRecovery. Please look yourself

But better uninstall Magisk (if it was installed) and flash the stock Recovery (if TWRP was flashed) before Factory reseting - otherwise, might get a brick
[Huawei P9 Guides, News, & Discussion] FioleK:
I have flashed EVA-b540-EMUI-RECOVERY_RAMDIS.img. DLOAD is not working with L09 files, after 5% it failes (I guess that it check that this is now AL10 not L09). HiSuites says that this phone is not supported and sent me to local service. I've done factory reset with this (above mentioned) EMUI recovery and after second reboot the system starts..

[Huawei P9 Guides, News, & Discussion] nadliw:
I believe you should flash Openkini ROM to get Build Number EVA-AL10 8.0.0.550(C00) then the flashing network patch will successful. Same goes to TWRP.

The current patch here does not working when we updating latest update for P9.
[Huawei P9 Guides, News, & Discussion] Fabuseta:

[Huawei P9 Guides, News, & Discussion] Sir Spamalot:
Is B558 the latest OTA? I'm downloading it right now.

EDIT:

So the new firmware does NOT work with the network patch. Had to go back to B552.
[Huawei P9 Guides, News, & Discussion] dkionline:
558? Patched things maybe, have no fw to check.
[Huawei P9 Guides, News, & Discussion] Sir Spamalot:
Yeah, it's a small ~300MB patch. After installing it, applying the network patch prevents your system from getting past the boot screen and then you're forced into recovery mode that says the installation is corrupted. Even doing a factory reset doesn't fix it so you're forced to downgrade.
[Huawei P9 Guides, News, & Discussion] daveh077:
Is there any fix for this so we can safely go to 558?
[Huawei P9 Guides, News, & Discussion] lo_ol:
Well can someone upload b558? Google says its intended for EVA-TL00 rather than AL10, that might be the problem
[Huawei P9 Guides, News, & Discussion] dkionline:

[Huawei P9 Guides, News, & Discussion] Sir Spamalot:
Hey,

Yeah, I just selected "Download latest full package" and pulled the files out of my device from that HwOUC or whatever folder.

I did receive it originally as a patch which might have been causing the bootloop issue.

I (mistakenly) had the phone update to B558 overnight (forgot to delete that full download package and the phone autoupdated...) and it works perfectly fine now. I didn't do anything after the update (no network zip patching etc.). It just added a couple of apps that I cannot remove (but can disable) but otherwise, Wifi works fine, the language is still English, and since I'm also not really using the phone as a phone but merely a Youtube player for kids, I wouldn't know whether the phone/network services work but Wifi and Play store works fine.
[Huawei P9 Guides, News, & Discussion] daveh077:

Can anyone who updated to B558 confirm if the COVID 19 contact tracing exposure notification service, also known as the "Nearby Exposure Notification API" is still working?
[Huawei P9 Guides, News, & Discussion] Premier4ever:
CONFIRMED!!!!

B558 installed and network patch 2.6 works with it, I downloaded the files Mr. Sir Spamalot gave the link for and renamed them and put them in the HWOTA folder along with the update from sdcard files , used TWRP to format data and wipe everything exempt Version and external storage in advanced wipe, ran the install and chose the ExtSD-FirmwareUpdateScript.zip and waited tell everything installed. Did a factory reset and wiped cache, then skipped all settings and NEVER turned wifi on, went to secuirty, disabled scurespace and allow connection via HDB, enabled developer options and usb debugging.

Installed TWRP, and used the Network patch and restarted normally. gave the phone a few minutes without doing anything and the network showed up and wifi works perfectly.
[Huawei P9 Guides, News, & Discussion] Premier4ever:
You need to use the following network patch, it is v2.6 but I had to modify it and remove the applications installation inside it in order to prevent the boot loop. The original file cuases boot loops.
[Huawei P9 Guides, News, & Discussion] daveh077:
Can you provide your modified network patch file?
[Huawei P9 Guides, News, & Discussion] Premier4ever:
Sure. What was removed are; GoogleCalendarSyncAdapter and GoogleTTS. you can install them afterwards if you want them.

Make sure to read my original post and this one very well and also to start fresh, meaning you have to be on a fresh 8.0.0.540 without the network patch installed. boot into TWRP and format data, reboot into TWRP again, go advanced wipe and choose:

* Dalvik

* Cache

* Cust

* Data

* Internal storage

* Product

* System

* Vendor

Dont choose Version and do the wipe, go to main window and choose install, and install ExtSD-FirewareUpdate.zip and enjoy.
[Huawei P9 Guides, News, & Discussion] daveh077:
What method did you use to get back to 540, I've done this before but usually when something has gone wrong. Also what security month and year is your phone on now with 558?
[Huawei P9 Guides, News, & Discussion] Premier4ever:
What version is on your phone now? the method depends on that answer, I managed to go back to Nougat china version (B399sp17a) or EU version (C432B506) and verse versa using HuRUpdater_0.4.zip ( the phone gets locked and you need to unlock it, and you may relock it again in order to be able to change versions on Nougat and then re-unlock it) then upgrade to Oreo. I bought my phone with Nougat already installed, therfore, I dont know If it will work with marshmallow or not.

Here is what you are looking for:
[Huawei P9 Guides, News, & Discussion] Mine Hashu:
Its so difficult 😐 is there no any easiest way? 😐
[Huawei P9 Guides, News, & Discussion] Tecalote:
There's no easy way to do it.

But for the moment it's more difficult as described. Because some things has changed. The links doesn't work, because Huawei changed the server addresses - when I find some time I have to update.

The network patch for the three models must be updated, cause they doesn't work for the latest firmware.

However, thanks to some users. If you read the last few pages, you can find solutions.

Mega folder with necessary firmwares. Modified network patch - also thanks for this temporary solution.

I don't own a P9 for this time and has a lot of work in my job and have family too.

That's why I didn't do anything since the last update.

I have also a new HWOTA7 Tool with L29 oeminfo.

So if I find any time I must update the whole thread.

Then I will also give credits to some helpful users.

But I think I am not able to do that before the new year.

Hi!

Yesterday after unlocking the phone, I try to rebrand it with HWOTA tool.

Use the Change firmware option and finish successfully.

Then the phone started in bootloop and rebooted in the Huawei eRecovery bootloader. It prompted me to do a factory reset due to the error, and continue to bootloop.

Since then, although I can enter fastboot mode, it does not allow to script TWRP (FALIED to write recovery2 error) and it does not allow to continue.

If I try to update from the Huawei bootloader from the SD card, it´s stuck at 5% and failed the process (with several different versions of ROMS of the EVA-L09).

Please HELP!!!

Sorry for my English

From already Thank You very much
[Huawei P9 Guides, News, & Discussion] zgfg:
IMPORTANT NOTE:

I'm running out of space on my Mega site while I have actually dismissed all my Huawei phones 2+ years ago

On the other side, I have just obtained my second Xiaomi and I shall start filling the Mega with its resources and ROMs (with no other option but by deleting in parallel the old Huawei P9 ROMs)

Hence I'm asking @Tecalote, @maartenjd and other P9 (Oreo) users, please if you want to save those 13.7 GB of P9 Nougat/Oreo stuff, please download and copy (and publish for future users) to your own clouds on Mega, AFH or else

Since Huawei removed the old ROMs from their servers, most of the links in P9 HWOTA7 thread OP instructions are dead. However, at the time when I had my P9 phones, I upoaded all the needed to my Mega:

File folder on MEGA

mega.nz

Of course, rebranding and upgrading to (Chinese) Oreo by HWOTA7 are prerequisites for using ECOKernel, moving from L09/L19/L29 stock to the Treble ROMs like LOS (project still alive) and the (abandoned) P9 Open Kirin ROMs. Also, the same HWOTA7 stuff will be needed in case of bricking the Oreo or if somebody wants to go back to the Lx9 Nougat

You can contact me by PM that I could schedule cleaning the P9 ROMs based on the order you download and back-up to your clouds
[Huawei P9 Guides, News, & Discussion] Tecalote:
Hi, if you didn't follow the steps it cause problems like the one you have.

For debranding it's necessary to change location (region) first and then install the right firmware for the new region and Android version.

Every step is necessary and no step can be skipped.

In the moment you must check your systeminfo with following steps:

Boot into Fastboot Mode and enter this commands (only one by one of them and post the results here):

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

[Huawei P9 Guides, News, & Discussion] Tecalote:
C605 = Latin America, Colombia, Panama, Guatemala - should be identical with hw/la

That means you must install by dload method EVA-L09C605B393 to get your phone working back.

You need a full version of this Firmware, OTA Firmwares doesn't help.

The problem is to find this Firmware anywhere to download.

One popular site is androidhost.ru but it's not there. I checked. I can try to find it, but this needs some time, probably some days.

@SSSGUNSSS Please download the Firmware to unbrick your device EVA-L09+L19_C605B399SP01_Andr7_EMUI 5.0.1 from here:

https://mega.nz/file/zIhmGBrR#qA4Xcp_2G6dZQyucwSrndy3P0nK_63NMQVvmlOLrdVw

1) unzip the zip file

2) you need a MicroSD Card and it must be formatted as exFAT (not NTFS, not FAT32)

3) copy the folder dload with the content inside as ist is to the main directory of your SD Card (dont place it in a subfolder).

4) your P9 should have 30 - 50% battery - if it is empty, and normal charging does not work - you must first boot into Huawei eRecovery mode and charge your battery there (with USB cabel to power and with key combination Vol+ and Powerbutton you can enter eRecovery and here charging should work) - you cannot do the update with Power cable, phone must be charged

5) if battery of your phone is charged, press the volumne butten in the middle between VOL+ and VOL- down and press the power button at the same time and keep holding this combination until phone starts into EMUI Software Installing. Then release the buttons and wait until the update is finished and after your phone should work again.

[Huawei P9 Guides, News, & Discussion] SSSGUNSSS:
Hello!

During this week I tried in every possible way to install the ROM but it keeps saying the same error, installation failed at 5%.

I tried to do it with two different memory cards (One of 8GB and another of 32GB formatted both in exFAT)

Extract the ROM version C605B399 to the dload directory, even tried with other C605, but continues failing at the same percentage.

I really don't know what the problem might be.

I have no more chances, maybe the last one might be to buy the same phone from this region (for example with a broken screen), see if you can extract and get it the ROM. Or in case of defect, change the phone module. But this will be more cumbersome.

I honestly don't know.

Any ideas what I may be doing wrong??

Thank you very much again!

Greetings!!

PS: sorry for my english
[Huawei P9 Guides, News, & Discussion] Tecalote:
Your English is fine (mine isn't better) 🙂

I think, the problem was created since you didn't change the region and flash Android 7 Firmware for the changed region (which is required) before updating to Oreo.

So you missed necessary steps. That's why you are now on the invalid build number System 8.0.0.046(29C9) - which is the incorrect result.

Now you are on Oreo, but Firmware doesn't match the region.

It seems the phone doesn't allow you to Downgrade to the original Firmware of your phone.

That means, your hard-coded "oeminfo" is little bit damaged.

Only possibility would be to change the region to all/cn = C00

But this cannot be done at the moment with board steps. Only possibility would be to use the Tool "Chimera" or "DC Phoenix" for change the region in oeminfo. But this isn't free Software, it costs about 15 credits.

With this step your phone probably would start into the actual Oreo Firmware, which you have flashed by missing steps.

But then the Firmware needs factory reset and probably some more steps to work as it should.

It's not easy to repair the phone in this state.

It's bad that you are so far away. If you were nearly to my country - for me it would not be difficult to repair this.

It is much more difficult to try to explain.

So, your idea - to make one phone from two - is even a possibility.
