Houston! We have a problem!

Hi there :)

ok first thing first, thank you because the process did work, "in some way"...

that'd be 'cause I was (apparently) able to debrand my VIE-L09 and get rid of that hideous provider (TIM, Italy) contaminating and littering my device.

So, now their logo and stuff seems to be gone (...forever?)

But that achievement was not painless.

At first I installed the "VIE-AL10" with the consequence that the phone IMEI DISAPPEARED!!

I almost freaked out, then I repeated the process and installed the VIE-L09c432.

The IMEI came back (whew!) BUT...

...now I'm stuck with this "NRD90M test-keys" thing, which is a very scarse version of the OS, and does not even contain a file explorer (ok, files can be accessed from the "download" utility) or themes or all the google stuff, such as play store, and so on.

I tried both to "dload update.app install" and "twrp zip install" a no brand version of the ROM originally installed in the phone (VIE-L09C55B388, Andr. 7.0) but the installation stops at 5% and then a threatening red exclamation point appears, telling me everything was screwed up.

I also tried some other stock ROM and a "rollback utility", in the hope that downgrading the OS might have worked but nothing: nothing can get installed in the damn thing, no matter what I do I always get stuck at 5%.

I am nothing like a coder, nontheless I have debranded, rooted and flashed a bunch of stuff before and everything went "linear", I never had the problems I am having with this P9 plus: everything I tried to make it work simply FAILED.

Now, so far this "HWOTA7-P9-PLUS-VIE" is the one and only utility with which I was able to install "something" in the damn phone. So I thought to use it in order to install a ROM other than the ones included in the utility package.

Now "the" question:

In one of your posts you state: "If you click in Firmware Finder on Download you will see 4 zip files - but you need only 3 of them"

Now, there is no "firmware finders" nor websites of any brand and kind where I could find more than 2 (TWO) files for the same ROM: the "OTA-MF" and the "full OTA-MF".

In the Utility, besides the ROM, there are a number of "info files" contained in the "oeminfo/VIE" folder.

Apparently, those are the ones generating the list of the available ROM options in one of the screens: how can I get/make/use those files for a ROM that might suit my needs?

In a few words: how do I get out of this mess and install a full featured well working no-brand ROM before I take this phone and use it as a nutcracker? I would rather NOT install OREO and stay with Nougat.

Thanks a bunch for any reply/solution you may be willing to give me...

>:-@

BTW, I "bought" the bootloader unlock code from DC-Unlocker and, by mistake, I also got some other (4) "unlock codes" (NCK, NetSub, SP, Unblock) with which I dunno what to do. But I have them, in case they are needed, (otherwise... 4 euro got wasted...) :rolleyes:.
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
Process should work flawlessly, but did you carefully follow the OP instructions?

It clearly says in the post #2 that you will 'temporarily' loose IMEI - that's why you had to continue by instructions and install the Network patch....

See attached screenshot from the OP post #2, "You will have unknown IMEI....that is normal..."

If you did follow and install TWRP for Oreo, and from that TWRP flash the provided Network patch, etc - at the end you would have IMEI back, Mobile network, etc
[Huawei P9 Plus Guides, News, & Discussion] endlessquest:
Hi :)

thank you for your quick reply.

I did my best to follow the instructions by the book.

I did get my IMEI back by installing the "VIE" version of the OS

I am not inclined to install Oreo just yet, consider that I really like Lollipop and I noticed that the higher the version, the lesser freedom of action you have (like installing software, rooting, etc...)

I ask myself why I can't install anything by the ordinary methods, such as dload.

I realized that the original version would re brand my phone, and I don't want that. I'd rather installing a previous version, B370 "generic europe" for instance, no brand. But to do so I need the oeminfo file to insert in the utility and I wouldn't know where to find it..

for any purpose, I'll post my progress in restoring my phone
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
Rebranding back to L09-c432 should work through HWOTA7.

Changing location must flash its OEMINFO.

After that, you could DLOAD a FullOTA service repair package from

https://androidhost.ru/search.html

Make a search for VIE-L09c432, you will find b387 and b386:

https://androidhost.ru/6pf

https://androidhost.ru/bww

https://androidhost.ru/67T

These are Huawei's so-called service-repair firmwares, you can force DLOAD with them.

Upon downloading, it must be unzipped (and unarjed if archived),

you will find Docs and Software folders.

In Docs folder there must be Huawei's manual with instructions for DLOAD - please carefully read.

In Software (folders migt be zipped/arjed) there must be three update*.zip files.

You must copy them to /DLOAD folder on the SD card.

These three files must not be unzipped or renamed - please carefully read manual from Software folder.

Maybe that package is common to VIE-L19, in that case Software folder will contain

the fourth update*.zip file corresponding to L19 -

you must omit that file (all must be explained in the DLOAD installation manual included).

Then you switch off, press and keep pressing Vol+ and Vol- simoultanelesly, and boot by Pow.

It must start DLOAD.

At the end you could make Factory reset from eRecovery

(switch off, press and keep pressing Vol+ and boot by Pow)

---

However, HWOTA7 should have been started only from Nougat (that's why it's named HWOTA7),

but you apparently performed it directly from Oreo (b537)

-upon you rebranded to AL10c00b537 and before you finished the job

by flashing TWRP and NW patch to repair IMEIs, to make Mobile NW and NFC working and to clean from bloatware

Before rebranding back to L09-c432by HWOTA7, you should have rolled-back to AL10 Nougat.

In the old days, rolling-back worked from HiSuite, but some say it may not work anymore with the newer HiSuite.

Now, before continuing, you should better inspect by fastboot where you are really now

(your phone, on Nougat or Oreo, on L09c432 or AL10c00):

fastboot devices
PAUSE
fastboot oem get-bootinfo
PAUSE
fastboot oem get-product-model
PAUSE
fastboot oem get-build-number
PAUSE
fastboot oem oeminforead-SYSTEM_VERSION
PAUSE
fastboot getvar vendorcountry
[Huawei P9 Plus Guides, News, & Discussion] endlessquest:
Thanks again for following my "case" (it's so frustrating...)

As I said, the ROM contained in the phone, before debranding, was Nougat and I never installed Oreo not before or after.

I am downloading the androidhost-ru/bww file, It takes forever since apparently download speed is limited to somewhere around 100/140kb/s, so considering that I get disconnected from the server quite often, I guess it'll take something like a day or so to download the file, "if" I'm lucky (unless you can provide me with an alternative, faster mirror).

That to say I most likely won't be able to do much, today

One thing using the HWOTA7 utility: the flashing was apparently successful, although the installation seems to "stall" around 57% to suddenly "jump", then, to 99% and then finalize.

I'd like to install the VIE L09C432B370 eu ROM, but I would need the appropriate oeminfo file, which I don't know how to obtain.

dload update attempts get stuck at 5% as usual, unlocking bootloader makes no difference

Apparently I can't post attachments, or I could show you some recurrent error messages I get when I try flashing.

"error 7"; "password not matching" and similars

I was thinking, since it was branded, that the provider put some kind of lock to prevent debranding.

As I said I have a bunch of unlock codes but I dunno what to do with them.

For instance, do you know anything about this "password" deal?

I appreciate you help
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
Open an account at androidhost.ru and downloading will go faster

By fastboot results it seems you are ready for DLOAD with L09 Nougat

But before flashing c432, make sure you do (or that you did) HWOTA7 change location to c432
[Huawei P9 Plus Guides, News, & Discussion] endlessquest:
YESSSSSSS!!!!!!!

I'm off the hook!!! :victory: now I've got the VIE-L09C432B370 in my phone and it seems to work just fine, so far.

now... what did I do...?

After a long wait, I finally received the file you linked me.

My phone's oeminfo was still stuck on "NRD90M test-keys".

I unpacked the compressed files, copied in the ExtSDcard and gave it a shot to flash it.

And I got REE-JECTED! AGAIN!!! :mad:

So, I went back to the HWOTA7 utility because I wanted to change location to c432, as you suggested.

In order to achieve that purpose I did the following steps:

- using the finder app, installed in the phone, I found the links to the B370 ROM, send the links to my PC and downloaded them from there; I actually got three files (not two, as it happened with links found searching the web),

- then I removed everything from the "HWOTA7/update" folder,

- I replaced the content with the B370 ROM and renamed the three files accordingly to what's recommended by the guide.

- I also removed everything from the "HWOTA7/oeminfo/VIE" folder, with the exception of the "VIE-L09c432" oeminfo file.

- Then I followed the "script/change location" procedure selecting the one and only info file left in the utility, so that there was NO DOUBT that was the ROM I was installing.

everything went smooth and the firmware got installed... THEN!!! (son of a gun!) when I thought everything was ok...

- it didn't boot and I was asked for a password!!! AGAIN!!! :mad:

I rebooted the system a couple of time: no way to get out of there.

SO, I had an "intuition": the bootloader got locked during the installation process!

- thus I fastbooted my phone and used ADB to "fastboot oem unlock + bootloader code" and unlock it.

- then I went "fastboot reboot".

The system did its job and...

EUREKA!!!

it stopped asking me for the password and I ended up with a full featured (and working) no-brand B370 Nougat freshly installed!!

Boy I was so happy, after so much trouble...

Now this is the current situation of my phone:

fastboot oem get-bootinfo

(bootloader) unlocked

fastboot oem get-product-model

(bootloader) VIE-L09

fastboot oem get-build-number

(bootloader) :VIE-L09C432B370

(no more NRD90M test-keys!!!) :laugh:

fastboot oem oeminforead-SYSTEM_VERSION

(bootloader) :VIE-L09C432B370

(again!!)

fastboot getvar vendorcountry

vendorcountry: hw/eu

So I guess everything went fine... I'm kind of "scared" to update it!

Now it's ROOTING TIME!!! :laugh:

Would installing the TWRP and SU 2.8 be enough to do the job?
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
SuperSU is old but if you are used to and you only need root (not hiding it), you can try.

I have no more EMUI 5 and Ilast time I used SuperSU maybe three years ago.

Magisk is newer but you need to learn about before going to use. Also, don't know if the latest official is still good for EMUI 5, or newer but Canary builds are better for EMUI 5, or the old v19.3 is needed (there were some issues with particular versions a year ago when I last time used Magisk on EMUI 5)

You will need to search elswhere, this thread is about EMUI 8 + Magisk, and there were not many users (to answer and help)
[Huawei P9 Plus Guides, News, & Discussion] endlessquest:
hi :)

well I've been using SU for quite a while, now, so I'm kind of handy with it.

I don't know magisk but I'd like to learn about it, especially if it works better than SU.

One of the reasons why I am reluctant in upgrading my phone's system is that rooting doesn't seem to work on newer versions.

BUT if magisk does the job it is a very good thing. I'll check around and see.

Anyway, android 7 and emui 5 work like a charm, to me: I ask myself whether it is really worth upgrading to Oreo...

edit: I wanted to update the B370 I have installed to a newer version, from the ordinary "settings/system update" in the phone, BUT it didn't work... it said "no updates", period.

SO I "dload installed" the ROM from the link you provided me, B386.

result: It worked like a charm!

It was well worth waiting for... FOREVER to download it...

AND it seems to have definitely FIXED my phone: that ROM has everything and I was able to upgrade it to B387. :good:

thank you again for giving me that link, I would have NEVER found it by myself ;)

although I have a P8 with lollipop installed and... I kinda like better the way it looks... :)

I hope I will be able to root the phone with the B387 installed...

anyway: GOD BLESS XDA-DEVELOPERS!

when it comes to mobile devices, this is an irreplaceable source of information.

thanks a lot to all of you guys, your activity is so much appreciated
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
If you continued by Oreo, you would have instructions for Magisk in the OP post #4

But you can also flash Magisk with Nougat. Read installation instructions:

https://www.didgeridoohan.com/magisk/HomePage

https://topjohnwu.github.io/Magisk/

Of course, unlock Bootloader and enable OEM unlock from Developer options before flashing

Unzip update.zip that you downloaded from androidhost.ru to obtain update.apk.

It must be update.zip corresponding to your current b386 or b387 - if you later updated by OTA, see below for alternative approach.

Open XDA Huawei Update Extractor thread

https://xdaforums.com/showthread.php?t=2433454

download and install to PC Windows.

Open update.apk and extract boot.img and copy it to the phone.

That will be your stock boot image, keep in case you ever get bootloop with Magisk - you can then flash it from TWRP or fastboot to remove Magisk (dirty but working method)

Alternatively, you will need TWRP for Nougat (not for Oreo), you can install it by HWOTA7 method.

Boot to TWRP, go to Advanced, Terminal emulator and execute:

dd if=/dev/block/bootdevice/by-name/boot of=/external_sd/boot.img

You will find disk-dumped boot.img on the phone, Internal memory

From XDA Magisk Canary thread:

https://xdaforums.com/apps/magisk/dev-magisk-canary-channel-bleeding-edge-t3839337

post #1, download Magisk Manager apk (take release, probably you won't need to debug - if necessary, you can always switch to debug)

Install downloaded MM, open its Settings tab and change the channel to Canary release

Then go back to the main page, scroll down and open its Advanced settings and check in buttons to Preserve encryption and AVB (both)!!!

Take install Magisk from top, choose Patch method, you will have to navigate to the boot.img you extracted or disk-dumped before.

Find the patched boot image in Downloads folder on Internal memory.

Boot to TWRP, take Install, choose Install img, navigate to the patched boot img and install it to Boot.

Reboot from TWRP to system, open MM, it must show that Magisk was installed.

Voilla

PS: If you already installed SuperSU and want to switch now to Magisk, you must completely clean off SuperSU.

There was an option for full unroot in the SuperSU apk, and there used to be an un-installation zip for TWRP for that purpose
[Huawei P9 Plus Guides, News, & Discussion] endlessquest:
ok.

- As I said, I am not very interested in switching to Oreo, unless there is a real advantage/gain in doing so, which I never really found every time I upgraded a ROM to a newer version.

- OEM unlock is disabled when the bootloader is unlocked, it is available only when it's locked. Anyway I kept the phone bootloader unlocked.

- I saw that Magisk installation is kind of tricky, so if I can avoid going thru pages and pages of tutorials I would, unless absolutely necessary.

- I don't care about "hiding" rooted apps, I never did and I don't see why I should, maybe you can explain this to me.

- Also, I am ok with SuperSU, as long as it does the job of rooting the phone so that I am able to install some utilities that I consider "crucial" to have.

THE PROBLEM NOW IS:

- I tried to install "twrp-3.3.1-0-vienna" (apparently the latest version) using ADB-Fastboot but, although everything seemed to be ok, it didn't get installed and I had the factory recovery instead.

- Then I used the one in the HWOTA7 utility, TWRP got installed but the phone got STUCK in a bootloop.

This on B387 ROM.

- So, all I could do to get out from there, each time, is repeating the HWOTA7 procedure, go back to B370 and then upgrade to B386 again.

- Now I am on B386 and I'm not upgrading just yet until I find a solution, thus a matching TWRP; to me I can stay in B386 for... FOREVER, as long as I can have my phone rooted.

The question is: which TWRP version should I install?

I searched both in this forum and the web for a version suitable for the VIE-L09C432B386/B387 ROM but I couldn't find any specific info about it.

Any hints would be very appreciated :)
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
No problem, you stay on Nougat and SuperSU, your choice and preference.

Since this thread is mainly about Oreo
[Huawei P9 Plus Guides, News, & Discussion] endlessquest:
well, the 3D title says "rebrand update HWOTA7" so I believe it's about Nougat and since I did have problems in "rebranding" a Nougat phone "I thought" I was on topic.

I apologize if I wasn't

I will ask elsewhere about finding a proper TWRP for my ROM, if this is not the right 3D.

Thank you very much for the help you gave me so far.

You did it right.

Your idea of staying on LOS and flashing Images is nice, but not practicable.

Note: The Firmware Update is a complex and not only stored in vendor and so on. It is the summary of all parts, even such, which are not flashable with Fastboot Mode.

[Huawei P9 Plus Guides, News, & Discussion] n206:
I was about to get rid of my P9 Plus Vie-L09c432b387, but I found the fantastic rebrand-update method by Tecalote:). Updates are important to me. So it saved me - for a little more while - spending bucks on another phone.

Now I managed to change vie-l09c432 to Vie-AL10C00B528 Oreo. Everithing is fine so far, some basic Huawei apps are missig, I will replace them with another ones, or I can download them later, too.

My questions - things thatmake me some thoughts:

- On all reboots while booting, I get message, the devise is unlocked, not trusted etc... - I chose while rebranding: no root single sim network patch with OTA enabled.

- is my phone now rooted or not? Better would be not.

- I saw on FF VIE-AL10C00B535, not approved yet. I read some comments earlier that using FF is not recommended. Why? - earlier I could only update the nougat using FF, because OTA's came too late, or never.

- In phone manager by optimizing system, never get 100%, Some options can not be reached, On-line caller ID disabled, how to enable it?

- Seraching and finding the phone is disabled, but I can access the menu, no reaction on touch. I am cueless.

- WLAN securtiy Check is disabled, how to enable it, I can't find a way.

Thanks for the help in advance.

Great work regards to Tecalote :good:
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
Hi :)

In Post #2 (after the last step) at the end of this Guide you can find a Link for a zip file for missing Huawei Apps.

The message "Your device can not be trusted..." is normal and you have it whenever the Bootloader is unlocked (on each Android Version).

The Bootloader can not be re-locked, you would loose all necessary settings to have mobile network and NFC or/and Dual-SIM on rebranded" AL10"

If you have OTA enabled you will receive for sure the next approved Firmware Update.

I told, that there was between b533 and it had extremely Battery drain, that's why it will not come with OTA.

Soon the tests are finished with the new b535 and the status changes to approved, you will receive it.

It's not in every case a advantage to have Firmware installed, before it's approved.

On rebranded Oreo we should be patient and wait for approved Firmware.

I spoke about some posts before yours.

If you can't wait, you can update with HuRUpdater or probably with FF (not tested yet) by your own risk.

But you must probably configure again the network.

With OTA, you must not, because it will stay.

WLan Security Check is a part of TrustSpace and disabled. Online Dialer ID is disabled (because it's for Chinese region)

Your phone isn't rooted, if you did it not manually as described in Post 3.

You're welcome ;)
