Question about EMUI 5.0 update on my EVA-L09

Good day,
I am new on this forum and it been ages i did something to my devices, so concider me complete noob.
I recently got Huawei P9 EVA-L09 version C150 and updated to B183, now, since i got this phone from other country and boot animation is pink T-mobile (despite it's sim unlocked) i automaticly assume it's branded.
Looking up on internet and reddit i found out that majority of P9 already got updated to Nougat (i come from Nexus line of phones) and mine is still on Marshmallow..so tech guy in me feel bad, so bad that i want to manualy upgrade my phone. I've been thinking about it and next logic step is to un-brand my phone, flash global (?) rom and then update it via OTA (or HiSuite app, quite handy one..). Since i am totaly new to it i would like some guide for it.. i've found couple on XDA forums but all for different version of phone, so hence this post.
Also is my ,,logical'' thinking right, or there is some other simple way to do it.. because i really doubt i will get any update. I asked Huawei from my and country where from i got it (Serbia and phone is i think Hungary) all they say it's : ,,it should rool soon via OTA, just wait for it". That was in december..

Used P9 - Missing Stock Apps

Hello everyone!
I just bought an used P9 (EVA-L19) in pristine condition. It arrived with the nougat update but it is missing all Huawei apps. I don't think I really mind not having those (less bloat, hurray!), but I really want at least the camera app! What should I try? This thing is full stock (unrooted), and I'd rather keep it that way... Should I just flash the full stock firmware? HiSuite claims my phone is up to date, but I've got no idea how to check what build my current firmware is.
Thanks!

Oooh... the build seems to be NRD90M "test-keys", which appears to be an old beta build from my googling. Do I have to go back to MM and then upgrade to Nougat? Hopefully I can do all that without a custom recovery...

You have an intermediate firmware.
Search here the B378 for C432 if you want the european version (wich is working fine; some other last updates may have some problems - for example, with B383 me and others have problems with the battery).
Where are you from ??

I'm from Brazil, but I know for a fact this phone isn't brazilian. It comes with a bunch of stuff written in spanish rather than portuguese, and a warranty certificate citing a bunch of spanish-spekaing latin american countries. I'm browsing through the forums and trying to find out what is my Cust yet. But thanks for the response.
Also, if I have to flash something, is it better to stick with Nougat or is Marshmallow more hassle-free?
(I've attached a screenshot of the status screen from Huawei P9 Tool, this is all the data I could gather so far)

I can't read the screenshot ...
On the "About the phone - Version number" what do you have ??
For example, mine has EVA-L19C432B378, where:
-EVA-L19 is the phone model (P9 dual sim);
-C432 is the european version;
-B378 is the firmware version.
Also, you can read that thread too ... https://forum.xda-developers.com/p9/how-to/how-to-downgrade-nrd90m-to-marshmallow-t3541400

All it says on "Version number" is "NRD90M test-keys". I've read that thread, but to downgrade you need a ROM, and without knowing my Cust ID I'm not sure which ROM I should get.
The screenshot shows my serial number (XVV7N16425001010), the model (EVA-L19 - Dual Sim 32GB Rom 3GB RAM) and a weird build string (eng.jenkin.20161230.130431)

Hello,
do you have dual sim , or single sim and NFC ?
Dual sim: EVA-L19 ou L29
Single sim and NFC EVA-L09 (Européan version)

Dual SIM EVA-L19 - No idea if I've got NFC or not. Can't find anything NFC-related on the menus, but it might be that I do not know where to look. Long time Windows Phone user here, just migrated back to Android :laugh:

absynte said:
NFC is an connectivity option.
If you don't have, you have dual sim

It does have dual SIM, and is the EVA-L19. So no NFC then. Does it help? I'm currently looking for debranding guides because I can't find what branding this phone originally had.

Oooh well... so far:
1- *#*#2846579#*#* doesn't work (nothing happens), can't enable Manufacturer mode for DC Unlocker
2- The HUAWEI EMUI site doesn't give me a bootloader unlock code, so can't unlock the bootloader with the official method
So, so far, I can't install TWRP, so I can't flash a C432 oeminfo.bin
Also, the Rollback instructions at https://forum.xda-developers.com/p9/how-to/rollback-eva-l19-android-7-0-emui-5-0-t3496091 fail, as the rollback intermediate firmware just fails at 5% claiming to be incompatible with my device.
Aside from blindly trying to flash random firmwares with the three button method, do you guys have ANY ideas at all? I need a rest, just wasted the whole day trying to get this damned thing fixed
Sad thing: even with a borked firmware install this is still orders of magnitude better than my old Lumia 930.
EDIT: GODDAMMIT, BLUETOOTH ALSO DOESN'T WORK!

I'll give the instructions of the first post a try, though they did not work for the OP.
EDIT: AAAAAND the 800mb file is downloading at 28kbps... this won't be fun

I'm not sure if it would've been better to edit the last post or add a new one, so if this is agains the rules (I've read them and couldn't find it), please inform me and I'll change things accordingly... buuuut.... IT WORKED.
The OP on the topic absynte pointed out never really posted the outcome of his issue and it looked like he never got it to work, so here is what I did:
Flashed the zip file
I flashed the zip file linked in this post through starting up with vol up + vol down + power. Exactly like the guy over there it did not solve my issue, but did uncover I had exactly the same build as him (EVA-L19C185B361 - Middle East / Asia)
Flashed the intermediate firmware
I download the correct intermediate firmware (C185B300) from here and flashed the same way. The *#*#... menu did not work (as in the menu itself didn't show up)
Flashed a MM build
I downloaded and flashed C185B180 for whatever reason (could've gone with tha latest MM build right away AFAIK). Worked great, all stock apps were there and so was bluetooth
Let the phone update itself through OTA
It updated itself to B210 (or B220, don't remember well) and then B385. Seems to be working fine, but I haven't given the battery a fair chance (constantly flashing and updating stuff) to judge its performance.
Thanks everyone for the help!

Rebranding P10 with EMUI 8?

So, to get EMUI 8 I had to rebrand my device to L29C636, and it worked fine until B361 , the last two updates (364 and 365) it refuses to update, if I search with FF it tells me the firmware is not valid for C636, but if I try and check the same firmware with C432 (I believe it was 432, my memory is not great as it used to be) it says everything is cool and I can install it, but for that I need my device to be rebranded again.
I was searching for few hours today, and couldn't find anything useful the last version of HWOTA is a year old and does not support EMUI 8, I did managed to get up to date twrp but HWOTA I have doesn't detects its booted to twrp. Multi-Tool 8 does not support P10 L29.
Security is a great deal for me and a lot of the recent fixes apply for me and it's really getting frustrating that every single important update I need to break my head to install it.
Does anyone have up to date guide for this device? I think my next step will be to check how it handle a meeting with the wall at high velocity...really getting annoyed with this Android sh*t.

Maybe you should roll back to Nougat, rebrand and then update to Oreo...

Can't Update System Software

I just got brand new Xperia X Performance that came with 6.0.1, and I'm trying to figure out why I can update it. It's unlocked but not rooted, basically right from the factory as far as I know.
When I go into Software Update in the phone's settings, it says "Your device already has the latest available system updates."
When I use the Sony app on my PC it says my system software is up to date.
I actually can't find anything about this issue, anybody here have any ideas?
Thanks!

try downloading and running xperifirm, find out if your region has the update at all, you should be able to update atleast to 7 anyway
There are a few variants that are considered as internal units or something like that and they don't get OTA updates, also HK units were stuck on 7 for some reason last time I checked. Mine is a french model, and yesterday I received the april security patches while the global variant got it two months ago

Thanks for the reply.
Here's a screenshot of Xperiafirm. https://ibb.co/dUCN3T
I'm in Canada, though I'm on Freedom Mobile, not Rogers or Bell. I don't think my carrier ever sold this phone, and I'm not sure what would happen if I flashed 8.0 made for Bell or Rogers phones.
Ideally I'd like 7.1.1 Canadian generic for Xperia X Performance, but I can't seem to find that anywhere.
I've also never done this so I don't really know what I'm doing, and don't want to void my warranty!
Thanks for you help!!

Good the ROMs that you see for Canada are all latest 8.0 with May security patches and maybe your phone is one of these and the updates just got stucked for some reason.
First you have to check what kind of model you have to check this, to do so you should open the dialler and type
*#*#7378423#*#*
From the service menu you should select -> Service Info -> Software Info and look for Customization Version:
As I said mine is a french model so it states 1302-9342_R2E your should be something different but only the first 8 numbers matter
then look this number in Xperifirm if yours is everything different from Internal Unit (second column from the screenshot) then there is a easy way to try and update without loosing your warranty
First there is always a risk! But I have done this a few times for my Xperia U and Xperia M5 and had no problems at all.
Do a backup - contacts...everything you need as it will delete them
charge the phone to at least 80%
then you should go to the Xperia Companion and do a software repair, not update but repair
It should install the latest version for your phone but it shows the version it installed only when it's finished...
Even if it has not installed the latest update then just connect the phone to your wifi/LTE and try the OTA updates again (could take up to an hour)
This is the safest way that will not void your warranty in any way but will delete your info (contacts, pics..etc. ) so do a backup prior
And if possible use a laptop with a working battery as even a 1 second glitch in the grid could cause the phone to get bricked
And if your phone is imported from China and the customization number is considered as an Internal Unit the only way you could get 7.0 or 8.0 is by flashing and another ftf file as the ones for Bell Canada or Rogers, there are actually some ROMs uploaded in XperiaBlog
there could be some in XDA but I have not search for any

Thanks so much for the reply...I discovered the version of Android installed on my phone is a version meant for Journalists/Reviewers/Commercial use, and can not be updated. I just got a refund for the 3-year warranty portion of my purchase after pointing this out to them. So after the 90 day warranty that came with it runs out, I'll be able to do anything I feel like with this device.
I'll be looking for a safe way to install 7.1.1 hopefully, and if not then 8.0. There seem to be less issues with 7.1.1, but there's really only one way to find out: when I start using it.
I'll definitely need a point in the right direction when it comes to that though. I understand Sony has an official flashing tool, and you have to unlock the bootloader (which is supported on my phone even with this version). But I haven't done it before and don't know how.

Need to return P9 back to L09C432B504 from c900b300

Hello everyone !
I had a battery drain issue so I wanted to try and change the software before resorting to a battery change, but now my phone is stuck at L09 C900B300 build and it used to be factory L09C432B504. I tried downloading the full package for 501 but the phone does not want to install it as it was "invalid".
Any ideas how I can force the b501 update on the phone ? It's hard to use ADB since the USB-C port on the phone is very worn out and it only maintains data-transfer in a certain position, if it gets shifted even a little bit it breaks the connection.
Thanks in advance !

You did a rollback and you cannot instal Nougat directly back
You must install c432b182 Marshmallow and then let it update by OTAs (with SIM card) to b50x
https://forum.xda-developers.com/showpost.php?p=73131443&postcount=321
Steps 4-9 apply to you (since you are already on c900b300)
---
Don't know what does it mean to you that you changed the software
If you rebranded from c432 to another cust, then you must also rebrand back to c432 by flashing its OEMINFO:

Pls be aware, this is Huawei P9 subforum, not for P9 Lite (different hardware, different firmwares)

Hey !
Thanks for your reply.
I have tried to follow the steps but I need to have the bootloader unlocked and it is discontinued by huawei, and in order to get the code from DC unlocker I need to invest a certain amount of money (id rather hand the phone over to a professional service and pay them and know that I have a fixed phone).
The other issue of the phone is that I cannot open the manufacturer mode on the phone using *#*#2846579#*#* since it does nothing, and I cannot use the calculator since this software does not have a calculator, it doesn't even have a camera app....
So I have contacted huawei support in hopes of getting the bootloader code but I do not hope for too much at this point. What are my other options at this point of handling this on my own ?
Looking forward to your response !

AFAIK, 'certain amount of money' for Bootloader code from DC Unlocker is only 4 Euros
If you search on XDA (various phones, just about Bootloader unlocking) you may find more online services (several months ago I've seen in some post), but they were more expensive
IMO, you don't need unlocked Bootloader if you are just following the first link, for dload-ing c432b182 without flashing oeminfo....

Update:
Okay the b182 package does not require unlocked bootloader which is great, it took the update and started going up all the way to b395 but it stopped there, no further OTA updates... It is okay to use at this point but I'm still curious to know if there is a way to get to it to update to the b50x version. I did try to use the small update for the b501 but the phone declined it.
Still thank you very much for guiding me through this ! This is a huge weight off my shoulders !

In Firmware Finder they have a new method based on eRecovery and changing the DNS server on your local WLAN AP
b50x must be showing as Approved to you for that method
It does not require Bootloader unlocked but no guarantee it would work (I tried with P9 rebranded to AL10 Oreo, managed to change DNS server address, eRecovery connected to but failed to update firmware that way)
There HWOTA method (in few variants) to install FullOTA-MF from Firmware Finder, but unlocked Bootloader is required
https://forum.xda-developers.com/showpost.php?p=75787156&postcount=3
Btw, if you ever unlocked Bootloader on that phone, just use the same code again (one must save always save the code for future needs)
As of recently there are some Huawei service firmware installations available, that also install by dload (not needed to have Bootloader unlocked)

When you download, you will need to unzip
Find Docs and Software subfolders (you may need to untar and unzip Software subfolder again)
In Docs folder there must be Huawei official guide how to install, check if it describes dload method (and what must be un-archived and copied to SD card dload folder from the Software subfloder)
I didn't use it for L09c432 but I successfully unbricked a P9 rebranded to AL10c00 (back to AL10c00 firmware) by such a package, really easy by dload, just by following their HowTo doc from the Docs subfolder
