P9 how update firmware

hi

this is my first post.

I'm very happy i'm here :)

I updated the firmware of an Italian p9, to eliminate the demo retail mode. At the moment the phone has removed the demo mode, but it does not work well, in fact it is not possible to activate the bluethoot, the nfc and the keyboard does not appear to just dictate with google. It does not work even the string * # * # 2846579 # * # * so to try to do the installation of the various firmware downloaded from the previous posts proceed by simultaneously pressing the power button volume + key and volume key - but always tells me installation failed.

Attached the screen of the emui in which the strange thing and the serial number is NRD90M test-keys. Can you please help me to ensure that you can install updated and up-to-date firmware? I'm not very practical, so I ask the courtesy of those who can and will help me to explain the procedure step by step.

thank you very much

After a long time, security updates for P9, EVA L09/L19 c432, c185, maybe some others

Huawei P9 eva-l19 android 7

Hello.

I am new on the forum and i`m asking for your help.

I have an old P9 eva-l19C432B399 and i`m not happy with battery life. I have huge battery drain in idle mode, note that the battery is new. I notice this drain came out with android 7, in android 6 the battery was awsome.

i triend to search some info about rollback package to C900B300 and then to flash stock android 6 C432B1XX but i can`t find any download link for that.

Can you please help me with intructions and links to download the correct versions for my phone.

If it`s any other way to rollback or to improve the battery life please let me know.

Thank you!

I managed to downgrade with dload folder to c432b161, then to b210... But themes are not working. I tryed to go back to android 7 with huawei firmware Finder but no luck.it downloads in erecovery, but after download shows error and it doesnt install. I have no ota updates, updater shows c432b210 latest update. Any ideas?
[Huawei P9 Guides, News, & Discussion] zgfg:
For OTA you must have both the valid SIM and WiFi

For DLOAD, only FullOTA-MF-PV packages are suitable, like on the screenshot

Upon downgrading/upgrading make sure you do Factory reset from (e) Recovery
[Huawei P9 Guides, News, & Discussion] ViorelCrt:
Thank you for your reply.

i have a question. when i am checking the availability by imei, all the PV firmwares are not approved . The first firmware that is approved is B388 and it's an FULL-OTA-MF, none of the above B388 are PV .... i didn't tryed any other firmware from FF. Of course none of the firmwares i tryed worked. It's safe to try the not approved PV firmware?

As an update, at the moment i found and downgraded to dload C432B136 firmware that is working perfectly with themes and magazine unlock.... but i want to go to a stable and battery eficient version of nougat. I started downgrading from B399 that was horible on battery standby (overnight 8h - 20-25% battery usage).....

I also tryed to update with FF DNS -> eRecovery/ hisuite or with phone updater (same B388 or B505 FULL-OTA-MF firmware). Downloaded, but after phone restarts i get a failed error:" Failled checking package, please download again"

When i do FF DNS with eRecovery/hisuite/phone updater do i still have to register PV firmware? I didn't tryed PV's

So please tell me....it's ok to try not approved firmware from FF? Are there other ways to get to Nougat?

What do u mean with valid sim and wifi?.... i am using vodafone sim, phone permanently connected to wifi. Phone is carrer unlocked, works also with orange or other networks.

Thank you
[Huawei P9 Guides, News, & Discussion] zgfg:
I've been using P9 for several years (now no more), went through all kinds of firmwares (stock and custom but only EMUI based custom, not AOSP) and I don't believe in user-stories of terrible battery with Nougat/EMUI 5 Clean the bloatware, tune which apps are really needed to autostart and to run in background, disable autostart and background to other apps and you will have perfect battery life.

If too complicated then go back to the ancient MM :)

Specially I don't believe (never believed when I was using P9) in differences between the Nougat versions in battery consumption. Remove by ADB what is not needed, tune autostart and background apps (search on the Net and XDA about instructions) and you will be ok with battery.

Generally, newer firmwares are better (not for 'battery' but because of new features, improvements and stuff)

But be aware that the battery itself must be already old, hence you cannot compare how that battery worked (with MM) three years ago and how it works nowadays (with Nougat)

Sorry but that's my opinion about rolling back to MM in search for better battery life

Btw, it would have been enough to roll-back to MM b182, I've seen also others who went to older b161 or b134 or something and then had problems, not getting OTA back to Nougat

---

Anyway, b360 is older, if newer versions are "approved', then that older will be also ok. Once on b360, you will hopefully start receiving OTA for the the newer Nougats

Again, a firmware from Firmware Finder which is FullOTA-MF but not PV, cannot be installed by DLOAD - it doesn't help if FF shows that firmware is 'approved'. You can only install it by HWOTA methods (also even if not yet approved) , but HWOTA requires an unlocked bootloader

And it is also well-known that firmwares on FF (generally, not specifically for P9), from around 2017 and newer were no more PV, just FullOTA-MF

But there are other sites (not Firmware Finder) where the so-called System Repair installations (packages for Huawei repair services) can be found or purchased (even up to b504/v505) - and they can be installed by simple DLOAD method, but you first need to decide do you really want to bother installing Nougat (and tuning things to get decent battery usage - it can't make an old battery to become young again) or you think MM was better for your battery - then stay on the latesr MM b182 or b210
[Huawei P9 Guides, News, & Discussion] ViorelCrt:
Thank you again.

Please note that i am new with flashing, so this is the reason i ask so many questions:)) I really apreciate your help

I had P9 4 years ago, after i had P10, then a galaxy S9, now i have a P30.... The p9 with i am playing now is for learning purpose:) . So, i didn't mention, but the battery is replaced by me, it's new.

The reason for going to B136 is that on B182 or B210 themes and magazine unlock didn't worked (probably because de firmware wasn't PV, didn't find any PV B182). Probably other things didn't worked, but only this i noticed.

i understand that if i flash dload methot to PV B360, OTA will start? It's that OK?

the steps are: download from FF B360 PV firmware with PC .... Download will have 2 zip files... Do i have to unzip them and put it in dload, or leave them in zip filles? dload folder has to be in internal storage or SD? (i used only SD card and unzip files in folder) ... after your opinion about MM i realy like to get back to Nougat:))

I will try tonight to flash PV B360 and i will get back to you with the result. Thank you again!
[Huawei P9 Guides, News, & Discussion] ViorelCrt:
Ok, so i tryed to install full ota mf pv B360 and B386, none of them worked - failed at 33% on first package. I put in dload folder only update.app, i also tryed to put all the files in the zip file in dload.

Now i am still on B136 with themes working. Guide me please so i can reach at least B210 with themes working. i didn't found a PV B210 to upgrade via DLOAD, do i still need PV to upgrade via FF with eRecovery or Updater? On FF B210 is only OTA-MF or FULL-OTA-MF, B182 is only OTA-MF

Thank you in advance..... download links for firmware will be great if you can help.
[Huawei P9 Guides, News, & Discussion] ViorelCrt:
Thank ypu for all your support

I managed to get to b506 with everything working:)

Yes, i was on b210 and downgraded to b136 for a reason... Themes and magazine unlock didn't worked... I read some of the threads and after downgrade dload to b136 everything was working properly:).

Then i upgraded to b182 with ff proxy ota-mf, everything working... Then i tryed to go to b378 ff proxy full ota mf and didn't worked... Then with same ff proxy i got to b360, so i saw a patern... And from b360 i got to b506:))....

It's strage that it didn't worked with dload full ota pv, it failed after download, didn't worked with ff dns and erecovery or updater... It's more strage that from b136 to b182 and to b360 was unapproved by ff, but it worked. Ff has two b506 versions, it worked the approved eva-l09 and not the eva-l19 that was unapproved.:))....after update, about phone shows eva l19c432b506....it tooked me a week, lots of researching, but i'm happy with the result

So, for me it worked ff proxy with updater, a mix with unapproved and approved ota mf and full ota mf:)). Or it was just pure luck.

Thank you verry much for helping me, p9 it's an old phone with no support any more and probably few will understand why i did it... I did it because of ambition:) now i'm thinking to rebrand so i get to oreo:)).... I just read some post that is posible... I don't know if is easy... I will pass if it needs custom firmware or other complicated tools...

Hi All

I'm currently on B127 on a Vodafone locked L09 P9 and looking to go to B167...Just wondering if I'm okay to jump straight to it or do I need to upgrade to another version beforehand?

Thanks :)

Hi to All

Can anybody confirm if the double tap to wake is available and screen mirroring via wifi for example with samsung smart TV
[Huawei P9 Guides, News, & Discussion] zukriaksah:
Double tap to wake up not yet available even in nougat. I think you can find MirrorShare in smart assistance.
[Huawei P9 Guides, News, & Discussion] aceclift:
you first need to de-brand your phone like I had to. and then you need to flash the cust c432 file in twrp. after this you then update to B166 which is the latest via the dload method on your phone

de-branding does require you to unlock your phones bootloader (need to get your code first from using dc-unlocker)
[Huawei P9 Guides, News, & Discussion] sheppy1:
Hi

Not sure why you had to do that? I went ahead and flashed B167 via the "hold the power button and volume buttons while booting the phone" method and it went ahead and installed the update without issues. Furthermore the phone is now de-branded too just by me installing the B167 update using the above method...no messing with custom files in TWRP etc.
[Huawei P9 Guides, News, & Discussion] OnimushaPooh:
not need to relock bootloader . just install stock recovery then dload. but you might lost your Root.

unfortunately rooted device can't get OAT
[Huawei P9 Guides, News, & Discussion] Mostar088:
You can do it like that but now your phone is C900 and u want recive any OTA updates.
[Huawei P9 Guides, News, & Discussion] OnimushaPooh:
how can i check my phone is C900 OR what?
[Huawei P9 Guides, News, & Discussion] Mostar088:
Settings - About phone - version.
[Huawei P9 Guides, News, & Discussion] bratfink:
Just a quick little Q... has anyone who's flashed anything comment if they are still able to use Android Pay?

I upgraded from the 166 to 167 version (which I was under the impression is a legit ROM from Huawei... but have since been unable to use Android Pay).

Any info would be much appreciated!
[Huawei P9 Guides, News, & Discussion] vladimir_carlan:
Anyone knows if TWRP and root will work on Nougat? Thanks.
[Huawei P9 Guides, News, & Discussion] sheppy1:
Oh...hahaha. Hmmmm, guess I'll just have to flash them via the dload method from now on then :) any quick way to get it to receive OTAs then or is it not worth the hassle now?

also other than not getting OTAs...does it matter that I have C900 now?
[Huawei P9 Guides, News, & Discussion] OnimushaPooh:
ok, Do you mean "Build number"?
[Huawei P9 Guides, News, & Discussion] Mostar088:
Yes

---------- Post added at 12:29 PM ---------- Previous post was at 12:28 PM ----------

You have no stock themes and Android Pay will not work. Only way to get OTA is to flash oeminfo.
[Huawei P9 Guides, News, & Discussion] OnimushaPooh:
ok, then mine was L19C636B170. so i can still get the OTA update. :D:D thanks
[Huawei P9 Guides, News, & Discussion] sheppy1:
Ahhhh I'll just leave it as is...getting TWRP would need unlocked BL etc. wouldn't it.

Also my android pay still opens etc. and I've just applied some icon themes, backgrounds etc. to my stock Huawei launcher using the theme app and it all worked fine...
[Huawei P9 Guides, News, & Discussion] jphilouxx:
I just would to say that Android 7.0 is just perfect for a beta test version i use it for my daily driver ..screen mirroring is ok with Philips 4k smart tv and all previous settings on last b136 work fine ..camera is better too ..all work on that build...i come from L09c432b136 ...just the same previous question ask before , is that twrp working ? Dont think so ..Just flashed it but cant have it to boot into.. it keep on "device is booting" device start-up screen..keep an eye on good news...:p

How am I supposed to know which download to use from the OP? Here is what I have coming later in the week: https://www.amazon.com/gp/product/B01FEUT68C. I am going to run all OTA updates on it and then what? What do I download?

[Huawei P9 Guides, News, & Discussion] Mostar088:
U have to see when u get it if it is C432, C636, C185..... U see when u start the phone and go to Settings - About phone - Build number.
[Huawei P9 Guides, News, & Discussion] km8j:
But wouldn't the build number change when I update to the latest OTA? Or are you suggesting going direct?
[Huawei P9 Guides, News, & Discussion] Fauert:
Which steps are you doing to flash Android 7, and which rom from where ? [emoji41]
[Huawei P9 Guides, News, & Discussion] Ulver:
The build number will change but the c432, c636, etc number will stay the same and that number dictates what region your phone is from.
[Huawei P9 Guides, News, & Discussion] Mostar088:
U should only update with firmwares with same number, if your phone is C432 u only update with C432 firmware. The last numbers like B166 is the firmware etc.. C is the Cust B is the Build.
[Huawei P9 Guides, News, & Discussion] nisarpari:
I was on b162 but failed to update to Android 7 after getting incompatible error. then i updates with B170 file with dload method... it went well and now trying from B170 version... but still getting same error... :( Mine is L19 model... someone plz suggest a workaround !
[Huawei P9 Guides, News, & Discussion] km8j:
Is this something special with Huawei? Normally build numbers change. So are you saying I can go straight from what is out of the box to 7 with no ota first or anything?
[Huawei P9 Guides, News, & Discussion] Mostar088:
I dont know about 7 because it's still Beta, stick with 6.
[Huawei P9 Guides, News, & Discussion] km8j:
Huh? That's the whole point of this thread, going to nougat
[Huawei P9 Guides, News, & Discussion] Fauert:

[Huawei P9 Guides, News, & Discussion] vibranze:
According to http://rootmygalaxy.net/install-official-android-7-0-nougat-on-huawei-p9-beta/ , there are 2 download for Nougat, one for C9 and another one for L19.

[Huawei P9 Guides, News, & Discussion] nisarpari:
I too think so... L19 people need "EMUI-A168-L19C900B040SP11" file . It would be helpful if any one who already downloaded it can provide a mirror link

Only the UPDATE.APP .. (in dload folder) ?

---------- Post added at 07:22 PM ---------- Previous post was at 07:18 PM ----------

I took the jump to Nougat, it's so fast .. Will see about battery life and report... ?
[Huawei P9 Guides, News, & Discussion] andre1770:
The compressed file is already organized as it contains a dload folder, so you can just extract and flash, but in this dload folder there are many files. In the guide it says to put all the file in dload folder, are you sure that for a downgrade the only UPDATE.APP si enough ? I don't want to brick my phone LoL
[Huawei P9 Guides, News, & Discussion] Mostar088:
U wont brick the phone but u will have the ugly default icons on the phone, that will sort out when u later upgrade to B166.
[Huawei P9 Guides, News, & Discussion] andre1770:
I have one last question if possible, in case of trouble, the warranty will be still valid ?

UPDATE: I just tried with the UPDATE.APP only, same error, once at 50% it says "failed to check the package content. Please download the package again".

U wont break your warranty. If B136 is not working download B166.

Yes that is the problem. Do you know wich cust u had on the phone before upgrade to 7.0?

So I wont be able to install future official update too ? What a ****ty situation...
[Huawei P9 Guides, News, & Discussion] Mostar088:
U must find a full stock C113 firmware or u wont be able to downgrade.
[Huawei P9 Guides, News, & Discussion] andre1770:
But will I be able to upgrade in case of official release ?

First u must find a stock C113 firmware. U wont recive OTA when on C900.
[Huawei P9 Guides, News, & Discussion] andre1770:
This would be a problem, WIND didn't released their firmware, but I'm gonna ask to the assistance.

And what if I will update my phone via dload with the future official release ?

Or maybe I could send my phone to the assistance to get it as I received....

I don't know what to do... someone have some tips ?

Thanks bro.

I found the size of the file is 1.33GB so I believe the file download from the following 2 links are the same with yours.

https://www.hidrive.strato.com/lnk/upFjFlUW

http://downloadmirror.co/29Wg/p3-s15...X58sX8sWynk%3D

I'm still downloading and will compare the MD5 later.

Just to confirm on the installation steps, extracted from your post.

1. After download update.zip please extract it.

2. Create "dload" folder in the root of your SD card.

3. Move "UPDATE.APP" from the update folder in no. 1 to this new dload folder.

4. Go to dialer, type *#*#2846579#*#*

5. Choose SDCard Upgrade.

6. The rest will be done by its own.

7. Cheers!

I'm using fROM Future v3 so do I have to un-root and re-lock the bootloader before I update?

Lastly, is the Nougat ROM pre-rooted or can we use current root method to root it?

Thank you.

Cheers.
[Huawei P9 Guides, News, & Discussion] zukriaksah:
Correct... although p9 is new for me, but normally when we want to "restock" the phone, most of the phone, we need to relock the bootloader and unroot the phone. Anything report here...

Is this for L09 or L19?
