Thx for that guide.

Unfortunatly I'm not able to flash the b361 version (nor B360). I got a "failed to check update package". Everything else went fine.

I'm now in C432B182 with bootloader locked, not rooted.

Any idea ?

Thx

Edit : one of the issue is that when downloaded files are copied to the mobile, the copy failed at some point of time. The files size are really different , near half the size they should be.

So I copied the 2 files (update.zip and update_data_full_hw_eu.zip) to the dload folder, then ran a manual flash, but I still got a "check package failed " :(

Don't know what to do now

Edit 2 : Finally get B378 by using HiCare "Early adopter option" !
[Huawei P9 Guides, News, & Discussion] Z-Blade:
So you went form B182 straight to B378?
[Huawei P9 Guides, News, & Discussion] ah_cleo:
Yes i know abt this. What i meant is that i will follow OP method to unlock bootloader, flash twrp and L19C636 oem info, and reflash a stock L19C636 rom in, it shld be it.

Correct me if i am wrong.
[Huawei P9 Guides, News, & Discussion] Z-Blade:
Technically speaking, it should work but what I have noticed with this phone is that the same method does not work for everyone and I dont know why that is the case. Do give it a try and let us know how it went.
[Huawei P9 Guides, News, & Discussion] orlith:
Yep , exactly
[Huawei P9 Guides, News, & Discussion] Buran79:
Nice!! after a very careful reading of this guide, and understanding what things to do from the linked steps guides... I just got it!!

I debranded my L09 Latin America C25 to the European C432, time consuming indeed but worth it.

One thing I had to do, not as stated in the guide, is that in order to reboot into the TWRP I had to use the SRKToolHuawei-Lod-Chong-V2.0 / Utilities submenu/ reboot to recovery. Because the buttons combination always got me into the Huawei eRecovery. But now in TWRP I flashed the oeminfo c432 zip, factory reset, and wipe dalvik/cache partitions. After this I proceed with the reflashing of the first step firware, factory reset and wipe partitions this time with the Huawei Recovery instaled by the firmware (diferent than the eRecovery) and then after boot I started to receive the MM OTAs, and the last step is to use the Huawei Updater 2.0 to flash the Nougat, and that was all. Even Nougat OTAs works. I'm no beta tester, nor ever did Root.

thanks!
[Huawei P9 Guides, News, & Discussion] Z-Blade:
Cool, interesting to know.
[Huawei P9 Guides, News, & Discussion] belfast1888:
I done the same and had to return the phone to Giffgaff and they repired the phone. Put in a new board I think as the Imei number has changed. I have since learned that you can download rollback package from here ttp://consumer.huawei.com/uk/support/mobile-phones/p9_uk-sup.htm it will get your phone back to being recognised by USB etc
[Huawei P9 Guides, News, & Discussion] Nawor81:
Thanks, I have tried the aussie rollback package without success. Anything I try and flash over the current firmware only gets to about 50% then crashes so I'm at the point of sending it off to be fixed as well. On a side note I got it connected to the pc after mucking around with cables and the only way it would work was through a usb 3.0 port which I didn't think of until last of course
[Huawei P9 Guides, News, & Discussion] haani86:
Did you manage to update it to 182 as I am getting the same issue?
[Huawei P9 Guides, News, & Discussion] twe69:
Nope still on 166, not sure how to progress.
[Huawei P9 Guides, News, & Discussion] haani86:
Is there anyone else having the same issue as us, I have just flashed to 138 again upgraded to 166 then did a wipe/reset still can't see the 182 update via updater?
[Huawei P9 Guides, News, & Discussion] twe69:
Not sure in this thread or another but someone else has the issue and when contacted customer support they said 166 was latest for UK.
[Huawei P9 Guides, News, & Discussion] haani86:
Yeah read that in another thread as well, guess we are stuck on it for now.
[Huawei P9 Guides, News, & Discussion] bcartwright86:
I just manually flashed 182 which you can download from: http://www.carbontesla.com/2016/11/download-huawei-p9-b182-marshmallow-update-europe/

after this was able to carry on the steps and have been on B378 for about a week now love it, so much better
[Huawei P9 Guides, News, & Discussion] twe69:
Hi there, thanks for the reply. It says that you must be on B170. Did you just go from B166 to B182?
[Huawei P9 Guides, News, & Discussion] Z-Blade:
You should be able to flash it to B182 from B166. There may be a chance you will not get the OTA for B378 from B361 and you may need to manually flash B378 if you want it.
[Huawei P9 Guides, News, & Discussion] haani86:
thanks downloaded 182 using firmware finder from the playstore then used the above method to update to 182.

updating to 361 now using the huawei update 2.0 all going well, thanks!
[Huawei P9 Guides, News, & Discussion] twe69:
Good to know. I will attempt the same. Let me know if you had to wipe your data or anything, cheers.
[Huawei P9 Guides, News, & Discussion] haani86:
nope didn't have to wipe or reset phone. Just updated to 182 then 361
[Huawei P9 Guides, News, & Discussion] g0dz1lar:
Thank you!!!!

Z-Blade, thank you SOOO much for the time and effort you put into this "How To"!

--==Short version==--

It has saved my skin as I went from L09C432B136 to L09C432B140 (which bricked the phone as I didn't know what I was doing playing around with Firmware Finder :( ). Then managed to recover to L09C900182 and now I have an awesome Nougat powered P9 running latest (auto updated) L09C432B378... REEESPECT! :)

--==Long version==--

But it wasn't easy...getting the bootloader code was a pain in the a$$ as the Huawei site doesn't work at all... you register and then it takes you to the home page, dead end...

Ended up getting it from dc-unlocker by painfully following the instructions from https://www.dc-unlocker.com/huawei-android-hisilicon-unlock-guide.

The longest part was figuring out how to install the drivers... basically if you see about 4 x "EVA-L09" under Device Manager when you have your phone in "Manufacture Mode" then choose any of them and manually add the 3 required drivers. You will need to:

Update driver -> Browse my computer.. -> Let me pick from a list.. -> Have a disk -> Browse and then select "cdc-acm.inf" driver which is under "Huawei Android phone drivers\Driver\X64" folder.

Then I think you need to click on "show all drivers" -> click on Huawei Corporation in the left hand side box and then find the driver names as in the instructions/screenshot. You will need to do this 2 more times to add the additional relevant drivers. Hope some of that makes sense!

After all that I ended up unlocking the phone for about 4 euros. (Don't pay any more than that as you are are doing something wrong! )

Once TWRP was installed (1st time it didn't work so did it again and it installed OK) I was able to flash the oeminfo file which changed C900 (Android Pay didnt work) to C432 (android Pay did work ;)). From then on I followed the rest of the instructions to get B361 installed via HiSuite/SRK Tool... BUT it failed to install because I forgot to re-flash B186 to lock the bootloader.

After that (3am at this point) I re run HiSuite/SRK Tool and all installed perfectly! Once Nougat fired up I checked for an OTA update and there was one waiting for me which was B378!!!

At the end it was well worth it as this version of Android on the P9 is sweet and I'm loving the split screen functionality... full day of use and there is ~20% battery life left... feels very stable and a major improvement over EMUI 4.

So, a long story with a good ending (for me) thanks to you! Cheers buddy and... once again, thank you!
[Huawei P9 Guides, News, & Discussion] haani86:
Successfully updated to 361 then was prompted to update to 378 now on 378!!
[Huawei P9 Guides, News, & Discussion] bcartwright86:
Yeah I just went from B166 to B182, I also got the OTA from B361 to B378
[Huawei P9 Guides, News, & Discussion] halliday77:
When you say 'wipe partition', to which partition are you referring?

Thanks
[Huawei P9 Guides, News, & Discussion] haani86:
Just turn off your phone then start it up by holding down the vol up and power when you see the huawei logo let go off the power button but keep holding the vol up button

This will take you to recovery, wipe partition there and factory reset your phone.
[Huawei P9 Guides, News, & Discussion] halliday77:
Yes, thanks. But which partitions, exactly?

Just the defaults - Data, cache and dalvik?

Thanks.
[Huawei P9 Guides, News, & Discussion] haani86:
There is only one option as it should boot into Huaweis recovery not TWRP.
[Huawei P9 Guides, News, & Discussion] Kiusugi:
Hi at all,

I've got a big problem with unlock code. When I go on the site and i search my P9 I kickback to the login page and when I try to click on "Unloack Code" link I've got the same thing. There is a link, official, where I get this code?
[Huawei P9 Guides, News, & Discussion] bcartwright86:
Do you mean bootloader code?

http://www.emui.com/en/plugin/hwdownload/download
[Huawei P9 Guides, News, & Discussion] twe69:
Am now on the latest Nougat build to :)
[Huawei P9 Guides, News, & Discussion] Z-Blade:
Thank you for this, I have updated the guide to include this if a factory reset did not help.
[Huawei P9 Guides, News, & Discussion] smithal_uk:
Hi There, Just wanted to take the time to say a huge thank you. Having bricked my EE branded P9 twice and having had to pay for credits from DC-Phoenix both times to get it booting again with a C900B136 build, I followed your guide to the letter and managed to not only get C432B361, but the OTA updates are now functioning fine and it has auto updated to C432B378!

Incredibly happy user, and I now understand a lot more about the process and what the different flashing methods do etc. Absolutely over the moon.

I have been trying desperately to get Nougat installed for aome time (almost immediately since I received the phone back in July 2016 as it was totally useless at tracking fitness (Endomondo and Strava etc.) kept losing GPS reception / the apps being closed down due to the power management features of EMUI 4.0. I hopes EMUI 5.0 / Android N will fix this, but it remains to be seen, weather has been crap since.

Just major Kudos to you sir! :) You are in my eyes a P9 expert! I have always had Samsung phones before and they have always seemed a doddle compared to Huawei.
[Huawei P9 Guides, News, & Discussion] Jonestown:
Just to throw this out there, this works on the C706 (New Zealand) variant as well, if anyone here was wondering!

Cheers to our Aussie mates for putting this together.
[Huawei P9 Guides, News, & Discussion] Nawor81:
Well after some tense moments trying to bring my phone back from an unofficial build I finally got it my P9 to upgrade to B361!! And now its doing an OTA for B378!!!!!!!!!!!

Many thanks to Z-Blade for not allowing me to throw my phone against the wall :D Great guide mate.
[Huawei P9 Guides, News, & Discussion] play541:
Hello All, I am new with my P9, mine has got the Telstra branded unit, been researching to get rid of this glad to find this link.

My questions, after doing this debranding:

1. bootloaler will be relocked ?

2. Phone is rooted.?

3. Runs on official EMUI ROM?

4. will get future OTA update?

and you mentioned 'Make sure you have the stock recovery already flashed' sorry I don't get it, thought current recovery is stock, should I reflash with stock recovery?

Many thanks
[Huawei P9 Guides, News, & Discussion] TG09:
Got it all working now, yay.

Thank you all involved

Only thing that is annoying, there is no Sync tile to turn off or on.
[Huawei P9 Guides, News, & Discussion] Nawor81:
1. I'm pretty sure the bootloader is locked again

2. Phone isn't rooted at all

3/4. 100% official, even get OTA updates at the end.

I think the mention of stock recovery is advising that you shouldn't have TWRP installed. It's likely you'll lose the Telstra warranty (Mine was Vodafone so thats gone) though I don't know if Huawei would find any issues for them not to honor the warranty if something arose after the installation is complete?

---------- Post added at 10:36 AM ---------- Previous post was at 10:32 AM ----------

There are quite a few apps that can add tiles now though I know the frustration! I just want some lockscreen notifications to stay on the damn lockscreen, not disappear once the phone is unlocked... Netflix, Plex, any media really should stay on the lockscreen, but alas, I would need to use NiLs to manage that problem and its never as fluid as the built in option.

[MENTION=8058469]Nawor81[/MENTION]

Understood., Thank you!:good:
[Huawei P9 Guides, News, & Discussion] TG09:
I know what you mean i use Yatse and Doubletwist and they are not on the lockscreen, annoying.

Can you name any apps that can add tiles, and I will take a look.

Cheers
[Huawei P9 Guides, News, & Discussion] Viper888899:
Finally decided to bite the bullet and update my Vodafone branded version from B135 to B378. followed the guide, only got stuck at installing TWRP, once i enabled OEM unlock that got me through.

Thanks for guide!
[Huawei P9 Guides, News, & Discussion] Dre1300:
This is SOOO confusing for me, or i'm just stupid, i have a Huawei P9 EVA-L09, i have only had one OTA update for this phone and really wanted the new Android 7 update, i have updated manually to C900B182 but have heard that this is a cross-over or something and that i wont be able to get any OTA if i stay on this. My question is how do i upgrade to Nouget now. I don't really understand this whole De-branding type thing becuase i have bought my Huawei P9 off Ebay Unlocked so it ain't locked to any carrier, i also live in the U.S.A so something like Vodafone doesn't exist here. Please somebody help!
[Huawei P9 Guides, News, & Discussion] TG09:
I get what you mean, mine was not branded to Vodafone here in NZ. I went and did it anyway, so far so good.
[Huawei P9 Guides, News, & Discussion] Dre1300:
So you have followed the steps on this article and have Nouget now? Well looks like i will do that then, are there any steps i can skip, and can i go back to a C432 build from C900 by just simply flashing C432.
[Huawei P9 Guides, News, & Discussion] sch47:
I have the same problem if someone is kindly and want to help me and this guy please reply i tried everything and now im ended whit this version " eva-l09c900b182" and the original one was eva-l09c440b168 I'm not good at coding ori things like that just wanted to have android 7.0 because i have some issue whit this phone f**k huawei consumers care . Please help me whit that
[Huawei P9 Guides, News, & Discussion] TG09:
All I can say is carefully read the steps and follow the links. I did and it worked fine, only thing is when using the SDK bit, you might need to unplug and plug the connection between your phone and pc a few things for it to pick up.
[Huawei P9 Guides, News, & Discussion] sch47:
how can i get huawei updater?
[Huawei P9 Guides, News, & Discussion] Dre1300:
Well i guess i will follow these steps even though i don't have to De-Brand my phone because it's not locked to any carrier. I hope this works, love this phone but the software is all screwed up, we should have to manually update our phones and wait so long for a major update.
[Huawei P9 Guides, News, & Discussion] TG09:
My phone wasnt branded to any carrier, these steps worked for me.
[Huawei P9 Guides, News, & Discussion] sch47:
i have a new problem now i can't download the bootloader code from huawei website , it doesn't work i mean i can't find the p9 online p8 or older version , it is universal or something or anyone have this problem berfore
[Huawei P9 Guides, News, & Discussion] Z-Blade:
If you are on the C900B182 firmware, this means you have skipped a step (or 2 or 3), Re-read step 2, 3 and 4.

Step 1 will get you onto the C900B136 firmware, you then need to flash the C432 oeminfo (step 2 and 3) via TWRP. After this, you need to flash the C432B136 firmware again (step 4) via the dload method. After this you do a factory reset and then you should be on the C432B136 firmware.

You dont need to go and find the P9 page. If you go to http://www.emui.com/en/plugin/hwdownload/download, you can find the Unlock Bootloader link under the search bar.
[Huawei P9 Guides, News, & Discussion] Nawor81:
Well I have to back pedal a bit. After playing around with various apps over the weekend it does seem that Netflix media notification stays on the lockscreen and Google Play music will be embedded in the lockscreen when music is playing. So it looks like they have improved some things.
[Huawei P9 Guides, News, & Discussion] Dre1300:
HELP! okay so i got to where you have to enter the bootloader code, i enter the bootloader code in the SRK tool but nothing happens, it just says waiting for device...... i do now have C900B136
[Huawei P9 Guides, News, & Discussion] Dre1300:
Okay so i have now gotten to the part where you have to flash oeminfo-huawei-p9-eval09-c432.zip, how do i do that, this disk file i cant find anywhere on TWRP...
[Huawei P9 Guides, News, & Discussion] twe69:
Spotify not appearing either, getting slightly annoyed with that lol! Luckily am using my smart watch to control it.
[Huawei P9 Guides, News, & Discussion] Nawor81:
If I recall correctly just have it saved somewhere on the phone or SD then navigate through TWRP to find it.

---------- Post added at 10:35 AM ---------- Previous post was at 10:30 AM ----------

I'll ask the basic question, you have the notification settings for that app correct? I don't use that app so couldn't offer more advise though I did see some issues when googling the lockscreen problem. I just searched 'huawei lockscreen notification spotify' and there are a few forums which may lead you in the right direction?
[Huawei P9 Guides, News, & Discussion] Dre1300:
Okay so after doing all of this, i flash the oeminfo-huawei-p9-eval09-c432.zip and then power phone off then i flash the C900B136 via the dload method right or should it be the C432B136 firmware? i still am on the C900B136 which looks like an old KitKat home screen, really odd. what am i doing wrong.
[Huawei P9 Guides, News, & Discussion] twe69:
Sorted it thanks. Got a bit lazy I guess!

Basically.... Settings > Notifications & Status Bar > Notifications Management

Then go to each individual app and enable 'Display on the lock screen'.

All of mine seem to be switched off by default. have enabled it for several apps now.
[Huawei P9 Guides, News, & Discussion] Pombal81:
[/COLOR]Hi there - which App did you use?
[Huawei P9 Guides, News, & Discussion] Nawor81:
I just discovered an app called 'shortcutter' which had the sync told, amongst others. Available in the Play store.
[Huawei P9 Guides, News, & Discussion] Z-Blade:
I am not sure what you are doing wrong, I would suggest that you go back to square 1 and start over again. A quick summary:

1. Flash L09C432B136

2. Unlock bootloader and install TWRP

3. Flash C432 oeminfo

4. Flash L09C432B136 again

5. Update to B182

6. Update to B361
[Huawei P9 Guides, News, & Discussion] Dre1300:
Z-Blade, when i flash the L09C432B136 a second time after flashing oem file via TWRP, it fails, why is that? my bootloader is unlocked.
[Huawei P9 Guides, News, & Discussion] Z-Blade:
Just to double check, you unzipped the L09C432B136 firmware and placed the dload file onto your sdcard? You might want to redownload the L09C432B136 zip file again in case something happen to the original copy or you can try deleting the dload from the sdcard and put it back in again. The other thing you can try is to wipe cache and do a factory reset (can do this via twrp but make sure you do a factory reset and not a full wipe). And just to cover everything, you are powering on your P9 by holding volume up & volume down & power button?

EDIT: Another thing you can try is flash the oeminfo again via TWRP.
[Huawei P9 Guides, News, & Discussion] tooly2601:
Can i go directly to 361 from 182 or first to 360?
[Huawei P9 Guides, News, & Discussion] Z-Blade:
Follow the guide. :D

But to answer your question, you go directly to B361 from B182 (like it says so in the guide).
[Huawei P9 Guides, News, & Discussion] xtcislove:
Hello thank you im on EVA-L09C432B378 now and everything is working except from root etc.

I cant flash any recovery (Command not allowed)

FRP is locked and i cant select it in developer settings because its greyed out

Bootloader is unlocked

No command is working in fastboot everytime it tell me not allowed.

Can someone help?

Edit: Sorted

Watch out:

DISABLE OEM unlock BEFORE updating to nougat B361
[Huawei P9 Guides, News, & Discussion] ah_cleo:
quick update.. i was previously lazy but i did the required stuff finally..

as i flash to nougat previously alr so i have to roll back and downgrade it to andriod 6.0. i used L19c636168 stock rom. so when i was back to MM, i re do how OP actually mentioned except that after install twrp, i went on to root and using the SRK tool, under utility, there is a option to change the oem info.. from there on, once it is done.. every thing back to normal.. after changing the oem info, i jus flash again l19c636168 and it relock bootloader, stock recovery and unroot the phone..

now i got a c636168 instead.. however from there onwards, if to upgrade to nougat, i use firmware finder to upgrade to higher version

Prep Work

- Backup all your data because your phone will get wiped.

Hi Guys

dumb question:

does it wipe just the internal memory or both the external SD card as well?

thanks
[Huawei P9 Guides, News, & Discussion] tmohammad:
Also does it invalidate the warranty as you have messed with the firmware?
[Huawei P9 Guides, News, & Discussion] benjamen50:
If the bootloader is unlocked assume the warranty is void.
[Huawei P9 Guides, News, & Discussion] Z-Blade:
It does not wipe the external sd card. So you can back everything up to your SD card if you have enough storage on it.
[Huawei P9 Guides, News, & Discussion] play541:
Thank you Sir! all clear and ready to go.
[Huawei P9 Guides, News, & Discussion] Z-Blade:
There is a reason why I put in the guide that you should read through the whole guide before attempting it and I dont mean glancing through it. There is a lot to do, its time consuming, can be confusing and every step is necessary. If you read the part where I wrote NOTE: When you flash this firmware again, it will lock your bootloader (Fastboot will tell you that the phone is unlocked but I assure you, your bootloader is locked) and restore to stock recovery. You would of saved yourself hours of messing around.

Lastly, nothing in the guide mention anything about an OTA to Nougat, re-read steps 6 and hopefully you wont hit anymore issues.

EDIT: Just saw your update. Glad you were able to get there in the end. I pretty much went through the same thing at the very start, the whole point of me putting together this guide was to give people a clearer path without the stress, lack of sleep, time wasted and mild heart attacks that you might have bricked your phone.
[Huawei P9 Guides, News, & Discussion] lostunsunghero:
Yeh totally nothing to do with you and everything to do with me. It was a combination of me wanting to do it as fast as possible and being sleep deprived. I thought given my background in other phones this would be a walk in the park.

Best advice I can give to anyone trying this is to read your guide then read it again and then when you think you have understood it read it one more ****ing time lol. Funny thing is there wasn;t any particular reason for my rush, I bought this phone 5 months ago and only just turned it on today for the first time.
[Huawei P9 Guides, News, & Discussion] melissmi:
I've managed to get on to nougat (emui 5.0) using these instructions. Thank you!

I'm still getting the yellow warning screen that lostunsunghero mentioned. I tried to 'relock' using SRK tool but that failed. Any tips/tricks?
