I've followed the guide as far as step 5. When I got there, I ended up getting an update for L09C432B166 which installed fine, but I'm not getting the B182 update. Anyone else run into an issue like this?
[Huawei P9 Guides, News, & Discussion] Z-Blade:
No you cant, you need to get to B182 before flashing B361.

Try wiping partition and a factory rest and see if you get the B182 update. If not, you can download the B182 update and flash it via dload but if that does not work, you can try doing it via the Hisuite and Updater method.

Tried on multiple websites and get that error or this one. Why do they make it so hard to update?

Encryption

The guide is great! many thanks!

Apologies if this os not the right place for this.

May I please ask what is the encryption situation with Nougat? I understand that Nougat does not have FDE, is/can the phone be encrypted?

I flashed twrp to root and the internal storage was visible (not zero like when FDE is in place) which was a bit concerning.
[Huawei P9 Guides, News, & Discussion] edmun:
Yep. Had the same. Created new ID as it did not accepted any of my current ones.
[Huawei P9 Guides, News, & Discussion] wards5150:
Got the code by emailing them.:silly: Only just got it so haven't had the time to debrand yet.
[Huawei P9 Guides, News, & Discussion] Z-Blade:
You might want to ask this is the Q&A section. I am not a developer so dont really know too much about the inner working of EMUI.

[Huawei P9 Guides, News, & Discussion] DaavisEs:
Hi, maybe dumb question, but can I skip first step if I already have C900B136?
[Huawei P9 Guides, News, & Discussion] Z-Blade:
No you cant. The firmware C900 means its a cross flash firmware, you need to make sure that you originally flash or had already flash the C432 firmware prior to getting to C900. You may throw a pineapple in the mix if you skip the first step (or any of the steps really).
[Huawei P9 Guides, News, & Discussion] ahhazazi:
Hi guys,

Does it matter what initial firmware your phone have prior to performing step 1?

My phone is from Three Ireland with B150, can I just continue with step 1? Because it would seem like a downgrade from B150 to B136.

Thank you
[Huawei P9 Guides, News, & Discussion] Z-Blade:
The only thing that matters is that you are on a MM firmware, it doesnt matter what carrier you were on. In this case, you need to downgrade to upgrade. :D
[Huawei P9 Guides, News, & Discussion] ahhazazi:
Thank you man. Will start downgrading later.

Cheers!

hi guys,

this might be the post im looking for however, i did post a thread about my problem....

https://xdaforums.com/p9/help/huawei-p9-ota-update-t3598044

i have paid the £8.99 to EE which is my carrier and apparently they need to ask huawei to send me the code to unlock as they dont supply them :/ i need to wait up to 5 days before i get. where do i start? do i need to wait until i get my unlock code and try an over the air update or will i have the same problem.

i did try using firmware finder along with the proxy setting but it upgraded the build number to b142 so not sure what my next step is :(

the last time i tried my mods was on my htc tytn about 10 years ago lol

thanks for help in advance!

This thread is for debranding your P9 and getting it onto EMUI 5.0. I would suggest you wait for someone to give you an answer in the thread you started if you are planning on keeping your P9 branded to your carrier.
[Huawei P9 Guides, News, & Discussion] kakawak:
what if i dont want to keep it branded to carrier? there is nothing branded on the phone that tells me its on EE. i bought it 2nd hand last year and im not sure if it was contract or payg :/

what options do i have and is it worthwhile unlocking my phone from EE at a cost of £8.99??? will this then allow me to continue with custom mods etc...

cheers

cammy
[Huawei P9 Guides, News, & Discussion] Z-Blade:
If you dont want to keep it branded then you can follow this guide. Its completely up to you if you want to unlock your phone or not.

If you are asking questions like 'will this then allow me to continue with custom mods' then I highly suggest you read up more on things like root, custom recovers and custom roms. You dont want to dive into this without knowing what you are getting yourself into.
[Huawei P9 Guides, News, & Discussion] benjamen50:
Bumping this thread just so that new people don't end up bricking their P9's more trying to upgrade directly to nougat without debranding / following these instructions their phone which is VITAL to do to get it working fine on different EVA-L09Cxxx number firmware.

Yes, these instructions are so good that they stop you from soft-bricking your phone badly.

We really need a guide in this sub-forum on how to fix a soft-bricked phone.

- What happens most of the time is that they don't debrand the phone first before going to unbranded firmware which causes signal / network issues and etc.

- Then they downgrade back to older firmware which results in the phone being stuck at the Huawei boot screen (I assume it's the animated red huawei logo one right)?

- Shouldn't a factory reset / wipe data fix that problem? Usually the phone needs to be wiped to get it to boot again when downgrading to an older firmware.

Anyway here's a link for help if anyone's soft-bricked their Huawei P9 after nougat downgrade:

[Huawei P9 Guides, News, & Discussion] kakawak:
appreciate your help benjamin.

I received word from carrier today EE that my phone is unlocked so does this mean i need to pay to get my phone rooted so that i can install custom roms? i would prefer to have the proper p9 nougat installed on my phone but unsure on which version of rom to try etc...

i wouldve thought that having an unlocked phone would make things easier but i guess it doesnt. i also thought i would be able to use firmware finder and download via the proxy to update but it only updated a google fix to version 4.1.3 on emui at a whopping 1.8gb but didnt upgrade to nougat.

is there another option for upgrade or do i have to install a custom rom with certain things not working on my phone ie camera or blutooth???

thanks in advance

[Huawei P9 Guides, News, & Discussion] M..N:
Unlocking the phone from EE is just a network unlock (meaning you can use another networks sim i.e. Three, O2 etc.)

Following the guide in this thread will allow you to debrand your device and install the official 7.0 update from Huawei.

In order to do that you would need to unlock the bootloader which has nothing to do with EE and is done through Huawei (explained in the guide)
[Huawei P9 Guides, News, & Discussion] xLima:
You can unlock bootloader via the Huawei Website where you register, enter IMEI, serial number, model, etc (FREE) or via DC Unlocker (cost 4 EUR), then follow instructions on first post.

---------- Post added at 11:06 PM ---------- Previous post was at 10:11 PM ----------

I would just like to thank you for the post, just tried this on a EVA-L19C605B135, currently running EVA-L09C432B378. So far so good, themes working, WiFi and Mobile Data work, camara is functional.

This is the order I used, initially dload mode and dialer mode would fail to install the firmware. :(

1. Obtained Bootloader unlock key via DC-Unlocker at a cost of 4EUR (I had issues with the IMEI and Serial not matching via the Huawei website FREE)

2. Used SRK Tool to Unlock Bootloader

3. Used SRK Tool to flash TWRP

4. Flashed the C432-OEMINFO via TWRP

5. Used SRK Tool and flashed back to stock recovery

6. Downloaded the extracted the contents of dload-huawei-p9-eval09-eva-b136.zip to the dload folder on the external SD

7. 3 Button dload method the content from the dload-huawei-p9-eval09-eva-b136.zip

8. Booted into home screen with the B136 working

9. Updater had B182 version available for download, downloaded and installed

10. Booted back to home screen and got prompted for the L09C432B378 – 2.27 GB download.

:D
[Huawei P9 Guides, News, & Discussion] kakawak:
hi,

ive unlocked my bootloader with the code given from huawwei. i used the srk mode to unlock it now that ive installed the twrp option and supersu and my device was rooted however i made a boob and installed b136 before i installed c432. is this a problem? what rom do i flash to in order to start again?

ok somehow ive managed to unroot my device when i flashed back to c432. do i flash back to 136? im kinda lost here, do i need tor oot my phone to get update? im not sure how to flash via twrp as it doesnt seem to find the img.

cheers
[Huawei P9 Guides, News, & Discussion] kakawak:
hi guys,

ok i thought i would update this post rather than post several times. all i can say is what a painful experience this was to setup android nougat.....it better be worth it.

i reckon next time i will do some more research before committing to a flagship phone :/

thanks for help

[Huawei P9 Guides, News, & Discussion] benjamen50:
Did your device originally had L09CC432 ROM on it when you got the phone?

If NOT flash the C432 OEMINFO with TWRP as specified on this thread to avoid having issues with Wi-Fi / 3G / 4G / GPS and etc.
[Huawei P9 Guides, News, & Discussion] LordBadHabit:
Valid for non european phones?

Hey guys,

maybe a stupid question:

Is this How-to also valid for non european phones? Or could I expect any disadvantages in Mexico with a C432 build?

My phone is a TelCel branded EVA-L09 with Build L09C69B110 and I really would like to update to Android 7 as with my current build Android Auto is not working (known issue), but waiting on TelCel is a bit like waiting on Jesus...

Thanks in advance and Saludos!
[Huawei P9 Guides, News, & Discussion] Z-Blade:
Yes, you can use this guide to debrand any version of the EVA-L09. You wouldnt notice any difference and all features should be working without an issue (including Android Pay).
[Huawei P9 Guides, News, & Discussion] LordBadHabit:
Hi again, thanks for your guide, worked like a charm.

Just 2 comments:

1. There´s a more recent version of SRK Tool and a video especially for the P9: https://youtu.be/XtJunntjL5A

2. After updating to B182 I was directly offered updating to B378 via OTA, no the last step may be no longer necessary?

Again, many thanks, great work:good:
[Huawei P9 Guides, News, & Discussion] Z-Blade:
It was a while ago when I put up that guide. Huawei might have allowed OTA directly to EMUI 5.0 after jumping on B182. There is also the possibility that you are simply lucky, the flashing processes is not exactly the same for everyone (for some weird reason).

Telstra EVA-L09 C451B130

Hello,

I've just got my P9 ( EVA-L09) two days ago. It seems to have come from Australia, as it has the Telstra branding in boot logo. The Current Firmware I have is EVA-L09 C451B130. I want to know if I can follow this guide to unbrand the phone and get the latest updates?

Thanks in advance

Best Regards

German
[Huawei P9 Guides, News, & Discussion] benjamen50:
Yep. Applies to every EVA-L09 phone. Debranding to C432 cust / oeminfo is what allows c432 firmware to work on the phone properly.
[Huawei P9 Guides, News, & Discussion] andre1770:
I've successfully unlocked bootloader and installed TWRP 3.1.0, but it cannot mount /data partition. Is the data partition needed to flash oem info? I wouldn't break the phone....

Could someone clerify please

After installing dload-huawei-p9-eval09-eva-b136.zip I am able to boot phone and everything seems to work fine, except actual mobile network, Wi-Fi works though. I never dealt with P9 in the past. Is it a normal and I need to proceed further or something is not right? I live in Australia and currently have EVA-L09C34B140 firmware.

[Huawei P9 Guides, News, & Discussion] Tribal123:
This last step number 6 is really needed or the phone will find himself the latest firmware available?

I assume that this guide is to have the phone with C432 in order to have access to European no-branded OTA updates, or not?

thanks...
[Huawei P9 Guides, News, & Discussion] Tribal123:
So i follow all the guide and i've succesfully updated mine P9 L09 to B182 firmware only by OTA. Cust C432..

Now the updater can't find any other version OTA, shouldn't find the Nougat versions B36X or something else?

the only way is to flash by Huawei Updater on PC?
[Huawei P9 Guides, News, & Discussion] benjamen50:
Huawei Updater method is probably the best way to do it:

https://xdaforums.com/showpost.php?p=70594380&postcount=2
[Huawei P9 Guides, News, & Discussion] Tribal123:
Just curious...:angel:

why the OTA Updater doesn't find anything?

I guess the device is now completely de-brand (the CUST is C432 and the phone has been OTA updated itself to B182 firmware..) so Nougat should not been found by OTA updater? (probably i'm losing something:o)

Thanks for the guide, however :good::good:
[Huawei P9 Guides, News, & Discussion] Tribal123:

I have the same problem. I dont get an OTA update to Nougat.

I did everything in this guide and am running EVA-L09C432B182.

What did you do to get an OTA update?

I also tried to update to Nougat B360 via dload, but it always stops at 37%.

Hope anyone can help me to get an OTA update ;)

[Huawei P9 Guides, News, & Discussion] Z-Blade:
If you done everything in the guide, you should be on B361. There is nothing in the guide that tells you to flash B360 via dload. If you get OTA to Nougat, consider yourself lucky because there is a lot of people around the world who is still waiting for it to be pushed through. Most people has forced it onto their phone via dload or Huawei Updater.
[Huawei P9 Guides, News, & Discussion] exibo:
Hey Hey I did something wrong while manually updating with the huawei updater. Now everything is working fine.

Thanks to you all for all the information and guides
[Huawei P9 Guides, News, & Discussion] benjamen50:
I honestly have no idea why OTA updates don't appear sometimes, it's like 50/50 for all C432 firmware users. Some get it and some just don't sometimes it takes time, sometimes it's probably never going to show up on OTA updater and people end up manually updating to newer build like B383 like I did.

I think we all have to wait for official release under OTA to see it appear in the EMUI Updater app.
[Huawei P9 Guides, News, & Discussion] Tribal123:
It seems that Huawei pushes their OTA updates following IMEI serials numbers...

That's why it may occur some time to wait in order to achieve the OTA update..

I flashed the B136 via dload, so step 1 has completed. Upon trying to unlock the bootloader I realised I had deleted the bootloader unlock code from my pc by accident. So I tried to get another one but my phone doesn't have a serial number or imei anymore! I cant get into the status menu in settings either.

I cant stay on this firmware because cellular reception isn't working, and my phone can't make calls or texts. Please Help!

Did a factory reset and wiped the cache and its fine now.
[Huawei P9 Guides, News, & Discussion] thirtybob:
Good day all. Can someone point me in the right direction. After completing the first part of the tutorial my phone is on Build No. EVA-L09C432B181 , which is what it was before. Vendor: HW, Country: EU. Kernel Version and AP Version both state: C900B181 and Parameter Version is CVersionC432. Not a mention of L09C900B136 anywhere. Am I missing something here. I've tried flashing it the dload several times but with the same result. Ant help would be greatly appreciated.
[Huawei P9 Guides, News, & Discussion] zrmughal01:
debranding from c900 to c432

I'm going to try your method, want to clear something 1st. I'm already on a cross flash version l09C900B180 so my question is, is there any need to flash B136 or should I go straight to unlock the bootloader.
[Huawei P9 Guides, News, & Discussion] Z-Blade:
It looks like the dload flashing didnt work and it may not work for you because you are already on C432 and technically you would be downgrading. I think it will be best that you try flashing your firmware to B182 and then continue on through to step 6.

I would recommend you flash B136 (step 1), its a good idea to keep this firmware handy because this is also your unbrick firmware as well. This way we know that there is little chance you will encounter any issues since there has been plenty of confirmed cases that this guide works.
[Huawei P9 Guides, News, & Discussion] thirtybob:
Ok, thanks. I'll give that a try and let you know the outcome.

If I wish to root the phone I have to unlock the bootloader again before flashing the root?

Inviato dal mio SM-G935F utilizzando Tapatalk
[Huawei P9 Guides, News, & Discussion] benjamen50:
Bootloader should be still unlocked. It only gets locked if you manually relock it yourself in bootloader / fast boot mode.

Refer to this post I made on which root and TWRP you should use. If the rom build is b380 or higher it will work fine.

You can confirm if bootloader is unlocked under developer options enable OEM unlocking. If it is greyed out and turned on you know the bootloader is unlocked. It doesn't relock also when flashing otas via TWRP recovery.

Does the nougat came with a keyboard switcher on right end of its navigation bar?

I would go through anything to get that feature :3

Can any folk using EMUI 5 on P9 can confirm it exists?

OK, really was hoping my first post to this thread would be a positive one. All fine except the last step - followed the instructions but for some bizarre unknown reason my HiSuite package keeps saying "No Internet Connection. Please check your network settings." With a 'Retry' button at the bottom.

My version of HiSuite doesn't have a 'System update' option, merely 'Update' - I know I'm being a pedant, just confirming this. I've set the proxy and the port address; I've got the following output in Huawei Updater:

p.s. When I remove the proxy information it indicates that I am at the latest firmware (ie there is an internet connection) - as soon as I input the proxy information (no information for user/pwd) it reverts to no internet connection'...thoughts?

p.p.s I have read every word of this thread and the thread giving instructions for the last update three times each and backwards too just in case - there are other people that complained of the same thing but I cannot for the life of me find the answer...please?
