I'll receive my p9 in this week!

But my brother, with a vodafone p9, has b133 as the last update.

It's possible to debrand the phone, but u will void your warranty just so u know.

How do I backup oeminfo and custom?

Could you please help me through the procedure of changing my phone to C432 so that I can update to latest official C432 update?

Hi,

I have just one question for debrand. I have vodafone rom (C02). I have to unlock bootloader,install twrp,root,change oeminfo and custom.bin, then stock recovery > dload firmware c432.

After this procedure, will I have bootlooder unlocked or locked? Will I receive OTA? App 'themes' working??

Thank you
[Huawei P9 Guides, News, & Discussion] thess:
locked and you can ota update

Will this work for my p9 EVA-L09C45B140?
[Huawei P9 Guides, News, & Discussion] hpsauce37:
I have done the above and am now on c432 but now my themes etc don't work and I have a red warning message when I start up the device.

Is that because I need to re lock bootloader? If so how do I do it?
[Huawei P9 Guides, News, & Discussion] hfmls:
same, any advice? i can't even install twrp again :|
[Huawei P9 Guides, News, & Discussion] hanniSK:
If you have a red warning message when I start up the device, you must unlock bootloader again. Than you will have orange warning message.
[Huawei P9 Guides, News, & Discussion] hfmls:
But it says bootloader unlocked
[Huawei P9 Guides, News, & Discussion] hfmls:
ok had to hard flash version again, don't know what happened, had to unlock bootloader again, install twrp, and root.
[Huawei P9 Guides, News, & Discussion] hpsauce37:
Anyone?

Surly if I have done all this with the view of debranding my phone and installing generic 432 firmware so i can get all the updates etc I should not have to root again.

Am I missing something or not completed the process?

---------- Post added at 09:56 PM ---------- Previous post was at 09:54 PM ----------

This is effectively what i have done but now my themes don't work and I have the red warning message when I start the device about device being untrusted or unsafe.
[Huawei P9 Guides, News, & Discussion] hpsauce37:
Anyone?
[Huawei P9 Guides, News, & Discussion] Atarii:
Install Paul O'Brien's B136 package from here: http://xdaforums.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818 via dload method, then OTA update to the latest. This will get you on 432 properly (stock recovery, themes working etc.)
[Huawei P9 Guides, News, & Discussion] hpsauce37:
Thanks

Will this wipe the phone again going from 432 to 136? How does this then put me back on 432?

Will this also get rid of this red warning I get on start up?

Sorry for all the questions
[Huawei P9 Guides, News, & Discussion] Atarii:
Yes it'll wipe it.

It's still the 432 Europe variant; the full version is EVA-L09C432B136. Once installed, you can then use the Update app to go to EVA-L09C432B166 (or above).

This will get rid of the red bootloader warning (it restores stock recovery) and get you on track for the upcoming Nougat beta build.
[Huawei P9 Guides, News, & Discussion] hpsauce37:
Great

Giving it a go now. Thanks for your help
[Huawei P9 Guides, News, & Discussion] hpsauce37:
I've downloaded the file via the mega link and moved the file to dload. It does not say update.app or anything like that but instead is named something else. Is this correct or does it need changing or something?
[Huawei P9 Guides, News, & Discussion] Atarii:
Extract the dload-huawei-p9-eval09-eva-b136.zip and it'll have a dload with:

dt​

hw​

UPDATE.APP​
[Huawei P9 Guides, News, & Discussion] hpsauce37:
The file downloaded via the mega link was something like 2.3gig but had a different name. No option to extract anything.

I'm a bit confused, sorry

---------- Post added at 11:19 PM ---------- Previous post was at 11:16 PM ----------

It's named .getxfer.28384.0mega?
[Huawei P9 Guides, News, & Discussion] Atarii:
The MEGA link is fine here:

.

Just download that zip file and extract to sdcard. It'll contain a dload folder
[Huawei P9 Guides, News, & Discussion] hpsauce37:
OK I'll give that a go.

So when I have done this and got the phone back up and running I will them be able to get the latest updates which I assume is 182?

Will it just offer me this, I mean I don't need to download anything else and do the same process again.
[Huawei P9 Guides, News, & Discussion] hpsauce37:
This is what I have when I extract the zip but there is nothing in the folders?
[Huawei P9 Guides, News, & Discussion] Mostar088:
Download to pc first then extract and put in the dload folder in the phone
[Huawei P9 Guides, News, & Discussion] hpsauce37:
OK so i have downloaded the file twice now and what happens is when I select to extract the file it gives a message saying extraction error.

Surly though the file must already be extracted as its 2.4gb?

How should the extracted file and folder look in the dload folder before I flash? Does the file I have above just need to be renamed? Is it because I'm on 432-180 at the moment it will not go back to this lower version or is it something to do with the red warning message on start up?
[Huawei P9 Guides, News, & Discussion] Atarii:
Your download is corrupted. Try downloading a different way like Mostar088 said

Hello dear developers...Recently I bought a used Huawei p9 lite vns-l21c150b106 single sim...It is cosmote branded and I want to debrand it cause I found out by searching that there are several updates such as b150...When I try to update my phone it says that has the latest updates...I wanted to ask if there is a way to debrand it and return to official Europe stock rom without void my warranty...I found a way in the internet through local update via sd card but I don't find the stock rom Europe(I live in Greece)for my single sim vns-l21...I found only vns-l21c432b160 which is for dual sim...I think that vns-l21c150b160 must be for my single device,i suppose that the difference is c150 and c432...any solution please??? Also the only way to debrand does require unlock bootloader and root???I don't want to void my warranty...
[Huawei P9 Guides, News, & Discussion] Z-Blade:
Hello, this is more of a Q&A but I just got a free Huawei P9 yesterday and I am having a look to see what development options there are. This is probably a noob question but what is "debranding" exactly? I read through all of the pages and it seems that its pretty much used to allow you to flash different version of the OS that was not specifically used for your country, am I right to assume this?
[Huawei P9 Guides, News, & Discussion] Johnysman21:
My phone is branded...that means when I open or close my device shows up a cosmote logo...the firmware is customized by cosmote and I cant get any updates thus I am stuck to B106...For that so I want to debrand it and return to official Europe stock rom...But I don't want to unlock bootloader neither root my phone...build number is vns-l21c150b106...should normal flash with the dialer-sd update work for my case or I will brick my phone???

[Huawei P9 Guides, News, & Discussion] voyager_s:
I'm in exact same situation. I have a P9 EVA-L09GBRC555B160. clearly not the latest update. Branded device to 3 UK. I am not looking to root or unlock the bootloader. Surely there must be a way to manually update official stock roms no? Is debrand really required?
[Huawei P9 Guides, News, & Discussion] voyager_s:
I've given up on the p9 for now. Returned back to my s7. The p9 is a very well designed device. Not keen on the branded UI though. I've used emui before on my honor 7. It's not all bad. Just not keen on waiting for updates when they are already available, due to carrier branding. Happy Christmas everyone. :) And a happy new year.
[Huawei P9 Guides, News, & Discussion] tom99845:
hi guys, my best compliments for the tool, is great!

but i write also for a little problem, when i try to change the oeminfo and custom.bin of my p9 plus (al10 chinese version) the tool stops at the point of backup of the old settings. the phone is unlocked, with twrp recovery and rooted. what can i do? i select the 4th option to convert in the asia version l29c636.

thank you very much
[Huawei P9 Guides, News, & Discussion] salim0010:

Just changed oem info etc after root and now when i boot the device i get a red logo and it will then say password to decrypt storage..... No idea how to fix that.?
[Huawei P9 Guides, News, & Discussion] master':
enter any word twice time then your phone gone to factory reset.
[Huawei P9 Guides, News, & Discussion] clewis1994:

Does the rebrand avoid the warranty?
[Huawei P9 Guides, News, & Discussion] Craig_D:
Could a kind soul point me in the right direction please?

I have a P9 EVA-L09 running C440B138 on the UK, EE network (It doesn't seem to be branded as there is no EE splash screen at power on/off and no EE bloatware but I may be wrong. I have no other nano SIM to check). I'd like to be able to take the latest updates of firmware but I'm a little confused with the different methods etc. I'm looking for the simplest method to do so, without installing TWRP or Rooting the phone (if possible), if I have to do these things then so be it, but, is it possible just to get onto the latest firmware without TWRP/ROOT? I have a bootloader unlock code from Huawei.

Any help would be greatly appreciated, Thanks.
[Huawei P9 Guides, News, & Discussion] Clewis94:
I'm on the same network, yeah you are branded. If you open the browser the homepage should be ee? ee don't put bloat on there phone anymore but still put there custom OS on. You have to root etc. Basically what you need to do is unlock bootloader, install twrp, root and then follow the first half of the video in the first post but obviously use the p9 options.

You also might get a message appear saying password to decrypt storage just enter it wrong 3 times then a reset button will appear, that's normal just click it :).
[Huawei P9 Guides, News, & Discussion] Craig_D:
I see, I've never opened the browser, only used Chrome. Thanks so much for your help and clearing that up for me. Was hoping to avoid rooting. Will installing C432 replace TWRP with stock recovery and unroot?
[Huawei P9 Guides, News, & Discussion] Clewis94:
Yeah it will. It all takes a bit of time but when u know it all it's not to complicated and if you on a locked device it's pretty much a must, who knows when locked devices will ever get an update.
[Huawei P9 Guides, News, & Discussion] Craig_D:
Thanks for the advice. I got a detailed explanation on how to do it on another thread. I'm not sure I can follow it though and I don't understand terminology and don't want to keep asking questions and be a pain in the arse so I'll just leave it for fear of ****ing up my only phone. Wish I'd known about locked phones from EE prior to ordering. Lesson learned. Thanks again buddy ?
[Huawei P9 Guides, News, & Discussion] Craig_D:
So, here goes with my first likely stupid question......

"........and then follow the first half of the video in the first post........" - where do I follow up to? excuse my ignorance
[Huawei P9 Guides, News, & Discussion] Clewis94:
Until you have done the change OEM info etc command via the tool, after that it will reboot the device. You then need to dload the standard UK firmware.
[Huawei P9 Guides, News, & Discussion] Craig_D:
Do I then use the dload folder install method with the latest C432 firmware? That will then lock the BL/return it to stock recovery/unroot?
[Huawei P9 Guides, News, & Discussion] Clewis94:
Yes that's correct.
[Huawei P9 Guides, News, & Discussion] Craig_D:
Thanks so much for your help mate. That's me on C432B182. Really appreciated :good:
[Huawei P9 Guides, News, & Discussion] Clewis94:
No worries mate! What dload you use? I'm only on 166, cheers.
[Huawei P9 Guides, News, & Discussion] Craig_D:

What is the benefits of debranding?

I have a C185
[Huawei P9 Guides, News, & Discussion] Z-Blade:
You get a stock Huawei boot animation and you get updates sooner since they are pushed directly from Huawei instead of a carrier like Vodaphone.
[Huawei P9 Guides, News, & Discussion] streetsurfer:
Ahh, thanks
[Huawei P9 Guides, News, & Discussion] edmun:
You can always click "Youtube" logo and video will open in Youtube.

As I have now checked this topic, read it carefully, I guess I know all the answers, but just want to summarize.

To perform de-branding, it is a must to wipe the phone completely - True?

When performing a de-brand - we do loose the warranty due to unlocking the bootloader - True? (or is there a way around - which basically would mean - use offline tool to generate bootloader unlock code and lock the bootloader after process?)

Is there any difference based on the "firmware" you are starting with?

Last question - after de-brand and installing newest firmware from Huawei (directly from them), would the phone be "rooted" or not as I would still like to use my bank app and also Android Pay (until I will have enough of it and will enable root again)

Seems that I am on EVA-L09GBRC555B160 which is Great Britain Three network.

Would it mean that I do have C555 base with B160 firmware? (sorry guys.. just recently transferred myself from Nexus 5 where bootloader, recovery, root, flashing is just so much easier).
[Huawei P9 Guides, News, & Discussion] Craig_D:
Yes it's compulsory your phone will be wiped after unlocking the bootloader. It will be locked again when you install official firmware.

Using the tool you can relock. I haven't used this option as I just wanted to debrand and install the latest generic firmware and in doing so locked my bootloader. As my phone came carrier locked, if I was to claim on my warranty, I'm not sure how that would work and I'm now not on locked EE UK firmware, although, I am on official and have never used anything other than official.

To debrand you have to unlock the BL, install TWRP & Root but all of this is reversed when you then install the lastest official firmware.

All of what you are asking was important to myself as I wanted to use my banking app and Android Pay, which I am currently doing.

I came from doing all this on a Note 4 which seemed to be easier when I first started on the P9 but if you have all the tools and know what's required then its actually pretty easy.

Hope that helps.

Hi friend, I'm new comer and using Huawei P9. Version L19C636B320

I tried many times update to B361 version by Huawei updater and Hisuite but unfortunately It didn't work. Follow some guideline I have just download update of L19C432B360 and copy to "dload" folder in my device, using power key and 02 volume button, it has been work and now my device version is: NDR90M test-key.

After that, I have use "update.app" file of some version (L19C636B361, L19C636B190) for change version again but it's not working and when use hisuite said that:

you are using the lastest official version.

Current version: NDR90M test-keys(Official)

Note: I cannot find the "Updater" function in Setting menu too.

So now can I debrand my device to C636? without rooted? (Nougat)

Many thank for help!
[Huawei P9 Guides, News, & Discussion] Mostar088:
U did not flash it the right way, u cant flash C432 on C636, u need to flash it the correct way or u loose some functions and your Build number shows as NDR90M. Use this Rollback to flash back to MM and ugrade the correct way. This is Rollback for L19C636 and it has a pdf guide in it how to flash back to MM.

Thanks for your guide line. My device now unlocked bootloader and I do not have bootloader code.

Please advice how I can get bootloader code before do rollback as instruction (EMUI web does not support at this time)

Or I can rollback with bootloader unlocked.

Many thanks
[Huawei P9 Guides, News, & Discussion] Mostar088:
U dont need to unlock bootloader to rolleback. That is a officiell Rollback from Huawei.
[Huawei P9 Guides, News, & Discussion] Thanggm:
Maybe you misunderstand me. My device was unlocked. And in rollback instruction note that: device is not unlocked or rooted.

So i wonder that where i can get bootloader code or can rollback with bootloader unlocked.

Thanks for help.
[Huawei P9 Guides, News, & Discussion] Mostar088:
Are u sure it's unlocked now? When u flash a Firmware the bootloader gets locked automatic again. Can u check in fastboot if it says locked or unlocked?

Eva-al10c00b377

Hi All

I have EVA-AL10C00B377 (unlocked/Huawei branded) and I would like to convert it to International/European version.

Could someone answer my questions before I'll give it a try please?

1. Do I need to root first? If yes what's the best method.

2. What version of firmware is fully compatible with EVA-AL10C00?

Any advice is much appreciated.

Thanks
[Huawei P9 Guides, News, & Discussion] Z-Blade:
I don't get it... Your bootloader was unlocked... You need a bootloader code to unlock it, so where did you get the code to unlock it in the first place? or did you get this phone 2nd hand and it was unlocked when you got it? Because if you bought it new, the bootloader would be locked and you would need an unlock code to unlock it.

[Huawei P9 Guides, News, & Discussion] SideSkroll:
Hi, I'm here to report a bug (tested it 3 times with the same results)

Trying to unbrand an originally EVA-L09C521B140 to C432.

I can root and install TWRP but as soon as I try to rebrand the phone (when the phone needs to restart) a message on screen that says "phone failed verification, may malfunction" or something along those lines appears and instead of booting to the OS the requires me to enter my decrypt password (which there is none, cause it's a brand new phone)

After that, the only way to "fix" this situation is to enter recovery (TWRP magically dissapears after that error and all that is left there is the erecovery) wipe data and format.

After that I'm able to at least boot the phone, reunlock bootloader, install TWRP and root.

Then, I used this: EVA-L09 OEMINFO CUST432

https://mega.nz/#!Qlwj0JBD!4zs2e-OGtHwvmoruonyE1KlqiXE1R92q2hvVbCXHSfs to flash the oeminfo from TWRP and ONLY THEN was I able to properly install the C432 rom.

This is a big, big issue (specially for other models like lite or plus since I haven't found the oeminfo for those in flashable format.

PLEASE, you need to look into this or someone less knowledgeable/without the need files might wreck their phone (and blame you for it)

unlock/root/recovery install work flawlessly apparently

Thanks for your hard work and for taking the time to read my post [MENTION=4008653]somboons[/MENTION]

**UPDATE** Apparently, this is the solution. Haven't tried it yet. But you should update the OP to include this info:

https://xdaforums.com/showpost.php?p=70518353&postcount=53

**UPDATE2** Nope, no go. Doesn't work. I mean, when I enter 3 times the "wrong" password (3 times, not 2) yes, it does boot up. With a corrupt installation (weird icons etc)locked bootloader and no root obviously (after factory resetting) and if I try to root again (you know, to be able to change the build.ro etc) it locks up again,. So it is basically an infinite loop.

Yes. It is working incorrectly. I can 100% confirm. Please take a look at the issue.

Thanks.
[Huawei P9 Guides, News, & Discussion] Craig_D:
[MENTION=5886741]SideSkroll[/MENTION] hey as for the decrypt password that is normal. It's been a while now since I carried out this procedure but if I remember reading somewhere correctly you just input a wrong password (anything really) and the phone will wipe itself. I'm sorry I can't remember exactly but I did read it somewhere on XDA. I didn't keep an exact tutorial for myself of what I done. Sorry hope this helps you out at least a little.
