Hi

Have you managed to get OTA yet? I had the exact same problem as you with my EE branded P9. I upgraded to B166 and B182 with the phone updater app but nothing after that. I Used Firmware finder to get to B386 and then B390, then yesterday the phone app update started working again offering me B391 :confused: I updated last night and am now on the most recent build. happy days :):good:
[Huawei P9 Guides, News, & Discussion] nmd87:
Thanks mate, yes I did. I did the same as you in end except the first version I got working in Firmware Finder was B383 (I started with B360 and kept going until I found one that worked). I am now also on B391 but there's a few issues. Favourite contacts cannot be re-ordered and the camera auto rotate sometimes stops working until the phone is rebooted.

Hi

I just got a P9 the other day from Optus. I've never had to flash my phones before; I've always managed to buy unbranded & I've never cared about getting the latest firmware the minute it comes out. Unfortunately, my P9 is Optus branded & the boot animation & chime is ticking me off. So I'd like to unbrand it.

My phone is already on EMUI 5.0 & in a post early on in the thread it was mentioned that rolling back to MM to unbrand causes problems. I've never done this before so I'm not sure how to go about this. Do I follow all your instructions anyway? Do I only do certain steps? Where do I find the stock recovery file?

Any advice for a newbie would be greatly appreciated. Thanks

Hi,

I have an EVA-L09 P9. This was on EE and they had not sent the android 7 OTA, so a month ago, I unlocked the boot loader, installed TWRP etc and tried installing a few roms. I've since used the SRK tool to flash in fast boot and am at build no. EVA-C900B166. I can't relock the boot loader (the SRK tool just hangs). I've tried to use the dload method to install B136, but this fails shortly after starting. I can flash boot using SRK, recovery and system from the B136 dload zip, but although this installs, many things don't work (camera, gallery etc) and the computer has trouble recognising it. I've had to go back to B166 for the time being. I've tried FF to update, but every time this fails.

My wife's phone, same P9, EE, UK model, was 'untouched' and a week ago EE released android 7 which updated no problem...

Does anyone have any suggestions? I would like to get to android 7 by any means possible. Many thanks!

Coming from B123...

PLEASE! Does anybody have an alternative link for the b136 full firmware?

I can't resume downloads from the the mega app.
[Huawei P9 Guides, News, & Discussion] Salty1863:
Hello everyone,

I have attempted to try this method with little success so far, unfortunately I am falling at the first hurdle. I have downloaded the 136 file (2.42gb) and attempted to extract the files but this creates a blank folder with no files inside- can anyone tell me where I am going wrong or is there no file within the download itself?

Thanks
[Huawei P9 Guides, News, & Discussion] benjamen50:
When you extract the 'dload-huawei-p9-eval09-eva-b136' zipped file. There should be a dload folder with contents inside. You copy that to the root to the SD card then you can do the firmware flash as explained by the OP's post.
[Huawei P9 Guides, News, & Discussion] andre1770:
I'm following your guide succesfully, thank you for your contribute.

Just a quick tip: if you get stucked on c432B166, just go on Settings > Updater > Menu > Download latest full package.

It should appear the full version of the B182, so you don't have to install it manually.

EDIT: I'm at the last step. Huawei Updater 2.0 is not working with B361 version, I'm now trying with B360 and it seems to work.

QUESTION: do I have to use Huawei Updater for the next updates? Or will they be automatic? Thanks.
[Huawei P9 Guides, News, & Discussion] benjamen50:
Huawei Updater should work in theory, do not use the latest huawei updater but use the same version linked in the thread as that does not allow proxy bypass to work.
[Huawei P9 Guides, News, & Discussion] andre1770:
It worked fine with B360, but B361 seems to be broker. BTW I updated to B360, then I received B361 directly from system updater. Now I am running B390.

Im using C464B383 Nougat firmware. For debranding (C464 to C432) which procedure i should follow?
[Huawei P9 Guides, News, & Discussion] Patxperia:
Hi, I'm new to Huawei but not to rooting and twrp.

I bought a p9 on Eval-09C432b189 a few weeks ago, and forcing update.app to B210. No further updates possible, I discovered that the phone is not fully debranded. Rootchecker shows root has not been successfully installed, but there are no su binaries in the root folder. Forcing updates showed that the bootloader was unlocked.

Manuf info Eva-l09-vn2

Kernel c900b210

Eva-trunkFASTBOOT

I hope that I can follow this guide with a little more information. The first step, unlock bootloader, has a dead link, and Googling brings me to very risky links.

I want to retain the Huawei warranty so can anyone suggest a guide to return to the original stock, so that I can get updates OTA?

Updated, I received several OTA updates from b210 to b395 today 6/2/18 Nougat is on my phone

Chodzi o to, że chcę się pozbyć brandu T-Mobile i chcę wgrać najnowszy oficjalny NIEBRANDOWANY ROM dla Polski. Mam u siebie ROOT i odblokowany BOOTLOADER. ROOT usunę jak przywrócę ustawienia fabryczne, ale czy mogę zmienić SOFT mając odblokowany BOOTLOADER? Wolę się dopytać wszystkiego zanim sam zacznę robić i coś zepsuję. Z góry dzięki za pomoc!

Oraz czy mogę wgrać STOCK Recovery Androida 6.0 do Androida 7.0? Jeżeli nie to gdzie znajdę link do pobrania STOCK Recovery?

The point is that I want to get rid of the T-Mobile brand and I want to upload the latest official NOT BRANDED ROM for Poland. I have ROOT and unlocked BOOTLOADER. I will remove ROOT as I will restore the factory settings, but can I change SOFT with BOOTLOADER unlocked? I prefer to find out everything before I start to do something and ruin something. Thanks in advance for your help!

And can I upload STOCK Recovery Android 6.0 to Android 7.0? If not where will I find the link to download STOCK Recovery?
[Huawei P9 Guides, News, & Discussion] edmun:
Unfortunately, even if I am from Poland, I would answer in english as this is english forum.

If you have the bootloader code (or unlocked bootloader already) you have to drop the stock dload-huawei-p9-eval09-eva-b136.zip into memory of your phone. In this way, no matter what software you are currently on, you will be reverted back to official, stock old ROM which allows updates to come through.

Changing of the software does include unlocking the bootloader, so if you have done it already, it will not cause any harm. Believe me, it is very hard (and unlikely) to brick the phone if you will follow steps by steps.
[Huawei P9 Guides, News, & Discussion] xxxvego:
Okay, so I can back to b136 if I have UNLOCKER Bootloader, ROOT and not stock Recovery (TWRP)? I just have to follow the step by step tutorial on the first page, right?

I'm on Nougat L09C432B386 but the security patch is from april 2017

Hi, I have followed the following steps to debrand my EVA L09:

Unlocked the bootloader (Succesfully)

Installed TWRP 3.0.2.0 with the ADB drives v1.4.3 (Succesfully)

Then I tried to install a C432B136 ROM but I accidentally pressed the reboot option in the TWRP menu and did not turn off the device, so I could not use the 3 button method to force the installation properly (Power ON+Volumen up+Volumen down)

It ended up being and corrupt installation (Old style icons and theme app not working), with C432 succesfully installed though, vendor info says hw/eu.

So I tried to fix it using the 3 button method to force the installation of the EVA-L09_B136 firmware saved onto the microSD. The system said the the process could not be totally completed, but the icons and the theme app went back to normal. I thought everything work out.

Then I updated to Nougat L09C432B386 throught the OTA application of the phone and everything seemed alright. Only for one thing, the security patch is from april 2017, even older that the one I had before. Is that normal? How can I get a proper installation of Nougat with the latest security updates?

Please, help me! This is my first time doing this kind of things. I am a total noob.
[Huawei P9 Guides, News, & Discussion] zgfg:
Looking to Firmware Finder, b386 was from May 2017, hence it makes sense to have the old security patch from April 2017.

If you didn't root and didn't install TWRP, you should be receving OTA upgrades up to b399.

If something is wrong you may try to do Factory reset with wiping Internal memory (before that, make sure you have clean stock firmware, ie no root or TWRP) and hope for OTAs then

Alternatively, put again TWRP and upgrade by HWOTA method to b393 (and hope to get OTAs then), or continue by HWOTAs

[Huawei P9 Guides, News, & Discussion] zgfg:
You should at least know what was your model (like L09 or L19), cust (like c432) and maybe to guess your build number (when/how did you install last time).

If you would know your build signature as above, you download its update.zip from FirmwareFinder, unpack and extract from update.app the boot.img by using Huawei UpdateExtractor (search for FirmwareFinder and UpdateExtractor on XDA). Then you flash boot.img - see also

Yeah dam I finally fixed it. This was scary. It still sucks that I can't boot TWRP from recovery for some reason (it just hangs).

I found the latest 'firmware' UPDATE/app here: http://www.stechguide.com/huawei-p9-b502-nougat-update/ which I managed to download, extract the images etc and flash the boot image which worked thankfully.

That seems to be going well, but it couldn't get the phone into download mode, and the phone got into a boot loop. I managed to get the phone into Huawei recovery mode, but it can't find anything to recover to. So right now the phone is broken, not working at all, which isn't ideal. I don't know how to proceed from here, but I'll do some searching to see. Advice very welcome.

UPDATE: I hit a button to continue, it said "updating and stayed at 5%", so I hit go on the unlocker tool again. It seems to be trying to install the update again - it's up to 22%.

UPDATE 2: It seems to be working now. The trick seems to be when you get prompts do the "standard" action it says not the "to recovery" action. Then when the phone is saying "apply update" you have to start the DC Converter tool again.

All in all, a slightly more stressful process than I would prefer, but it seems to have upgraded my phone from the C900 version that hasn't gotten updates since March 2016 to a reasonably new version. Thanks for the good tool :)

Hi there, thanks for the great guide.

Have finally removed the Vodafone junk on the phone.

However on the last step the updater is showing that B166 is the latest rather than B182, any ideas? I am going to try B166 and see if I get prompted again. Am in the UK so have set everything to UK.

Have factory reset everything already.

[Huawei P9 Guides, News, & Discussion] Z-Blade:
Another person ran into the exact same situation as you (see post #21), if you read through the forum, the fix was to do a wipe partition and factory reset after updating to B166 and after this you should get the B182 update via the Updater in the settings menu.

i am on the EVA-L19C20B150 firmware but i decided to take the risk to upgrade and just completed it. now i am on android 7 but my build is now changed to EVA-L09 instead.

tested the dual sim capabilities and it is working fine. will also be monitoring the battery.. Just did a factory reset after install Nougat so it should be pretty accurate with not much files in the system.
[Huawei P9 Guides, News, & Discussion] Z-Blade:
That is the correct version of TWRP. I had issues trying to get in to TWRP sometimes but eventually you will be able to get into there. What I find that works best is to have the phone completely switched off, hold volume up and power, when you see the Huawei logo pop up immediately let go of the power button but keep holding the volume up. If this does not work, you try flashing TWRP again and try again. If this also fails, some people were able to get TWRP working by flashing the stock eRecovery, then flash TWRP again afterwards. You may be able to find the eRecovery image on the net or on this forum somewhere or you can use something like Huawei Firmware Extractor and grab the Recovery.img from the UPDATE.APP file.

Yeah, there has been a few reports of people flashing L19 firmware on L09 and vise versa without any issues, however, the only thing that may may be impacted is NFC. Since L19 does not have NFC, it may crash if you attempt to use it if you flash a L09 firmware. With L09 going to L19, you lose the NFC option in the settings.

I mean if you flash the L19C626 oeminfo and custom.bin from the SRK Tool over a L09C432, you will get a L19C900 due to the fact you will have a L19C626 oeminfo on a L09C432 firmware.
