Did u upgrade to Nougat by OTA with TWRP on the phone or did u have stock recovery?
[Huawei P9 Plus Guides, News, & Discussion] KBEscalona:
i think so:confused:.. i remember that after successfully installing b180 i immediately updated to B362 (it was present in the updater) knowing it will remove the twrp and re-lock bootloader.
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
That is the problem, u cant OTA with TWRP recovery, your phone will end up with a broken cust partition. If u are on stock recovery now u need to use the Rollback package to go back to MM. Here is the link, when u install the Rollback your phone will show C900 cust so dont worry that is ok, after Rollback u need to install B180. Then your phone should be all stock.

Then it's ok to upgrade to Nougat with OTA.

[Huawei P9 Plus Guides, News, & Discussion] KBEscalona:
A Big Thank you for helping me. I planning to use this phone until it last not planning to upgrade due to its costly. Will provide results later.
[Huawei P9 Plus Guides, News, & Discussion] KBEscalona:
Hi Mostar, I've managed to rollback to MM. Updater already detecting update. i did not push thru with due to i noticed that the themes (pre-installed) for the MM is missing and i tried downloading one from them store and applied to it but nothing happens. Should i update to nougat now or i need to fix MM first at B180?
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
The Themes problem will be fixed when u upgrade to Nougat, now u should be god to go.

Pleade QUOTE me when u send a message so i get a notification.
[Huawei P9 Plus Guides, News, & Discussion] KBEscalona:
Hi Mostar! Thank you thank you and thank you. P9 Plus is running nougat and updates are coming in. B365 will be installed later. Again Thank you for your patience and help. I can still use my phone for another year or so.:)
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
Nice to hear it worked for you! :good:

Feels like a new phone now? ;)
[Huawei P9 Plus Guides, News, & Discussion] KBEscalona:
Yes it feels like new. hopefully it gets OREO:). But i'm liking it now. Thanks again!:good:

B388 appears to be out on FF now (not yet approved as per usual).

Looks to be just another security patch update, don't think Huawei will be adding any further features to this phone (unless, by some miracle, it gets Oreo).

Anyone has a problem in fast charging when updated to b386? My fast charging not functioning since updated:crying:

Yep. i'm using a charger with QUICK CHARGE 3.0 and fast is not recognized.
[Huawei P9 Plus Guides, News, & Discussion] masze:
New C432B379 in FF.

Now there are two updates B378 and B379 but both NOT approved by Huawei.
[Huawei P9 Plus Guides, News, & Discussion] djyoshii:
Using both the Huawei charger (with their own proprietary fast charging) and a QuickCharge (2.0 I think? by Qualcomm) rated powerbank, and both are working fine.

I did have issues in the past and had to send it in for warranty, since then it's worked fine. Was actually surprised the QC powerbank also worked on this phone, as everything I had read prior to that said it only fast charges using Huawei's own wall charger.
[Huawei P9 Plus Guides, News, & Discussion] masze:
C432B378 is now approved in FF

Upgrade to Nougat VIE-L29C636B103

Hi Mostar,

I saw you are an expert!!!

Can you help me to upgrade to N?

Thanks,

Upgrade to Nougat VIE-L29C636B180

Hi Mostar,

I saw you are an expert!!!

I've just successfuly upgraded from VIE-L29C636B103 to B180 (rom in your post) via TWRP

Can you help me to upgrade to N?

Thanks,
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
U must first return to stock recovery and unroot if your phone is rooted.

Does the phone show as VIE-L29C636B180?

U can use SrkTool to return to stock recovery, then flash B180 so the bootloader gets locked.

After that if u dont recive OTA to Nougat u can upgrade by using Firmware Finder.
[Huawei P9 Plus Guides, News, & Discussion] MARCHETTINIF:
Hi Mostar,

Thank you for your answer....

I did it. I putted the UPDATE.APP from SrkTool in the dload folder and pressed vol up + vol down + power. The update process started and finished, but didn't boot. Screen still saying "Your device has been unlocked..... Your devices is booting now" but never boots!!!

Can you help me?

Thanks,
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
Have to go to bed now its realy late here in Sweden.

Try this:

HOWTO:

- download HuaweiFirmwareExtractor and from B180 update.app extract boot.img, recovery.img and system.img

Enter fastboot mode and use ADB.

In ADB enter code:

fastboot flash boot boot.img

fastboot flash recovery recovery.img

fastboot flash system system.img

and then go to recovery and do a wipe data / factory reset.
[Huawei P9 Plus Guides, News, & Discussion] MARCHETTINIF:
The problem is I can't enter in fastboot mode....!!!
[Huawei P9 Plus Guides, News, & Discussion] masze:
B380 in FF (432) (not approved)
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
U should be able to enter fastboot if u do it the right way.

Usb cabel should be in the phone and PC, if u cant turn off the phone hold power until it turns of then let go of power and fast press power and volume down and hold so it goes in fastboot.

I think u can use SrkTool to enter fastboot mode also if it does not work for u, then in SrkTool u can also flash system, boot and recovery.

C432B379 OTA in Sweden today!
[Huawei P9 Plus Guides, News, & Discussion] djyoshii:
B389 out as of last night (B388 still unapproved, however)

Surprisingly there's a few new features, as opposed to the last few which were purely security patches.

What's New

Adds 3D panorama in Camera, which enables you to take 3D dynamic images to show your life in more perspectives. Adds a feature allowing you to edit 3D photos with watermarks, filters, and more advanced settings such as brightness and saturation. Gallery now features a recycle bin that retains deleted photos for up to 30 days. Accidentally deleted photos can be restored with a single touch. Adds a security procedure that requires you to enter your lock screen password every three days, helping you to remember your password. Adds a new split-screen function. You can swiftly split the screen to check your WhatsApp messages by touching the split-screen key when you are watching a video.

Optimizations

Optimizes the App twin feature to support logging in with two accounts for certain apps, such as Messenger. Integrates Google security patches for improved system security.

Fixes

Fixes an issue where the main and twin Facebook apps could not be online at the same time.

Hi All,

I still B387 Huawei update slowly i don't know why?
[Huawei P9 Plus Guides, News, & Discussion] djyoshii:
Yeah same here, also on B387 with the Nov2017 patch. I find it usually takes around 1.5-2 months after release, to be approved. So would assume B388 will be approved for install in the next few weeks (going by past experience).

Not sure of the reason behind releasing these updates, but not approving them for installs. Anyone else have any idea?
[Huawei P9 Plus Guides, News, & Discussion] masze:
I don't think we get any more Nougat updates.

Next is Oreo!
[Huawei P9 Plus Guides, News, & Discussion] ead_25:

I'm in need of assistance!

A friend of mine needs help with his VIE-L29. I need to install some kind of stock ROM on it.

The bootloader is unlocked, and TWRP is installed. When at the reboot screen of TWRP it tells me "No OS Installed".

I've been trying several different downloads to get it working, but have had no luck so far.

What do I need to install an OS? Since I can't start the phone the dialer update isn't an option for me.

VIE-L09-C432
[Huawei P9 Plus Guides, News, & Discussion] Wollu:
Flash stock recovery, Download the official firmware and Googling for dload method.

Good luck!
[Huawei P9 Plus Guides, News, & Discussion] Punchlinern:
Thanks for helping out!

I'm not really sure what happened now...

I managed to install the official firmware (downloaded fromupdate.hicloud.com).

I was doing some other things while it was updating, and checked the process now and then. I saw it at somewhere above 90%, and when I looked at it next time the screen was just black. The phone was not charging or connected to the computer while updating.

I tried a volume button to wake it, nothing happened. After a while I tried the power button, first pressing, and then pressing and holding. No apparent response. It seamed completely dead.

I plugged it into my computer, and heard the device connected-sound.

I pressed and held the power button and could hear the device disconnect and connect again.

When I run

fastboot devices

it shows up in the list (I'm sure it's that phone, no other is connected, and it disappears if I disconnect the phone). I ran fastboot reboot and it reboots, so it responds.

But the screen is completely black all the time. The phone doesn't make a sound or vibrate when restarting.

Is there anything I can do?
[Huawei P9 Plus Guides, News, & Discussion] Wollu:
Try this:

- Check and make sure the recovery is now back to stock.

- Go to this link: https://consumer.huawei.com/kw-en/support/phones/p9-plus/ , make sure you choose the p9plus, and download :

----- P9 Plus Rollback Package (VIE-L29, from Android 7.0 EMUI 5.0 to Android 6.0 EMUI 4.1, C185B300, MiddleEast&Africa) and

----- P9 Plus Firmware (VIE-L29, Android6.0, EMUI4.1.1, C185B181, MiddleEast&Africa)

- Use sdcard and dload 3 buttons method to install P9 Plus Rollback Package ( if it;s succeed, at this point the device will boot)

- Once it boots, use sdcard method again to install P9 Plus Firmware.
[Huawei P9 Plus Guides, News, & Discussion] Punchlinern:
I've tried, but I can't get it working. Since the screen is black all the time I can't really tell if anything is happening.

Do you know if

fastboot devices

would show the device if it is updating?

I tried holding power+volup+voldown to start the rollback. After waiting a while I connect it to the computer, and the device shows up when running the fastboot command.
[Huawei P9 Plus Guides, News, & Discussion] Wollu:
I am not really sure what happened.

Have you double check that there is power in the battery?

Try to charge it for 30 minutes or 1 hour and see if you can turn it on.
[Huawei P9 Plus Guides, News, & Discussion] Punchlinern:
I've left it charging for over an hour, still no sign of life.

My fear for a hard brick is rising by the minute :(
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
U could try Dc Phoenix to unbrick the phone.

[Huawei P9 Plus Guides, News, & Discussion] ArtfulCodger:
Hi guys, just received my P9 Plus (VIE-L29c636b130) brand new but still has MM.

I have read a lot of pages (but not all)...the phone was bought from Hong Kong so has Asian as the country...no problem for me...but I am in Australia if that does make a difference.

I have loaded FF and understand to get to Nougat I need to first load B180...FF doesn't show B180 but does show B182 as approved, so am downloading that.

Can I update with the update.zip file (there were three options) or does one of those contain the cust files or sorry I'm at the limits of my understanding now...just not sure if I'm downloading the correct one. Also FF is showing in the notifications that the Proxy Server is running even though I didn't add localhost and 8080 anywhere, is that automatic now???

Download has completed. update.zip is 1.33GB... So isit ok to update with that one...? Then go straight to B389 to get the latest security patches and 3d...
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
U should use DNS to upgrade, u dont need to add localhost or Port 8080 it does it automaticly.

Use B180 to go to latest MM firmware, and then when u want to upgrade to Nougat u must use a FullOTA-MF-PV Firmware because u go to a new Android system, u can use B362 or B370. When it's upgraded to Nougat u can proceed to latest approved FullOTA Firmware that is B387.

B389 is not approved for upgrade!
[Huawei P9 Plus Guides, News, & Discussion] ArtfulCodger:
Thanks, so I've found B180, there are 3 showing as B180 so I download the largest file...just over 1GB....update to that then I can move to B370...think I have that now many thanks. I'll delete the B182 one I downloaded previously. I assume (another noob question) FF downloads the file to the correct folder in internal storage?
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
Yes it does, just like u recive a OTA. U should not download the update.zip. Use dns and it will show in Updater in Settings of the phone.
[Huawei P9 Plus Guides, News, & Discussion] Punchlinern:
It's alive again! I must admit I didn't expect that!

Tack så mycket :)

Back to square one then, trying to upgrade to EMUI 5 and Android 7.

Nemas problemas,

Dc Phoenix is an incredible tool!

Varsågod!
[Huawei P9 Plus Guides, News, & Discussion] ArtfulCodger:
Ok so tried the DNS it set up the VPN Server but do I then use FF to download the file as the only option shows as update.zip....Phone update still doesn't find anything and Hisuite doesn't either...sorry I've flashed other roms and haven't had any issues....BTW this phone doesn't yet have a SDcard in it...wasn't going to swap the one from other phone till new one all set up.
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
U dont need a sd card, use this guide how to setup dns.

[youtube]2Auy4MvzmWs[/youtube]

1. Select the firmware that you want to install, check if it is available for installation.

2. If the firmware is available for installation, click 'Get an Update through DNS'.

3. Click 'Registr update', then 'Change DNS', confirm the launch of the VPN. The key symbol will appear in the status bar and message in notification bar.

4. Go to Settings->Update and check the availability of the update.

5. For FullOTA firmware, you need to click the 'Download full package' button in the Updates menu, for OTA actions is not required.

6. Compare the firmware size in Fimrware Finder and in the Update application, it should be approximately the same.

7. Confirm the installation of the update. Disconnect the VPN as soon as the download begins.

8. The device will reboot at 100% load.
[Huawei P9 Plus Guides, News, & Discussion] ArtfulCodger:
Ok I was missing the register Update btton...didn't scroll down now it has found it and downloading...

...B180 installed...so now I can use DNS method again to go to Nougat at B370...via FullOTA package...?

Phone updater now tells me there is a new fw available but shows the B180 version I just installed...have I gone into an Upgrade loop?

So it tells me B180 is on the phone but hen finds B180 again and tells me to do a quickupdate...?
[Huawei P9 Plus Guides, News, & Discussion] ArtfulCodger:
So I let it download the B180 update again but it fails...Updater still shows it as a valid update though...so can I just go ahead and do the DNS update to B370 Nougat?
[Huawei P9 Plus Guides, News, & Discussion] cloudlockhart:
Edit: it failed and got deleted
[Huawei P9 Plus Guides, News, & Discussion] ArtfulCodger:
So downloaded B370 seemed to fail verification...is there a better fw to download for Nougat?

I'm on C636B180 and all looks fine...if that means anything.
[Huawei P9 Plus Guides, News, & Discussion] masze:
Yes, install is gonna fail!

You can test this for unapproved files.

[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
Did u use nr 5 method?

5. For FullOTA firmware, you need to click the 'Download full package' button in the Updates menu, for OTA actions is not required.

In Updater in Settings u need to click on Menu and choose Download Latest Full Packege.

So do the process again.

Then when it's done u should recive OTA to B190 and then u can go to Nougat.

If B370 fails try B362 but it is importent that u use FullOTA-MF-PV and NOT FullOTA-MF

Sorry for late answer but we are in a different time zone.
[Huawei P9 Plus Guides, News, & Discussion] Punchlinern:
I must admit I'm confused as to what firmware I'm supposed to install.

Since I started I've worked with versions for VIE-L29. I found that model number somewhere (don't remember where now), and was also displayed in. DC Phoenix.

The thing is that VIE-AL10 is written in the back of the phone. And it was AL10-firmware I flashed to get it working again.

But when I downloaded VIE-C00B198 for AL10 it wouldn't install (using the dload method). It just says "Incompatibility with current version".

How do I know what firmware to download?
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
Check Vendor Country Info what u have in Project Menu, dail *#*#2846579#*#*
[Huawei P9 Plus Guides, News, & Discussion] Punchlinern:
It says

Vendor: hw

Country: eu
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
Ok, if it is hw eu u need to flash VIE-L09C432Bxxx

How much credit did u buy on Dc Unlocker, u csn use it for 72h, u could dowload the Firmware C432 in Download section on Dc Phoenix and flash it. U could also download HCU-Client and check if vendor and country is ok.

Did u get this error when u flashed the Chinese firmware?

NOTE: If you get error during flashing "VERLIST partition" it means your customization version is not same as before, you must do Step 2!

If flashing ended successfully, but phone still does not boot up - means you have flashed incorrect file - must use original Full Stock ROM that was in phone when it was purchased to have highest chance of repair.

Step 2 (not required if flashing successful in Step 1)

After flashing in fastboot, phone should be able to boot up now

Now you need to rewrite model, vendor & country even if it remains same. They must match with customization file that you want to flash.
[Huawei P9 Plus Guides, News, & Discussion] Punchlinern:
I bought DC-Phoenix + HCU timed license, no credits so far.

I can see 2 options in the folder Other downloads / Firmwares / Huawei_phones / Full_Stock_ROM_Firmwares / P9_Plus / VIE-L09C432B370

One with a bunch of European country names and one called update_data_customization_hw_eu. I assume I want the first one?

I tried this, but I'm not sure how to do it. I've downloaded HCU Client and logged in, I tried Read phone info after setting the phone to Manufacture mode as instructed, but it just tells me Phone not found

No, I don't think so, it ran until it said something like "Waiting for phone in download (upgrade?) mode...". The phone restarted into that mode, but it just stayed at 5%. After a while, I restarted the phone and it booted into Android.

---------- Post added at 08:32 PM ---------- Previous post was at 08:24 PM ----------

When I checked the download page at dc-unlocker.com it said Files here currently usable only on DC-Phoenix v39 beta!. You don't happen to know if that is still the case?

It's not written in the support area where I downloaded the files.

Do I flash the file using DC Phoenix, as I did when unbricking it?
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
U should flash the same way u unbricked the phone, u can use it on tje version of Dc Phoenix u have now, v39 is an old Beta version.

Try with B370, and download also update_data_customatomization_hw_eu and put it in the second row like in this guide.

[Huawei P9 Plus Guides, News, & Discussion] Punchlinern:
I went through it like that, and it stopped at the same place this time as when I unbricked it.

The phone stays at Installing update, 5%.

[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
Did u put the phone in fastboot mode?

NOTE: if flashing stuck and phone does not flash automatically in Upgrade mode disconnect phone from PC. Restart phone, put it manually it Upgrade mode (usually it's done by holding both vol buttons and power button - may differ by phone model) Connect to PC if not already connected and press Update on DC-Phoenix again (Software restart may be necessary).

[Huawei P9 Plus Guides, News, & Discussion] Punchlinern:
Indeed, shame on me.

It went through both files and got to Writing device finished OK, but the phone stayed at 99% for a couple of minutes, then it gives the message "Update install failed".

After some nervous seconds, it rebooted, working like a charm! :D
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
That is a common error that it gets stuck at 99% but all is ok.

Nice to here u made it.

So now u are on Nougat? Did u get OTA now to upgrade? B380 is the latest approved Firmware for your phone, if u dont get OTA u can upgrade with Firmware Finder.
[Huawei P9 Plus Guides, News, & Discussion] Punchlinern:
Yeah, Noguat (7.0). Version NRD90M test-keys, whatever that means.

No OTA has popped up, and searching for updates in settings gives nothing.

I'll give Firmware Finder a try!
[Huawei P9 Plus Guides, News, & Discussion] Mostar088:
Hmm NRD90M Test-key is not ok, did u flash the customization file? If not u need to do it again.

It must show as VIE-L09C432B370 or u r stuck, u wont get OTA and u cant upgrade with Firmware Finder.
