Hello. I recently got a P9 (model EVA-AL00). Since I lived in US, I figured I might debrand the phone.
I followed this guide to unlock my bootloader and root :http://forum.xda-developers.com/huawei-p9lite/how-to/guide-unlock-bootloader-twrp-root-t3405701 and this guide to help me debrand: http://forum.xda-developers.com/p9/how-to/vdo-guide-how-to-debrand-huawei-phone-t3410045.
I unlocked the bootloader, install twrp and root with no problem. However, after I changed the oeminfo my phone reboot and I lost root, twrp, and the bootloader is locked again. Now when I tried to enter recovery mode with cmd, I get Command not allowed error. Furthermore, my phone is now only showing EVA in the model number. I am also getting a message saying my device has failed verification at startup. I am officially stuck.
Any help or pointers would be appreciated. Thank you for your time.
Get a full stock rom for your model,unzip it into the dload folder on your external sd and then hold power and both volume buttons to reflash the stock rom.
Yo dude did you fix it?
fix it?
same problem ((((((crying:
Sorry for the late reply but that did help me to fix my problem

If you have C432, try this:
1. install via sdcard + 3buttons UPDATE.app from HUAWEI_P9_Rollback Package_EVA-L19_from Android 7.0_EMUI 5.0_to Android 6.0_EMUI 4.1_C900B300

try installing 6.0 firmware for you model.
i cant go to eRecovery, i cant even shut down device - only full discharge can make it.But i can go to fastboot. Ive tried with fastboot commands but i have locked bootloader and every time my flashes are rejected by phone. The simpliest metod - HiSuite send me message: "no recovery packages are found for your phone model". It should be a way to unbrick it with fastboot but i dont know how.
Hi I was in your shoes yesterday I had to pay for the dn Phoenix to fix my phone it uses a backdoor to install firmware from fastboot
You could try and look for the backdoor commands I found this , I would post a link but can't yet

I will try to send my Huawei to warranty service and if they wont repair my phone ill pay for DC Phoenix too
I had the same problem!
Hi there.
Was in the same situation as you not so long ago.
Get a micro SD card, plug into PC, create a dload folder then download the rollback file from the Huawei website.
I'm a new user so can't post URL. Just Google "Huawei P9 rollback" should be the 2nd option (consumer.huawei link)
Put in the dload folder and put into your P9.
Press and hold power, vol up and down together till the Huawei logo appears and let go when you feel the vibrate.
This should force update and restart. (does not rollback to email 4.1, only unlocks the rollback from emui 5)
Next you need to download your previous firmware, in my case I'm in the UK with unlocked P9, so I downloaded EVA-L09C432B166.
Same again, put micro SD into PC, delete the rollback file and put your firmware in its place.
Put back in the P9 and repeat the above force update.
This will put you back to working stable stock.
For further reassurance, download a build previous to B166 so when it's up and running you can search for an OTA update to make sure all is in order.
Hope this helps.
Did you meant that the rollback flashes without going to eRecovery? I said some posts earlier that i cannot enter eRecovery so i cant dload anything. Im stuck on Huawei logo all the time do you think than i can flash something via dload without going to eRecovery?
erecovery is different.
I'm saying to do a force update, but in order to do so you need a microSD card.
Erecovery involves holding power up while connecting to PC in order to use HiSuite etc to recover.
Force updater tells the phone to search for dload folder on SD card or phone and install the update before trying to boot up OS.
So, if you connect microSD to your PC via a card reader etc and not via your phone, you can create a dload folder, download the rollback file from Huawei (above) the file is only around 80mb or so, plug the SD card back into your phone while powered off, hold down Power + vol up + vol down. The Huawei logo will appear, when it disappears let go of all the buttons. This should bring up the Update screen.
At this point the phone will install the rollback file. and this will bypass the rollback prevention in emui 5 and therefore allow you to install a previous emui build (4.1)
Again though your phone will still not boot at this point as there is no OS working or installed.
So you need to download the corresponding firmware for your phone/country/operator. Once downloaded, remove the memory card from the phone, connect to PC via card reader, delete the rollback file you placed in the dload folder and replace it with the downloaded OS and repeat the process used to install the rollback.
From there you should be back to stock marshmallow.
I should point out the files you download may be in zip folders. You need to extract the "update" file and that's what you place in the dload folder.
Hope this all makes sense, if not I can make a YouTube video and post it.
Good luck.
Now i know what did you mean, but sadly i cant update it too. I tried with my friend's P9 and when i hold these 3 buttons then shows special update screen and in my P9 it doesnt probably because of my bad flash rollback for P9 EVA-L19 and i have EVA-L09 model

You must first make a step.
Only http://download-c.huawei.com/download/downloadCenter?downloadId=92743&version=363740&siteCode=de
Then

're After You on MM and then can do what you want.
In the first link is a guide.
I did the same thing is what you doing today I've tried this and it fixed my phone

The rollback package for L09 model is here: http://download-c.huawei.com/download/downloadCenter?downloadId=91892&version=363759&siteCode=es
Inform the results please.
I made a video to better understand. This wideo is showing that phone isn't searching any dload folder. https://youtu.be/oD9AI_6SqLs
edit: i have tried your advices to put rollback and try to dload it and then same with firmware but there is no reaction i didnt see there any circle with progress of flashing (like it was before i flashed rollback for L19)
Mine is now doing the exact same thing - I too tried the dload method to update from C432B182 to C432B361 and it's screwed my device up too.
Until I tried to use the 'rollback' package, it would at least allow me to power off, so I could get back into the Update screen - after doing that, and trying the B182 again, it's got into this position where I can do literally nothing with it. No combination of buttons, no matter how long I try to hold them, seems to do anything.
An update...
After letting my battery drain completely, I have been able to get into Fastboot mode, by pressing and holding the Volume Down button whilst connecting a USB cable to my PC.
From here, I have been able to run DC-Phoenix, and have been able to write some .APP files to it - which has at the very least got it booting into eRecovery, rather than the boot loop it had before, but is still not fully booting.
It looks like I might need the full, original firmware, in order to proceed?
And I've got about 68 hours left to flash using DC-Phoenix, or I'll have to spend another €15!
Yes you download the original firmware unzip it and put it in the "dload" folder of SD card then do a force update. Hold all the buttons vol + vol - and power
Help Please.......
So I've owned sammy devices before in the past and never been afraid to flash custom kernels/roms etc on them. Since the p9 was the first Huawei device I've owned i was a little scared to flash it. But it got too much for me and i tried, and fail Now i have a P9 that doesn't work and a very upset wife because I've killed my phone.
So what i did was tried to flash via dload 3 button method a nougat fw (official)but had no camera/file manager/calendar etc. Found it was possible to downgrade via flashing a downgrade fw. I cant remember what nougat fw i tried to flash but in the about device the build number was nrd10testkeys or something like that. My official fw before was EVA-L09C706B145. After flashing the downgrade fw my phone rebooted and just hung at the Huawei boot splash screen. All i can do now is access fastboot by holding vol - while plugging in usb. I cant access recovery/cant boot past Huawei splash screen. I have tried fastboot flashing via adb but it fails due to permission error (thinking because of locked bootloader?) Have tried using Huawei updater with hisuite to recover device, download, unpacks and installs recovery to 99%then fails. Pleaee help me fix my phone so i can get back into the goodbooks with the wife.......
Tia all
Try following post #4 instructions from here: https://forum.xda-developers.com/p9/help/failed-downgrade-nougat-to-mm-bricked-t3464156
I've been trying to contact huawei for a couple of days, trying to get my p9 back to alive.
well let me explain how this is happened :
couple of days ago, I was on nougat firmware and few games that I play isn't optimized for nougat yet so I planned to downgrade to marshmallow via rollback and update.app package. First I install the rollback package via internal storage and its success, second, I rebooted phone and insert my sdcard to install update.app from official huawei and its say success then it rebooted itself after 100% flash. Then I realized that my phone isn't came to boot, I try to reboot again but no success getting to boot screen. I try to reflash the update.app thru dload mode but dload mode isn't boot anymore. trying to boot into erecovery but it never show up. Think I'm broke my recovery at this state. Then I try to boot into fastboot mode and its success. Unfortunately, It says frp locked and phone locked ( yes I formatted my phone on nougat earlier thinking that the cause of lag is maybe I dirty update it without clearing data etc like flashing firmware and I forgot to turn frp off )
This phone is mine and not stolen. I can provide you my google data and prove it with ss on my google account manager that this phone is already been bind to that account.
I wanna know how to turn frp lock off?
Trying to fastboot frp-erase but didn't solve my problem
Trying to fastboot frp-unlock but it ask me for a password (trying to insert bootloader unlock code but it says password matching failed)
Trying to flash anything but it says remote: command not allowed since my bootloader locked again due upgrading to nougat.
And, I dont want to pay for dc-phoenix since I want to learn myself how to do it from you guys
Thank you!
You won't learn anything, because your phone is ****ed up In real mess and you must pray even to recover it with DC phoenix ... and yes, you must pay them

When FRP is locked, we can not help you. Use DC Phoenix for repair.

i can't remember the version but im sure it all arounds in 2.1...something
no i wasn't load the Nougat version because i know i am MM the only thing i remember is the TWRP i load is from SRKTool Lod Chong there was an option there to install twrp recovery
can i be able to enter the fastboot ?
if i can go over to fastboot i can repair this
but i can't go fastboot
volume rocker technique doesn't work
even using adb reboot bootloader too
when i am doing volume down ( hold )
the phone only vibrates then stuck at logo
even when its connected to adb command
when the phone reboot it stuck at the logo
can't go to fastboot ?
is there any way of forced
