Hey man, I got a problem just like you and this is the way I fixed it.
Download the Huawei update extractor:
https://forum.xda-developers.com/showthread.php?t=2433454
And use this to open your Update.app you already downloaded.
Extract the 'boot.img' and the 'system.img'.
Now you need fastboot, follow this tutorial:
https://www.xda-developers.com/xda-...tall-adb-and-fastboot-system-wide-in-windows/
Now open terminal/cmd/powershell and open the folder the boot.img and system.img you extracted are in.
Connect your phone in fastboot and run the following commands:
fastboot flash system [Extracted_System.Img]
fastboot flash boot [Extracted_Boot.img]
fastboot reboot
This resolved the issue for me, I hope also for you!

Hi Jatan,
Thanks for the reply. I tried that as well with a couple of stock images but all i got was a blank screen. Can you share the stock image that you used?
:good:

for most Stock images when i try to "Fastboot flash system d:\System.img" ( system.img is in D: in my case), i get this error
FAILED (remote: sparse flash write failure)

How did he brick it? What was he specifically doing (nougat update etc.)? Do you get the same error when you try and flash a boot image, stock recovery or other partitions?
Can you install twrp? If so, try wiping the system & boot partitions in twrp, then try flashing boot & system again in fastboot. If he'd updated to nougat, then you'll need to try and flash the rollback package first then dload a Marshmallow rom and go from there

I would suggest using this tool:
https://forum.xda-developers.com/p9/development/huawei-p9-eva-l09-eva-l19-eva-l29-tool-t3591358
to install this tool to unlock bootloader and install twrp.
After unlocking your bootloader everything on your phone is gone though.
Then in twrp you can try to repair your your partitians by going to wipe->advanced wipe->repair or change...
And thereafter continue with the steps is provided earlier or install a new rom, this is up to you.
I hope it fixes it for you.

Hi colthekid,
He just went nuts and wiped everything he could see in the twrp.
After that I have tried to write this via the method jatan suggested:
VNS-L21C185B360
from http://www.stechguide.com/download-huawei-p9-lite-b360-nougat-update/
still no boot.

I'l try that and update.

i have twrp. repaired the partitions. did the flast via fast boot using the above method
"Now open terminal/cmd/powershell and open the folder the boot.img and system.img you extracted are in.
Connect your phone in fastboot and run the following commands:
fastboot flash system [Extracted_System.Img]
fastboot flash boot [Extracted_Boot.img]
fastboot reboot"
and still the same. It flashes the files fine. but at boot i get a black screen.
I think im using the wrong files. Can anyone please share the link for a full stock rom nougat , or a roll back from nougat to mm (i flashed this VNS-L21C185B360 latest)

or maybe i need to do write the oeminfo or something. Read it somewhere. not clear on what it is

solved my problem.
Putting the puzzle back again:
I think the genius removed the oeminfo along with everything else he could see in the twrp wipe menu.
I tried to put multiple firmwares on the device nougat ( as he updated) but the boot still showed blank.
As soon as i flashed the oeminfo --> then MM firmware, the device booted up.
Thank you so much everyone for your help. Really appreciate it :good::good::good::good::good::good:

Excellent! :good::good:
And I'm sure your friend is glad to have a working phone again!
Explains why dload wouldn't work as well. As far as I'm aware the update.app checks oeminfo to make sure the firmware is compatible. Hence if you want to debrand a phone to C432, you have to flash a C432 oeminfo before the C432 update.app will flash successfully. No oeminfo=no compatibility for anything!!!

hi,
please help unbrick my P9
I can't get into fastboot, the only one thing it boots is the eRecovery, (system partition damaged)

somehow i managed to get to fastboot but trying to flash system get error
sending sparse 'system' (449861 KB)...
OKAY [ 14.749s]
writing 'system'...
FAILED (remote: sparse flash write failure)
finished. total time: 15.142s
Update: To get into fastboot is very important that smartphone is connected via USB to PC, then Power-button and VolumeDown together till Phone gets into fastboot.
from there flash TWRP, and reboot to recovery, after that install full Update (Files and guideline is here in first post part 3 and 4 https://forum.xda-developers.com/p9/development/rom-huawei-p9-magic-rainbow-t3601064).

How to Root p9 plus VIE-L09

Hello guys im new to the forum,
I wanted to root my phone a p9+ VIE-L09 with android 7.0
I tried the whole afternoon with no success and I think I almost bricked my phone.
from what I have understood I have to
Enable fast boot <---- DONE
install TWRP <---- don't know what to do
Root <---- ?
I tried using droidth's SRK tool but doesn't work for VIE-L09 I think?
sorry I'm a noob

Unfortunatly it doesn't work when I need to reboot in twrp and install the root package the device is stuck on loading screen with "your device is booting now..."
it seems like it cannot load twrp recovery?

No recovery tool supports VIE-L09 model (TWRP/CWM), I tried also with One Click Root but the dont support the model I gues this phone cannot be rooted because there is no recovery support

Yes, twrp should work, you must have the wrong twrp or doing something wrong.
https://twrp.me/devices/huaweip9plus.html

try TWRP from This post : https://forum.xda-developers.com/p9-plus/development/twrp-t3584486
boot into bootloader
use this cmd : fastboot flash recovery2 twrp-3.1.1-1-vie.img
then this cmd to reboot : fastboot reboot
then press VOL+ 3sec

Did this work? I am hoping to root my Huawei P9 VIE-L09C02 with B350 (P9 Plus with Vodafone Stock ROM, EMUI 5.1 & Android 7.0)

Normally it works, but your bootloader and FRP must be unloked

You need a stock recovery to flash stock firmware...

I overflashed only the kernel, so the phone didn't boot, so i tried to find a kernel to flash back, so the phone is booting again, the only one worked was that custom one, but not stable.
So I'm trying to find another better working kernel to flash, or an alternative way to reset my phone, but my recoverys aren't working.

Do you have the marshmallow update pacakage(one you downloaded to update the phone to marshmallow) if you have then extract it and place the dload folder inside a memory card and place it in your phone, then while switched off press power+volume up+volume down all at once and wait until your phone vibrates then leave the buttons and let the software do the work. Hope it helps:good:

If you have unlocked bootloader just flash twrp version for your device and download any MM version Fullrom.zip using firmware finder and flash it through twrp.
Before flashing new rom wipe all partitions from twrp.

Can't get TWRP to work and can't get into OS

I really messed up when trying to root my phone.
I think i accidently flashed an incorrect boot.img to my phone.
Now I can't get it to boot anymore.
After this I now can't even let my XZ3 boot into twrp recovery also.

Did you apply the vbmeta parameters?
Did you tried magisk 19.x? (19 may generate bootloops, I recommend my bundled 18.1)
You can always get the stock boot.img from the boot.sin in the stock firmware (April, the may twrp is not published).
Just unsin.exe the file (unsin.exe from XDA).

The latest (without twrp support, because I shared the first build on telegram for testing) is downloadable via Emma.
You could also use xperifirm and newflasher from XDA
In xperifirm you can choose the region, hopefully one region has still the April firmware.
PS: I see notifications for new posts or answers easily in my big threads, but it gets difficulty for the different device sections on XDA (in the app).

You could also use xperifirm and newflasher from XDA
In xperifirm you can choose the region, hopefully one region has still the April firmware.

xperifirm I can use. But Emma won't recognize the phone obviously as it doesn't boot.
You mentioned the april release. Is that necessary?

Just if you want to install twrp on your phone.
The April twrp may "fastboot boot twrp.img" with broken decryption but an installation would only lead into a not working twrp.

At this moment all I want is to be able to boot it again.
But everytime I try to fastboot a boot.img to the phone I get:
FAILED (remote: 'Failed to load/authenticate boot image: Load Error')

Do you use the newest fastboot version?
And the xz3 twrp?
Execute
fastboot -v
Please

Oh. Maybe 28.0.2 or 28.0.1 are working better?
Did you boot the stock firmware without any modification once first?
Edit:
Interesting
28.0.3 must be so new that even google didn't publish a changelog.

When I got the phone I booted it.
After that I managed to unlock the bootloader.
Then I tried to root it.
And that's when I think I fastbooted the wrong boot.img.

Maybe yes.
I never saw this message. Hmmm.
At least one xz3 user I know from is happy with the twrp.
Weird, very weird.
I whish I could reproduce it.

TWRP worked until I messed up the boot.
When I now try to fastboot flash boot boot.img I get this:
FAILED (remote: 'Error flashing partition : Volume Full')

I managed to get it to boot to twrp. I guess at some time I set-active it to b. Setting it back to a solved the not booting twrp.
Now I used the vbmeta.img from twrp to set vbmeta.
Gonna try rooting it again now.
OS not booting yet.

I recommand flashing the entire firmware via newflasher.
Remove the userdata.sin so you don't wipe your phone.

So, I just found out You're the developer of what I downloaded.
Can I flash this one:
H9436_Customized CE1_1316-3759_52.0.A.3.84_R9B.tar.gz
through newflasher?

Muahahahaha [emoji14]
You mean my old uploaded firmware?
That's just the last version before Sony changed the DRM
Better you use the 52.0.A.8.25 , it is the April stock firmware and compatible with the newest twrp so far.
I hope it is still available through xperifirm.

Ok, thanks so far. You pointed me in the right direction. Hopefully I get my Xz3 running again. ??
