P9 Bricked - Boot loop please help

Hi all,
I am facing severe problems with my P9.
Initial Situation:
Started with a brand new P9 with T-Mobile cust Firmware C150
What I did:
I unlocked bootloader successfully and rooted the phone. Then changed OEM info from C150 to C432. So far so good.
After that P9 booted into factory restore and restored itself into C900 Firmware. Bootloader was locked after that.
I unlocked bootloader successfully for a 2nd time.
Current Situation:
Now when I boot the phone it says: "Your device has been unlocked and can't be trusted" .... Your device is booting now... => But it never boots into OS. It stucks here forever.
When I press vol up and down and power for some seconds I can at least access TWRP. When I try to reboot in TRWP it says "No OS Installed".
But how can I do a stock recovery or install a working Android OS in order to get the P9 into normal boot Modus again?
Please help me.
Solution summary:
Issue solved by using the dload method to change to C432B182:

If u have a sd card u can put it in another phone if u have and create a dlod folder, put the Firmware u need in it and then switch it to your P9 and try to upgrade. Since your phone is C900 i think something went wrong in the debranding so use a full stock C150 firmware or try with this B136 Firmware with dt and hw folder toghether with update.app in dload folder.

@panosm763: Thx for the Video link. I worked according to the same but after changing OEM info phone booted with red warning Screen and installed a fresh C900 Firmware Version. Then after opening bootloader again, SRK Tool cannot connect to the phone anymore maybe due to the fact that usb Debugging mode is not turned on (and cannot be turned on because OS is not reachable)
@Mostar088: I tried the dload method yesterday with the Firmware from the link you shared. Unfortunately without success. The phone did not recognize the Firmware and did not load the same. Maybe because bootloader is still open? I have no clue why this method is not working

Issue was solved.
It worked out fine using the dload method described in here:

I've tried many things to unbrick my phone but i cant do it. flashing system via fastboot is impossible cause it says that it cant be written. i have no root ant no bootloader unlocked. Please help me guys QQ

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
2. install via sdcard + 3 buttons HUAWEI_P9_Firmware_EVA-L09_Android 6.0_EMUI 4.1.1_C432B182_Western Europe

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.

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

I had the same Problem but i cant Garantee that this will work for you but it worked verry fine with my (EVA-L09).
1. I started my P9 in Fastboot Mode (Hold Volume Down + Connect USB Cable)
2. I used the Programm DC Phonix 35 at First and used Method 2 (see Link). I used the File for the Dual Sim Version (EVA-L19, you find the File on the Data Base of the DC Phonix Tool) of the P9 because there is no Version for the Solo Sim. But it worked verry fine.
3. After i completed Method 2 i started the Phone and saw that it worked again but it is an verry small android version with no function exept Phone Settings and some Huawei Internal Software.
4. I restarted the Phone into the Fastboot Mode and used Method 1 with the Update.app of the Firmware EVA-L09C432B136. But only do step 1. Step 2 will not work !! After the Process was completed i restarted it and it worked.
5. After that i Searched in the Android Options for an Update and found the EVA-09C432B182. You need to install it to fix some errors. After the Phone installed by itself the B182. I used the Huawei Updater with the Hisuite to Upgrade to B361 because the Phone didnt found a new Version by itself. Guide for Huawei Updater with Software Links
And now my P9 is on the EVA-09C42B361 and can find updates by itself i know the new B383 is out but i will wait a week than the Phone will find the Update by itself and i dont want to Brick it again. In the next Days your Phone will show you that the B383 is avalible.
I hope my Little Guide can Help you. If you have any Problems please write me I know that the DC Phonix tool costs Money but it was the only way it helped me. But i have some credits left at my account i think you can use them if you want
Sorry for my Bad english if there are some questions left please write me

Try to use the Multi-Tool for team MT,maybe it will help you to unbrick your phone,i`ve used yesterday to unbrick a Honor 5C NEM-L21.You will need the update.zip for you phone and Huawei Update Extractor.

Or try DC Phoenix

How do you expect anybody can help you if you don't provide practically no info at all (not even were you running MM, N, O, stock or custom ROM)
- what was the last build you were running (full stock build name, inclvariant, cust, number)
- were xou running custom ROM and which one
- stock recovery or TWRP (which)
- shortly what were you doing when you bricked the phone
Also, do you have bootliader unlock code, and is FRP locked or not (you can see in fastboot).

Do you know how many 'stock ROM and recovery' versions exist, and each may need different procedure to restore your phone
If it is P9 (single SIM, hence L09) -not Dual SIM (L19 or AL10) or Lite or Plus - it can be cust c432, c185 c900, etc, with Android 6 (builds 1xx, 2xx) or Android 7 (builds 3xx, 5xx) - all are stock firmwares
Are you familiar with Fastboot, or maybe the safest way will be to go to service (specially if still under guarantee)

yea i know, and if its way to restore somehow this p9 i will can do that via fastboot, just dont know how
Its p9 single sim l09. i think it was c432 rom

Since you didn't unlock Bootloader it must not be scr***ed up severely.
Try the following (independent of your prev build, no need for Fastboot, open Bootloader and other hacking tricks):
- Power off
- Connect by USB cable to the charger
- Must be in the range of reliable WiFi
- Press Vol+ & Pow (in that order) and keep pressing
It shall boot to eRecovery, giving you options to download and reinstall your whole stock firmware
Advice: When you restore, take and save screenshots from About, to know your build, IMEIs, etc

Ive got error : Getting package info failed

you need sd card. in sd card create "dload" folder, in folder copy this update.app link here oh, first link are for eva-l19 here are for eva-l09
then, insert sd card in phone, press and hold vol+ and vol - and power button (hold all buttons till see update things)
after that, download this (or download all at once) link here and delete update.app in dload folder at sd card, and copy all from this b136 download, need to be 2x folder and update.app now larger file than first. and do dload method once more (vol+, vol- and power till update starts)
ah, but you need to charge pgone atlest to 50% to be succes with dload method!
