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.

Sent from my VIE-L29 using XDA Labs
@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 am now on C432B182 :good:

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.
Only http://download-c.huawei.com/download/downloadCenter?downloadId=92743&version=363740&siteCode=de
Then
http://download-c.huawei.com/download/downloadCenter?downloadId=91783&version=358257&siteCode=de
'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.......

Try following post #4 instructions from here: https://forum.xda-developers.com/p9/help/failed-downgrade-nougat-to-mm-bricked-t3464156
Hello folks,
so a friend of mine is a complete noob and have this problem with his p9 plus.
The phone keeps rebooting itself in an endless loop, i can't access recovery and only when plugged in to the PC i can access fast-boot.
Phone is locked, FRP Lock.
With getvar command i managed to get this info:
rescue_phoneinfo: VIE-L09C113B170
seems that there is no full zip of this rom anywhere just partial ota (found those with firmware finder) but even with that when i try to flash recovery i get command not allowed.
On the fastboot screen of the phone i have this reboot reason AP_S_PANIC
anyone knows a how to get the phone out of this? (i was thinking that maybe unlocking the bootloader could be of any use, but in the request page it's needed the Product_ID and i don't have it. (can't *#*#1357946#*#*)
I don't know if it does work in a locked bootloader.
I have my P9+ for a week and maybe if you download a firmware compatible with your version and try to 'hard' update the phone, using a SD card with a update file on a dload folder and restarting the phone pressing VolUp + VolDown +Pwr, you can restore your friend's phone.
I'm sorry if I didn't help, I am myself stucked trying to rollback my version to MM and have the NFC and the Bluetooth working again...
myself also got this problem..please anyone..
Hello, I've been using my P8 Lite 2017 at Android 7.0.0 firmware since it last got bricked and then I tried update it through TWRP and got no success. I downloaded the dload update for Android 8 for my device and put the files in the sd card. Then I went to dload and it installed succesfully from there. Then the phone rebooted and then this Error Mode screen popped up. I got the same screen earlier when trying to install Android 8 from TWRP but got out there. I was able to get to fastboot but not TWRP or dload. Then I unlocked my bootloader from fastboot in hope that I would get in TWRP or dload but no. Now the phone is just doing reboot loop with the Error mode screen and I can't seem to find any way to get out of it. No dload no fastboot not anything. If there is not any fix for that couldn't I solve the problem by changing the motherboard or changing an specific part in the motherboard? But yeah, that is my problem right now.
Any help will be appreciated
