Failed downgrade from Nougat to MM bricked my EVA-L09

Recently I tried out the Nougat preview on my EVA-L09C636. It was ok but seeing as there was a problem with fonts and I'd lost root access, I began thinking about going back to MM.
To prepare for downgrade I tried using srktool to bring TWRP back (and I think this is my big mistake as srktool uses a TWRP made for MM, not N, is that right?). After I tried to restore TWRP I noticed "not recognised" errors when I connected my phone to PC again.
System recovery using hajuuk's Firmware Updater and HiSuite looked like it would complete but near the end of the process (the restoring system part) HiSuite aborted itself saying my device wasn't supported. This has left my P9 is in an unusable state where the only thing I can access is fastboot. Also I can't turn off my phone - holding down power simply makes it reboot then get stuck at the "Your device ... can't be trusted / Your device is booting now" screen.
Reading around a bit I attempted to unbrick it without any luck:
1. downloaded EVA-L09C636B152 update.zip from http://forum.xda-developers.com/p9/development/rom-stock-rom-eva-l19c636b168-t3419586 and installed Snoop05's 15 seconds ADB Installer.
2. extracted images from update.zip using Huawei Update Extractor and did
Code:
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cust cust.img
then tried rebooting holding volume up + power several times (but never got past untrusted device boot screen).
3. extracted contents of update.zip to folder 'dload' on a blank sd card, trying to force update several times by rebooting and holding down power + volume up + volume down (still never get past the screen saying my device is booting).
At this point I'd be happy to get anything happening on my phone - Marshmallow, Nougat or even some other ROM so I can use my device again.
Any ideas? I'm on EVA-L09 C636.

Hi! I'm not sure how to wipe data, cache or dalvik, because when I upgraded to Nougat this apparently removed TWRP.
Also I'm wondering if trying to use srktool to reinstall TWRP for 6.0 might have corrupted my 7.0 phone?
Is there any way to wipe data, cache, and/or dalvik now? Or are there other things I could try to unbrick?

Although my phone was in a pretty bizarre state - it would get hot and sit on the booting now screen until battery died - I was able to use DC Phoenix to make it boot up again. At that point it had no themes and only KitKat-esque icons. A reset and upgrade later icons and themes work and I'm back on stock Marshmallow. Here's an outline:
1. Google "Huawei Bricked phone repair guide with DC Phoenix", go to the first result and look at the instructions (I can't post URLs yet).
I used Method 1. But note! The newer versions of DC Phoenix are missing a feature that the instructions make clear you have to use. To get the original version used in their guide, you have to download the latest version of DC Phoenix, open it on your PC, then click "Enter Support Area" which logs you in to a download section. Find "DC Unlocker Softwares", "DC_Phoenix", then download DC_Phoenix_v14.rar and run that instead. Whether it's Method 1 or 2 make sure you complete it - i.e. the fastboot flash step AND a step they call "flashing in upgrade mode."
(Also note that for DC Phoenix you want to feed it the oldest version of firmware available for your phone, in my case b152. This is because themes and icons won't be fixed until it receives the next version of firmware as an update.)
2. Once I did the fastboot and upgrade flash, I did a system reset from the Settings app trying to get themes and current icons again. (This didn't work but doesn't do any harm or might have helped somehow further down the line).
3. I used hajuuk's Firmware Updater and HiSuite to upgrade to the next version of firmware available (in my case b168).
3. All fine and your phone is back to stock - icons look nice again and local themes are back. To get the original icons layout, go to Recents, hold down on the Trash Icon, show system apps, and Clear Data for Huawei Home.

P9 Update/Recovery Brick

Hello guys. I've been constantly trying to make my P9 L09 work again after I tried out a beta of emui 5. After trying to get back to stuck a lot of times, with many different OVA's my phone has done nothing but boot into eRecovery. It says "update succesful" but then it will be in a boot loop into erecovery asking me if I want to repair through wifi. I have no idea what to do now. Since the wifi thing just fails. I've tried everything and right now I just want to back to stock. But not even Huawei's own Firmware seems to work. I am from Denmark and I was on a EU firmware B182 to start with. I did not unlock my bootloader or root anything, only updated with vol up, down and power button. I tried to get it to hard reset, but it only gives me the option to restore via. wifi.
The problem starts as soon as it has finished "Optimizing system", please help, and be careful when updating to unofficial beta! ^^
If I find a way to resolve it I will post it below!

I think your phone C432 so try this http://forum.xda-developers.com/p9/help/missing-themes-compass-icons-t3519338
Upload files sd card other phone or pc, open your phone dload mode (press vol+ vol- and power button) and ok.

FIXED!
:laugh::laugh::laugh::laugh:
Okay so I fixed the issue. I almost gave up, but I had installed the latest OTA from Huawei's website, and after many attempts at doing a hard reset it finally gave me the option to clear cache and reset the phone to factory. Maybe I had to time the buttons better or maybe it just sorted it self out, but now the phone is like new!
So if anybody runs into the eRecovery boot loop, be patient and try to reset it many times! It might sort itself out.
Thank you for help by the way!

I think I've bricked the Huawei P9

I have a European Huawei P9 EVA-L09 model which I adore. It was running Marshmallow and EMUI 4.1. I found a Nougat beta ROM and I tried to install it but have left it in an unusable state.
I don't think the phone is rooted but I do think the bootloader is unlocked.
I can boot into 3 modes.
Mode 1 - Just reboot
Huawei eRecovery where I get the options to download latest version and recovery, Reboot and Shutdown. If I select the Download latest version and recovery it setups my Wifi and then fails with the message Getting package info failed.
Mode 2 - Power + Vol Up
It boots into a screen that gives me the option to Reboot your System Now, Wipe data / factory Reset , Wipe Cache partition. Selecting Wipe Data/Factory reset returns back to this screen with an error - Red Exclamation mark. Selecting Wipe Cache partition seems to perform a wipe and returns to the original screen with the 3 options again.
Mode 3 - Connect to PC with Hisense and power + vol down
This goes into an android recovery screen which is white with a green android displayed
I have the USB drivers installed on my PC but I cannot see the phone in Windows explorer when I plug it in via USB. I do hear the recognition tone that Windows has recognised that a USB device has been attached. The Huawei PC software doesn't recognise it unless I go into the white android screen and select recover. This always fails saying it cannot find a package.
I have installed stock P9 Marshmallow firmware on my SD card in a dload folder (which is how I bricked it in the first place. When I hold Vol up and Vol Down and power it starts installing but then fails about 40% - 50% through. I have tried multiple versions of the L09 firmware but none of them install successfully.
I am not very technical and not an android expert so cannot say I have done everything perfectly correctly. #
Is my phone bricked or is it possible get my phone back working?

You can get your phone back, search the forums for dc phoenix, which has helped people including myself.
The other option is to go the huawei website, and look under downloads for p9. Find the two firmwares for beta rollback and follow the instructions, although i am not 100% confident that will work for you

use dc phoneix ... i was the in tha same condition

So I have installed and tried install a few different ROMs to the phone. DC Phoenix recognizes the phone as it comes up with the IMEI and version in the left hand window. It seems to install the ROM sucessfully.
I get a message at the end saying it finished successfully but when I boot back up it just goes straight into the same eRecovery screen I have tried B166 and B322 and no luck. Is there anything different I should be doing?

...and now I have a new issue
Thanks for everyone's help. After downloading and trying about 10 different ROMs I was able to get a Nougat ROM to install. Now I have a different problem
1. When I reboot I get a verification failed message. I get an option to go to eRecovery (which works the same as above and doesn't find a package)
So what I really want now is just to get back to stock Marshmallow and not have a verification message and not have some Nougat version that doesn't look like the official Huawei ROM.
So what next folks?

I encountered the exact same problem a few days ago. I didn't try DC Phoenix, instead sent it to Huawei for repair, claiming the phone was in a boot-loop I couldn't recover from.
They have fixed it now and the P9 is on its way back to me. What's strange is that they have swapped the whole motherboard for a new one! Didn't expect that.

Huawei P9 Black Screen

Hello.
I got a Huawei P9 L09 with an unlocked bootloader and after flashing a few roms onto it I noticed with the last two flashes that whenever I lock my phone it appears that the screen stays turned off no matter what and until I reboot the entire device. I only can see the screen after it's turned on, can still use it like normal until I lock the phone. I also noticed that I can't register fingerprints (even if I deleted the old ones before flashing a new ROM) any longer at the exact same time the black screen problem occurred.
I tried to run m00nlight before and with this ROM the problem already begun. Now I installed Bluewei (believing m00nlight had this one problem by itself but it didn't) and the same problem occurred again.
What did happen to my device? Did I miss something or do I need to flash a certain image to repair it?
Edit: I found that the finger prints still were set since Bluewei was installed. I could remove them and the fingerprint could be set again.
Greetings and happy new year.

Before installing ROMs (all cases except OTA updates), you must remove pin/fingerprint/password protection. Specially for custom ROMs like the above that flash over system partitions.
IMO, go back to stock ROM (and stock Recovery), rollback to b182 (no need to go down to b136). By few immediate OTA updates you will cone back to the latest b39x...
PS Try first a simpler solution: Completely disable lockscreen protection, wipe Dalwik and Cache. If it helps you can later re-enable lockscreen prtection

Sorry for my late response.
How do I actually do a rollback to b182? Do I need certain files or the stock rom b182 for that? And how do I install them?
I often tried to put the update.app into the dload folder on my SD and held Power + VolUp + VolDown, however it always said that the update failed, no matter what I tried.

If you are customization C432 here are the steps:
1. Download Rollback package http://download-c1.huawei.com/download/downloadCenter?downloadId=92087&siteCode=sk =>Unzip it, move it to dload folder do the 3 buttons combo. This will change your customization to C900 which is called interflashable.
2. Then download http://download-c1.huawei.com/download/downloadCenter?downloadId=91706&siteCode=sk =>Which is full firmware B182 (your customization will be normal again C432). Unzip it, move to dload folder and perform 3 buttons combo and voila, you are on B182
This will LOCK your bootloader and FORMAT(enrypt) data!

Missing Camera, Calendar, etc after factory reset

Hi all, here are my phone specs currently:
EVA L19
C636 B393
EMUI 5.0.1
Android 7.0
bootloader unlocked
magisk installed
The phone has been great for the past year, but yesterday I did a factory reset (maybe bad move, should have done TWRP wipe) and there are no essential apps anymore like camera, calendar, and the rest.
I've been scouring the forums looking for a solution but most of the download links are dead.
Tried to do an update via HiSuite but nothing happened after installing.
Any other ideas? I don't want to install a custom ROM as I prefer the stock camera app.
Thanks!

Try deleting Dalwik and Cache from TWRP or deleting Cache from eRecovery (switch off, connect to charger!!!, press and keep pressing Vol+, boot by Pow)
You could also try again Factory reset immediately followed by Wipe cache - both from eRecovery
There is also an option in eRecovery: Install latest firmware, you can try but not sure would it work since Huawei apparently removed P9 firmwares from their servers
Otherwise, you would need to find (it was easy in the past when FirmwareFinder worked), download and reinstall your EVA-L19c636 b393 (or newer)

Hey there, factory reset from both phone and TWRP didn't work. eRecovery can't find package info too.
So I downloaded the firmware now and put the dload folder on my SD card but I can't force it to update. When I press the vol keys +- and power, it just says "your phone is unlocked and can't be trusted etc..." and then just boots normally. I can't access ProjectMenu using the *#*# codes either.
Any other ideas how to flash this firmware?

Unfortunately, no other idea but try to find DLOAD package.
Several other users asked similarly, pleas see the other recent posts here for P9 - but generally, it will be hard because Huaweu removed firmwares from their server.
See in those other threads/posts for alternative catalogs.
Unfortunately, c636 is relatively rare, consider rebranding to c432 - and again, look to thoso other threads, recent questions and answers

That's where I'm stuck though... even if I have the firmware I can't force update it by the button method of the secret codes method...
I'll try to flash via fastboot and hopefully it works.

Update: got the C636 firmware and the flashing steps here:
Huawei P9 [ROM][Android 7.0][EMUI 5.0.1][European Firmware b394]*MagicRainbow* v3
