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-L09/19 touch screen doesn't work in eRecovery or TWRP

Hi,
I must admit that I am panicking now because looks like i have bricked my phone and no matter what i try to do i am stuck between erecovery fastboot and TWRP.
To give you some light as to what actually happen... I've replaced oeminfo in originally EVA-AL-10 with EVA-l09. I have installed full system EVA-L09C432B136 and everything was fine at that point.
I thought to myself that it would be nice before putting any data to the phone to actually rebrand it to L19 so i do get a dual sim support.
In another thread I've found oem info for L19-C432. I've replaced it and decided to reflash full image EVAL19-C432B161 which i've also found on this forum due to huawei servers being down? (for some reason I couldn't download anything from the manufacture sources) This is when i got a first error message that updated failed due to incompatibility with the device.
I have been looking for some other full packages but whichever one I've put on a SD card, i couldn't get to work. for some stupid reason i thought about updating B136 hoping that during update process incompatibility issue will get fixed. Unfortunately this wasn't the case and even though the update completed "successfully" on the screen, after the reboot, i ended up in eRecovery.
Having oeminfo in SRK tools which worked for me previously i unlocked bootloader again and installed TWRP so i can root my phone and use srk to update OEM info back to 09.
This is where serious problems started to happen. in TWRP I am unable to use touch screen, only volume buttons and power button to confirm. As its a first launch of the TWRK I cannot even swipe to confirm read/write mode hence I can't go any further to install supersu etc...
Do you have any suggestions what can I do to unbrick it? Is there any workaround to get root via sd card? or maybe forcing somehow stock rom L09C432B136 to install regardless? Maybe there is a way to repack update.app so i doesn't look at the oeminfo?
I have tried replacing images (CUST, BOOT, RECOVERY and SYSTEM) in fastboot mode but I am not having any luck whatsoever.
Please throw me any ideas...
Thanks.

Hi azgooon,
I'm having the same problem, even it's a different huawei phone, did you get your problem fixed? How? Thanks for sharing.

Honor 5C - Soft Brick / Hard Brick - HELP??!!??

Hi, well it looks like i have probably hard bricked my phone. After updating to nougat i decided to do afresh clean install. I wanted my phone to as if i had just bought it and came with nougat/emui 5 installed. So i did a factory reset from within the settings menu. But then i thought i would completely erase everything and start from the latest build before nougat, so emui 4.1.2/ marshmallow. So after wiping all the partitions in twrp and then doing a volume up + power to do complete factory wipe followed by using the three button method to install the B130 UPDATE.APP in dload folder on my sdcard, all worked as expected. The update completed at 100% and then rebooted. So there i am waiting for my phone to boot to start the setup process as i have done dozens of times before...BUT...my phone will not boot to the initial setup wizard. It just stays stuck on the Honor logo pulsing animation for ever and ever and ever!!!!!!
So i do the volume up + power button to get to stock recovery and do factory wipe and cache wipe as well. It works as expected so i reboot and once again use the 3 button method to install the update.app on my sdcard. That works as expected and at 100% says its succeeded and reboots. Once again i wait for it to boot to the initial setup wizard but....ALAS...it stays on that DAMN pulsing Honor logo. Ive tried rebooting it several times, redoing the factory wipe and install several times, but nothing. Ive gone into fastboot mode (volume down + power) to try and flash the boot.img and system.img ive extracted from update.app but get the error message -- remote: command failed -- and the same if i try to unlock bootloader. Obviously its not going to work because my bootloader isnt unlocked and nor can i got in to developer settings to enable oem unlock and turn USB debugging on because my phone wont boot past that bloody honor logo.
The only thing i havent done yet is to use eRecovery but i dont have broadband and i doesnt seem to work over public wifi! So i will go to my friends tomorrow and use their broadband and hopefullly eRecovery will download/restore the latest firmware. The only other thing i can think of is to download the original nem-l51c432B102 that came with my phone when bought, extract the update.app file and replace the B130 i have on my sdcard dload folder at present.
Sorry for such a long post but i wanted to expalin evrything in detail to hopefully resolve my problem without going backwards and forwards with questions and answers and taking for ever.
So ANYONE and EVERYONE who managed to read the whole post, if you have even the slightest idea of how to get my phone working, please oh please share it with me. Also my phone is still under warranty so if i needed to send it to a huawei centre to get it fixed would they do it and do it for free??? because eseentialy all i did was a factory wipe/reset and install a frmware and it goes KAPUT!! thats not my fault right????!!???
Thank you to one and all for any wisdom you can share.

please...please....help
So sorry for my original long post people, i simply wanted to give as much detail and info as possible because being vague doesnt help anyone. It seems that might have worked against me.
Please,please any suggestions would be appreciated to the N'th degree! I have tried everything i can think of and i am truly desperate now. I dont understand why i cant get it to work...
I can go into stock recovery and wipe the cach and do factory reset and that works fine, no errors.
I can hold the 3 buttons down to install the firmware package(ive got update.app from B130 build) and that works fine, gets to 100% and says 'success' and then reboots, with no errors.
But either way the phone refuses to boot past the honor logo boot animation and ive left it for hours hoping,praying, it will work after the 32nd time...
I can access fastboot but that is useless because my bootloader is not unlocked and i cant get to developer options to enable 'usb debugging' and 'oem unlock'. So i just get error message 'remote: Command Failed' with any command i type.
But thats madness, i cant comprehend why it wont boot because everything seems to work!?!
There has to be a way to get my device functioning again.
I am pulling my hair out, i am at a complete loss, it doesn't make sense. PLEASE ANYONE ..... please help....
Thanks HONOR-able enthusiasts for any help, no matter how small!

i guess you are trying to update with the small sized ota b130. Use the full Ota b130 instead

I wish my friend. No it is the update.app from the full b130 update.zip. Anyhow I have downloaded the b102, the earliest version I can find and the b130 rollback from nougat to MM version. Gonna extract the update.app from both and try one after the other to install via 3button method. I am just waitingfor my Bro to lend me his laptop so I can copy the files on to my sd card. So wish me luck, he's just come round. I'll know in a couple of hours if it works

It's all gonna be fine

Help needed (stuck in Huawei eRecovery)

I had my P9 Plus (VIE-L09C432 B370) boot unlocked, rooted and running twrp recovery. Wanted to reset everything back before I sell it.
Tried to relock bootloader and flash stock rom. But that did not go well.
I can boot into Android, but lots of apps are missing (file manager, keyboard etc) and I can boot into fastboot.
Tried uploading /sdcard/dload/update.app and hold vol up+down + power. But the update process stops as 5% and the phone reboots.
Any tips on how to get the phone back in order?

Try this: boot into android and restore via huawei desktop software.

HiSuite says my device is incompatible when I try to restore when it's in fastboot. When in Android it says it does not need to restore. But now I'm stuck in a messed up B370 which has not keyboard (only google speech) and is missing lots of other apps as well.
What's the latest firmware that it will let me fully reset to (via vol up+down + power) and using sdcard/dload/?
I tried B360 which seemed to work, but it still came up with the messed up B370.

try to downgrade to marshmallow and then update to nougat, it should fix. I had your same issues and I fixed it flashing the "data_full" part of the firmware, but it was something like 10 months ago and I don't remeber the exact procedure and the files I used. If you downgrade to 6.0 iirc you take your p9+ back to stock settings (locked bootloader) and then you can update it to nougat with official huawei firmware via the updater app on the phone.

Could you provide any information on how to do that? The only firmware I've been able to get the updater past 5% is B360 full. Any other stops at 5% when I do the (vol up+down + power and update.app in /dload).
I've tried:
B160 (Marsmallows, fails at 5%)
B170 (Marsmallows, fails at 5%)
B360 (Nougat -> Goes to 100% and reboots, but device is still B370 with missing apps)
B370 (Nougat, fails at 5%)

Ok, so: download this https://mega.nz/#!wswElLwA!qhafrd_13kW8RjYUEjIXT2lxVEgh1DtjUF-DgzuzqlE
And this https://www.androidfilehost.com/?fid=24533103863142914
Now, put the update.app that you find in the first rar in your dload folder on the SD. It must be the only file in the folder.
Dload your phone (vol+, vol-, power). Do this twice.
Boot your phone and check the serial number, it should be l09c900b300.
Power off the phone, replace the update.app in dload folder with the that you find in the secondo download link.
Dload the phone again and boot it, now you should be on emui 4.1 fw b103 with locked bootloader and valid warranty.
You can update the phone to nougat with stock updater if you want. I'm on mobile, so if the post is bad formatted well, sorry, I'll fix it when I can access a pc.

That's for the C900, I've got a C432. Won't that be an issue?

Files are for c432, mid procedure you get c900 cust which is the generic one.. after you flash the firmware (second file dload) you are back on c432

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
