how to recover?

Since I lost everything from the boot to the recovery to the system part to anything, i haven't been able to boot the phone;
I can access erecovery but when I try to recover the phone it stops at downloading and then says couldn't connect to servers so that's dead;
I can access TWRP but when I try to flash MM, it returns errors saying that it couldn't mount partitions (Vendor, cust and other...)
I can access fastboot mode. Some people suggested that I should try recovering using dload but the transfert rate to the sd card is taking forever;
Now I extracted everything from update.app using huawei firmware extractor (see http://imgur.com/MWeCCXi ) what should I flash (via fastboot) and in what order?
I would really appreciate the help.

Flashing cust and system returned failes
For cust: (failed remote: partition error)
For syst: (failed remote: sparse flash write failure)

Since I was running nougat before messing up the phone, it had to be System and Boot extracted from the nougat update

By Nougat I assume you mean the file that has been digged out somewhere in the web and that is floating around here in the forums?
Well we all don't really know what this build exactly is, which makes it very hard to reconstruct your errors and give you advice... I would never flash that but okay, that's why we are here
Do you have a TWRP backup that you can restore (and if no, maybe somebody can upload you a clean TWRP restore file)?
Have you tried flashing CM / AICP?

Indeed, the same build that was floating in here.
I was able to resurect my phone from the dead by flashing boot, system and recovery from nougat build then I downgraded to MM untill a more stable release;
Thanks for your support anyway.

Hi there. Earlier I spent a few painful hours in the same boat you were in. I've managed to get back to a fresh install of the Nougat build from this thread, but can't seem the downgrade to MM using the (translated from Spanish) instructions found here (linked from that first thread). How did you manage to get back to MM?
(I should add that I tried to flash boot, system and recovery via fastboot without any success).
Cheers

May god have mercy on your soul.
For the downgrade, I didn't use the b161 directly. I flashed some oeminfo provided in the same folder as the TWRP. Then used b150 ans the three boutons method. Worked like a charm.
Hope it will help you downgrade your phone.

I have the same problem, someone could explain it to me step by step, please

P9 Lite bricked (L31)

Hi, my problem is with the L31,
I've trying to downgrade from Nougat to MM. I saw on the thread this steps and i followed:
"Fastboot flash boot boot.img
Fastboot flash system system.img
Fastboot flash cust cust.img (This one is in the second zip from badwolf nougat download)
Then I flashed badwolfs recovery b2 as that one lets me transfer files from pc to phone and followed instructions from htcmania from here".
The problem is that i didn't reach to downgrade and when i try to reinstall Nougat by TWRP i get this error messages:
" E: Unknow comand (errno) update_huawei-pkg_from_ota_zip: update package from zip failed"
"Updater process ended with error: 7
Error installing zip file '/external_sd/DLoad/Update.zip'
Updating partition details...
...done"
Now my phone stays freeze on the huawei logo and the flashtool doesn't even recognize my device.
Can someone help me with this matter, please?

"I had to first extract the nougat firmware with huawei firmare extractor and flash everything by fastboot
Fastboot flash boot boot.img
Fastboot flash system system.img
Fastboot flash cust cust.img (This one is in the second zip from badwolf nougat download)
Booth files you can find it in this page.
http://forum.xda-developers.com/huawei-p9lite/development/android-nougat-dev-build-huawei-t3488360/page33"
To flash img. i used the file that i attached.
Good luck

so now i restored twrp , i put the update app in sd card and it doesn't want to flash , i'm still trapped in bootloop but i have access to twrp now what to do now ?

I found the old twrp is okey for downgrade,
Just put b161 update.app into sdcard/dload and press volume down + power key.
but flash badwolf's twrp will get stuck in fastboot, though It's not really bricked.

hi, maybe you also have a solution for my problem.
i installed a wrong update via sd card (dload etc.), now my phone is just black no signal nothing. and it seems like a fastboot loop always when i plug into the pc im in fastboot without doing anything
when i try to unlock the bootloader i get "failed command not allowed")
and also when i try to flash the extracted files from update.zip i get the same error ("failed command not allowed")
by the way i didnt active usb debuggin or oem unlocking
please help thank you

Bricked P9 lite L21 SS

Hello I have managed to brick my P9 lite with the nougat rom. I can only access bootloader, the phone is both oem and bootloader unlocked and currently it's on bootloop. I have tried the upgrade with 3 buttons pushed but I can't get the phone to accept the package(put in the dload folder on SDcard) it only shows 'install failed - Incompatibility with current version please download the correct package'. I have also tried the fastboot flash system command it went without errors but the only result is that it no longer bootloops and only shows black screen after the warning that I have unlocked bootloader. So is there anything else I should try? Thanks.

Fastboot??

Try this

@mrmajco
I don't understand what you mean. Could you give me some commands to use? If I flash recovery with fastboot I can't get into the recovery (nougat rom) and if I flash system with fastboot flash system I only see black screen and nothing boots up.
fastboot flash zip gives me FAILED command not allowed.
@zgomot
Well, either I'm really dumb or doing it wrong but once I flash the meticulus recovery with fastboot flash recovery recovery.img nothing really changes and I can't get into the recovery.
To flashing oem info I get FAILED (remote: command not allowed). I will post it here but I doubt it will be of any help.
IMAGE
edit: I really don't know how but I'm in the recovery so I think I will manage to flash the stock image from there and make it work. I will once I resolve the problem or brick it once more Thank you for the link.

If your phone is VNS-L31C432, then try these methods:
1. In bootloader "fastboot boot TWRP_Recovery.img"
this should boot you into twrp without flashing it, from there flash B161_update.zip (which should be in your SD card).
(If that doesn't work, try "fastboot -c "lge.kcal=0|0|0|x" boot TWRP_Recovery.img"
haven't tried this on P9 Lite, but used to work on other phones).
2. If "fastboot flash recovery TWRP_Recovery.img" returns errors, but says bootloader unlocked, try to relock the bootloader and unlock it again.
"fastboot oem lock"
"fastboot oem unlock YOUR_CODE"
then try flashing recovery again.
Maybe also try flashing other recoveries, e.g. TWRP (which is for MM ROMs) or Revolution (which is for N ROMs) or even the stock boot.img.
3. Try the dload method wth B161 and maybe B160 - I know my P9 Lite would only accept B161 via dload, even though B370 and B360 and B130 are for the same model, those builds just wouldn't install this way.
4. Unpack B161 zip so you have update.app, extract from that boot.img, recovery.img and system.img.
Then do:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
Some of these methods might work, some won't but from my two experiences of bricking the P9 Lite, one of the four fixed the issue.
If you don't know where to get the B161 zips, I can post them later.
Also, this is just to get your system to a working and bootable condition. If you want to get back to full-fledged MM, you will also need to install the hw_eu zip after the B161 zip (and maybe do a factory reset after that for the sake of it).
Your apps and files are already gone, so no way to save that. Hope your phone gets back to working order soon enough.

Flash firmweare with fastboot, download ota with firmweare finder, copy update.app on your pc, extract with huawei extract tool boot.img, recovery.img and system.img(put the extracted images in the same folder where is located your fastboot) and flash them with fastboot.
With the phone turned off press vokume - while pluging the usb cable till will start in fastboot mode.
Run fastboot and enter this commands:
- fastboot flash boot boot.img
- fastboot flash recovery recovery.img
- fastboot flash system system.img
- fastboot reboot
and then wait the phone to reboot.

Thanks m ArluS but it does not work, the flash way around the terminal but upon reboot goes into eRecovery screen and not in, looking obviously some package for download via wifi but hangs failed ... giving me ideas?

I will share a way I got erecovery to work. I was brave and do not recommend this. If bricked do not blame me. I formatted system. Once system was gone it worked.

How do you format the system and restore with a different firmware?

Formatted in fastboot then went erecovery.
