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.

Are those the correct commands?

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

L31- Brick after downgrade Nougat to MM

Hello !
Last week, i get the nougat beta firmware for my P9Lite (L31)
Today, when i want downgrade to MM, my phone was bricked.
I tried all methods i see on the forum but the phone don't start anymore.
Install via fastboot : FAILED
Install via eRecovery with update.zip : FAILED
TWRP NOUGAT B2 flash : FAILED
If you can help me please, thanks in advance !

unlock bootloader.

I have exactely the same problem, i can't do anything, i have the bootloader unlock, i have acces to TWRP nougat, bug the system don't boot ;( Please help !
I have flash system via fastboot, Failed.
I have no phone now

i also experienced that...this is how i resolved it:
1. Sideload the OEMinfo for VNS-L31 dual sim (or whatever version of P9 Lite you have)
2. Unpack the MM update.zip for the appropriate version of P9 Lite you have.
3. Create a folder on your sdcard called "dload'
4. Put the UPDATE.APP from the unpacked zip file into the dload folder.
5. While phone is switched off, put it into download mode by simultaneously pressing volume up + volume down + power button.
6. Should downgrade to MM.
7. All done!!!
Care must be taken as the OEMinfo is very P9 Lite version specific (ie, Dual sim and single sim).

OEMinfo for VNS-L31 can be found here http://www.htcmania.com/showthread.php?t=1261335
Sideload is a function, rather a command used in adb. Sideload is used to directly flash a zip onto your phone...Simply put the zip file into the adb folder. Thereafter enter TWRP, click on advanced and then click on sideload. Start the adb server and use the command : adb sideload <enter name of zip file here> and hit enter.
Example : adb sideload OEMinfo.zip

Yes, i used it on my phone....Remember, you need to sideload the zip file, using the adb push command will not work.

Did you check if your device is able to connect via adb? use command : adb devices.
You need to install the UPDATE.APP via the three buttons, not the entire zip. It is crucial to flash the OEMinfo. Since you are able to enter TWRP recovery, try flashing the OEMinfo via TWRP.

No conection. Just fastboot mode and twrp. I think the adb sideload not working. The three buttons just show the huawei pticture and stuck on it. Maybe a twrp backup of vendor partition can help, but i don't have one....

p9 lite borked upgrade to emui 5

Hi, I'm seeking help in retruning my p9 lite back to stock rom - I'll try to account for all the steps i've done so far:
P9 lite dual sim but the operator limited it to only using 1 sim, so I used the VNS-L21-L22-L31 Toolkit to fix the problem
Everything went fine until I used the huawei app to upgrade to emui5; After reboot the phone was on build NRD90M test-keys without bluetooth and without any keyboard, only google voice for input.
eRecovery does not work - goes to 5% and gives a error;
I followed the guides to install trwp in an attempt to flash a stock ROM,
issued the following commands:
fastboot oem unlock [the code]
fastboot flash recovery recovery_twrp.img
fastboot reboot
all commands returned without error, but still cant boot into trwp using volume up & power.
Up on reboot, it shows the message saying that my device was unlocked and can't be trusted bla, bla bla and booting now and that's it.
I've tried putting the update.app in the sd card's dload folder but nothing.
Any suggestions?
Thanks

Had the same problem,try installing different versions of twrp,Meticulus one is the only one that worked for me ,so try it

I've tried from both...
the last try was done from adb. Here's the log:
> adb reboot bootloader
>fastboot devices
4TE7N1711000XXXX fastboot
>fastboot flash recovery recovery_twrp.img

OKAY [ 0.640s]

>fastboot reboot
rebooting...
finished. total time: 0.031s
>adb reboot recovery
Then the phone reboots, shows the "You'r device was unlocked and can't be trusted" message and after that "Your device is booting now..." and stays there...
I'm going nuts with this...

Stock ROM to UPDATE IN 2021

Hello, good day. I just wanted to ask, (Im using custom rom now and my old backup is nowhere to be found) If I am going to flash my device to official stock rom, like if I flashed the older version (lets say the MM) can I still update my device today (up to nougat) through OTA update?
i think huawei cloud is the site where we download OTA updates from but I think is already dead.
(sorry if my poiint is confusing, I just really don't know how to explain it clearly)

So if I not mistaken, your build number is VNS-L31C185 EMUI 5 (correct me if I'm wrong).
Firmware finder and Huawei old server are down, so download service ROM.
IMO now you have two possibilities:
A) flash Service ROM using dload method, guide can be found in ReleaseDoc folder. The process will erase all your data and lock the BL again!
B)
- from downloaded ROM extract BOOT.img
RECOVERY.img
SYSTEM.img
CUST.img via 'Huawei update extractor' , follow Guide
(Note: CUST.img on Nougat can be found in the second archive)
- In fastboot mode flash extracted partitions using commands
fastboot flash boot BOOT.img
fastboot flash recovery RECOVERY.img
fastboot flash system SYSTEM.img
fastboot flash cust CUST.img
- fastboot reboot
- Factory reset in stock recovery

Bro try this way out...
Download and install TWRP (if possible) and let me know
Upd.: nevermind, I forgot you don't have an sd card,.
Upd.2.: without SD you can try to flash Service ROM (or B361 firmware) using TWRP and sideload method. Unfortunately, sideload is Greek to me , so google it.

Edit: maybe your data partition is formatted with f2fs (after installing Elite ROM) , it should be ext4. I'm out of ideas bro, sorry.

No problem. I think I hard bricked my phone, I just got boot logo and fastboot but I can't find any fix or solution or anything to do with this.
Flashing recovery or recovery2 finished w/o any errors but I can't boot to recovery.
Thanks for your help by the way. I appreciate it! Kudos and have a nice day. Keep safe.

IMO you only need an SD card and flash the Service ROM.

Updating Huawei P9 Lite h3g/it to Nougat

Hi everyone. I've already rooted my Huawei P9 lite and now I'd like to update it to Android Nougat.
I tried to install different versions of firmware through OTA, but none of them worked out well. I'm starting to think that this is due to the firmware which are not compatible with my device, and considering that my build number is quite uncommon, that could also be the case. I read from some threads that I have to unroot and lock the bootloader again in order to perform the update, but honestly I'm too lazy right now and I'd prefer to keep my device rooted if it's possible.
Does anybody know what could I do in this case?
OEM Build Number: VNS-L31ITAC555B160
OEM Product Model: HUAWEI VNS-L31
Vendor Country: h3g/it

Hi,
you have to rebrand to the Global version (IMO) :
1. install TWRP 3.0.2.0 , Link
2. In TWRP flash C432 oeminfo.zip Link
3. Go back to TWRP's menu without reboot
4. Follow instructions (from step 3.).

Thanks for your help. Is the VNS-L31C432B370 firmware compatible with single sim?

No, that's why I gave you the link to oeminfo dual Sim. If that's a problem for you, try looking for the B371, I didn't find one.

It's not a problem for me. What problems could I encounter if I use a dual sim firmware?

It has no effect on the phone's functionality.
Btw, there's B371 Link ,but it may be password protected . For Single SIM firmware use this Oeminfo.zip

I tried to flash the C432 oeminfo, but after rebooting a black screen with red text appears and I can't unlock my phone because it's unable to decrypt the internal archive. Same thing with the singlesim oem info.
Also I can't mount the Internal Storage from TWRP because it results as 0 MB.
The only way I found to solve this issue is by restoring the original oeminfo from a previous backup.

I've installed the с432b370 update correctly, but I can't flash the data package (update_data_full_VNS-L31_hw_eu.zip).

it happens sometimes...
Just to be sure - reboot to fastboot mode and run command:
fastboot oem get-build-number
and post result.

Okay, now read carefully:
1. Download TWRP for Nougat Link
2. Flash it over eRecovery (!)
using command:
fastboot flash recovery2 twrp3102.img (recovery2 , not recovery!)
3. Flash stock Recovery Nougat
Link use:
fastboot flash recovery xxxxx.img
4. Reboot, when yellow warning appears, press and hold Volume Up for 3-4 seconds, you should boot into TWRP
5. In TWRP select Wipe - Format data - yes - confirm. Go back - Reboot - System
6. And again, after yellow warning Volume Up and reboot TWRP. Now you can try install second .zip file hw_eu.
7. Reboot into Recovery and do factory reset.
Good luck!

Hey, I'm not doubting your instructions! Hahaha.

Restart your phone, if the BL is really unlocked, after restart appears on screen yellow warning. Fastboot sometimes lies...

Okay, finally I flashed TWRP. After restart, I pressed Volume Up key but it remains on the yellow warning screen with the text "Your device is booting now...".
Edit:
I solved this by installing Venus TWRP for P9 lite. Then, I followed all the instructions and updated to B416 through dlaod, and later to B418 through OTA. Additionally, I had to unlock the bootloader again and root.
Now I have a fully-functional P9 lite updated to Android Nougat
