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.

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?

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
Device: VNS-L21 Europe Hello, before brick I was on new emui 5.0 firmware and I installed nougat twrp recovery by user @BadWolfYe and then I flashed this rom: https://forum.xda-developers.com/huawei-p9lite/development/unofficial-huawei-p9-lite-t3540493 (I was following all instructions) After reboot It was stuck on Phone is booting... And I tried downgrade guide from this thread: https://forum.xda-developers.com/huawei-p9lite/how-to/nougat-official-firmware-t3512932 I flashed oeminfo zip and dloaded update.app but unfornately zip where I get update.app was corrupted..... Now I have only Huawei eRecovery, dload and fastboot but It doesn't allow installing twrp!!! When I dload UPDATE.APP It says Software install failed. Failed to check the update package. Please download the package again. Please help me!!!!!!
EDIT: I found solution to enter in real recovery(TWRP for nougat)
What I did was:
1. Enter in fastboot
2. connect phone to computer
3. open cmd and type: fastboot -i 0x0fce oem unlock xxxxxxxx (replace xxx with your code)
4. accept fastboot unlock
5. And then it magicaly booted into twrp (my phone's fastboot was unlocked before)
Now I am going to flash back emui 5.0
And then downgrade to emui 4.1
And then I will try to install this: https://forum.xda-developers.com/huawei-p9lite/development/unofficial-huawei-p9-lite-t3540493
Later I will update this post and I will write does it suceed or fail.
Edit 2:
I flashed emui 5.0 with dload and UPDATE.APP

I wrote an edit how I repaired my phone
hello, i'm using Huawei P9 Lite VNS-L21. i tried to flash the stock nougat Firmware Which i actually did and it worked flawless! but there was a little problem because there wasn't any Software update option in there, so after that i wanted to downgrade to stock MM. IDK what happened wrong while installing that, my phone got BRICKED. i don't have the Erecovery and twrp either. i cant flash firmware via DLOAD Method. the only thing i have is FASTBOOT mode..
i tried literally everything.. but nothing working..
I sent it to HUAWEI CUSTOMER CARE and they returned it back after a couple of days...
im really very worried because ive been using this phone for like 2 months ... and now im helplesss, If anybody is reading this please help/ assist me out of this..
Hi all,
I messed up pretty bad trying to update to nougat. Current situation is that my bootloader is unlocked, I can access fastboot and stock recovery. Nothing else.
I've tried to change the recovery to twrp via fastboot but I get command not allowed. Attempting to flash a stock marshmallow rom via fastboot returns failed to load: not enough space or failed to load: no error depending on whether I'm trying to flash the update.zip or the extracted system.img.
I've also tried putting the stock rom in a folder called dload on my external sd card and rebooting while holding vol+ and vol-, it starts on 5% completion then fails. It does this even without the stock rom on the sd card.
I've been trying to fix it for hours now with no luck. Am I screwed?
Thanks in advance,
Laura

Use huawei firmware extractor
Use your rom you want to flash
It gives you boot.img cust.img recovery.img and system.img
Flash all the 4 imgs and your phone will reboot normally
But you will lose all your data

Hi,
I tried this and it did not work, I tried specifying the path and moving the imgs around but it wasn't having it. However I managed to get the three buttons method to work!
I'm back to square one but at least my phone isn't broken.
Thanks for your help
Oh, great
Btw you had to install via fastboot all those 4 files
I had your same problem and i managed to restore my phone (losing all my files)
Check bootloader, if still unlocked?? Try lock/unlock and flash with extractor...

Got the same problem.
Fastboot method wont work, and even flash UPDATE:APP with stock recovery wont work. :-/
Any Ideas?

try unlocking bootloader again, not allowed means it's locked, eventhough it says unlocked. then you should be able to flash twrp. and then you can flash oeminfo for stock mm rom, and put the update.app in dload, and then use the 3 button combo
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??
Odoslané z VNS-L21 pomocou Tapatalku
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.
so i had a p8 lite wich i tried rooting and it got stuck in a bootloop.
this worked for me
WARNING: this does delete everything you have (actually that is already gone)
(read all the way before doing anything)
first i set up adb & fastboot on my pc
https://youtu.be/UN7XW4HnFT8
2nd i downloaded stock firmware from huawei site ( you can also get this from rootjunky)
3rd i used HuaweiUpdateExtractor to get the recovery boot system and cust out (out of UPDATE.APP the one from the firmware)
4th i booted my phone into fastboot (i connected my phone to my pc first because otherwise i couldnt get into fastboot mode)
5th u start the command prompt in the adb&fastboot folder and type these commands (if you dont have custom recovery or custom roms you can skip to 5(i think i didnt do those)) :
1 adb devices (if it doesnt find it wait some time or reconnect it it will pop up sometime)
2 fastboot erase cache
3 fastboot flash boot BOOT.img
4 fastboot flash recovery RECOVERY.img
5 fastboot flash system SYSTEM.img
the system .img is too big so it will go in 6 parts and will often fail but just keep trying make sure to wait long enough because maybe it is still busy
6adb reboot
it should start up now.
these steps worked for me also when i did step 2 i could get into Erecovery wich i could before but now i could erase cache and something else and do a factory reset just press erase on everything then continu
