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 followed the steps that someone advice me. Like above.
"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.

Huawei p9 hardbrick, cannot resolve the problem

Hello mates!
Yesterday I accidentally bricked my phone and I spent ours and ours on this and others forums to find solution but without succes, so here is what was happen:
I was on L21C432B380 firmware, stock, bootloader locked, without root acces. So I tried to flash ROM 7.1.2 AOSP by Meticulus. I followed step by step guide. I succesfully unlocked bootloader using fastboot. Then I flashed TWRP again using fastboot so I can downgrade to EMUI 4.X and that was succesfull also. After that I flashed oem-info using TWRP and flashed stock UPDATE.ZIP using three button method, both succesfully but when phone tried to boots up It shows message "No OS installed".
My entire system and data was deleted, there is no recovery, bootloader is again locked, I have only managed to get into fastboot mode using adb
Every single command I tryed to run in cmd results in this message: "FAILED (remote: Command not allowed)
Somehow I need to install Firmware using fastboot but don't know how cause bootloader is again locked
My knowledge about this things is above average but I cannot "google" the problem
Please help and thanks in adavnce

Hello man,
Dont know why u do that (downgrade to MM)...
Explicitly written for flash AOSP 7.1.2 to be on emui5 (were u was)...
Flashing oem also relocked your bootloader (written ton of times in threads)....
Now using fastboot re-unlock bootloader re-flash TWRP.
If u maked a full backup just use it, otherwise try to follow this guide..

Hope u will resolve.

(Solved) Please!!! XT1680 Bootloader locked: BOOT UP FAILED

To summarize, I have a Moto G5 Plus, with locked bootloader and I decided to update a ROM STOCK and made a simple mistake by forgetting the OEM unlock option in advance in the configuration menu. An error occurred on the way and tried to return to the stock. Now, when the phone boots up, it enters the boot loader (which is locked) and displays a startup error message that states that you must use the Software Repair Wizard.
trying to enter the recovery gives a code:
AP Fastboot Flash Mode [Secure]
Fastboot Reason: UTAG "bootmode" configured as fastboot
failed to validate boot image
ERROR: Failed to pass validation, backup to fastboot
Boot up failed
Is there a known solution or force a recovery to work?
Thanks to all

Hello;
I found the solution, download the latest firmware from your cell phone, download it just unzip the zip and look for the files: gpt.bin and bootloader.img, those 2 ctrl + c and files go to the folder where they downloaded ADB tools and paste the files there , then execute the steps to open command window here and execute the following:
fastboot flash partitiongpt.bin
fastboot bootloader bootloader.img
fastboot reboot-bootloader
and it is ready to install the downloaded rom.
