Plzzz help im stuck I want to rollback my huawei p9 lite VNS-L31 where its build number is NRD90M(test keys) to marshmallow 6.0 help don't know what to do . Plz if you can explain step by step what can i do because i'm not good in these things , My bluetooth not workng , there no calculator , no software updater , i am not able to check if got update or not and so on......, im stuck plz help
Well hey.. first download this rollback package from this link:
http://download-c1.huawei.com/download/downloadCenter?downloadId=93645&version=371484&siteCode=np
Extract and move all the files to dload folder on your external SD Card then install it with the 3 button method. If there's no dload folder then create one.
So the phone will reboot and now you can downgrade to any mm rom
Now just download this mm rom from this link:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66015/f1/full/update.zip
And again extract and move the files to dload folder on your sd card.. Install with 3 button method.
Done! Everything should work now!
In case If you don't know what the 3 button method is..lol
•Power the phone off ?
•Just press and hold on POWER + VOLUME UP + VOLUME DOWN buttons
The phone will start installing the rom and that's the 3 button method ?❤
this is not working for me. it says incompatibility with current version and to download the correct version.

Man, you have to do entire procedure: unlock bootloader, install twrp for Nougat and flash oeminfo for your phone. Before that you have to put in dload folder MM firmware (B130/B131),
because after flashing oeminfo phone try to repair firmware from dload folder. If repair do not start, power off phone and power on with 3 keys combination.
Hi All,
I'm having a similar issue as lennie27 however I think I might have strayed down an incorrect path during the process of upgrading to Nougat. My device shipped with VNS-L31C16B120 with no updates available through the stock updater. I tried the Firmware Finder guides which listed options for VNS-L31C169B13x and VNS-L31C432B13x however none of these updates would work, updater would say it's incompatible with current version. I also tried manually downloading the VNS-L31C432B160 firmware and installing that with the 3 button method as well as the EngineerMenu option with the same result (found guides that stated needing to be on B160 or B161 before making the jump to Nougat). Eventually I decided to unlock the bootloader and install Nougat through TWRP and followed the obeygeekupdate-huawei-p9-lite-to-android-7-0-nougat-manually guide (can't post links ) on manually installing Nougat (stupidly never paying attention to the fact that it's a beta build guide). I've installed TWRP to the device again using the P9 Lite Toolkit v0.0.0.11 found here on XDA (used this when on MM however the upgrade seemed to restore the stock recovery) with the idea of downloading the build from the ministryofsolutions huawei-p9-lite-vns-l31-nougat-b371-update-stable-europe page and pushing that to the device instead (however now the device doesn't want to boot into recovery)
Now my only concern is, will this work? I've noticed a bit of commenting going back and forth on the ministryofsolutions site which essentially boiled down to the need for debranding the phone (apparently C19 is MTN South Africa specific and I need to debrand it and get it onto C432 Europe before mucking about with Nougat, but alas to late) which seemed to be something I should have done while on MM still. If I can find a full firmware link for VNS-L31C16B120 can I flash that through TWRP without needing to follow any prerequisite steps? So far nothing that I've tried to flash using the three button method has worked, I'd just like to get back onto an official stable firmware again.
Any advice will be appreciated

you need to install nougat recovery, not the one from the toolkit. then twrp will work and the device will boot.
to go back to 120 you need to install oeminfo, and then the update.app

Thank you for the reply, managed to come right a few hours after posting. Turned out the copy of TWRP that I had on hand was more outdated than I thought, downloaded the newest copy and that worked on the device. Additionally I managed to find a website listing just about every firmware for the phone (Including my original MTN ZA specific variant) so I downloaded that and managed to restore the phone using the three button method. Phone is back to stock now and even the unlocked bootloader nag screen is gone so I'm guessing the bootloader is locked again as well One day when I'm brave enough to attempt this again I'll look at debranding the phone and getting it onto a C432 based ROM before getting it onto Nougat again.
phone bricked
hello guys! im currently on lineage os 14.1 by meticulus, i wanna revert back to stock mm but i cant. i flashed the custom rom from mm using twrp recovery by meticulus, but now i cant even boot into erecovery! can you pls help me!:crying: DLOAD method doesnt work!
Hello everybody,
After upgrading to EMUI 5 in beta, I wanted to upgrade to an official update via the recovery revolution. Only, I make a mistake and I chose to VNS L21 while my P9 lite is in L31.
So here I am blocked with this rom and impossible to make updates, except in hard reset with huwaei extractor. The phone name is now "generic_a15"
Some problems are present:
Can not access developer mode
Can not update via Dload
- no recovery
Any solution will be useful to me because my current rom has a lot of worries, thanks to you!
adb is working?
Hello,
So i got a p9 lite with MM l31-c185 and after upgrade to nougat i got l31-c185b360. Later i wanted to downgrade to MM so i did this:
1. Flashed C432OemInfo-DUALSIM-P9LITE.zip with twrp
2. Installed l31-c432b151 with 3 buttons method
--> worked ok however this version does not upgrade to nougat so i decided to install my old c185. I did this
1. Flashed oem_P9L_meafnaf_L31C185.zip with twrp
2. Tried to install l31c185b360 with 3 buttons method but did not work, tried l31c185b150 and l31c185b380 but did not work. Ssometimes pressing the 3 buttons doesnt even launch the "install update from mem card" wizard. Also it fails saying this is not the right package version
Pleaaaase can you help me. I wanna go back to nougat b360 or just aaany other build :'(
Thanks in advance
Please anyone
You need the oeminfo file for C185 from this thread: https://forum.xda-developers.com/showthread.php?t=3432873
The one you flashed is actually for L21, which is very misleading. Please read the thread above for instructions. You can also download the service firmware for your device to update to Nougat directly.
Good luck.

Hello. I have a p9 lite, VNS-L31, which now mounts a twrp elite as recovery. I would like to find a way to go back to the last official version of the huawei (the B405 if I'm not wrong).
Thanks forward ; )
Use the dload method
Use this, 5 min of work and you will have device back in stock and on Nougat ?

Hi, i have a P9 Lite VNS-L23, the stock ROM was Nougat 6.0 with emui 4.1, long time ago my bootloader was unlocked, that was the way that i could put the TWRP in my phone, i know about the stupid decision of huawei to LOCK contents like ROMs and the Bootloader code.
I was trying to install Nougat, but i can't. After many tryings to install i found the 3 buttons mode, it restored my Stock Recovery, i got installed Nougat but the defaults apps like Calendar, Calc n others aren't installed. The bluetooth function doesn't work. I think it was because my zipped firmware is damaged, the WinRAR shows 2 errors. But... The real problem is, i bought 15 credits (15 eur) in DC-UNLOCKER and i can't unlock my bootloader yet, because the software doesn't recognize the phone in "COM" ports, If someone knows something about this, or people who knows how i can fix this, plz tell me!
I will wait, i need the TWRP.
Thank you!!
