Question 1: Did anyone in Europe get Nougat for the P9 Lite 2GB Version (with the official updater app, of course)
Question 2: How can I downgrade to 6.0, since I am not currently liking the Nougat update (NFC Doesn't work, also, when I use the "+ - Power button" method, it says "Incompatible package" even though the package is compatible, Also the eRecovery doesn't seem to work too)
Thank you.
EDIT 3/14/2017 4:34 PM: P.S. I don't want any shady method that can brick the phone
the first one i dont know, the second one you should download the rollback package, you can find it on xda and via the dload method (3buttons) you install the rollback, the install stock rom of your choice

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.

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!
Hi all,
i own a p9 lite that was on Nougat VNS-L31C432B381 and i decided to rollback to MM. Following Huawei website instructions I downloaded two packages (rollback package and MM) and with 3 buttons method I flash first the rollback package and then MM. All went right and the ROM was stable. After a while of testing (that's why i went to MM), I decided to upgrade to nougat again. From updater it download and install the new android version (1.25 GB). After reboot I noticed that some system app was missing (file manager first). At every reset/factory reset some system app disappear. I repeated the procedure to rollback and upgrade again with the same result. The only way to use the device was to reflash MM and don't upgrade. Here some information I found:
- my starting version was Nougat VNS-L31C432B381
- now I'm on VNS-L31C432B160 (B160 isn't for dual sim? i have the single sim version) stock recovery bootloader locked
- updater try to install VNS-L31C432B370 (instead of B371?)
- if I try upgrade throught updater SN became something like ndr90 test key
- I tried to restore data,syste,vendor,oeminfo ecc.. from backups made with TWRP in Nougat (maybe wahile i was on MM, I'm not sure). It show the correct SN but ROM was still unstable
- I thought to try install full Nougat ROM but i didn't find any package
Can someone help me?
Thank you
The B37x update that the phone automatically finds after rollback doesn't work and will take you to ndr90 test key as you found out B160 is dualsim so you should flash the 161 one. Then use this guide to update through firmwarefinder/proxy https://forum.xda-developers.com/huawei-p9lite/how-to/how-to-b388-nougat-maybe-b381-guide-t3612072
If you want to unlock your bootloader you can also flash B3xx through twrp. If not, the guide above works fine.

Hi Mara-X and thank you for you answer.
After I write the post i found the B161 package and i decided to give it a try. After flash (all ok) I launched updater again and it download the B371. The update went well and now i'm updating at B381 again throught updater. I think, when it was done, i'll factory reset the device for a clean install. So it seems the problem was B160/161 -single/dual version.
Hi.
After reading many threads, I can say I haven't found the answer to my issues, so I wanted to ask you guys for some help with this:
I bought a latin american BTW-W09, and since we haven't received the Nougat update yet, I tried using Firmware Finder and install the American FW (Full OTA C128). I used the "dload" method, but after a few tries I just got to an incomplete install (No working Bluetooth, many system apps missing, including Updater). I panicked, and found a way to rollback to MM, using the European FW (C100).
I'm now on MM (BTV-W09C100B0006) and everytime I try to upgrade to N, I get the same results: Bluetooth is broken and missing system apps.
Keep in mind, I've tried using 3 different methods: HiSuite/Firmware Updater, Firmware Finder/Proxy in the tablet itself and I've even unlocked the bootloader, installed TWRP (Greatslon mod) and flashed the Zip files.
So after all of that...
Is it possible to update using files from another region?
Thanks a lot
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.

As many people asked Huawei if we can install the B121 first and official firmware that was released to Honor 7, ive figured out how to do that becuase every one thought that you just only need that rollback package to "enter" Android 5.0, well it doesnt work like that becuase Huawei said that you need to give youre device to youre local retailer in order to install the first and official firmware, but ive figured it out how it works:
1*.)If you rollback from B396 you will be downgraded to version B300, as you see thats not B121, thats a must if you want to enter step 2, SO
2.)you have to download the B121 firmware: http://www.carbontesla.com/2016/02/download-honor-7-b121-lollipop-emui-3-1-firmware-europe/
3.)then from that B300 firmware that youre using create that dload folder on youre Honor 7 and paste the update.app file (B121) into that folder
4.) hold power,plus,minus volume key the honor logo will appear !!!KEEP PRESSING!!! when this emui logo will appear "veryfing update info" you just wait
5.)Viola you have a B121 system
*Ive tried to install from B396 firmware down to B121 it did not work idk if Huawei is blocking something cause it keeps bootlooping or I try like the 3rd time it starts installing something but then an error appers maybe you can just and ONLY install Android 5.0 (B121) firmware from B300.
*I flashed my device with TWRP repacked the (B121) firmware with Huawei update extractor so that i could grab the recovery.img file to flash with Android SDK in order to install B121 it didnt work
*reflashed the B396 recovery with Android SDK in order to install B121 it also didnt work
*WARNING* You are doing it at youre own risk, I am not responsible for any damages due to bricked phones or broken ones
*REMEMBER* Doing this procedure you have to backup youre pictures/files to computer or use HiSuite.
