Hello I have P9 lite with L31C432B161 firmware installe (the mobile is dual sim but it works correctly).
The proble is that is impossible to install any other firmware (i tried with firmware finder and i checked before the compatibility for example with the L31C432B371 and L31C432B370).
After dowload and reboot i receive always the same message.
Software Install Failed!
Failed to check the update package.
Please download the package again
May I try using the dload method? Any suggestion?
Many thanks

Hey guys,
I have a huawei P8 gra-l09 v100r001c576b161
I tried to TRWP it and something went wrong.
I get:
Error!
Func NO : 10 (boot image)
Error NO : 2 (load failed!)
Any help would be appreciated!
C576 would indicate an Israel region firmware.
Did you unlock the bootloader before attempting to install TWRP? What version of TWRP did you use? Where did you download it from?
Similar problem HERE (P8 Lite), which was solved by the op by flashing the original(?) firmware - view posts #6 & #13.
Download link here for C576B161 (download the correct one & only use a C576 build for this - not what the op used as his was meant for a different phone & region): http://huaweidevices.ru/category/huawei-p8-gra-l09. Once downloaded, unzip to Update.app.
If that doesn't work, try solution in post #16 of above thread - i.e. flashing those individual files one at a time after extracting them using Huawei Extractor. Then rebooting, & finally flashing the Update.app file only. Use same firmware file you downloaded above.
If above doesn't work either, try similar solution here: [GUIDE] How to unbrick HUAWEI P8 when failed to update and ends in bootloop. I couldn't find a firmware just previous to your B161 (as required there), so you'll need to make do with B161.
---------------------------------
Btw, if you cannot get TWRP to install & work correctly, you may first need to update to Marshmallow (Android v6) - you currently have Lollipop (Android v5). If there is no Marshmallow update for your region's version, it might be possible to change to a European rom (C432), which receives regular updates. Then, if successful, you can follow this guide to install TWRP: [Guide][Huawei P8] TWRP + Root Systemless Marshmallow Installation (GRA-L09 & GRA-UL00)
Thank you very much! You saved me!
Hopefully now I will be able to be careful and upgrade to Marshmallow!
Good morning from Athens greece.
I have P9 Lite L21 single sim.
I was in C900B170 rom and i tried to upgrade to B371 . I tried through firmware finder , selecting the B371 1,99 package. At the first time i didnt noticed that even if i selected the correct package (FullOTE-MV-PV) , when i sent it to the System upgrade programe, it sent only a 1,24GB package. I did the upgrade and i ended up in NRD90M testkeys missing lots of system core applications.
i rolled back to B160 but everythime i usee the "Firmware Finder", it keeps forwarding only 1,24GB package to System Update and not the whole 1,99 2-files package.
Any solution ?
Do one after the other perhaps?
please delete, wrong thread
If he is a new user, he cannot reply in the P9 Lite ROM Thread.
I am on VNS-L21C432B336 (beta) and i'm unable to install B370 via FF proxy. After downloading, it fails verification with error "failed to authenticate the package....will be deleted".
I can't post in the P9 Lite thread, so i am trying here, if someone can help me.
Do i need to downgrade to MM, B160? Cam i update to 370 via dload folder and 3 buttons method without downgrading?
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.
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 everybody,I have a question :
My P9 Lite (VNS-L31 C432B380)is asking me for B388 update.
I rooted my phone using OldDroid's TWRP 3.1.1-1,and official TWRP.
I know i need the stock recovery to be able to install update from settings.So,i googled a bit,and impossible to find the B380 firmware (my Idea was to extract the recovery from it using Huawei extractor).Then i remembered Firmware finder,and I looked for the B380 inside the App.There I see 2 entries for B380,OTA-MF (290MB) and FULL-OTA-MF (1,6GB).
From which one Can i extract the stock recovery safely with Huawei extractor ?
Thanks in advance !
P.S : if there's others ways to update than unrooting,reflashing stock recovery,installing update and then reroot,please tell me !

The way I did it is by downloading the FULL update (it's 2go) an update extractor(found in this forum) extracting the recovery from the update app... Flashing it using adb... Updating normally (make a save of the 2go update and remember the directory just in case to avoid having to dl it again) the reflash twrp and root!!

The biggest package I can found on FF is 1.601GB where did you find your 2Go one ?
EDIT : downloading the fullOTA-mf package gave me a 2.51GB update.app file. update extractor sees recovery.img and recovery2.img,which one do I have to take ?
