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 wanted to my phone start over from begining, so I downloaded offical B161 rom, update it to B371 via offical EMUI updater, but I land on "NRD90M test-keys" every fuc**** time, I installed B161, B151... Everywhere I get this dumb ass update, which BTW my mom (has same phone) didn't get and now she's officaly on B381... Any ideas how to skip or whatever this build, so my B161 will update normaly to normal android...? Btw that "NRD90M test-keys" doesn't have anything as offical update, updater is missing, half of the apps is missing, update is only 1.2GB so I'm predicting that DATA-FULL is missing, but still can't update after flashing data full, can't find any updates, I just want my phone to go to normal updating... Btw I tried flashing B381 directy, but it doesn't want to do it, I did flashed OEM-INFO via TWRP, but I'm still getting error with packahe... I downloaded package via Frimware Finder, from original update.huawei...
Thanks for all the help, I appreciate it
Regards
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
Hi everyone!
I just noticed that my P8 Lite ALE-L21C128B130 hasn't been updated since a while and i was wondering why i didn't receive Marshmallow. Turns out my provider does not support P8 Lite anymore hence we didn't receive any OTA. The past two days i've been reading about updating manually and i successfully unlocked my bootloader.
My firmware is ALE-L21C128B130 and i've read on the internet that before the 6.0 update i should put ALE-L21C432B170 on it. I tried it, created a dload folder and put the UPDATE.app in it. Rebooted but i always get the "Software install failed" error and it reboots with the original L21C128B130.
Please help me find a solution for this problem because now i downloaded the third B170 firmware but everytime "Software install failed".
What should i download? Which versions of the firmwares? And do i need to do anything else except putting a dload and selecting "Update from local" in the EMUI menu? I'm putting the dload folder on the internal memory of my phone cause I have a class 4 SD card and i read somewhere that it wont work from that one. My phones internal memory has 2,8GB free space out of 16, could this be the problem? If so what should i delete, cause i checked every folder on it and i just cant find what takes up to 10+GB of storage.
Thanks and cheers from Hungary!

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.
