P8 lite ALE-L21 firmware update

Hey guys, I have been trying to help my friend who owns a P8 lite, to upgrade his firmware because his phone is in a buggy state where the wi-fi doesn't show any network at all, he can only use data..., and any OTA updates fail.
He is currently on ALEL21C22B190 version. First of all when I was searching for europe firmwares, they all had the C432 code, so I have prepared 3 firmwares for this route:
ALE-L21C432B204 -(5.0.1. to be ready to receive Marshmallow)
ALE-L21C432B564 -(Initial Marshmallow firmware)
ALE-L21C432B636 -(Latest Marshmallow firmware)
So my first question is this. If I do the standard SD card Update.APP way of upgrading, will the C22 current version allow me to install the C432 version?
If not I have downloaded this C22 version, (which I couldn't find easily) ALEL21C22B582 for a marshmallow version.
What do you think guys? Am i thinking this correctly? Will the C432 versions work?
And what the hell is wrong with his wi-fi sensor!
Edit: Foundout from here that C22 is for China,Europe apparently, but the lack of C22 downloads intrigues me.

how can i update P9 lite to android 7

hello
how can i update P9 lite to android 7 for firmware VNS-L31C432B161, i tried to do that by the version VNS-L31C432B370 but the device doesn't accept it througth the memory card , kindly i need the suitable rom and the way

Hey man,
one thing surely i can tell you...
You used wrong firmware. The one you tried to flash is for dual sim phone.
You need B371 (for single sim). Look for HWOTA upgrade, use search there is a couple of guide here on GUIDES & NEWS and
OTHER DEVELOPMENT general threads.
All the best

Undo Rollback P9 lite?

About a year ago a did a rollback on my Huawei P9lite from Android 7.0 to 6.0. Now i want to update it back to the latest version available.
The phone won't do it automatically and I also can't find the right package online to do it manually. Does anyone have some advice on how to do this?
The current build is VNS-L31C900B160 (It also used to be C432 for europe instead of C900)
The phone hasn't been tampered with aside from the rollback.
Thanks in advance
Jenson

Update P9 Lite from Android 6 to 7

Hello everyone, I have a P9 Lite which was issued from Vodafone Europe (originally VNS-L21C02B128), and I'd like to update it to Android 7.
Since none of the stock ROMs I tried would pass the verification when updating via the Project Menu, I found and flashed a newer Android 6 which works fine apparently - build number is currently VNS-L21C900B170.
Trouble is all of the newer ROMs are still not working. During the verification phase, it says they are not compatible with the phone.
Any ideas what is the simplest safest way to get to Android 7 ? Thanks for the help.

Have you tried Service ROMs?

- Unlock the bootloader
- on android 6 rebrand to C432 global
- in TWRP install fullOTA-MF-PV VNS-L21C432B370
- then you can upgrade to a higher version by installing a Service ROM via dload method (it will lock your BL again).
The problem is probably with your current build number - the C900 is fake firmware, incomplete or incompatible. I'm afraid you won't be able to unlock the bootloader or rebrand the phone with this build.

Hello Alf, I did try VNS-L21C02B346 but it didn't work, both with the original and the newer ROM. I also tried the "SERVICE Full Repair VNS-L21 C432B381" from here, also with no luck.
The current B170 ROM was labeled as "VNS-L21C432B170" on the site I got it from, but now it shows as C900. This one updated with no problems via the Project Menu upgrade command, the only one to work so far...
I will see later about unlocking the bootloader thanks.

You can't install C432 on C02 and vice versa without changing oeminfo, that's why you now have a C900 region and failed verification.

Thanks but I don't know hot to change oeminfo. Can I use SRK Tool ?
Also is there a free way to unlock the bootloader ? Is it this one ?
Does the phone have to be dissasembled, or is there a software method as well ?
Is dc-unlocker free for phones with android 6 and 7 ?
