Flash c432 oeminfo and b160 update.app

How can I do that?

I had the same problem...
You can use the rollback package from Huawei.
That's what i did this weekend.
For that i use hicare to access to the Huawei forum.
In this page you have the rollback pagage for vns l31 ( for example in french : http://consumer.huawei.com/fr/support/mobile-phones/p9_lite_fr-sup.htm )
Then use the guide (pdf) in the rollback pagage !
For information, you have to flash the rollback (c900b300) and then the mm rom (c432b160).
Then when you are on c432b160, make update only if you have the 1.99gb ota (data full)!

We need more information. Where are you at now? (Bootloop, normal System, nothing at all?) And how did you install the update? (Local, OTA)
Remember, ALWAYS do a full backup before doing anything with your system, especially but not only, if it's not an OTA.
In my case install abort at about 10% and say that; it was because my phone was rooted!
you can solve opening supersu app, there is an option inside for remove and prepare for an other app.
But on the other hand I see your version ends ...160
check in the zip file that you have downloaded ; the pdf contains version you can update from.
In mine it says:
The following versions can be upgraded.
Versions can be upgraded
ALE-L21C432B525
ALE-L21C432B183
ALE-L21C432B171
ALE-L21C432B009
ciao
Bro check if you are using c432 version or c185, if c432 then it won't upgrade because your phone if c185 variant.
I am also running a c185 variant of phone and marshmallow is running awesome i updated from b160 to b524, now waiting for b550 update for this variant

Hello,
While searching for updates for the huawei P9 Lite model VNS-L31C185, i found a new OTA update files, the VNS-L31C185B140, so after download the OTA update ( not the full update ) with about 500MB size et unzip the file, i just found other files inside the zip:
cust.new.dat
cust.patch.dat
cust.transfer.list
system.new.dat
system.patch.dat

So my question is how to install those files because when i try only with the update.app, the version number did not change ( actually i have the VNS-L31C185B130 update ) !
i install full B140 update and it is working
Hello, any link to download the full B140 update? Thanks!

As I understood, C900 is global and you won't ve recieving OTA so you have to download it manually. I'm also on C900 and I had to manually download and update on last two builds.

I've downloaded this one http://forum.xda-developers.com/showthread.php?t=3497516
(Link in the first post)
Make folder "dload" on your SD card and unzip the content there (.app file and folders must be in dload folder itself, not in any sub folder)
Go to dialer and type in *#*#2846579#*#*
Select Software Upgrade > SDcard upgrade
That's it.

The C900 version

Hi, recently I tried to upgrade my P9 lite to Nougat using Firmware Finder app. I downloaded and installed the B361 version but it was all buggy so I decided to do a rollback to MM. After doing the rollback I got a C900B160 version.
Is this C900 version a problem? Should I change it to C423?
Also, why was the B361 Nougat so buggy? Did I do something wrong?

if you flashed rollback package its ok to get that. just put marshmallow CxxxB161 ( Cxxx- means your number C432 C02 etc.. ) then with 3 buttons method flash marshmallow and you are good to go.

I already flashed the MM and it is still a C900 version, I downloaded it from official emui website as I remember.

You need to flash oeminfo and custom.bin from fastboot .( Your bootloade needs to be unlocked. ) You can check huawei tool thread . There you will find what you need)

P9 lite rollback problem

Hello sir
I lost my Bluetooth keyboard and many other apps and setting after rollback Huawei p9 lite by vns l21 c185b300 firmware
Hello,
i bet you flashed wrong package when you update FROM rollback package...
I mean you have to download FULL-OTA correct package size.... it's like 1.7/1.9 gbytes or something similar.. (not the smallest)
Dload method again and see if all working now..:fingers-crossed:
Best regards..
P.S.: firmwares that ends with 0,2,4,6,8 are for dual sim,
firmwares with 1,3,5,7,9 for single sim (example VNS-L21C185B150=dual sim/VNS-L21C185B151=single sim)
