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

Are you rooted and have twrp recovery? If yes, then unroot completely and flash stock recovery...
After that, try updating it again..

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.

P9 Lite EMUI 5 STOCK PLZ!!!

[Current Build - VNS-L31C432B160 Current Number - VNS-L31 Current EMUI - 4.1.1 Android 6]
NEED EMUI 5 or Higher Please!!!
Hey, there would it be possible to get some advice and working links, please.
I spent the day sorting out by P9 Lite that I got off eBay after my P9 got busted.
First up was the FRP - Done (finally)
Then it was the bootloader (trickier) Thank you DC-Unlocker, Huawei call centre no help.....
The phone is now unlocked, TWRP and Rooted.
Now I need to get it on to Stock Rom that supports EMUI 5 before I can install or try most of the custom ROMs on here, the problem is the links that I've come across lead to Huawei official site that no longer works.
I can use B383 but as my phone is dual sim should I not be using B382?

So if anyone could shed some light on my next steps to update the P9 Lite so I can install custom ROM's I would be very grateful.

Hello,
i will suggest you how to try to get emui 5,
but in order to do this you need stock recovery. Check how to HERE.
Check with inbuild updater if an upgrade is offered. If you find no update use Firmware
Finder to force the update. VPN method worked fine for me but i update my firmware when i already was on emui 5.
All infos are inside the app. Your device is dual sim so look for B370 full ota mf pv first and
if you don't suceed go for B370 full ota one... ( firmwares that ends with odd numbers are for single sim ).
Absolutely do not use firmwares ( C440 ) with different version of the region you are on ( C432 ) because of bricks..
How to start:
1 - Check with inbuild updater and if gives no results go to point 2.
2 - Use Firmware Finder to force the update.
3 - If you find a update with inbuild app or FF then stop, don't do it, you need stock recovery first.
Feel free to ask but i can reply 1/2 times in a week and anyway can't assure this.
Good luck !!
Cheers
