Thank you

Just downgrade to b136, unlock your bootloader, launch SRKTool : choice 7 / choice 12 / choice 2 and reflash nougat and it's works :o

[Huawei P9 Guides, News, & Discussion] Stormwatch:
At the moment running a non-rooted Vodafone UK branded P9 with version EVA-L09C02B127 can I flash a newer unbranded version on it and can I flash the latest update or do I have to update in steps as there are a few updates between 127 and the latest and will this wipe out my files and as long I make sure it is for L09C02 will this be compatible. Was used to flashing my old samsung but this is a bit different.
[Huawei P9 Guides, News, & Discussion] Mostar088:
If u want to flash a unbranded firmware u first must unbrand your phone with SrkTool Huawei by flashing oeminfo. If u just flash another firmware then C02 you will end up as C900 and you will not recive OTA and some other function will not work. Just flash C02 firmwares, u can go direct to the latest firmware wich is B132 to C02.

in the about section it shows as 3.1 although it doesn't appear to be as I've used emui 3 before and it's nothing like it. It looks more like 4.1 with incorporated N features such as knuckle the middle of the screen and slide to split screen ( I know, very cool) although 3rd party icons are rounded back to "huawei style"

The android version shows as 5.1 although cpu-z says: 7

Hi all,

My phone has the bootloader unlocked, is rooted and TWRP is installed on the EVA-L09C432B136 build.

Regardlless my datas :

How can I flash EMUI-EVA-C900B040SP11 on L09 ? Is there anyone succeed this ? I read some yes but I wonder how in order to avoid any future problems ^^

Via TWRP or via the dload method ?

- If via TWRP :

Can I use th usual cleanup and flashing method ? and reroot ?

- If dload :

Must I unroot and relock my bootloader, and reflash old B136 rom + original bootloader before flashing the update.zip from another version ? or there is another quicker method ?

And there are the last questions :

Wich ROMs in this post are compatible with the L09 ? All or somes ?

Could I reroot the android 7 version ?

What is the difference between EVA**** and EMUI*** files ?

I ask this because I found many awnser from our community but no certitudes about doing this in my case.

I would like to be sure of the mecanism on huawei phones before wiping, and all the possibilities available to me :)

Backup important data first.

1. Create a folder on your SD card called dload.

2. Unzip the update into it.

3. Shut down the phone.
