Rollback L23 - Huawei P9 Lite Questions & Answers

Hi I've a L23 variant of P9 Lite, it officially updated to Nougat (L23C605B363) but it's draining too much battery. I tried factory resetting my phone through setting and button combos but no luck, it still drains too much battery.
So i'd like to know which firmware version should i use to rollback to Marshmallow from Firmware finder.
I don't have bootloader unlocked and don't have root or anything. Its factory SIM Unlocked only.
And I don't know which ROM could work with my variant because I can't find any info on most forums.. I only see about L21 and L31..
Thanks in advance

I'd really like an answer to this... I prefer marshmallow, cuz getting otg and exposed to work on nougat is a task and a risk IMHO. Also my bootloader is unlocked and in the process of installing twrp and root...

NXTL-AL10 Firmware upgrade

Hello, ive been surfing this forum for a while, it helped me to change the firmware of my NXT-AL10 to the international versión, using Fastboot but the versión i was able to install is very old, (NXT-C900B133), it has a few bugs, but at least i got rid of the chinesee software.
Now im trying to update to the new Emui 4.1 the B320 firmware or the newest available, but i allready tried to updated using the dload method, but didnt work, i tried at least 3 diferent firmware version, the only version that i havent tried is the NXT-AL10 – NXT-AL10C00B350 because i believe that it will install again the chinesee version.
Can anyone point me on how to update my NXT-AL10 to the newest international version available without bricking my phone?
i apreciate!
It's supposed to be as easy as flashing the B321 firmware via twrp, just as you would flash any ROM regardless of which variant of the phone you've got. I'm not sure what you're doing wrong here.

Thanks, the truth is that i have technically zero experience with this, it was actually a miracle how i flashed it, i use this thread to find my way to do this: http://forum.xda-developers.com/mate-8/general/howto-load-international-mate-8-t3293619 but i have no idea on how to use twrp.
On the guide that i followed, it was very detailed, it had the download links, and i even had to pay 4 Euro to get my phone bootloader unlocked, but the guide was very explicit.
Now that the booloader is unlocked, and i have a flashed rom, what would be the method, is there a guide like the first one, but with the latest firmware?

p9 lite bricked, i need the b125 full!

I have installed the b161 update nobrand on my vodafone p9 lite, now i can't complete the initial setup, i searched for the vns-l31c02b125 full update, but i found only the ota, someone can help me?
I had the same problem last weekend,
Just install the L31C02B123 and the update to the B125 via OTA.
Downside is that you'll loss root and all. I hope you have a backup.
Regards
Try to flash c432 OEM info.

The safest way to reset and reflash the ROM is dload. You can doald the rollback package and after that the full Android 6 package. Both are available on the official Huawei site
Download Huawei Firmware Finder. You'll see a lot of available firmware. It's official.

Hello dude,
the OEM button greyed it's not a good thing...
If you tried rollback package method again and did not worked,
at your own total risk (maybe you already f***ed up your phone ) you can try this guide...
