Hello everyone,
I recently upgraded my Huawei Ascend P7-L00 to Lollipop and because of various issues I've been dealing with, I need to downgrade back to KitKat. The problem is, I can't find anywhere the files needed to flash KitKat on the phone. Everything I find is related to L10 or other models, not the L00.
So, how do I downgrade to KitKat?
Phone: Huawei Ascend P7-L00 (L00C17B851)
EMUI 3.1
Thank you in advance,
Elias

Thanks for the reply! Unfortunately, even if the process was succesful, I'm still dealing with the same issues in 5.1.1, like lags, random reboots etc. So I'm looking for an image to go back to KitKat.

after rolling back, you have to flash kitkat rom
here one le latest ( B617 )
Link: B617
Just tried to downgrade to kitkat (B617). I used fastboot to flash recovery/boot/system and it seems to be working. However, to be sure i copied the dload folder with the update.app in it from B617 to the root and tried installing it. This returns an error after some time. Also i find some update OTA B620, but i get an error as well.
E: Failed to sysMapFile '/data/share/0/'
E: Error installing zip file '/data/share/0/'

Well, this is embarrassing but after several months, I'd like to thank you for your help. It worked!
Hello, I'm currently using Huawei P7-L00 (P7-L00C17B851) with EMUI v3.1. I'm facing some problems with the lollipop update. The device turns off randomly and some other problems :-?. I wish to roll-back to the Kitkat firmware. I tried opening the links posted by zaabolla and the links are not working now. Can anyone help me downgrade my device? I tried googling and every thing I found was for P7-l10 not P7-L00. :-/
Thanks in advance and sorry for my bad english.

Hi All,
I am currently running build version EVA-L09C02B123 on my Huawei P9.
This is the stock Vodafone firmware which was on phone when purhased.
I am experiencing issues with lagging/freezing, and unresponsiveness.
Some apps, such as Facebook, also randomly restart for no reason.
After a factory reset the same problems occurs.
I was hoping to download firmware version L09C432B136 and upgrade my device.
Can someone please confirm if it is possible for me simply upgrade my Vodafone firmware to this latest stock version, or will I encounter issues?
Thanks.
Follow these instructions if you want to debrand and still get OTA's: http://forum.xda-developers.com/showthread.php?t=3384903
I came from a C02, now on C432B166. Once I got 166 via OTA, I rooted again. I'll just keep an eye out for any OTA that I might need in future, but so far, so good with 166.

Thanks for the reply. Followed some of the guides on here and now on 166 and seems to be performing much better
Hi everyone!. I purchased my Huawei P9 dual sim (Chinese Version- AL00) 2 weeks ago. I unlocked its bootloader and changed OEM to EVA-AL19C636 and flashed Nougat Beta. Then I reflashed back to EMUI 4.1 (AL19C636B190) but I forgot to flash HUAWEI P9 Rollback Package (EVA-L19, from EMUI5.0+Android7.0 rollback to EMUI4.1+Android 6.0, C900B300). Everything flashed OK, the phone restarted but there is a bootloop at Huawei logo. It cannot be turned off. No recovery,no download mode, cannot force updat, nothing except fastboot. Bootloader is locked again and I cannot unlock it (though I have unlock code). I tried many times but no success. There is always an error:
"FAILED: Remote: Command not allowed"
I can't flash anything using fastboot.
Anybody helps me!. I really need help. Plz!

You have to change the oem.info into Al19 (using SRK tool) then flash Al19 rom.
hi ledinhbac
I experienced the similar issue with you. I rollback to EMUI 4.1 (AL19C636B190) directly from (L19C636B190) by flashing a HUAWEI P9 Rollback Package (EVA-L19, from EMUI5.0+Android7.0 rollback to EMUI4.1+Android 6.0, C900B300) instead of updating to L19C636B361. [ wrong SD card inserted].
My phone restarted but there is a bootloop at Huawei logo. It cannot be turned off. It can only go into fastboot mode. Bootloader is locked and I cannot unlock it (though I havent unlock code). I tried
There is always an error:
"FAILED: Remote: Command not allowed"
Could you solve the above situation?

yes, with dload method. and now i'm want to downgrade to marshmallow again..
Me too. Roolbak erreur
You have to download the rollback package from huawei support, install the update.app from the rollback with the 3 button method, it's around 100mb, or so. Then download the marshmellow firmware, install it with 3 button, then you will have 6.0. You probably won't have the themes, it can be solved with twrp, and flashing the eu (or the region of yours) cust package.
I did that , and now I have c900b170. everything works ok except themes .
if I install EVA-L09C432B136 through dload method, should everything work ok? I will be able to get later the ota nougat update?
Hello everybody!
I can't find any answer in the internet for this question, so I need for your help. I tried proxy method, huawei updater, dload method, but it can't installed the update.
What can I do for install EMUI 5 to my phone?
P.s: Sorry for bad English, I'm a beginner.
dont know what you did with your phone, but for my EVA-L19C432B210 i got update to EVA-L19C432B386 with no problems using standart phone updater.
there can be problems if you unlocked bootloader /rooted your phone, someone say, you never will get updates, but on rooted phone i got updates too.
you can dload method downgrade your version to B136 files here
dont wory that there is EVA-L09, its works for EVA-L19 too, for me it was all my problems solver!
@spatrikwdb
did you manage to update your phone with eva-l19c432b210 to Android 7.0/EMUI 5.0?
Edit: removed.
hi i bought a l09 years ago and tried to root it and use custom firmware
this was not the succes i was counting on, so i rolled back a update.app
this worked fine but i kinda screwed it up, first i had emui 5.0 on it
but i managed to roll a b182 on it with emui 4.1.1,
i don't know how i did it or what my original software was but i can't find any update.app that will update it to 5.0 without an error
if any of you know how i can roll a 5.0 or higher on my phone i would cherish you always

b182 - this is not complete build name
Look into Settings / About and provide the full name/number of your build, like EVA-L09c900b182 or so
If your cust is c900 (as in my example), there are will be no updates
You must rebrand to c432 tpo get Nougat updates
