You need to locate your desired ROM for the P7 variant you have and download it. Make sure you have the stock recovery installed. From the download, copy the dload folder and its contents to the root of your SD card and then do a force update.
ROM sources:

chrome://mega/content/secure.html#!BoUWjASI!PfSWMroeQB-QBAumV92qCaJ_QX6ln0avT3epXDwBm44, extract update.app to sd card/dload folder then try local update... this should work, but if not try force update!

is your phone branded? if yes mybe you have to first debrand in order to avoid problem like missing motion config voices...
otherwhise you first have to flash stock emui recovery and than download b609 fw (and then follow a guide here in xda to have full emui 3 function if you have missing features)
http://forum.xda-developers.com/ascend-p7/general/cwm-flashable-b609-p7-l10-complete-t3004343 a cwm version... read the thread

"""echo Full installation B052 ROM,

My bootloader is unlocked, but I'm sure it will work with locked bootloader.
You need to unlock your bootloader to downgrade to the b052, also for use fastboot, but it's a lower price to can have marshmallow.
And of course you can relock it after,like this your warranty was not void.
I had the 5.1.1 beta b009 and I just installed 6.0 b525 with local update, everything worked fine

-Download the B052 firmware

-You need to have unlocked bootloader.
-You need to have adb drivers installed.
-You have to boot into fastboot mode (Turn off the device > press "Volume - key, Power Key and connect USB cable)
-Extract the files of B052 and copy and past in your adb folder the 'BOOT','CUST','RECOVERY','SYSTEM',and the 'FLASH-ALL' script (just run FLASH-ALL.bat file).
You'll have the B052.
-You'll have balong error, download this file:
https://mega.nz/#!kM4ngRAb!3FIgh6WNgP4NWRfnGoDxisd1wAQk3CBPKdKl8_If-v0

[GUIDE] Get rid of balong bug/get back local update on 6.0/unlock bootloader[ALE-L21]

First of all, what is balong bug?
Balong Bug is when you update to a newer firmware that was not meant for your country, your phone doesn't recognize the correct version of your software(instead of correct version it will show balongc53b311) and you can't do ota update.
So in order to get rid of balong bug, when you update your software to a newer version, in the archive you've downloaded there are 2 folders: one contains the firmware update and one folder named custom or vendor which contains update.app for balong bug.
So all you have to do is to install via local update the update.app from vendor/custom folder.
I've tried to find for as many as possibile versions i could find.
I've made an archive of all vendor folders. Download from here
Here is the list from archive:
B049
B120
B130
B132
B133
B171
B551
Now, in order to get local update back, you'll need to have unlocked bootloader and twrp installed because you'll need to flash an archive.
First, make sure you have installed the correct drivers, then enable usb debugging from developer options(tap 7 times on build number to unlock developer)
To unlock bootloader you'll need to register on huawei then enter your details here.
If you have dual sim,enter your main imei;
After you've done all this you'll have a 10 digit code number, save it.
Now download minimal adb fastboot from here and install it.
Plug the phone into pc, open cmd window in minimal folder(shift + right click -> open new command here), type:
Code:
adb devices
and in return it will show something like
Code:
123213asdsa231 device
. After this type
Code:
adb reboot bootloader
. Now you are in fastboot and here you'll unlock your bootloader by tiping this command:
Code:
fastboot oem unlock yourcode
. If you done all this, now it will show on the bottom Phone Unlocked.
Now you need TWRP from here.
Flash it via fastboot with this command:
Code:
fastboot flash recovery image_name.img
.
Enter twrp, flash this archive.
Now you've got back your local update!.
In order to get back stock recovery, donwload your current firmware version, use huawei extractor to extract recovery.img from update.app and flash it via fastboot with the same command used to flash twrp.
If you have questions, ask here.
Please add the newer B564 to the patch
I'm sorry, but i can't find for b564 ...
hey i tried updating locally on b560, but am stuck at 19% for like half an hour...
Bootloader is now unlocked, fast boot works as i can boot to bootloader but i cant push twrp for some reason.
Edit: fixed, wasn't looking for the correct file to put twrp into.
So i flashed B550 i think which doesn't have Vendor file, how can i get to B551 or one that does, will i need to downgrade first.

No, don't do that.
Download stock b560 and install in with the 3-button method and it'll work. ( if you can't acess the install part, just extract and flash stock recovery from update.app).

if you want to go back from EMUI 4.0 to 3.1 you have to flash this one first
https://depositfiles.com/files/nv9pag8i8
rename to update.app and put it in dload and install it (not for daily use, just for downgrade)
after installing It you can flash any rom you want without losing your IMEI
and if you want to flash stock EMUI 4.0 it will be simpler, just put it in dload and update or you can use adb if you want
