1. dl huawei update extractor
2. dl the rom
3. Open These update.app with huawei update extra Tor
4. extract the files......Boot.img cust.img recovery.img recovery2.img system.img and userdata.img
5. enable USB debbuging
6. Go in bootloader and connect it
7. Flash the files

I've tried this,albeit without the userdata.img however although it took me back to EMUI 3.1 and Lollipop some menu items were not working such as setting a screen lock and unable to get to guest mode.
Would also not update using the B114 full ROM, would only accept the B303 beta.

Type fastboot flash boot.........you can put the file in your cmd console (drag&drop) for the path....i dont know why this not work for you
The path is c:\.....where you extracted........ and the update.app must be a full rom not ota update

Ive tried flashing the recovery.img, boot.img, cust.img and system.img from B145, then factory reset and then restoring a TRWP backup of B114 however it still doesn't work, still cannot access lock screen settings (and fingerprint settings) or security settings.

After I flashed the .img files from a b114 ROM I tried restoring my backup however it failed so I had to restore my b303 backup

Rollback
We work here in the German Forum (Android Hilfe) for weeks to find a solution. The rollback is not yet possible.

Try this........DL the Firmware you want anderen extract the Update.app
Flash this IMG Files via fastboot
Boot.img
System.img
Recovery.img
Maybe Recovery 2
Reboot your phone
---------- Post added at 04:36 PM ---------- Previous post was at 04:34 PM ----------
If the settings not work make a factory reset after boot

There is rollback package on polish site: http://consumer.huawei.com/pl/support/mobile-phones/mates-pl-sup.htm
But after I did that it switched do C900.

Hi,
You have to flash stock recovery via ADB. Only image 1 not 2. Than you can easy flash a stock rom via dload Method.
All you need is here:

Hi,
I need help... I'm trying to go back to stock recovery & firmware, I have already tried everything and I'm absolutely fustrated:crying::crying::crying:
1.- I had TWRP recovery and MIUI, the phone (ASCEND P7-L10) is rooted
2.- After downloading flashify and the stock recovery, I have installed the stock recovery, everything OK.
3.- Rebbot into recovery and when I try to wipe data and/or cache it says:
data wipe completed (or cache wipe completed)
huawei cust fail
If I try to install any ROM B120, B126, B133, B135... I always get the same error, "cust fail"
If I reboot the phone still has MIUI... but I need to restore to factory recovery/firmware...
Help needed, I'm going to hit the roof...
thanks in advance!
Put your original firmware on dload in sd card, flash original recovery with fastboot or flashify, shut down your phone. Now press power volume- and volume+ ! This will install the original firmware.

Use only original stock cust.img extracted from stock ROM. I always do it in this order:
1. Download mode and flashing stock recovery
2. Recovery mode and wipe (both option)
3. Download mode and flashing cust.img
4. Recovery mode and wipe (both option)
5. If still error go download mode and flash:
cust.img, cache.img, userdata.img, system.img
6. Recovery mode and wipe (both option)
I had many times this error while reverting my B135 after MIUI ROM.

Well, after flashing again recovery, boot, cust and forcing an update... I get the same fuc**** error, mm... As you have told me, I guess I do not have the right files for my Vodafone Spain P7-L10
I'm going to look for the right firmware, thanks a lot!!!
==== SEVERAL ATTEMPS LATER AND SOME HOURS LATER... SOLVED!!! ====
I've made svarious attemps with diferent ROMs, B126 and B121, while I was downloading original stock ROM from Huawei.
All of these attemps have failed, even flashing cache, userdata and system
But after downloading original stock rom, as soon as I have flashed cust everything started to work perfectly, wipes... firmware...
So, THAAAAANKS A LOOOOOOOT!

hi i have the same problem, if i put my 133 d load in my sd card, the phone go however in twrp...
there is a way to install d load or a firm stock from twrp?
I did it!
I've finally did it!
Huawei has released an official downgrade ROM (B603) here (russian site):
http://download-c.huawei.com/download/downloadCenter?downloadId=38601&version=66144&siteCode=ru
You'll also need this official EMUI 3.0 recovery image:
https://mega.co.nz/#!ZZ9QxIiL!Cn4mV2ZG2zzFc956CoWQh4BnBQqyK4rClghlY8CoXQk
As well as fastboot/ADB (platform tools) files here:
https://www.androidfilehost.com/?fid=9390355257214632011
Now here's how you do it.
Copy the dload folder (found in ROM) to the root of your SD Card
Now turn off your phone
While off press and hold Vol Down & Power Key, when screen turns on release Power Key, but keep holding the Vol Down key until you see a white screen (fastboot mode)
Now decompess files from platform tools to a new folder called ADB on your desktop for example
Hold down Shift and right click on ADB folder on your Desktop and choose "run command windows here", a little black window should pop up
Now type:
fastboot devices - this is to check if your phone is correctly detected (if not, then drivers are needed. Just install HiSuite)
fastboot flash recovery stockEMUI3.0RECOVERY.img
fastboot reboot
Your phone will now boot into your current OS. Go to Settings>Updates>Local Update
This will install the downgrade ROM from russian Huawei site (B603)
After this is installed your phone will boot into your current OS again. This time delete UPDATE.APP from dload folder and put your stock firmware in there.
Now repeat the process Settings>Update>Local Update
This time it will finally install that stock KitKat with EMUI 2.3 OMG !!! Finally !!!
God i hope i'll never have to do this again

[FIX]Marshmallow BOOTLOOP

OK people, so i bring another (hopefuly helpful to someone) exprecience with BOOTLOOP.
Problem: I had stock B200 firmware (5.0.2). I wanted to try beta update of marshmallow, so i decided to try it. It was told me i can update directly from B200 one, so i just copied update.zip to DLOAD folder, went to settings and run local update. The phone restarted, booted into recovery and started flashing. BUT, i forgot that i had custom TWRP recovery and not stock one, anyway, TWRP started flashing the zip, error after error, but some files still copied and bricked the phone. I couldnt start any recovery, just fastboot and some mode that should download online file and reflash system, but it would be very easy so it has error too.
Here is what i did:
1. Download the update zip of marshmallow you were trying to flash and unpack UPDATE.APP
2. Extrac: RECOVERY.img and BOOT.img
3. set phone to fastboot mode and flash extracted BOOT.img, then RECOVERY.img
4. after that, you need somehow copy whole B200 firmware into sdcard / dload folder (i took micro sd and inserted into another phone, then copied it)
5. now you can boot into force flashing mode (power + volume up + volume down buttons) and it automaticaly reflash whole system.
6. after reboot you can use your P8
OK, i got it work!

I think you should put the update.zip in the /dload/ folder
but you need to extract that from the zip, if you open the zip file you will see a dload folder already, just put that at the root of your phone internal storage

Try making sure the MM Beta update you down is just called update.zip and put that in /dload/
then go to settings...update...press menu and select local update....and then you can choose the update you want to apply

Oh yes sorry.
Try placing the original download...named update.zip in /dload/ (don't extract any items from the zip) and then restart device whilst volume + and - is pressed at the same time
Also try a factory reset if you can't get passed boot...do that by pressing volume + when u restart
Also try downloading files again I've had corrupt downloads very often.
Read the threads about extracting boot.IMG, cust.IMG, system.IMG and recovery.IMG from the B145 update.app file using huaweiupdateextractor....it may help

Could you do some small tutorial how to flash via fastboot ? I found this post and i don't know exacly what should i do:
bgx said:
I boot into fastboot and flash via fastboot cust.img, boot.img, recovery.img, system.img, data.img (Hope that I haven't forget something) from the B145 full firmware extracted with huawei extractor.
Then reboot and do a full factory reset with stock recovery.
Reboot and then do the partialupdate B303.
After that again full factory reset.
And then it worked!

As far as I know, you need to go to settings and enable - OEM Unlock....but this option is only available in 5.1.1...its not available in B303 Beta...however it does return in B321 Beta.
However as you cant turn phone on you wont be able to get to settings...so you cant unlock bootloader

https://www.youtube.com/watch?v=-Mhg3hdcSq0
I want to dowgrade from nem-l21_c432b132 back to stock nem-l21_c432b100
I copy the dload and update.app B100 + *#*#2846579#*#* and press update, but is not working, i get update failed.
How can downgrade the firmware?
You got the update fail cause your version is higher than b100.
I think that if you want to downgrade you will have to download Full B100 not the OTA.
But I recommend if you want to do this use the b130 - I am using it and it is very good.
Do the whole procedurę through turned of phone: then VOL down and up together if I remember correctly.
I have try Full B100 not ota.
Not working.
Maybe some one know how to downgrade with fastboot?
nem-l21_c432b132 to nem-l21_c432b130 is working downgrade.
But i want nem-l21_c432b100
i try flashboot
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cust cust.img
fastboot flash system system.img
At fastboot flash system system.img i get failed
someone can help me?
@zzhunt This is an experimental method to go back to B100 by using OEMinfo. You do on your own risk! Required unlocked bootloader and installed TWRP (from Meticulus). Before performing make a full backup in TWRP.
1. Download here this package and put together of firmware B100 on the memory card,
2. Run and install in TWRP this package.
3. When finished install it, restart your smartphone to fastboot mode (Reboot>Bootloader)
4. Plug it into your computer and flash original recovery [LINK] a command "fastboot flash recovery recovery.img"
5. When you can flashed, then disconnect and hold power switch. When the informations will disappear from the display, immediately press the buttons Volume up and Volume down,
6. Will start the flashing system and after finishing restart your smartphone
7. Done!
I tested so far only on my device and don't know, what will happen with smartphone a different serial number/IMEI etc., but rather it should go.

Reverting back can be done by putting the full update in dload folder in sdcard. I have once got that error that u r talking about after the installing process completed. So i simply rebooted. And i got the stock one. So try this, just reboot and see.
@Shubho20 not working

In full stock firmware, after extracting it, there is dload folder. In dload folder there will be 2 folders and update app.
I try B100 firmware bulgaria and greece
On greece is only dload folder and update.app
And in bulgaria is 1 folder hw + update.app
http://postimg.org/image/w6e41dxet/
in hw folder is other folder EU and inside is update_data_hw_eu.app
I try with update.app + this folder.
Not working, at 5% fail install and start normal.
I want to go back to B100 because this updates B130-131-132 is junk for me.
Only problems i have

You have unlocked bootloader? If not, you'll have to unlock - here is a tutorial on how to do it. Then you flash TWRP and perform what I wrote previously.
for me b132 optimized alot battery life and ram usage. also gpu works better.

recovery.img for P9 Plus

Any chance have the original stock ROM VIE-L29C636B130 in their archive? Huawei had removed that already.. and I am stuck in updating my phone as I didn't have a backup of the original rom's recovery file..
Huawei OTA does not pick up any updates and tools I have tried so far failed to apply the full OTA.
restore recovery from recovery2 :
go into twrp
advance -> file manager -> /dev/block/platform/hi_mci.0/by-name/
copy recovery2 to SDcard (or other place)
rename copied recovery2 to recovery
recopy the file to /dev/block/platform/hi_mci.0/by-name/
And after that just reboot? Apologise for the question but I am new in that and I wand to restore my stock rom, recovery, lock the bootloader. For warranty claim purpose ...
Also if anybody has an archive with the firmware file which should be copied to sd and card flashed to my phone ... VIE-L29C185B360
Any help will be highly appreciated.
yes just reboot and the stock recovery must be come back
now to unlock the bootloader you need to install the B181 (download here) but if your current version is B360 you need to rollback to B300 (download here) first then to B181
steps
1- extract "update.app" from the B300 zip to dload folder in SDcard and install it with the 3 buttons methode
2- extract "update.app" from the B181 zip to dload folder in SDcard and install it with the 3 buttons methode
normaly the bootloader must be locked after installation but some factory apps have deleted
to recover this apps you need to unlock your bootloader and flash twrp to recovery2 not recovery (fastboot flash recovery2 twrp.img) then install this zip via twrp, then re-install B181 again
normaly your phone must be in his factory stat
(sorry for bad english)
Many thanks for your help.
My bootloader is already unlocked, on the second paragraph you wanted to say "to lock the bootloader". I am correct?
I will do this as soon as possible and will come back with updates about the status.
A lot of steps, I hope it will go smooth enough for a begginer like me ...
No , after the installation of B181 (step 2)the bootloader will be locked, you need to unlock it again to flash twrp and installa the apps zip then re-install B181 to relock the bootloader (locked stat)
Well, it seems that I am out of luck, when I have arrived at home, the links provided by you I think just stopped working (it was impossible to download the files from work) and I cannot find the files that you are talking about.
Firmware finder is giving me only the files as below. Any chance that at least VIE-L29C185B181 to be the right one? I have attached the picture below.
Corrected: Only the last from your links is working, a 329 Mb file.
all links work for me
you find the files here
http://consumer.huawei.com/eg-en/support/phones/p9-plus/
download :
-P9 Plus Rollback Package (VIE-L29, from Android 7.0 EMUI 5.0 to Android 6.0 EMUI 4.1, C185B300, MiddleEast&Africa)
-P9 Plus Firmware (VIE-L29, Android6.0, EMUI4.1.1, C185B181, MiddleEast&Africa)
Hi, thank you for your patience.
It happened something strange last night, when I have tried to download the files I was redirected to a page where it told me that the connection was refused by server. This happened every time when I tried.
In the morning, magically, the links were valid and everything worked as you said. I do not have a proper explanation about what it happened.
Now, for reasons that I do not know, the download speed is very low, approx. 80kb/s which will give me more than 1 day to download the files (at least the biggest one).
I already started downloading, hopefully all will be ok.
I will keep you informed.
Again, many thanks for your help.
Wait. VIE-L29C636 only have VIE-L29C636B180 not VIE-L29C636B181.

First of all, I have downloaded all the necessary files, but...
Unfortunatelly, I did as above instructions but the phone still has twrp instead of stock recovery. What can I do??
what is your current version?
Vie-l29c185b360
here is the recovery.img from B360 package : Mega
flash it to recovery and recovery2
Thanks.
I have tried to flash it but I have the error:
error: cannot open 'recovery.img'
The file is in the same directory with fastboot and the command is:
fastboot flash recovery recovery.img
---------- Post added at 07:50 PM ---------- Previous post was at 07:19 PM ----------
My mistake, apologise for this. The file was in the same folder, but I was typing the command in another folder.
Now for recovery2 what is the command? I cannot find it anywhere.
fastboot flash recovery2 recovery.img?
---------- Post added at 07:54 PM ---------- Previous post was at 07:50 PM ----------
Another question. In recovery2 shouldn't be the eRecovery?
I am asking this because maybe the guys from customer support/service will check this stuff...
fastboot flash recovery2 recovery.img, yes this is the command
recovery = recovery2 but they boot differently (recovery boot as reset factory or updater , recovery2 boot as eRecovery)

@lockmunk: I do not know how to do it, even for using fastboot and adb commands I have done a lot of research on the web.
@finally, I have flashed recovery.img that you gave me and also checked the phone:
- Volume up + power button pressed -> stock recovery
Now I will try the next step ...
Just another question, how can I boot in recovery2?
