Downgrade Huawei P8 GRA-L09 Android 6.0 B317 to B170 Android 5.0 stock - Huawei P8 Guides, News, & Discussion

Hello to all, firstly sorry for my english if there is something wrong.. sorry
I'am one of the user who update my Huawei P8 GRA-L09 to the latest firmware of Marshmallow B317 from B200, after 1 day of usage i'v have a conclusion about Marshmallow B317 :
-. Camera quality is bad now after update to Marshmallow, even if there is an professional setting now,
-. The battery is ok but worst than in Lolipop
-. Transition Page has been modified to something fade "I don't like it " bring it back HUAWEI !
-. From Updater, the option " Local Update " is no more, you can't make Local Update only Wifi
-. and other minor things..
I'v tried all things to downgrade, Rollback to B300 but nothing.. Reset / Restore but nothing.. Remain the same B317 firmware.
And today I have successfully Downgrade to Lolipop 5.0 B170 and here are the steps :
1. Download B200 Rollback, unzip it and put the " dload " folder in the SD Card.
After that : Shut down the Phone, Press Volume UP + Volume Down + Power in the same time and hold until you see the Update. In the Settings you will see the same B317 but is nothing
Download here B200 : http://huawei-info.de/p8-mm-rollback
2. Format your SD Card in android
2. Download B170 Firmware Europe Lolipop 5.0, extract it and put only " dload" folder in SD Card, after that dial *#*#2846579#*#* it will appear a menu with options and select SOFTWARE UPGRADE > SD Card update
Download here B170 Europe Firmware : http://www.carbontesla.com/2015/08/download-huawei-p8-l09-b170-android-5-0-firmware-emui-3-1/
That's it, thank you !

Downgrade from backup?
Hi all, I have tried this metod to downgrade but it says faild. Have stock recovery. So my question is : is it safe to go back to B200 from my twrp backup?

B317 was a little buggy, but still much better than B200.
0. Camera? Its the same.
1. Battery is worst than in Lolipop? Its like 1/3 better, and i have a lot apps.
2. just detail
3. Why do you need local update in settings anyway? I really dubt there will be any other version than Marshmallow, its not nexus, and huawei pretty much sucks at support.
4. Everything is better in Marshmallow, much better UI, much better battery life, much better performance, more stable.
Maybe you should try latest version B321, its perfect.

How I rolled back to lollipop from marshmallow:
1) Goto this webiste: http://www.huawei-info.de/p8-mm-rollback
2) Download these 2 files:
a) GRA-L09 Rollback-Datei
Huawei-Info, 177 MB, Zip
MD5: 9ac71084bb0dd7bf542c41cc4e0004fb
b) Download GRA_L09_Europe_GRA-L09_C432B200 Full Version
Zip, 1,7 GB, Mega
md5: 50bbc81de40ee8ef4038169fd923838b
3) extract the first file (GRA-L09 Rollback-Datei) and copy the folder "dload" to your SD card
4) Enter your Dialer and type in the following: *#*#2846579#*#*
5) This will enter a new menu, Select Option 4: Software Upgrade. Then Select Option 1: SDCard Upgrade. Click OK when prompted
The phone wil reboot and install the first update, wait untill the phone has fully updated and finished. It will now still be on Marshmallow so heres how to downgrade to lollipop
1) Open your SD card and delete the folder dload
2) extract the second downloaded file (Download GRA_L09_Europe_GRA-L09_C432B200 Full Version) and copy the folder "dload" to your SD card
4) Enter your Dialer and type in the following: *#*#2846579#*#*
5) This will enter a new menu like before, Select Option 4: Software Upgrade. Then Select Option 1: SDCard Upgrade. Click OK when prompted
The phone wil reboot and install the second update, wait untill the phone has fully updated and finished. Now you will have to setup your phone all over again as thought it was a new phone. Once you have setup your Region, Wi-Fi and google account then phone will be done and you are now back on Android 5.0.1

I'v just tried and B321 and… one thing is better, a little "battery life" but the camera is AWFULL. I'v tested some pics with Lollipop and Marshmallow from the same posision, angle, it doesn't compare, they must repair fix camera quality on Android 6. ( Try to take shots with Android 6 and Android 5 and pinch to zoom you'll see big differences in terms of quality ) I will wait maybe Huawei will fix Camera or maybe it's too late because is coming Android N.
Right now I'm on B350 Lollipop 5.1.1 and I think it's the best Firmware at this moment.

PS. Next one, this one should show the amount of detail in shot, maybe lolipop had better, but if so, i really didnt notice

re
That's mean to reinstall again Android 6 and take again photos, but take photos from a far landscape not macro, pinch zoom then you will see big differences clarity between Android 6 and Android 5.
Yes I now in the sun every camera take good shots even my old Nokia N82.
These was taken with Android 5 Lollipop and keep in mind I don't take photo outside just like you, so Android 5.1.1 Camera ROCKS !

alright, so today i had to reflash whole MM again, so i had to flash B200 again so i tested camera quality in both of them, and its the same. Both low light condition, same angle, on MM its very clear and very sharp even in zoom, just like B200 sample (after update i did factory reset and wipped cache to be sure its like it should be) :good:

It should work with any marshmallow downgrade, b317 should work too. Remember to remove your cable before starting the process.

I think I have found the reason for this...
Lollipop camera has OIS for both the standard camera & video camera, while in Marshmallow it does not have this for either. So, for the users finding little to no change between the two, they must have very steady hands!

Rollout of CRR-L09C432B361 startet yesterday.
Some Bugfixes, Update EMUI from 4.0 to 4.0.1 and latest Google Security Patches.
Download of OTA available via source: http://www.huaweiblog.de/downloads/huawei-mate-s-b361-firmware-update-ota-download/
Nice to see, Huawei still optimizing their firmwares. After all the buggy ones, this seems to be stable and fast.

Thanks in advance for your reply.

I think you must update it from B321 to B621.
@Feroztex
I did a rollback to B145 because the HiCare App under B321 said the B361 update is available, but the updater had no B361.
After the rollback I installed OTA B177 and then got immediately the B361 Update. So I think you can install it over B177.
I'm in B321 but when i want to upgrade for "*#*#2846579#*#*" it says that it's not archives in dload...and it is (update.zip), i tried upgrade for direct access (Volumen UP + Volumen DOWN + Power Button) but it says that upgrade failed!. Help please :S

Same here - In my case I'm currently on C900B321 instead of C432B321, I think that this is the problem.

Did you place the update.zip in "dload" folder? And "dload" must be in root directory of your SD card.

Same problem here. Currently CRR-L09C432B321 version, not rooted device, and not a company device. :crying:
I've tried these different methods to upgrade:
*#*#2846579#*#*
Installs, but nothing happened. (Updates really fast, so, I think that it is doing nothing and just skips the update).
Volumen UP + Volumen DOWN + Power Button
Upgrade crashes at 5%.
MyCare
No updates available.
Maybe I am doing some step wrong? I just format an micro sd card, create a folder named dload/ on root and paste the "update.zip" inside of it.
Thanks in advance for any help you could provide.

I think I've read here on xda that you can change your region / vendor or whatever to fit it to the right version number. But I haven't done it and I wont, I just removed root because I'm going to sell my phone (I can't stand the fact that there are absolutely no custom roms out there), and afaik you need root to change that file. Just search a bit, you will find something

Hey RonPo do you now have full marshmallow from your B177 update ? as i have read the update . zip is a incremental update and not a full update. B177 was lollipop. so please clarify for me. also the file in your link is 1.05 gb so it would suggest a full update but it says HwOUC.zip . does the file need to be extracted? is there an update . zip or update.app in there?
---------- Post added at 09:24 AM ---------- Previous post was at 09:10 AM ----------
Would anyone be so kind as to upload that file to another mirror other than Mega? Files greater that 1gb have problems to download. i would be greatful.
Hi omniajet.
Yes from B177. Extract the HwOUCH.zip. Get the update.zip (1,113GB) and give it in the dload Folder on the intern SD.
Make a lokal update from the updateprogramm EMUI 3.1
You need a separatly Mega-Plugin for your Browser (Mozilla) for greater than 1GB-Files.
ok thank you just trying it now
So now i seem to be upto date on B361 however i have come across something very strange. my phone is originally a C900 model it came with b300 installed on it . i have since sucessfully upgraded to c432b145, and C432b177 but everytime i go to any sort of marshmallow, it reverts to C900. I rolled back to B300 two times the first i upgraded all the way back to B177 and it was fine showing C432 but when i attempted to put B321 on it. it showed C900b321 on it although i downloaded C432B321.
Now i have again rolled back and upgraded to B177 and now i am showing C900B361. very strange but i will see how i get on with this. thanks for all your help.
PS i used opera for windows to downlaod the mega file hassel free. chrome and the mozilla plugin did not work
You are welcome!
Build number
Does anyone else have the build CRR-L09C469B120? Also does anyone know the region this build is for? Can's seem to find the build number anywhere. sigh
Which countries apart from Germany got OTA update from B321 to B361 so far?

its still 132.... you wont be able to flash sane version of firmware. if it was newer it would be b134 or 141 etc, not 132.
The "new" B132 is rollback update(firmware) to Android 6.0 (Found in changelog). Maybe its little "signal" to us that Android 7.0 (Official) is coming.
Do you have NEM-L21? Then how did you get work NFC? I have NEM-L21C432B132, but I think my device have not NFC (I think L21 has fingerprint, and L51 has NFC but no fingerprint)

theres no nfc, update doesnt change anything. you cant have nfc as theres no nfc chip installed inside phone. you can buy external nfc gadget i think since NEM-L21 has OTG support.
Could it be a roll back from nougat to marshmallow build?

Huawei P9 - Software Update problem

Hi guys,
Good day to all. I just bought an Huawei P9 - EVA-L09C440B138 and i'm having some issues with updating to Nougat.
As far as i understood i need to change from C440 to C432 to get Nougat.
To be honest.... i simply could not find a solution for my problem and i need help from you guys with a guide how to do that.
Can someone give me a solution.
Thank you!
A shot in the dark here, but you can try downloading this ROM:
http://www.carbontesla.com/2016/11/download-huawei-p9-b182-marshmallow-update-europe/
You will also need an SD card (if you already have one, you can use that)
- Once you have done that, extract it anywhere.
- Connect your phone to your PC, allow access so you open your P9 storage from your PC
- Copy the "dload" folder over to your SD card (so you have a folder on your sd card called "dload" with UPDATE.app inside)
- Power off your phone
- Hold down both volume buttons and power button at the same time
It will either go into recovery mode where it installs the firmware EVA-L09C432B182, or fail doing that...
If it manages to install B182, you can just update your phone to android 7 normally from settings. If it fails you probably need a different ROM, but I dunno which.
https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523
One of the top threads for the Huawei P9.
A bit research should have done this.
You will find most needed files in my signature.
I just managed to update from B138 to B142, but i couldn't go to B380.
Please keep in mine that mine is C440 not C432.
I used also Profy Finder and so on.... now i'm stuck to B142, any sugestions ?
Thanks
P9 - EVA-L09C440B142.

Finally.... Downgrade Huawei P9 from Android Nougat to Marshmallow {100% WORK}.

in the last few weeks, my Huawei p9 had many problems cuz of the last update!
my battery drain was increased, also the mobile shutting down when I used the camera even if battery more than 30%.
i thought all of those problems cuz of update not the battery, when I searched many times I found many guys written the same problems!
i contacted Huawei customer services, they told me that Huawei removed all software from their sites cuz of wrong use from some customers
here are how to Rollback your device without any problems.
1) First, download Android Nougat Rollback Package for Huawei P9 from here
middle east http://download-c.huawei.com/download/downloadCenter?downloadId=91646&version=357962&siteCode=kwen
europe http://download-c.huawei.com/download/downloadCenter?downloadId=91727&version=358124&siteCode=nl
2) Now create a folder dload in the root of your SD card and place the update.app file in that folder.
3)Now turn off your device.
4) Now press “Volume Up + Volume Down and Power Button” together. The update process will start automatically.
5) Now wait for some time to complete the process. Your firmware version should now be on “B300”.
6) Now download the full Marshmallow firmware from here
middle east http://huawei-firmware.com/rom/huawei-p9/eva-l19/324
or you can choose your eligible software from here
http://huawei-firmware.com/phone-list/huawei-p9
7) Now move the update.app file in SD card folder (Replace the rollback update.app file).
8) Now again press “Volume Up + Volume Down and Power Button” together to Downgrade Huawei P9 from Android Nougat to Android Marshmallow
9) Done.
This is the complete guide to Downgrade Huawei P9 from Android Nougat to Marshmallow. If you have any questions comment below.
This will be helpful. I have some question.
1. In number 2 do you mean to unzip the files and put the dload folder to sd card and leave update.app untouched?
2. And can you elaborate number 7 please? Is it the same update.app in number 2 and do I need to replace it to the downgrade firmware?
3. And is it okay to downgrade when my phone is currently network locked? Will it affect my phone or should i have it unlocked first? Btw my bootloader is still locked and I have no root.
I love you man! I nearly gave up! Thank you SO MUCH!
PS- Can we update the phone after rolling back? Or Will the OTA updates brick my phone?
It works indeed
Many thanks. It works perfect. Il had to use Hisuite to move the file in dload.
Now I get a notification asking me to update to emui 5. Ik don't want to do so of course but I can't stop the notification. Has somebody an idea ?
Don't understand guy.. am on oreo and never had any problems ..
Hello,
If I do the downgrade, will I lose my pics on my phone ?
Thanks for you feedback.
Reset Netwrok Settings
I was having the same issue ( sudden power-off when using camera or apps that use location), as well as the battery draining very fast.
I followed the steps suggested by Huawei to reset the network and (so far) it apperas to have resolved the issue. TBH its only been two days, but so far its looking good and did not require me to rollback or perform any other intervention. I'm too new to the forum to post a hotlink so you'll have to cut and paste it.

I hope it helps!
Oh god, thank you so much! u did the depression leaves me. I love you man <3

Downgrade From 9.0.0.286

I managed to downgrade from 9.1.0.311 to 9.0.0.286 through HiSuite, but I want to downgrade even further, to EMUI 8.1(preferably 8.1.0.152?) as both EMUI 9 and 9.1 have very poor battery life on performance on my phone. I have the bootloader locked and my model is CLT-L09 C432. Before I updated to EMUI 9.1, I was on 9.0.0.270 and the option "Switch to other version" (EMUI 8.1) was available on HiSuite. Now it isn't on 286.
So, is there any way to downgrade?
Regards,

I'm just in the process of doing the same.
Use DLOAD method to get back to 9.0.0.195, then hisuite will give you the option to roll back to 8. (You'll need a usb-c otg cable) - This wipes the phone, be warned.
Download 9.0.0.195 here:
https://androidhost.ru/T8h
Basic Instructions:
Unzip the package. delete the CLT-LXX that you don't need. (so remove CLT-29 in your case)
copy the files to the SD card. Place the inside a folder called dload. (so you'll have "update_sd.zip" in the dload folder, another folder under dload called "CLT-L09_hw_eu" in which you'll have another zip called "update_sd_CLT-L09_hw_eu.zip"
open phone dialer and dial *#*#2846579#*#* go to Software Update and then select memory card upgrade. (alternatively with the device off press vol UP + DOWN + POWER and hold)
cross fingers and wait while is does it's thing.
Phone should now boot on 9.0.0.195, and hisuite /should/ give you the option to go back to 8.xx.
...You may be able to go back to 8 directly through dload method, but I've done it in two steps to be safe.
Someone else shared these images to help explain better. (Sorry whoever you are, I don't recall where I got this link from!)

Thanks, but do you have that 9.0.0.195 locally by mistake? It seems that on my computer it downloads with 256k/s and it would take 8 hours to download completely.

That's androidhost.ru I'm afraid - it's painfully slow at the best of times Took me about 2 hours to download it from there earlier.
And it did finnaly work, fortunately. Now I am on good old EMUI 8.1 . Now I still have a question, would it be able to disable the system updates app? As there's always the red dot on the settings icon because it keeps telling me I have a EMUI 9.0.0.163 update. And I don't want to update. I turned off auto wifi updates download but I'm afraid to not force update it after some time.
