How to comeback to C434 from C900B300. - Huawei P9 Lite Questions & Answers

So I wanted to rollback to android 6 with huawei p9lite C434B336, and used guide that said to change version to C900B300 and than install android 6 with Sd card. So I made a mistake and firstly changed my version and then tryed to put mw on my sd card and it was not big enough(1gb). So now im. Stuck with this c900b300, and I fear that I wont get update to stable version to android .

tnx man
any news for mt-tl10?
Hello!
I'm new on this forum, but I realy like your work! My questions is: I'm now on B511 version of android 6.0; is it possible to update to this version (B522)? Or what would be the proper way to do it? I'm from Slovenia, Europe and my phone is MT7-L09.
Thanks guys!
Are we sure we will not hear this is the beta in a few days?
Sure it's not a beta? If so, what version I have to be to receive the Ota?
Can any one explain if you need to reinstall the device ? will all data be deleted ?
Can also some one explain on what version you need to be on to be able to update ?
I am on B331 currently (L09)
What about tl10?
I don't understand a single word from this german site.Do we need b513 to update with b522? Or it just can be updated from b331? Is this final ota official? Or just another beta build? For sure its for L09\2GB version thats only clear thing in text. Can anyone explain is it better than b513 and is there anything new? Is update menu in settings back?

I agree there is some questions to be answered...
Also more confirmation if this is official and final...
Why I ask this is cause Huawei support around the glob is crap, I would only trust chinese support.
For instance I asked 2 months ago Huawei support in sweden when he thought Marshmallow would be released
he said that it has already been released in some markets... if the confirmation comes from china I trust it but not otherwise
since Huawei only have "fake support " in most countries where they will tell you to please restart your mobile phone and re install the phone etc besides that they do not know a ****

The next final marshmallow update is coming up. This time is the extremely popular Mate 7 with Android 6.0 and 4.0 EMUI. It bears the name:
MT7-L09C432B522
On demand, Huawei has informed us that it is the final version for MM Mate. 7
The series join because both the P8 lite, the Mate S, the P8 and also the honor 7 have been supplied ? from the Far East with the coveted sweetness named Marshmallow (which is incidentally also excellent reintun for the hot cocoa. Huawei adopt because already a lot trouble, even though there are times comes in this context to the prophets of doom. this we hear but studiously and look forward rather than a working device.
The now presented and distributed via OTA update is of course again rolled out in waves. Your can watch the way with your wireless display introduced in about, first very little and in the end, more and more. The duration, the amount of time so that a rollout takes total to complete, until all are supplied is given always different. You should there but so get in the next two weeks. Of course it may be that Huawei first the BETA User supplied and brings the update shaft for rolling only after. Can not say or verify, as we currently know precisely only by a BETA users who we so firmware received update for its mate. 7 Thanks to the context of wool!
You will definitely be the next time the marshmallow update on your Mate 7 (in the branded devices such as Vodafone or Deutsche Telekom can take a little longer). It may of course be that the full version then has more MB than that which is currently provided to the BETA testers via OTA. Our version was approved by the MT7-L09C432B513 installed Coming. This should therefore be a prerequisite. If you can no longer wait or want, then flash your device manually, are but you aware of the dangers. It could be that your device after running bad, or not at all. Never change a running system. ? But as we now already know you, our warnings are you can not stop and you will not be able to leave. but Ok, then start please with here:
data backup
Before you charge ahead secures to any case your data, just what one should always do before an update. If you need to simple instructions, just look at our: Huawei backup - full backup
Furthermore, it should have your Micro SD card at least 8GB memory.
download
The firmware version MT7-L09C432B522 you can look in my mirror MEGA download / download.
installation
Normal method
The downloaded file "update.zip" copy in the to be created / or pre-created "dload" folder and this in turn to the root directory (which is the top level) of your Micro SD card (IMPORTANT! THE UPDATE.ZIP NOT UNZIP! !!)
Tippe following in the phone set string: * # * # 2846579 # * # * and then Switch to "ProjectMenu" -> "Software Upgrade" -> "SDCard Upgrade" and confirm with "OK"
It starts the update process and thereafter start your Mate 7 new
Force update method
The downloaded file "update.zip" copy in the to be created / or pre-created "dload" folder and this in turn to the root directory (which is the top level) of your Micro SD card (IMPORTANT! THE UPDATE.ZIP NOT UNZIP! !!)
Make sure your Mate 7 is turned off and the micro SD card with the "dload" folder is inserted. Now hold the VOLUME UP, VOLUME DOWN button and the POWER button is pressed, until a menu appears. Change the connection to the "Software Upgrade Mode".
The update process will start and your Mate 7 then starts automatically again.
After the successful update of your Mate 7 a manual Factory Reset is recommended.
they also write on the blog " The download, installation and use of the firmware is at your own risk.
We assume no liability for the functionality and compatibility of the software.
Damages on your hardware, we assume no liability.
Also for the correctness of the contents is no liability. The firmware version has not been tested by us. "

maybe this update is not compatible with the Marshmallow beta version ?
This is a update version and not full version so some one really need to clarify which versions that are compatible with this update!
Any chance some one who has it could do a clean twrp backup and maybe put on mega, it would be muchly appreciated.
TIA

Hi everyone, My phone is Mate 7 TL-09 and firmware was B513 till yesterday I've got B522 notification and installed it. I installed Huawei ID and Huawei Cloud app, so I think, maybe, I got OTA update because of that. These two allow you to backup contacts, notes, ... to your Huawei cloud.
Huawei Cloud+ app: https://mega.nz/#!KVNzzaDL!AOVdRCttM27utV7N937zM__GSZxpyNvRjCtu0itQR1wL
Huawei ID app: https://mega.nz/#!3EdS0L4K!U8cBJw1kB-qlvQF838W-id78vFDMKQeKOyJ2_F1bJ_U
Also my B513 firmware was rooted and my phone recovery was twrp 2.8.7 mobopx tool.
In Notification of B522 update it said it's Full version, first it showed me a 1.22 GB File and I got a backup and return and it was 486 MB.
B522 download link: https://mega.nz/#!GRlzxJZS!x_dSYDOIofOQD-NeoIZ8sT2V6SvtgnPfNkMDKtBCt2g
The changes are: some minor bug fixes, "Backup" and "health"app added, still missing local update and a little phone smoother.
For installing of B522, it says your phone should not be rooted so I unroot and installed stock recovery of android 6 using mpbopx tool. Then downloaded and using automatic install and it reset two times and installed without any error. I installed twrp again and "supersu 1.64 pro.zip" helped me to root again. I've created a nandroid backup, upload in progress.

battery drains very fast on b552...100% to 91 % to 5h scree off
Well it would be nice if we could get better information for us normal people and non-hackers and rooters too ?
In fact all people who have waited for final marshmallow version do not care about any of that staff that is why we did not install the beta.
So leet keep all this "root" talk in another thread. The final version seem to be here so lets instead discuss what versions that are compatible with this official update.
I have never got any updates pushed on OTA so I most install this manually

Going from beta 7.0 to full version.

I'm having issues trying to upgrade my firmware.
The beta hands had a weird firmware number hence not upgrading and phone model simply says l29.
I also have no keypad on phone it's voice only and hence finding it impossible to log into google store and get a new keyboard.
I tried to flash via srk tool a newer 7.0 firmware but it didn't take.
Also I don't have twrp as a bootloader so I can't root phone.
Will any firmware go directly over the beta version either emui 4.1 or 5.0
You need to flash data.zip file for your phone after installing nougat dierectly noe u need to rollback to emui 4.1 and all the steps again and install data zip and everything will be fixed
It won't let me roll back well the version I tried did t work. I'm stuck on a beta with only voice keypad.
Model number is displayed as nxt-l29
Build number nrd90m test-keys.
No version I've tried seems to work.

Get stock firmware on your computer, then use huawei extractor to get stock recovery , then put update.app file into dliad folder in sd card , and then flash using three key combination

Upgrade c185b131 to Marshmallow

Hi i have a huawei p8 lite which runs c185b131 firmware version. It seems that huawei didn't release MM for this specific p8 lite version.
Can someone maybe help me in somehow getting MM on it even if I have to force it somehow or convert it cause so far I haven't been able to find anything that really explains it in such a way that I know that it will work.
Thx in advance.
I can see version ALE-L21C185B571 in Huawei Firmware Finder website. Download that and use the dload method. (Extract UPDATE.APP from te .zip and put it in a folder called "dload" in your SD Card. Then you can head to Software update in settings and click local update in the menu) It's from June and probably one will come out again soon. Always keep up with the firmware site. If I remember correctly for Single SIM you download the latest version that ends in an odd number, but you should try the other one too because it's from june instead of may

Zenfone 3 Max - Can u help to solve this?

Hello, guys
Wanting to expand the memory capacity of my Zenfone 3 max (model zc520tl) I've downgrade this to Android 6 because in Android 6 we can use the SD Card as a internal storage and in 7 we can't.
But, when I did this a huge problem happened: The phone can't recognize my SIM Card!
I've searched a lot and in ZenTalks I've found an Asus Moderator telling that what we need to do is update de firware to the latest version (and it's make sense, cause in Android 7 the SIM was working fine.)
So, now is the big problem that I can't solve by myself: I can't update my phone and I tryed so many ways ...
Look, I had downloaded the latest version in ASUS Support site, move this zip to my internal storage, clicked in "prepare to update" and when it reboot to recovery mode, an error saying a think like "This update is for xxx and this device is with MRA58k".
I had downloaded a lot of stock roms for android 7 and it always abort the update in recovery too.
What I want is just solve my problem with SIM Card. If there is a way to solve this on Android 6, please, tell me because it's better then upgrade to android 7 and can't expand my internal storage.
But, if the way is update to android 7, please help me to do this because I can't do this.
Thank's Allot,
Best Regards

I am not entirely sure what you are referring to by binaries and their versions. Problems with simcards usually indicate that something is wrong with your modem. This is usually solved by clean install. Backup all of your data! Go to sammobile and download latest firmware for your phone and your country. Then follow the instructions and flash it with ODIN. I hope it solves you problem
