Had my A2017G for a few months, but still stuck on v1.0.0b06 with no available OTA updates.
Will I manually have to flash it to a android 7 version then will I be able to receive OTA?
Any guidance is much appreciated.
It really depends on where your device is from. That build may very well be the most up-to-date build released. Check the ZTE support site to be sure.
If you want to go to nougat right away, I'd suggest manually installing the German update zip / installing the leaked 7.1.1 B01 zip floating around. Afterwards, you'll receive the OTA prompt for the 7.1.1 B02 build.

Yes, you need to download nougat image from ztedevices then push it to SD card and update to nougat will be available via system updater.

I'm in the UK, and had no update since getting the handset.
So I won't need a build 10 to do the update to nougat?
Many thanks

I forgot if it's required. But no harm in doing the updates incrementally. The German support page has the B10 update, as well as the 7.0 update. Then the 7.1.1 B01 leak can be found around here. These of course are all for the A2017G variant.
If you intend to unlock your bootloader, I'd suggest doing so before upgrading to nougat.

Thanks. I'll give that a try when I'm home. Is this becoming stuck on certain software versions common on the A7?
Also in hoping in the future OTA works normally. Apart from this, the phone is solid all-around.
Many thanks
I have one german version... live in argentina, and otas comes really fast... the same day that someone post some info here...
I manually update to 7.0, then manualy to 7.11 b1, then ota notifies me that b02 is relased, so manual update dont break otas...

There is a full 7.1.1 B02 somewhere that you can also use. Just use the MiFlash flasher thing, it shouldn't go bad if you're using the stock flasher

This is the full ota for V1.2.0B01: https://www.androidfilehost.com/?fid=457095661767151720
I'd suggest you manually update to V1.0.0B10 and then to V1.2.0B01.
You can find t he V1.0.0B10 on the ztemobile.de page: http://www.ztemobile.de/support/downloads/?product_id=2100 (Software Update B10)
I'd skip going to Nougat 7.0 first. Just upgrade directly to 7.1.1 with the full ota I posted.
Copy both of the files onto your sd card. They will then appear in the Updater (Settings -> Updates). Just run the upgrade from there.
Be aware! As previously stated by @oleung4 unlock your bootloader before upgrading. I unlocked mine on B06.

It gets more complicated starting with (afaik) V1.0.0B11. If you want the easy way I'd suggest you do it before you upgrade past B10, I would even say do it before upgrading from B06.

I unlocked mine without too much problem from B08 using the windows 1.1.1 toolkit: https://forum.xda-developers.com/axon-7/development/tool-axon7toolkit-t3573108
I did get into a lot of trouble when I relocked it, so just avoid that.
Good luck
I've put the German image file on a USB and connected via an OTG cable, no joy......
I have V.1.0.0B11
If I were you I'll stuck with the latest marshmallow update. Nothing against nougat but MiFavor's version is sucks.

First: Check that you didn't put the zip with the buncha numbers. If you open the zip you should find an update.zip and a pdf or something, and you have to use the update.zip inside. NOT directly the one with the numbers!
Second: Your phone probably won't find the file on the OTG, if so just copy the file from the OTG to the root of the internal storage
Ah....
I unzipped it.....
Okay so still no joy, neither of the files would update
"System Update Failed"
Attached screenshots if anyone can help ??

You almost brick the phone. Tell me a couple of things:
-What's the model? Turn it around and look below the Dolby Atmos symbol, it should be etched there. Either A2017 or G or U.
-I see that your software is of the A2017G. You probably have an A2017.
-What's the version that you downloaded? If it is for another version you can lose the IMEIs.
I have a similar issue. I have an A2017G. I had LOS on and am trying to go back to stock. I can get MM B10 or B11 to load, but N B01 won't flash within Android and if I force it from within recovery, the phone won't boot. anyone any smart ideas?
I see the firmware OTA has been released for A2017G, I'm in the UK and not ever received it, am I going to have to get it from ZTE DE again?

May I ask you whether this australian version work without any issue on any A2017G? if that's the case, can I flash it from marshmallow B08 or do I need to go another route? (like M B10 then N B01 then B02 then B04?).
I am in a similar situation where I'm still stuck on Marshmallow B08 updated through OTA last december and I have been waiting for another OTA since then to no avail (didn't receive B10 or B11)...
Also this australian version seems odd to me, as I understood it the A2017G ROM is developped by ZTE germany, why is this firstly available full image particularly dedicated to australia? that's why I wonder whether there is something special about it. Otherwise I'm not sure whether ZTE germany stated they would be releasing the full image for B04 or if it's only through OTA (which I may never get)
Thank you!

That link isn't the full package Aus update. It's the German FOTA update to B04.
To my knowledge, Aus version works without issue. The only question mark recently was whether it would work with the A2017G sold in Japan, and it apparently worked perfectly fine.
Official instructions on Aus support page are to upgrade to MM B10 as the bare minimum, so I'd recommend that.
You are struck on B08 because your country's development team has not released anything newer, much like most other country specific A2017G dev teams. That also is why Aus released the full update file, as they're jumping straight from B10. Mind you, the G more likely stands for Global than Germany ?.

You can force it via recovery. If you decide to wait, lemme know when you one day receive the OTA!
I don't know why I called this post B02, when it's B04 I want. Has anyone one else successfully downloaded and upgraded by putting on the SD card, and if so do you have the link? This is for the UK model by the way, I guess the European is the same all round?

Thanks for the confirmation, is the only link we have at the beginning of this thread?

You can always use the full B04 zip (2GB+) if you aren't able to get the fota update file to work.
That file can be found in the other link I posted in this thread.
Hi all, I'm a US user with W09 and would like to get it to Nougat - I have read the entire "Update to EMUI 5.0" thread and there appeared to be several possible routes, but most were regarding the European version.
I have a US Wi-Fi model and have no allegiance in keeping it a US one, if there's a way to remove the regional aspect to gain access to the update (BETA or otherwise).
I would greatly appreciate if someone who has some experience with or is very confident of the correct path would shed some light for me.
Thank you!

I've just finished reading the entire thread linked above that mentions that method a number of times, so I'm certainly familiar with it, but haven't tried it because sprinkled throughout that thread are plenty of issues encountered. Also, there's no mention of US hardware/firmware specific instructions.
I'm on W09 as mentioned in the OP - thanks for the reply!

I'm away from my tablet at the moment but will do later on when I get home.
We will see after that what we can do. I have updated my tablet to Nougat, but I have BTV-DL09 (4G European version).
To change region I think you have to unlock bootloader.

What's the advantage to switching from US to EU roms? I unlocked, rooted, enabled 5ghz band for wifi, and now only need nougurt but much like the original poster not sure the best route.

The advantage of removing the US stock rom is that the European one has a beta available that is very stable. My thread is seeking someone who's confident of the steps to 1st going European & 2nd installing nougat once there, as there was some debate of complexity to doing even that.
I've been through exactly what you are wanting to do @dutchdoggs54 . Unfortunately I can't tell you step by step how I got to where I'm at.
I was on W09128BXXX out of the box . Read the topic that you have linked in your first post and decided to do it using firmware finder to force the update to Nougat as they described. It actually went very well and Nougat worked great with the exception of Bluetooth not working.
I have to say during the upgrade when it booted into recovery and it was TWRP I was concerned. Believe it had an error but it worked and replaced TWRP as I recall with a stock recovery.
So after all that I decided I wanted my tablet branded as a BTV-W09C100B006. Below is the topic where a member thought they bricked their tablet.
https://forum.xda-developers.com/mediapad-m3/how-to/bricked-m3-btv-w09-t3612699
They were given directions to download the Full update package for the version I just mentioned.
This member got their tablet working again and in the process found that 5Ghz wifi is enabled on C100B006 by default.
That was the main reason I rooted my tablet.
I followed the directions knowing I force install a different version of Nougat from your link.
Downloaded the full version software and dropped it in the dload folder on my US tablet and did the upgrade.
Tablet rebooted and shortly after it rebooted again going to recovery (I tried may times to boot). Don't recall the error but after I unlocked my bootloader again it reset the tablet and I was able to access it again. I did relock the bootloader so I can see updates without any problems after that.
In the end I got what I was after. My tablet shows as a BTV-W09C100B006 and can check for updates.
5Ghz wifi is enabled by default. As I said I relocked the bootloader so I'm not rooted. Overall it's works so well I'll wait for Nougat to get released and then do the official upgrade. After the scare of booting to recovery it was worth every nervous minute of it.
Try to talk to OP from this thread:
https://forum.xda-developers.com/p9/...-root-t3374068
Maybe he can make this app available to Mediapad M3, then changing OEMINFO will be easy.
I posted a question there.
No luck
Ok, so I tried following @Samavb's great instructions and guidance in the other thread last night. Made it all the way to the point where he says to install 009 from the Huawei website - got it downloaded and loaded up on the tablet only to find that it wouldn't install because the 009 file on the website is BTV-DL09 not the BTV-W09 version a US tablet would need.
So I got frustrated and tried installing the B301 build that appeared on firmware finder when I was on the W09-006 build...this was nougat and was cool but no keyboard and the play store wouldn't install anything, so I was forced to revert back to 006.
So, long story short, hours of work have confirmed that there doesn't appear to be a way to get a US tablet to fully functional Nougat at the moment. If there was a 009 or 010 build like Samavb mentions for the US model, maybe it would work, but those aren't anywhere to be found - firmware finder, russian site he mentions or otherwise.
So, I'll happily sit on 006 and wait for a US OTA update. That is unless anyone can tell me exactly how to make this US model into a European model.
Same boat as original poster. US w09 on build c128b003. Firmware finder just finds the same version. Anyone know when there might be a us version update released. I thought it was supposed to be may so have been waiting patiently.....but may is over.

In Firmware Finder select the menu in the top left corner. (3 bars)
Right below your model number, select change model and enter BTV-W09C100 and then search.
You should see B301 and it's a full OTA. However, as I understand it this is just a beta/test release.
Only issue I had with it, bluetooth didn't work. Seeing as how I don't use it, didn't bother me.
I highly recommend you fall back to the other topic about forcing the upgrade to Nougat.
Only difference from my tablet and yours. I was on C128B002. I had already rooted and couldn't get that update.
Also US 64gb version here and hoping for an update to Nougat and EM5. Would love to see it!
Huawei have been quite attentive for updates in other markets which is great. Too bad the non-LTE version in US doesn't get the same love.
Buying this tablet was a roll of the dice for me, banking on the hope that Huawei would be attentive to software updates (for all markets) and custom ROMs could serve as back up/enjoyment. This tablet has solid hardware and with another launcher it is decent.
Sadly, my experiment to try out a non-Nexus device without the latest (or close to pure) Android version is coming to an end. The last M3 sold on Swappa went for around $300.

from what i gather. if you're going from MM to Nougat, you need to install the Full OTA. for that, there are 2 files, you will need both of them. from there, i'm not sure.
Where can I find the full firmware version of EMUI 4.1 for the US version? I want to rollback from EMUI 5.0. Thanks.
I found it here, under downloads there's an official rollback package with instructions in english. I also used it to go back to stock after I flashed N from firmware finder and it woked just fine.
http://consumer.huawei.com/it/support/tablets/mediapad-m3-8/
By the way, why are you rolling back? N makes this tablet 10 times better. I'm on M now and I can hardly stand it.

The rollback files are for the BTV-DL09. Are they compatible with the BTV-W09 U.S. Wifi only version?
I am having several issues with Nougat. Bluetooth and Wi-fi are not as stable, I preferred the lower 1900X1200 resolution which doesn't work with Nougat and I have a couple of favorite apps that do not work with Nougat. I also just noticed the navigation button does not work if you have the navigation bar active. With the old version it worked.

Sorry, I thought the us version was also lte like the eu version. In this case I honestly don't know, you could just try and see what happens. I'm pretty sure you can't brick you install a bad package the system won't let you (just like it won't let me install some update packages from firmware finder, I tried).
Also, you could try to contact the official support, in the release notes it says that you can roll back by contacting them.
Wi-Fi and Bluetooth are working fine after doing a factory reset. And forcing 1200x1920 resolution and 320dpi have resolved many of the issues I was having with the update. Apps now display in tablet mode. Dice Player no longer works, but MS Player and BS player work fine. I'm not a fan of the recent apps view in Nougat, but maybe it will grow on me.

I bought today the M3 ,Model number CPN-L09, EMUI 5.1 Android version 7.0 and
I want to go back to marshmallow ,I press and hold Volume Up,Volume Down and power button
after a few moments I get the error << Update failed>>.I follow the instructions putting the update.app on the sd card.The problem comes because my model is CPN and not BTV-DL09?
Any idea?. The build number is CPN-L09C100B012.
Thanks in advance

Hi everyone !
i have many issues and limitations on my ZTE Axon 7 like battery drain and problems to connect with google account, remove or change it etc. Basically I'm not allowed to do anything telling me I dont have admin rights.. I tried already many solutions to sort these issues but none worked. Even if I do a factory reset I will still encounter same issues. I have european version of the phone I'm on build number ZTE A2017GV1.0.0B11, MIFavor UI 4.0, Android 6.0.1, Kernel 3.18.20 and I want to upgrade it to B35 or a much more recent version. The update in the settings is telling me 'software up to date' so cant do it automatically.
Which version would you advise to have the most efficient and less limitative interface (maybe even avoid overlayers from zte) ? could you help me explaning how to choose and do an upgrade with all detailed steps? also I am wondering if any problem with upgrading and my phone doesnt work can I do a factory reset or nothing and do I lose the warranty doing so? I am looking for most simple way to do so (for a newbie)
thanks a lot !
Download the A2017G B08 Nougat ROM, put the update.zip in the root of SD and use the system update app. From that ROM there is a new Nougat B10 update as a precursor to updating to Oreo soon.

B35 is US. You have to use B08 or 09. But yeah, just update to B08
The Nougat V1.2.0B10 just released. You may get it from the ZTE Germany page.
@ko_wei13 is it compatible to update from ZTE A2017G V1.0.0B11 to V1.2.0B10 ? if I download it from the german website can I set any language after update?

Yes, minimum requirement to update to Nougat is V1.0.0B11. So you can download the file and place it under the root directory of your phone storage and the system update will automatically detect it.
For language, there is no issue for you to change it as the ROM is for global, not limit to German.
I flashed it on my G. Had a couple of glitches but mostly ok. They say you should do a major update after a factory reset. I didn't but the glitches were minor and it seems to be working ok now.
thanks worked great !
@yann360,
Hi,
Yeah, you can set most language in your phone. You can upgrade your phone via SD card.
Thanks!
