Hello,
If there would be anybody who could help me in my problem I would be very grateful!
I was a happy nougat b.09 user when I tried to upgrade the phone to newest android, I installed Oreo B.04 and the phone got much slower, now tends to stutter on web browser and the battery life jumps like crazy. I went on for few weeks but now I can't take it anymore, I want to downgrade to Nougat, probably to B.12, but when I put either N-b.12 or N-FOTA-B10 to B12 from the download center thread into my sd card and rename it to update.zip, the phone still doesnt see it and I cant downgrade.
Is there a safe way to downgrade phone without root or risk of loosing data?
Btw. when I was upgrading the system few weeks ago i went form Nougat.b09 to nougat.b12 then oreo.b02, then unfortunately i downloaded nougatb.04 (mistaken it for oreo) and downgraded phone to it, repeated the process to get oreo.b04 - maybe this process made my phone slower? (but seems unlikely).
The accidental downgrade to N B04 is likely the big issue.
I would try flashing oreo B02, factory reset then flash the downgrade version of Nougat B12, not the regular one but this may actually be a case of needing an ADB connection or similar to reflash it with correct partitioning so I will defer to more experienced modders on this.
If you are on B04 Oreo right now, download the B12 package from a official ZTE source (ZTE Australia has the link for it). Same thing, rename to update.zip and put it in root for SD. If phone still doesn't detect, boot to recovery (power+volume up button), select the wipe/erase all data option first, select yes. After that, select Apply update from SD card then select the update.zip. package. Probably do another data and cache wipe just in case after its installed

Just got my Axon 7, shipped from DE to UK, thought I'd try manual software update.
Current version listed as ZTE A2017GV1.0.0B06
It times out with Network Unavailable despite the fact it is connected to WiFi and Chrome works fine as well as everything else needing internet connections.
I am on Three UK, haven't tried updating without a SIM ... is that worth trying? I did see at initial setup I was prompted to accept some sort of 3UK profile though I assumed this is just APN/MMS stuff.
Anyone else having similar problem trying to update?
I see talk of updating to B08 etc, from 2017G --- is 2017G same as 2017GV1... wouldn't want to assume anything this early on in my game
TIA for any tips/advice.
Am really liking this phone though, might be nice to get latest update for security mainly, not sure if many features are added?
Same issue here as it happens, though I'm currently trying to update WITHOUT a sim (didn't appreciate it was nano so new one on order!).
I was thinking it maybe needed one to be present to update, but clearly that's not the case.

Can't speak to the EU version, but I was surprised when my A2017U would not complete initial setup (& update) without the SIM, although wifi was strong. All completed quickly as soon as I popped in the SIM.
Hi,
I have the same issue here.
I've just bought A2017G from Italy (Amazon) and I live in France. Can't have the upade to B08. There is always this message "No network" after a minute of searching. I tried with 4G and Wifi and there is the same issue!
Also can't connect
Same issue here. I am already on B.08 and have wifi/Sim in place.
Mysterious problem
I have tried many solutions but I wasn't able to update :
- used three different sim cards from 3 operators
- removed sim card and worked only on wifi
- used VPN
- tried to update via SD card form the update page and from recovery
... Unsuccessful !
Anyone have idea?
I'm also having the same problem. I live in Sweden and I just got the phone today. Would be nice if I could update sometime soon.
A2017g b06
Greenland here, I also have problems with the connectivity
Maybe ZTE is updating its servers so that the updates can finally deploy at the same time, the same version, for everyone.
Or, maybe... they are silently getting rid of Adups and moving to another kind of upload process, before **** hits the proverbial fan.
Also, Global Axon 7 here, brought via Amazon.es, sent from Germany and now used across Portugal/Spain. Running 0B08.

I can understand that, but even if we put the B08 update file downloaded from ZTE support in SD card, the update can't be processed.
Hello, I had the same problem, I reinitialized the Axon 7, and I copied the file update.zip B09 on the phone, it recognized and installed the file (I was on the b08 before)
Hallo, i have the same problem with update, I have B06, somebody can give me a link to download the latest firmware and how to install it.

hmm I put a b09 in the sd card and it updated no problem
Solution found!
I’ve already found the solution for the manual upadate from SD card and it’s easy to do.
Theses instructions are not mine and I’m not responsible of what you do with your phone. I found them inside the update file that I Downloaded then I unzipped.
You will find a PDF document called “ZTE A2017G Upgrade Guide (through an SD Card).pdf”. You can use it to do the upgrade step by step.
Till now, all was OKEY: backup is very quickly with Zte app. The update take about 5 minutes, than the phone restarts automatically.
If you cannot find the B08 update file, try to download it from here: http://www.ztedevice.com/support/detail?id=98CEB24F9FFD433EA99EC424163149A6
Here are the steps (exactly as mentioned in ZTE Upgrade Guide)
ZTE V7 Upgrade Guide (Through an SD Card)
1. Backing Up the Data
1) Download the upgrade package.
Open http://www.ztedevice.com.cn/support and download the upgrade package (update.zip) that matches your phone model. If the downloaded package is not update.zip, unzip the package to obtain update.zip.
Ensure that your micro SD card is at least 3GB.
2) Remove the SIM card before the upgrade. Back up the data and APPs in your phone by using the built-in Backup function. To enable the built-in Backup function of your phone (an SD card must be inserted), select
Backup and Restore from the main menu。
3) Perform data backup.
Note:
You should not remove the SD card during the backup process. To avoid data lost, it is not recommended to cancel the backup process.
4) Verify that the update.zip file in the root directory of the SD card
matches the model of the phone. Do not modify the file name and extension name of the files in the upgrade package.
5) Verify that your phone has enough (at least 30%) power. Charge the phone if required. To avoid data lost or upgrade failure, it is not recommended to upgrade your phone through an SD card when the phone is being charged.
Note:
You should not perform any other operation on the phone during the upgrade process. To avoid upgrade failure, do not forcibly remove the battery.
A normal upgrade should be completed in 2-3 minutes. If the phone does not reboot or show any response in three minutes, you should perform the upgrade process again. If the phone cannot be started, perform a forced upgrade. If the forced upgrade does not work, you should contact an after-sale service agent for support.
2. Upgrade Description
There are two upgrade methods: normal upgrade and forced upgrade.
If the phone cannot be started properly, for example, the phone cannot be started, or the phone does not enter stand-by state, perform a forced upgrade. If the phone can be started properly and the Settings menu can be selected, perform a normal upgrade.
3. Upgrade Steps
A. Normal upgrade (the primary upgrade method)
1) Download the upgrade package that matches the phone model from ZTE official website (http://www.ztedevice.com.cn/support/), extract update.zip from the package, and copy update.zip to the root directory of the SD card (the file name must be update.zip
2) Select System Manager > File Manager> SD Card from the main menu, and verify that the update.zip file in the root directory of the SD card is proper.
3) Tap the main screen is displayed. Tap and select SETTINGS >All setting > Updates>,
4) Click INSTALL, The phone automatically powers off and reboots. the SD
card upgrade screen is displayed,
After the phone is upgraded, it is rebooted again. After the phone starts properly, it is recommended to manually restore the phone to its original factory default settings. The phone is upgraded properly and can be used.
B. Forced upgrade (for the phones that cannot be started or the phones that cannot enter standby state)
1) For a powered-off phone, press and hold both the volume key + and power
key to enter into Recovery mode.
2) Press the volume key - to select apply update from sdcard, and press the power key to confirm it.
3) Press the volume key - to select the update.zip file, and press the power key to confirm it. The phone completes the upgrade process in about three minutes.
4) On the Upgrade Complete screen, select reboot system now and press the power key to confirm it.
4. (Optional) Restoring the Data
If you have backed up data before upgrading your phone, restore the data.
1) Backup and Restore important user information.
2) Perform data restoration.
Note:
Do not remove the SD card during the restoration process. To avoid data lost, it is not recommended to cancel the restoration process.

The file is on ztedevice (link in thread) but i think (as some of other users) that this patch is only for Spain - don't know that for 100% but most ppl that can upadate it with OTA are located in Spain. Also I still get "network unavailable" when I trying to check update (location Poland, phone from UK). But you should can update from B06 to B08 as I can without any doubts via OTA.

Here the problem is solved, this morning the ota update worked en now he is installing B08.
I downloaded B09 en wanted to go install it and than the give me the original B08 update in the screen, let see how it works.
As for 1.01.2017 update check start working for me - no more "network unavailable" just "up to date" at B08 a2017g.
Since I'm experiencing a lot of glitches with Android 7, I want to downgrade my phone to android 6 B10, hoping this will stop malfunctioning.
I downloaded the update B10 from the ZTE website and placed it on my sd card.
System Update finds the update, if I press update, will this downgrade my phone without bricking my device?
I know I will lose my internal memory but will I keep my EMEI info and sd card memory?
It won t harm your phone. It will just downgrade.

If fully stock, I don't think you'll be able to downgrade to MM. Lemme know if you are successful though!

You can downgrade without problems. I've done it a few times already (from 7.1.1 b01). I'm full stock, locked bl and unrooted.
I downgraded today, not without problems. It rebooted fine, than went back to the Axon screen, vibrating sometimes, so it was some sort of bootloop. I went into recovery mode and did a factory reset. After, it restarted and worked fine, I'm now back on android 6 with a factory reset, unfortunately, for me, problems from Nougat update still persist.

Which problems?
Anyone managed to do this downgrade successfully with stock rom not rooted? I dont have my country language to choose after latest nougat update.
Edit:
I managed to downgrade to b10 V1.0. Because of the Nougat update I was not able to update via external SD card although my card was 64GB.
I unzipped the file and placed it to root of internal SD. Did the normal update via settings and all went fine until it started to boot.
Somehow it asked password which I thought it was normal unlock code which i had placed previously, it wasn't.
Factory reset via recovery cleared that problem. All running normally now with marshmallow...
There is not much experts here to just to compare op3 Devs..

Hey.
Bought my A2017G from Italy and am in the UK trying to work out how to update it to 7.1.1.
I upgraded it from marshmallow via a manual update but now the build is A2017GV1.1.0B01 and all the sites with the latest update say I need B11 to upgrade to the B05 Spanish June release.
I have had a few niggles with the phone such as I call someone and they can't hear me and hang up. Internet reception isn't great on giff gaff o2 either.
I'm sort of hoping an update might solve these issues.
My phone is not rooted as I want to keep my 2 year warranty. I've contacted ZTE Europe on Facebook but they are not replying.
Does anyone know if I can flash the B05 Spanish 7.1.1 directly over my b01 or not?
I thought I'd take the phone out the box and it will would just get the ota updates.
You should be able to just flash the B05 with Updater or in stock recovery.
Just download the full B05 ROM and unzip to root directory of your internal storage or SD card. Then open the system update and it should detect the ROM right away.
Want to upgrade. Still in original situation as OP - advice?
Re OP. I realise this is a year old now and maybe this is called bumping (I don't know) but I'm still in nougat 7.0 B01.
After I wrote OP, I got sidetracked with life (mother of toddler and no time to decode cryptic advanced phone stuff anymore) lucky if i get a hot cup of tea! ?
Now I'm still suffering from calls where person other end can't hear me when i call them till i turn speaker phone on and off and on. Phone is slow too and battery not great. Have never had an OTA update (in UK.)
If I get any time ever I need a super clear process I can follow.
So. Do I need to
A/ back up all my internal data
B/ make sure battery fully charged
C/ Can I then just download the latest 7.1.1 b10 firmware and install it over my 7.0 b01? Or, do I need to go through each update first e.g. b02, b03, b04 etc etc? How do I know a firmware is the full file not an update?
D/ Can I send my IMEI to ZTE to apply for OTA updates and if so who do I email? Exactly like for the UK?
Sorry for sounding dumb but I really just don't have the time to learn it figure this stuff out and I've read so many threads tonight on here but no one seems to have my ancient firmware still.
Thanks for replying in advance ?

Literally charge it, download the full Nougat B10 update file (update.zip of 2.7Gb), put it in the root of an SD card or internal storage (prefer SD), go to settings/system update and the app will see the update file. Go from there. No need to go up in steps when already on a Nougat system. Always good to back up but these updates preserve user data provided it all goes smooth.
ZTE won't help you at all. Don't need to do anything with the IMEI. People can lose their number when flashing the wrong things but what you're doing is just a standard update. The main thing is, if you have a US, Chinese or international model, use the correct ROM for it and your IMEI is not lost. From what you've posted, your phone should be an A2017G which is printed on the back of the phone.
ZTE A2017GV1.2.0B10 is the latest official Nougat for the G (international).
Hi, I get a notification to update magisk. then I update it and use the recommended action to update it. After that it asks me to reboot the device. After rebooting the device it goes to fastboot only. And I see the device now changes to US996 while what I have is H990DS.
Can someone explain to me what's wrong and how to fix it without losing all my data?
thanks...
Hi there,
all I can say is that is happened exactly the same to me just some minutes ago, I installed latest magisk update like I've been doing with no problems, just that today, after reset, its always booting stuck into fastboot mode.
I have a H910 and I also see the message about US996, maybe this is related to the method used to root the phone, If I recall correctly it had something to do with installing a US996 modified bootloader.
I still haven't found a way to get my phone back to life. All I can say is that I do manage to boot into recovery (TWRP, via the appropriate key combination at power on), so I guess I'll manage to flash something to fix this and return it back to life I hope

Thanks, but who said I ever applied an OTA? It was magisk that wanted to update itself, I've been performing magisk updates regularly for quite some time and never had a problem, in fact I can't even perform an OTA phone update as I have AT&T variant but with a different sim...
Other times, when updating magisk, I lost root but never lost the ability to boot...
I was running alpha-omega oreo with mk2000 kernel and updating rom, kernel and magisk regularly through TWRP (or direct install in case of magisk though magisk app) and never had this problem before... at least I can manage to boot from recovery/TWRP so hopefully I will soon manage to get things working again... that is, if I can copy some images to my SD card that windows insists that is corrupted but that's another story...
I ended up flashing whole rom again and everything is back to normal
I have an A2017U but since changing from stock rom B35 to B01, I have lost all sim card and phone functions. I've tried all these - B05, B15, B10, B35, B20,, B19, but all firmwares are identified as "not for this machine" error, and all relevant apps and "About Phone" information now indentifies the model as A2017G, which it certainly isn't. Is there a rollback set of firmwares I could use to regain mobile network functions back to this phone. Firmware installed is B01, and when I bought the phone it had B35 installed. I don't have a PC just mac, so all those nifty workarounds, I can't do.
Please Help

Hello,
Assuming you have stock recovery, you can get ZTE_A2017UV1.1.0B35 firmware here:
https://www.getdroidtips.com/zte-axon-7-stock-firmware-collections/
Normally the download file should be a zip, unzip it, you will find update.zip file. Put update.zip on the root
of your SD card. Then go to Phone Settings, search for update, it should tell you your current phone version
and the update it finds and suggests. Then tap on update : it will update for you then reboot automatically. First reboot
should be a little long (< 5 min). Then you should be back all right to B35 and phone OK since the right modem for A2017U is included
in the ZTE_A2017UV1.1.0B35 firmware.
Note : I guess you have applied incorrect A2017G firmware to your A2017U, this would explain the phone problem (incorrect modem).
Fixed!

I used B03 stock room and still had no phone functions, then I did another SD Card update with the B20 and it worked, I have all the phone functions back and am on the latest stock Oreo build too, I'm so glad to get it back, as I was using a spare Android phone on version 5, it was so slow, but it's fixed now.

The key part of the method was to remove the Google account before updating in recovery mode
