Axon 7 (A2017) Network signal issues - ZTE Axon 7 Questions & Answers

Hello there, Ill try to explain my problem the best way possible
I own an A2017 China model, since I was stuck in B07 and not receiving OTAS so I transformed it to a A2017U, the problem is that when I transformed it I lost my network signal since it was the U modem, I flashed the China version modem but my signal only got back partially, I´m getting dissconnected too often and I can´t get 3G, I´m on ATTT and the zone where I live it´s 4g supported :/
I trid to go back to stock but I couldn´t flash the B07 firmware via MiFlash since it said that the format was bad (ERROR_BAD_FORMAT 0), I , I went back to B13 version via EDL flashing but I cant get 3g or a stable mobile network althought im on a China firmware, I could really use some help over here :c I even tried with the B15 firmware

[A2017] Lost signal network after flashing official A2017U B29 ZTE firmware

After flashing official A2017U B29 firmware from ZTE the signal network service is lost. I ignore this and continue to upgrade to Nougat successfully and I get lost signal. I notice that Dual Sim Setting is working.
Does official firmware overwrite original chinese baseband/bootstack? Is this the reason?
Can someone please upload chinese baseband/bootstack A2017 please?
Thanks so much

Yes, it flashes the US bootstack. You have to flash the one here, but the dual sim settings won't work.

Can I reflash my B2017G (US model) to European stock ROM? (ZTE Axon 7 Mini)

It just bought it in the US... I want it to behave like a stock ROM European Axon 7 Mini.
I found out that the US model has limited language settings available.
Thank you!

I have the same exact question, not much info on the web. Anyone know if this is possible?
Do you have any firmware to flash (not update file)? I have ZTE Axon 7 mini from UK market and I can't update to european 7.1 android system. If I use system update function it cannot see any update, and same situation is with stock RECOVERY - after clicking "install zip from SD" and selecting file, phone restarts immidietly with regular 6.0 system.

Yes, you can flash it with the European stock firmware if it is the same model no. My device is ZTE B2017G bought in the US. I accidentally selected US Band in the engineering menu and I lost network services because I don't use the device in the US. I searched all through the net, no luck until I decided to flash the European firmware and it worked perfectly. I updated the firmware to 7.1.1 from the Russian ZTE site and it is still working well.

How to install european/chinese ROM on US version of M3(BTV-W09)

Hi M3 users,
I would like to kindly ask you if it is possible to flash european(C100) or chinese(C233) version of the ROM to US version of M3(C128).
I successfully unlocked the bootloader, flashed TWRP(by greatslon) and rooted my BTV-W09. I managed to enable 5G via the build.prop modification too. But now I was thinking to flash over my US ROM(C128B003) with european one(C100B006) - is that possible and how difficult is it? I downloaded latest european build C100B006(1.8GB file) from Huawei's italian webpage and would like to flash it, unless there it may damage my M3. Is there any fool-proof way to do it safely?
Looking forward for your replies, many thanks and with best regards,
Tomas
Hi,
I have a BTV-DL09 (LTE version) EU C100 version.
I have successfully flashed C233, C199 and other versions. After this I reflashed the C100B009 and got my M3 like new.
Usually (with Huawei at least) the localized versions are interchangeable.
Best if you have also your original ROM, in any case

Many thanks for the info Nicolap,
so what is the procedure of flashing euro/chinese rom over my US version. Can it be done with TWRP? What is the safest way to do it?
Many thanks in advance

Want to flash C100 firmware
Hey all, Just got my M3 from China.
Model No: BTV-W09
Build Number: BTV-W09C233B030
Was wondering how should I proceed if I wish to flash to a UK version of the software? Any guides out there?
Many thanks for your help!
Not quite the same tablet but i had issues with updates on my EU flashed C100 (LTE version) rom as my hw vendor an oemregion partition was still asia.
To get things working properly i had to install the EU oeminfo partition THEN flash the correct firmware. Before that auto updates picked up nothing and on upgrading to Nougat things like bluetooth broke.
That was for the LTE version though.

How to revert to C128?

Hi
I bought an M3 Wifi US version BTV-W09C128, which was recently upgraded via OTA to Nougat B353.
I used the rollback files on a European Huawei site
https://consumer.huawei.com/it/support/tablets/mediapad-m3-8/
to downgrade to Marshmallow BTV-W09C100B006 to regain 5 GHz Wifi, and then found it was not possible to upgrade to Nougat.
I opened the calculator in landscape mode and enter () () 2,846,579 () () =
finding
Vendor Country Info (same as oeminfo?) shows
Vendor: hw
Country: usa
This seems like the reason why my M3 cannot do OTA updates now.
Does anyone know if there are files available on a Huawei or other site to enable me to revert the M3 to US C128?
Thanks in advance!
Hello Sam,
I did the same updates on same type of device. You can try firmware finder to download the update files. I was not able to use this, I am trying for 2 days to get back to Nougat, tried chinese, european and US versions from US. I also had some hard times getting back to android 6, after different firmware updates I got stuck on NRD90M test-keys firmware. Now I am back to android 6 using the rollback and firmware from huawey italian site but I'm not sure why it worked on 10+ try...
If you find a way please let all of us know the flow
Thank you,
Mircea
I did the same thing. I don't think there is a full stock rom for C128 out there that you can flash it back. I have done lots of search on the internet already. However, I like to have 5Ghz enabled and I don't like EMUI 5.

Change ROM from China to Global

Hello,
I just got a Redmi Note 7 Chinese variant but I live in India and the Chinese MIUI isn't that great. I want to change it to the global ROM. I have the fastboot ROM downloaded and even the recovery ROM. I'm hoping that someone has already addressed the issue but I'm posting this because I'm not able to find any. My phone is currently running MIUI China 10.2.13 and it has received the 10.3.4 update. I haven't updated it since it might increment the arb index. Can anyone give me a confirmed, safe and working method to change my software from China to Global? I understand the risks of bootloader unlocking and all.
