Chinese model cellular not working - ZTE Axon 7 Questions & Answers

Hi All,
I've flashed @DrakenFX back-to-stock zip's for U variant on my Chinese one, both BootStack and StockSystem zips.
happy to confirm that everything works except the cellular network basically making this a tablet
Trying to go back to Chinese stock, the boot stack for that model has no mirrors on the download page (ZTE_A2017V1.0.0B10_BootStack_by_DrakenFX.zip)
would appreciate if anyone has the file and can re-upload it. Till then I'm stuck with absolutely no phone :crying:
Another option I'm willing to experiment with is to flash the modem so it will work nicely with the U-everything-else.
If anyone has reason to believe this will work and has the modem binary I'll go for it.
Having the U variant supported bands is a-OK by me.
I would've commented on the dev thread but as I'm a new user I'm still not allowed to

Here : ZTE_A2017V1.0.0B10_BootStack_by_DrakenFX.zip , just FYI next time you try to use a different variant Rom, you just need System.img & Boot.img (Stock System zip in this case using my files) , YOU DON'T need other variants Bootstack

Hi! I have the exact same problem - no carrier signal after I flashed B29 US ROM on my chinese Axon 7 although the rest of the phone works fine - could you please please please tell me if you got it working and how??
Best Wishes

Hi there.. I read somewhere that it's possible to flash the global ROM on the US model and unlock the 866mbps WiFi speed (2x2 mimo).. Is this actually possible? If so, is it possible to flash just the radio on Lineage OS and get the same effect?

@TgSn
Did ur problem solved if not, then may b i could help you

I have problem
[email protected] said:
Took me a while to find this on my old posts, but here it is. This should work with EVERY d802 kitkat aosp based ROM out there so here it goes:
All you have to do is look for the Meta-inf folder>Com>Google>Android and the updater-script file should be there. Download Notepad ++ and open the updater script with it.
The first lines that you have to edit should look like this:
Edit them so it looks exactly like this, and make sure to keep the same format. All you have to do is change the "d802" and "galbi" for "d803"
Like this:
After that, replace the boot.img with the Furnace Kernel boot.img (the one made for aosp, it works with most 4.4 roms), save and close the zip. Put it in your phone and flash, along with the G-apps and optionally the QuickRemote.zip if you want to get remote functionality.
If you don't feel comfortable with replacing the boot.IMG yourself, skip the boot.IMG replacing part and go straight ahead and flash the modified ROM.zip and afterwards flash the furnacekernel.zip
If I didn't make things understandable, just say it and I'll take the time to explain more when I get home. I'm replying from the phone and its kinda hard to do quotes and stuff on chrome

Depends on what Kernel and rom you used. Ever since they updated roms to use either LG 4.4.2 sources or just JB sources it got a bit tricky. It seems youre using a JB kernel on a KitKat sourced rom.
Hi guys, I'm new here from hard bricking Claro 803/801. I'm very confused on what to install and what not - the official version of TWRP seems to be 2.6.32 but there is a 2.8 material design version. Again with roms, I'm not sure what is allowed and what is not. For someone fairly used to Cyanogenmod on my One X and also having heard of Cloudy G3, what would you guys recommend
Question re: D803 vs D801
Hi, I was referred here from a reddit sub while looking for information, it looks like there are lots of knowledgeable people here so I thought I'd post.
First off, for context, I'm a complete n00b when it comes to doing any sort of modifications to a cell phone; pretty much everything I've read here over my head. Rooting? Flashing? No clue what those are
I currently have a D803, and I love this phone. But, I do NOT love my carrier, as I'm being charged ridiculous fees, so I'd like to switch. The problem is the carrier I'd like to go with does not support the D803, as they use the AWS 1700 band (from what I can gather), which means I need a D801, in theory.
I saw someone advertising they can modify my model of phone (among others) to work on the carrier I'm interested in, for $25. Do you guys know if this is even possible? If so, could someone explain to me what the risks would be?
Thanks!

While I cannot speak for the LG G2, I know that with the Skyrocket I was able to flash a modified rom to have it work with Wind's AWS system. It only worked in places close to their towers but never very well. However since the 801 (T-mobile) works on AWS you may want to buy one of those/swap or maybe see if you can flash that radio (D801). NOTE: I cannot guarantee that will work and flashing the wrong radio may seriously damage your device, or so I've heard.

use your imei first to figure out what firmware you need. nobody can help you without that.

this method gives me link for following version:
D80230a_00.kdz
but when i instal this rom my phone's touch breaks, giving multiple touch points at a time and dead zones, imei becomes 0 and baseband is aslo not present and phone memroy appears 10gb on computer.
this is the correct firmware for you. this is not a ROM but a full fledged update that you must flash using update tool. I suggest you ask on main forum about this problem...but one thing is clear. do NOT use claro update, or you may hard brick your phone.

Flashing a New Modem / Baseband

Hi there,
I just started testing a custom ROM (audax) on top of my G928G that was originally running with PDA G928GUBU2AOJ4 / CSC G928GZTO2AOJ4 with arter97´s kernel and Phillz Recovery.
All went well with the ROM flashing.
But then I downloaded the modem / baseband from the ROM´s thread (CP-MODEM G928F: Modem_XXU2AOKB) and tried flashing it with Odin (using the CP option).
I hit the start button and it appeared to be flashing... but returned a fail at the end.
The cellphone is fully operational.
What did I miss? Do I have to flash the modem AND the bootloader together for it work?
Thanks in advance!
Well... just tried flashing the bootloader and modem, and this is what I´ve got...
Any ideas?
You may need to get the equivalent for the G variant that you have. I've tried cross flashing modems before on my W8 variant, without success. It's possible that it may work with some modification, but I'm not sure what would be required (or if that is even right). If you just download the full ROM for the G variant from somewhere like sammobile then you can extract at least the modem and flash it..

From what i understand omega v20 does not support 900I. It also uses phoenix kernel which I have heard has compatibility issues with 900I. Try Omega V18 (lolipop) or if you want a marshmallow based rom, try something else. Remember that these posts were posted years ago and that last year's "latest TWRP" is not THE latest TWRP.
you may want to flash original firmware via sammoblie to get you out of this predicament first.
edit. also post on a more appropriate thread next time. or else no one is going to find ur question

Baseband Collection/ Switching Guide

I really think there should be a thread on XDA with tested methods to switch baseband as a lot of people face trouble with GPS etc on custom ROMs. Ideally we should be having a collection of TWRP flashable zips instead of having to install stock firmware via tools like Miflash and then doing everything from the beginning.
This zip from Davideavinavil is TWRP flashable and it works perfectly for me. It doesn't improve things drastically from stock Marshmallow Indian ZUI baseband but would be great for if your GPS is not working or something.
To get the baseband from latest Indian ZUI Nougat Beta follow these instructions from zukfans by Magz Heaven. Tested on my own phone which previously had the above Davideavinavil zip flashed and is now on M8996FAAAANAZM-1.76387.1.92759.1. I wiped everything TWRP then flashed this in fastboot and then went back into recovery and flashed ROM + GApps. If you want to run this in Linux open the bat file as text and use the same fastboot commands with those files in your pwd.
1. Will bootloader be locked again after flashing baseband?
2. Do I have to flash ROM after flashing baseband?
3. Does bluetooth connectivity depend on baseband?
Thx

1. Yes its possible that your bootloader gets locked after flashing. If you do it wrong and doesnt check it after first reboot you can brick your device.
2. No you dont.
3. Someone said when you only flash the NON-HELOS.bin file you can get problems with bluetooth. If its right I dont know.

Thanks for your response. Only reason i asked about bluetooth is because only ONE custom rom works for me bluetooth wise. I'm unable to connect to my cars headunit with any rom except resurrection rom. Would flashing a modem help this? my modem is 9-00026-M8996FAAAANAZM-1.63821.1

Flashing custom roms shouldnt change the baseband. Does connecting work on rr with this baseband? Do you have problems with other bluetooth devices except your car?

Sorry I probably didn't explain that the best. Flashing ROMs doesn't change my baseband but I'm wondering if changing my baseband will fix my Bluetooth problems. Yes RR works with my current baseband and my Bluetooth works with every device I've tried, on flashing to a different ROM none have worked sadly. I've tried to ask around if other people have issues but they all say their BT is working as it should haha

no signal after update in A2017GV1.2.0B02

Hello, I konw that the question has already been asked, still I did not find any solution so far. I updated my phone to A2017GV1.2.0B02. My phone is a Chinese model. Therefore I assume it's a bootstack problem. Still I did not find which bootstack or modem I had to flash... Thanks for your help

It always better to convert it to A2017U model as more support and clear guides are available. However, did you back up your modem and boot files and installed after changing the model if Stock Rock.
If LOs or RR, did u flash specific model und universal bootloader?
Thanks for your answer. I don't have any modem or boot files back up. Yes, I flashed universal bootloader but for the moment I have found the right files to flash and make my phone work again. What can I do ?
