No cellular data after flash - ZTE Axon 7 Questions & Answers

I've successfully flashed LOS 15.1 using the idiots guide on page ~126 from marshmallow stock. I have the A2017 Chinese version (6GB 128GB).
Problem is that I can no longer use mobile data 2G/3G/4G. I get normal service to call and text, but no data signal (I live in the UK).
I've tried flashing the A2017G modem which gave me no service whatsoever, and the A2017 modem leaves me in the predicament I'm in now.
Any help would be greatly appreciated.

Did you try the network settings?
Settings > network > sim card > mobile network > network operators.
It should scan for networks, just choose your provider and let it register. If it doesn't work straight away, restart your phone.
Yours maybe slightly different to this, I'm running Beta Oreo.
I hope this helps

why did you try flashing the A2017G modem?
Check your IMEIs, i think i've seen some cases where a wrong modem wipes them

APN settings?

Thank you so much!!

[4g fix] on Fulmics Rom for verizon VS985

Four things to note before proceeding...
1. This only works for users having vs985 model outside the US or not on verizon network.
2. I'm beginner im not responsible for any harm to your phone , I'm just sharing what i did to attain 4g services.
3. May be you already know all the things in the post but it can be useful for beginners like me .
4. Sorry for the english as its not my native language.
So Hi guys i installed this rom and as usually i was not getting any 4G or lte network.
Then i go to my network provider's website to check on which Band or frequency 4g services are active. ( for this i just googled 'idea 4g band' and i am redirected to my network provider's website. Here 'idea' is the name of network provider.)
So i found that in my region 4g services are active on Band3
Different careers use different Bands to provide 4g services such as band40 , band17 etc
Then i go to phone's hidden menu by the Advanced Menu of Fulmics Tweaks.
In hidden menu i select Modem Protocol > LTE Band Selection
There i select Band3 but i got "Fail' message on screen , however when i select band4 it gave me a 'success' message.
It means on my phone band4 is active but not band3.
All this information of Bands are stored in Modem or Bootstack section of our phone.
May be fulmics rom is having a band concerned with international rom So now i need a modem on which Band3 can be activated by going to hidden menu.
So i just flashed 35b Bootstack compiled by @xdabbeb.
Which can be found in this thread http://forum.xda-developers.com/verizon-lg-g3/development/xdabbeb-s-vs980-2-0-0-t3231279
After flashing when i tried to select band3 in hidden menu it gave a 'success' message . It means Band3 is activated on my phone. And now when i searched for all networks in Networks Menu of Phone Setting. I got my network listed and i successfully registered on it. And got 4G NETWORK.
So first of all you should know on which band your network is working and then try flashing different bootstacks on which your 4g Band can be activated.
Flashing wrong Bootstack can brick your phone
""Do not flash any bootstack above 35b. Custom roms are still not compatible with bootstacks above 35b""
You can try 24b , 12b. (But im sure only about 35b as i tried only this)
Again I'm not responsible for any harm to your phone. Use your mind and search thoroughly before taking any step.

Hi there, thanks for the info. What area are you in and where did you find what band you needed? I have tried numerous times with all the bootstacks and never had consistent 4G.
@mopartonyg
I'm in India and i just checked my career's website to know which band they are using. However in USA Verizon wireless uses Band12 as Primary Band and Band2 , Band4 as Secondary band to strengthen the signal in densely populated urban area. So if you are verizon user in USA band 12,4,2 must be activated. I can't say anything about consistency as it varies from place to place.
Actually Verizon uses band 13 for it's primary along with bands 4 and 2. Not having any luck getting data to work on Fulmics with this method. I select band 13 and band 4 (as band 2 is not in my area) yet even with that I still can't get data at all on Verizon with Fulmics.
same boat here... actually the only band I can get working is 4. I have to assume the design of the international rom with the band they are designed around, just don't play nice with our CDMA harware/modem partition. I would suspect that the international roms would require some engineering for them to really work properly. not sure if just porting them over and chaning settings is going to get the job done. perhaps someone more intelligent than I could share some light, but there certainly is a conflict with how these roms communicates across the CDMA bands in the US

One thing i noticed here... that only Verizon sim users are facing problem regarding 4G whereas other international users like me ( and some of my friends in China are free to select any network ). So may be verizon is creating restrictions as when i was on Stock vs985 verizon Rom ( unrooted) , i was not getting any official ota updates. It always says your software is up to date. But then i found a statement in Verizon's website that you will not get any official updates if you are not having verizon sim.
So verizon knows what Rom and what sim we are using.

A couple of good approaches to the issue. Although it needs to be noted 4G is directly related to the band on each carrier (VZW, TMO, etc) See Below
Carrier 4G LTE Bands Frequencies
Verizon Wireless 2, 4, 13 1900, 1700 f, 700 c
T-Mobile 2, 4, 12 1900, 1700 def, 700 a
Sprint 25, 26, 41 1900 g, 850, 2500
Europe 3, 7, 20 1800, 2600, 800
If a specific ROM cannot be set to the correct bands above, it would make sense to me that Verizon wouldn't work in Europe on a stock VZW ROM. It would not be able to use the channels in Europe.
And vice versa, that Verizon wouldn't work in the states on an international ROM in the US. Whether the Verizon SIM is blocking that band, or the design of the ROM, would be a better question for the developers.

Warid's approved devices will definitely work with Warid's LTE network. For our "Warid LTE Approved' devices please visit the "Warid's LTE devices" section. You can also purchase LTE devices that support 1800 MHz (FDD-LTE Bands 3) from other sources. However, Warid doesn't take responsibility for these devices if they do not work on Warid's LTE network http://www.waridtel.com/lte/faqs
So it makes sense that if BAND 3 works international (see above) that you get 4G
The one thing I noticed after activating bands 13 and 4 (with the proper VS985 35B bootstack) in the hidden settings is when I searched for my network under network settings it does bring up Verizon but it fails authentication. So it's like there is something missing in Fulmics ROM itself that would get it to where the ROM will work with Verizon's network. So is it a matter of lifting whatever files from say 47A/47B into Fulmics that have the Verizon VS985 specific info to get it to work perhaps?

I think now its not a matter of bootstack. Because even when Required Band is activated we can't register to the Verizon. Xpirt mentioned in a post that he is working to resolve network issues in Verizon models. We can hope that this problem will be solved in next version However xdabbeb shared that the 47A modem won't work without the corresponding 47A secondary bootloader (sbl1). Unfortunately, the 47A sbl1 doesn't play nice with the last bump-exploitable Android bootloader (aboot) we have from 12b. If you use that pairing, you'll put your device into 9008 bulk mode(Hard brick).

The good news is we do have 47A ROMs that are using the 35B modem so there is potential that Xpirt could use that as a source for a fix with the authentication issue. So @xpirt if you need anyone to beta test fixes my VS985 is ready to help!

Looking forward to getting it fixed and use it as my daily driver. It would totally be worth a big donation, thanks to everyone working on making this available to so many.
Great discussion towards the development of the International ROM's for our VS985. I was able to get 4G with Andy's 30A ported ROM...although the signal bars never came up on my phone, I was able to get the 4G speeds. I noticed that the APN XML was filled with Chinese... So for whatever reason and way, my phone was able to grab "somebody's" 4G tower. I'm hoping the RIL (Radio Interface Layer) and libraries were pulled over and perhaps this could provide some more insight to @Xspirit

I am on BlackSoulxxx latest LG G3 Tekcafe v5.3 D85530A-Full G5 ROM. Here's what I did to get the bars with 4g data. I tested it out in areas where there is no cell service and in areas where there is 1x or 3g and the 4g came back. I even made a backup of the ROM wiped and installed another marshmallow aosp rom and others. I then went to restore BlackSoulxxx ROM and 4g signal still came back.
Steps I did.
1. Tot'd back to stock 10b and rooted and installed twrp.
2. Flashed LG_G3_Flash2BackupEFS.zip of the 10b rom.
3. Wiped stock 10b and flashed the 10b G3_EFS_Flashable_Restore.zip that was created from the the LG_G3_Flash2BackupEFS.zip.
4. Flashed BlackSoulxxx rom and after it booted up I had signals but not data until I entered the Verizon APN manually see picture of what to enter. If mobile network is greyed out flash 35b bootstack.
5. I entered the verizon APN and selected CDMA then global I got the 4g icon with signal bars I changed the icon with a buildprop edit.
I just don't get signals while in 1x or 3g but data does work still and it will get 4g again if your in a 4g area. The phone does say T-CDMA 64. Here's a https://drive.google.com/file/d/0B-EyVOQK1xDAa0VmbERXcUlrV1U/view?usp=sharing to change it to Verizon Wireless courtesy of @xpirt.

Great job posting your step by step instructions. I've been able to achieve all of the same on a host of international ROMS however with a couple of caveots. I can either have SMS/MMS working properly, or break SMS/MMS and have internet with signal bars. Question about the file above. This will just modify the header, or will it specifically put you on the Verizon network?

[A2017G] Unable to get 4G/LTE after b08 update

After the update to b08 I'm unable to recieve 4G/LTE. I tried to lock on the LTE network, but I'm getting 3G only. I'm making this thread to see which people have this problem, and in which country/on which carrier.

Germany Vodafone works with LTE B08 and B09.
Same issue with Vodafone in Netherlands (Utrecht), second SIM from T-Mobile is just fine. I changed slots to no avail. Will not roll back, will wait till next update.
Same issue here in UK on Three since B08. I've seen 4G appear very fleetingly in places where I previously had a solid 4G signal on my old OnePlus One.
Similar issue here (3,UK). Going into Network settings and changing to 3G/2G then back to 4G/3G/2G again seemed to fix it.

I have been in my work office for 20minutes and the phone shows E network. The only way I managed to get it to detect 4G was to manually search for mobile networks and select the EE 4G option that always shows up. Phone then connects to 4G with 3 signal bars and signal strength 108 32.
The phone often fails to pickup 4G even though there is a good connection.
Once phone has been manually connected to 4G it stays well connected so long as I stay in the same office location.
GiffGaff / Vodafone multisim. Using Vodafone for Data. 4G works no problem. I've upgraded using the file rather then OTA

Sorry for the n00b questions, but got this phone for a week now and what i don`t understand is the difference between several b04, b05, b06 versions.
Got Lineage working now and came from B11, and in B11 LTE works and i have a full backup from B11 but i can`t flash this with twrp?
What do i need or what can i do to get LTE?
edit: Just followed this guide. And flashed the "A2017G_N_Modem.zip" also and that`s the problem i think wich doesn`t support LTE, am i right?
GOOD NEWS:
I'm a tester for the Axon 7 now, and the developer team successfully managed to fix the problem in Nougat 7.1.1. I'm running a testbuild as we speak.

But after a reset am unable to get the Voice over LTE even after turning the VOLTE option switching on from the settings.
So, someone please help me.. i have tried different access point settings still no help..
Restart the mobile. Or try to change the Sim card. Even I faced the same problem in Jio but after changing the sim its working fine now.
Have you update the latest MIUI 8 firmware ?
Does the problem still exist ?

This rom is fake and you need to flash the original rom and then choose english rom and use it or then you can apply for unlocking bootloader and then flash xiaomi.eu rom.

-flashed twrp-3.0.3-n4-athene_shreps
-flashed – lineage-14.1-20170306-nightly-athene-signed with open-gapps full
-couldn't get LTE and learned that I needed to flash a N firmware (which is the same as a N radio from what I understand?)
-flashed TWRP 3.0.2-0-athene
-flashed athene_NPJ25.93-14_radio_M8952_70030.25.03.62R+FSG-8952-05.30
-still couldn't get LTE to work
flashed up to my current set up and still can't get LTE to work.
I'm at a loss on what to do next.
I no longer have my stock nandroid (missed place it-possibly deleted accidently) thus I do not have what my build number would have been on stock.
I dont have a preference if I go back to Nougat or stay on MM (get to use xposed) I just want LTE to work.
What should I do next? Any help would be appreciated and thanks in advance!

What are your settings of you are on Verizon? If not where could I find them? I have 2 options for APNs which I am assuming is for the dual sim g4+. Which one would I pick for the single sim? Will it choose the APN I want every time?

I am outside US mate, so i can't tell you that but maybe you can call Verizon and ask them if the issue is on there side? Did LTE work in stock 7.0 that you flashed? Are both your sims LTE? Pick the one which is In slot 1 as the slot 1 sim will support LTE. Have you checked your preferred sim for data connection? What is your preferred network settings?? Have you manually tried registering on your network in slot 1?

I compared my APN settings on my LG G2 and they are the same as in the G4+. Although I am unable to edit my settings in the G4+ like I am in the G2. Also, my G4+ only has one Sim slot but two APN options in settings.

I went to Verizon to activate a new sim card with no luck. Still no LTE. I've tried different radios, different ROMs with no success.
What should I do at this point?
How do I completely start over from the way I got it?
Any help is appreciated. Thanks

Have you tried the hidden menu code: *#*#4636#*#* Open the dialer and enter that code, you will get a hidden menu called "Phone info". About half way down there is a drop down menu, change that setting to LTE only. See if your LTE works then. If it does, change it to LTE/CDMA auto (PRL) (This is assuming you are on Verizon or Sprint or another CDMA MVNO)
If your phone has only one sim slot it should be talking about settings for 2 sim. In the flashable zip thread you will find MPJ24.139-64. Afaik that is a US build only. Also the radio is different it seems (athene_MPJ24.139-64_radio_M8952_70009.08.03.45R+FSG-8952-03.68.zip) Maybe you can try the non-Amazon version? You said you are not in the US but it's a US model, right?

Thanks guys I figured it out(but not really). I started over from the beginning and redownloaded everything and tried again and it took this time. Not sure what I did differently but I have LTE now.
However I am now having a problem with accessing Dialer/calls/settings when trying to set up Google voice. Dialer app crashes and sim reboots. Ugh...
I'm in US with US phone on Verizon and one sim card slot.
I am in the US, mine is the xt1644, is model. The OP is having problems with LTE. I was having problems with LTE - CDMA.
Are you sure the radio you're referring to is a US radio?

I am also having that problem with call settings. You just have to set up call forwarding no answer to go to your Google voice number. I know also the Lineage and or the latest jp25 radio thinks I have two sims.

Google voice is all set up as I've used it for years. I simply cannot get into the settings to change it over from provider to Google voice. Frustrating...
Not sure who your provider is, I think you said you're cdma. I think all cdma provider's use *71{plus your 10 digit google voice phone number} to forward voicemail to google voice.
Here is a link to Verizon's instructions.
I have never been able to set up google voicemail through call settings on any phone on verizon anyway, it just gives you a link to the instructions.
By setting it up with the above method, it will automatically forward all busy-missed calls to your Gvoice number. It will never go to voicemail in the first place.

Please help me, can't use other carrier sim on G930V

Hi guys, last night I trade in my S6 for S7.
That guy told me the phone is sim unlocked, I just need to manually adding APN and it will work. I am too stupid not to try with my sim.
I am in Malaysia, S7 variant should be G930F, but it's G930V, I tried two different carriers with manually input APN but the signal icon still blank with a cross:crying:
Besides, whenever I change network mode, it will revert to Global.
I can't select network operator too.
Is there any method to get it works with my local carrier? Flash rom from G930V to G930U or change IMEI will works?
flash "u" rom marshamallow..

Flash the "U" unlocked firmware on it. Looks like the phone is locked to Verizon. I would strongly recommend against changing the IMEI because that can add a lot of unnecessary complications.

Can I flash official nougat rom?
Any additional step or modification needed?
I see there are many firmware for different CSC such as XAA, TMK and etc. Which one is cleanest and works better for GSM network?
Currently on Verizon Offiicial Nougat 7.0 G930VVRU4BQC5
phones out of country with other networks, and att USA since note 2 came out.
I currently have s7 too and it travelled with me out of country as well no problems, I get 4g in most places, if not 3g until I can get to fast WiFi.
Ur carrier data bands must not be matching or phones damaged, in my expert opinion.
Once u put other carriers sim u either request carrier to send u apn via text msg where u just open it and it gives u option to save it.
Or the Sim itself will/should have those settings in it. And upon inserting sim then going to where apns are added, u may be able to select it.
A quick Google of bands of ur network can tell u, but I'm optimistic only a very few bands are missing off g930v/g935v
Edit: Yes Verizon phones work on gsm in global mode
There is another option in there LTE/GSM/UMTS
U will have to experiment between global or the one above mentioned, does the trick for me all the time
