[A2017G] Unable to get 4G/LTE after b08 update - ZTE Axon 7 Questions & Answers

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.
Country: Netherlands (northem part)
Carrier: Vodafone NL
It worked on b05/b06.

In b08 thread there was also someone ( crashhouse) on Vodafone where 4g failed to work after upgrade to b08 ...
Coincidence... Vodafone... You'll never know.
Perhaps downgrade to b06 again if this problem persists.

I'm not really planning on downgrading, but I wish someone know's a fix.
I also read people having the same problem but on other carriers.

I'm assuming you'll already checked the settings for dual SIM ? Under network modus you can choose between 4g/3g/2g auto, 3g/2g...

I've excactly the same issue's. I did a rollback to B06. Just to make 4G work again. Hope they fixed it with the Nougat update.

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

They know about the problem and are working on a fix for it.

I flashed LineageOS coming from B08, still no LTE... It's driving me crazy, it's been weeks.
I'm now figuring out if I can downgrade to b06 and reflash LineageOS to see if that fixes it.

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.
A public release is coming soon. So stay tuned. @the_cyberspace

4G on D802 HKG version

I have a D802 Hong Kong version. In the secret menu (3845#*802#) i have found this: LGD802AT-00-V10C-HKG-XX-NOV-30-2013
Now, I would like to use the 4g connection in my country (Italy, carrier TIM) but the 4g option is not avaible in "network mode". After a test with another G2 (italian version and same carrier), I can say that the connection don't switch automatically on 4g but keeps the H+ one. So i think is necessary a modification.
Solutions?
Is it necessary to flash an europe radio? or something else? I'd like to keep the stock rom Lg but is not a fundamental.
Baseband: M8974A - AAAANAZM - 1.0.190036
Kernel: 3.4.0
Build: JDQ39B
I have the g2 for two days. I know it very little. I do not have much knowledge about it. Some good soul can explain to me how to do?
I need your help!
Did you verify that the device has the correct radio bands for the lte on that carrier?

I don't know how to check! On the box of g2: gsm 850/900/1800/1900; wcdma 850/900/1900/2100; LTE 2100(B1)/1800(B3)/2600(B7)/900(B8)/800(B20).
My carrier is Tim but i don't kwow which band uses.
In secret menu/LTE Band section: avaible band 1,2,3,4,5,7,8,17,20,40. No one is selected.
Can i flash V10E firmware for Italy on V10C firmware for honk kong (actually on my device)?
Flashing different firmware wont help. Its either your apn is wrong or you didnt enable lte correctly. I checked and TIM uses 1800 (band 3) lte which your phone should work with.

Hi,
I've a similar question and I hope someone could help me: I've a G2 phone using the D80210e-ESA-XX firmware.
In the product specifications, supported LTE frequency bands are 900/1800/2100/2600/850. I know that in Italy working frequency bands are 800/1800/2600. Now, my phone does not support 800 MHz: do you think is possible to upload a different firmware (IT or EUR ones) on my phone? With one of these firmware, does the device will work at 800 MHz?
Thank you so much.
I also had the D802 with Korean firmware!
Even though the phone itself supports LTE the Korean firmware doesn't!
I flashed the EU version and everything worked fine afterwards!!!

@popsi, @zacharias99 did you follow a specific procedure to upload the european firmware. I'm not so sure to perform it cause some month ago I've bricked an old Motorola (I don't remember the exact model) using simply a firmware of a different country. The result was a brick cause two firmware did not use the same way to allocate the memory...

My friend i don't really know where in this forum the instructions for flashing a new stock firmware are... (I am also new in this community)
And i flashed it with Greek instructions so my link won't help you and i don't want to post some link i haven't tested by myself...
Sorry i hope you can understand!
At moment i have no time, but if I would be you I would search in the G2 Section for instructions!
They must definitely be somewhere!
Did you subscribe for LTE with your carrier?

@zacharias99, I've checked that 4G can be enabled using the secret menu
1. Go to LTE-Only
2. Modem Settings
3. RAT Selection
4. Select GSM / WCDMA / LTE auto
as in the post http://forum.xda-developers.com/showthread.php?t=2494751
At the moment it doesn't seem to work for me, probably because my sim still has not been enabled for 4g.
Have you ever enabled this option (with the previous korean firmware, I mean)?
@zacharias99, @popsi: the new european firmware allows to navigate over the 800MHz frequency band for you?
Thank you

Hi,
the procedure using the secret menu definitively works on my D80210e-ESA-XX, but I need to re-select it after every reboot.
Does anybody know how to make it permanent or how to automate this selection on boot (maybe using Tasker or something similar)?

EXPERIMENT: Flashing the WW LTE firmware onto the US LTE variant

Recently with the delay on 5.0 for the US LTE variant, because of AT&T, I have lost my patience with them. I am looking for a way to rid myself of this BS while maintaining full stock software. I have heard that the variants of the tablet are actually not different, and the firmwares may work on either model. Has anyone tried this? I'm well aware the cell bands supported may change (but my carrier only requires one band, and the WW variant supports one of my carrier's bands). I would love to know if it works, and if I can dirty flash the package to keep my data, since the rom is basically identical.
I flashed OTA posted in general forum for LTE and using it in ATT. Unlocked bootloader, CWM, and root afterwards. I'm not quite sure what you're looking for?

Bricks.
No what i'm asking is if i could convert my device to the WW variant with a firmware flash, and thus avoid needing to manually flash OTA files becauze of delays. I know this isn't going to be the last update delayed on the US variant so i'm wondering if i can just switch the installed software from the US LTE version to the WW LTE version, without bricking.
Yeah.. I am thinking the same thing as well.
If it was possible without bricking the device, I would love to flash the "Rest of the World" firmware on the AT&T set too.

You're welcome to try it with the factory images. If it does brick, you can always restore through the same process. I plan on attempting it soon, but i am waiting on a microsd card.

Theoretically, the only thing that would be changed between builds is the GSM stack. However the OTA between the WW and the US version would not work by default. You'd need to go into the OTA zip and mess around with some of the build.prop info. Which then may cause MD5 mismatches when it is parsed, and would definitely affect subsequent OTA updates because of MD5 mismatches.
If there are Android 5.0 factory images available for the WW ROM you feel would be suitable for your geography, then this would be the safer way to proceed.
I remember when I owned a Samsung Galaxy S2, there was an XDA thread with flashable modems you could push to your device to get better reception in your area. Essentially the differences between the WW and US/CAN versions should only be the GSM stack, and perhaps some carrier-specific bundled app (like the AT&T app for example).
Just a quick update for those who are interested:
Well ... I just did it. Successfully flashed the RoW recovery image on the Shield Tablet LTE set which I purchased from US via Ebay. I'm still in the process of restoring but so far everything seems to be working fine.
Confirmed 2 things during the flashing of recovery image,
Quote:
1) Issues of Cellular/Sim Card on the US LTE set is almost certainly Lollipop firmware related. No problems on FW 4.4.2
2) Problem of Wi-Fi authentication error after sharing files via Super Beam ( Wi-Fi direct ) is also resolved after revert to 4.4.2
I think I will be sticking with 4.4.2 for now with the added bonus of file managers working on Kit Kat.

Thanks for the update. I am interested in this also.
So i'm assuming from your post you got LTE working? Which country are you in? Where do you get the factory images from?
I live in Australia and have the US LTE version. HSPA+ is good but it would be nice to have LTE working on my network (Telstra).

Actually, I don't have a 4G LTE micro sim card with me so I can't verify that at the moment. I am trying to test it out using my friend's sim card and will report back with the results. In my opinion, it's not a good idea to be trying my nano sim on this.
I'm from Singapore and the network I'm on supports LTE Band 3 & 7 and my AT&T Moto X which supports Band 7 works out of the box.
Got them from Nvidia developers website but you have to register for a free account first.

Yep I need LTE band 3 for my network which is not supported out of the box by my US LTE shield. If your network supports LTE Band 7 then your shield should also be able to access your LTE network as BOTH the US and RoW LTE shields support LTE Band 7.
So I don't think your experiment will help me. Is there any way finding out which LTE Bands your shield supports now that you have flashed the RoW recovery image?

I am not really an expert on such matters but let me try and if it's possible to find out the information you are looking for.
Why not try flashing it and give it a go ? There's the bonus perk of removing the AT&T app from the device.

Hi, I am currently using US LTE NVIDIA Shield Tablet in Singapore as well. I have successfully flashed the RoW recovery image to my tablet (since I'm downgrading from Lollipop as well, so I thought I might as well try), but I noticed that there is no baseband file in the recovery image package. I proceeded to flash anyway.
One thing I noticed after flashing is that I still am not getting LTE (half of Singapore is band 3, and my home is under its coverage). So, it's pretty safe to say that the baseband is not affected by the factory image.
However, it might also be that the latest recovery image doesn't cover the baseband, and it might be included in the previous updates. So, I'm trying to download the previous recovery images and see whether there are baseband images are there.
EDIT: baseband image is not in there. The baseband version is definitely still for North America (e1729-nala.4.05_0.6.3 @786934, notice the 'na' part?).

Sorry I don't really understand ... the RoW software cover for both Band 3 and 7 since the UK edition supports these LTE bands as specified in Nvidia FAQ.
You should still be able to get Band 7 coverage which the NA edition supports as well, right ?
Am I missing something ?

Thank you. That is exactly the information I was looking for. Unfortunately there is no point flashing the RoW recovery image if you wish to change your baseband (and then use different LTE bands like I want to).
Is there anywhere I can download the RoW baseband images? I remember they were readily available for my nexus 4.

As I said, the image doesn't include the baseband image. So, no matter what you flash on the rom side, it won't matter.
Also, about band coverage in Singapore, it's not a full overlap. Some areas are band 3 (south and west), while some band 7 (North and East). I know this from an M1 engineer friend. So, yeah, no LTE band 3 in this factory image here.
But not all hope is lost. If one day Nvidia decides to update baseband, it will then definitely include the baseband in the OTA or factory image. So, possibility of switching is still there.
Was there a baseband update with the latest software update (2.0)?
The factory images for 2.0 have still not been released.
In another strange twist when i turned on my tablet this morning I was surprised to see my US shield had LTE here in Australia. Which means only one thing - Telstra are expanding their LTE spectrum in my area!

I downloaded the OTA manually and checked the content. It doesn't have any baseband update. Also, just to confirm again, I actually re-installed Lollipop. The baseband is still unchanged (only the suffix @ part changed, but I think it's just some marker).
I checked wikipedia, and it seems that Telstra has band 3 and 28. There's a good chance that they switched your area's band to 3, or they simply add band 7 (the latter is, of course, ideal).
I read that Nvidia is preparing an update to the existing Lollipop system. Hopefully they will include a baseband update, then we can probably make the jump to the RoW ROM. For now, I'm sticking with the US ROM first.

Okay ... I see that you are not able to get Band 3 coverage. But just to confirm, you are still able to get band 7 4G LTE coverage on the ROW Rom right ?
My phone 4G LTE is on Singtel, getting pretty good coverage island wide on Band 7. Unfortunately, it's a nano sim and I'm hesitant to test it on the tablet in case in gets jammed inside the slot.
So long everything works fine, I'm sticking with ROW Rom as it will probably not have none of the nonsense whereby it require AT&T approval before release.
Sorry to trouble you on another matter, I have reported this 2 issues to Nvidia customer support but just want to check if it's just my set or an common problem.
1) Cellular data connectivity will not return after enable aeroplane mode. SIM card is subsequently not detected.
2) After sharing files using Wi-Fi direct ( SuperBeam app ), Wi-Fi connection doesn't auto reconnect due to failed authentication. Require manual intervention.
What I can say is this 2 issues no longer occur once I downgraded the software from Android 5.0 back to Kit Kat 4.4.2

According to Nvidia faq, the North American version that works on AT&T, T-Mobile and Rogers on LTE bands 2, 4, 5, 7, and 17 and HSPA bands 1, 2, 4, 5.
I see that this article ( http://www.cnet.com/au/news/telstra-expands-its-4g-services-including-the-700mhz-band-trials/ ) states that Telstra is conducting trials for 700mhz (Band 17) in your area. Maybe this is why you have begun receiving 4G LTE reception in your area ?

I initially thought it may have been the planned 700mHz expansion by Telstra in my area HOWEVER Telstra's 700mHz expansion is actually Band 28 (not Band 17) and my US shield does not work on Band 28 out of the box. Although LTE Band 17 and 28 both use the 700mHz spectrum they both use different parts of that spectrum so are not compatible.
What I think has happened is there is some LTE Band 7 coverage in the middle of town here which is where I was when I got LTE coverage today. As I understand it Telstra has some limited LTE Band 7 coverage with most of the LTE network being Band 3........ so I'll still have to wait until I can flash a RoW baseband which will hopefully give me Band 3.....

[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?

LTE not working on A2017G with Resurrection Remix - switched from Dutch carrier

Hi everyone,
After switching from the Dutch provider KPN to Vodafone I lost the ability to connect to LTE/4G networks. On KPN in both Stock and RR remix LTE was working perfectly without any problems.
What can be the problem? My first thought is that Vodafone is using different bands than KPN, witch are not supported by the Axon 7. But all the Vodafone bands should be supported.
Is there a frequency band or channel that is somehow blocked a custom rom? Also my device is listed as a A2017U instead of a A2017G, is this an issue? Looking on this forum it seems not really of an issue. I flashed the right Modem in TWRP before installing the ROM.
Is there anyone that knows how to fix this issue?
Hey Maxhuisman,
A few months ago i switched from stock 6.0.1 MM rom to RR Nougat and after that Darkrom and a few others. No matter which kind of bootloaders/bootstacks/modems i flashed, the 4G/LTE data service from Vodafone NL just did not work even even after making sure the right LTE bands were enabled in the free app Network Guru. After asking for advise in a few other treads i was told to go back to a stock or near stock rom.
I am currently on Sl1m's B08 Nougat rom where my 4G+ worked instantly after flashing. I am not going to try other roms for now until i'm 100% sure that vodafone LTE works on those roms.

Thanks for your reply, I guess I have to go back to stock or to Sl!m then. Very strange that it is not working with Vodafone.
