SM-G920W8 | No Option To Connect to LTE

I bought an Unlocked Canadian S6 recently, and it just won't let me connect to the LTE network.
Model Numer : SM-G920W8
Android Version : 5.0.2
Baseband : G920W8VLU1AOCG
Connecting to the LTE is not even an option. When I go in the Network Options, I get the choice between :
-WDCMA/GSM (auto connect)
- WDCMA only
- GSM only
I know for a fact that I am in the coverage zone, so no need to ask that silly question
I've tried different SIM cards, played in the options a bit, and factory reset the phone about 5 times now, yet nothing seems to work.
Also, when I try to do the update, it just reboots and gives me an Android logo and a failed Icon
I've only seen one other post like this from a carrier's support website, but no solutions were found.
**Update : For a reason, after a recovery, it will connect to the LTE for a bit or until next boot, then go back to what it is now.

First question, who did you buy the phone from? Second, Is it second hand? By default, Wind mobile does not allow the LTE option to be displayed in system settings as they as a carrier don't have LTE. It is blocked by the CSC setting for the carrier. As for other carriers It should leave you the option to connect in settings where you say it is not. If it is a Wind phone, You would need to change the CSC to enable the LTE selection. There is a method to force LTE even without option in settings, but I think it is removed in the latest firmware. Try dialing *#2263# in the dialer. It may bring you to menu that will allow you to select LTE. This is not a permanent method though as it will need to be done every boot. The other way, (If you are in fact a Wind/Mobilicity phone) is to enter dialer and enter *#272*IMEI# with IMEI being your devices unique code. If at all possible, take a full nand and Titanium Backup before doing this and be sure to transfer everything off the phone to a PC. This method wipes everything and I mean everything off the phone buy is a surefire way to enable LTE.

Yes, it was second hand. I didn't ask who was his carrier simply because it was unlocked.
I'll try it tomorrow, thanks for the information

Here is the menu you will see when you type the *#272*imei# code into your dialer. The codes are the carrier names. Mine which is GLW is Wind, BMC is Bell, RWC is Rogers, etc.

Maybe there is no LTE in your area...

It would still be visible in the Settings/Mobile Networks/Network Mode menu which it is not. His problem is more than that.

Sweet! It works :good: Thanks man
Now, would you have any ideas on why the update won't work? I didn't get much into it yet, but I will soon.

I'm not sure why it wouldn't update, but now that you have changed the CSC you can download the update and flash with Odin. Pick your carrier and go to town. The guy running the following thread runs his own firmware host. He's got amazing DL speeds. Usually takes me 6 or so minutes to do the 1.6gb file. http://forum.xda-developers.com/showthread.php?t=3086387

I'm having the same issue.

Connected with someone selling a G920W8 version. LTE is disabled and the codes aren't working. Can you reaffirm which unlock code worked for you? I'm on Fido, what LTE network are you using?

hi BCSC
Thanks for the details. I searched complete net and read all articles but nothing set me up with the proper thing. i read your solution i dialled *#2263# and all i got is service mode and in that i went to band selection , LTE and the all ....... Yes and its showing LTE in mobile data. THanks so much.
But now another issue, network is showing perfect but no outgoing and incoming calls.
in incoming its showing busy and on outgoing its not connecting to another phone.
And, Lte is not showing in mobile networks, There only 3 options still are showing.
Mine is same Wind S6 but i had to use in India.
Let Me know
Thanks once again
Cheeerzzzzz

Picking LTE from the service mode will note make it visible from the settings menu. Its more of a workarpund instead of a way of permanently enabling it. As for the issue of no out/in calls, my best guess is that it could be due to which LTE bands are being used or are available in India. Unfortunatly I have no way to test that option. I only was successful in getting the Wind LTE option on Canadian carriers.

LG G2 AT&T D800 Stopped working with 4G LTE

Hello,
My LG G2 D800 AT&T suddenly stopped working with 4G LTE, I am from Venezuela with a service plan with Movistar and I already had my sim card ready to work with 4G also had a data service for LTE, in fact I was working with 4G for aproximately 3 months under Band 4(1700/2100) but one day without installing any additional software the phone stopped working with 4G.
I placed the sim card into a different phone and the 4G worked on that phone.
I have tried factory restore without any third part application, also included the company APN and it is still in 3G not in 4G.
I entered into the hidden menu and selected the BAND4, my android version is 4.4.2 but it doesn´t allow to select 2G/3G/4G or select any prefered network you can just search for available networks and if I do I just find WCDMA and GSM not LTE. The other option available beside Search for available networks is Automatic Selection which usually selects the LTE network but now just select WCDMA.
I also tried entering *#*#4636#*#* and try to select any prefered band but that option is not even listed, I think is the stock rom.
I don´t know what to do now, I have tried everything but I don´t know if I have to install a custom rom in order to get the option to select the prefered network. I would like to keep my stock rom because I use quick remote and some other application I know I won´t find in a custom rom.
I hope somebody can help me because the LTE data service are really expensive and I am not using right now.
Please I need your help!!

Please help! No 3G or GSM, can't call, but LTE works fine.

I really need help with my device, I searched all over XDA and no-one seems to have the same issue as me.
Here is some information:
1) Nexus 6P (H1511)
2) 6.0.1 Absolute stock, no rom, no root, no custom recovery. Build number MMB29P.
Recently got a new Nexus 6P and imported to Russia. All of the major bands here are supported. And the phone worked excellent for a few weeks, but then it lost all 3G or GSM connectivity. Just randomly,didn't do anything with it, the only thing I did is move to another city but than I got back, the issue didn't resolve. LTE works perfectly but can't call or receive calls, can receive sms though. Reseting network settings and factory reset changed nothing. Tried manualy set network to WCDMA or GSM with *#*#4636#*#* command, the moment I switch to anything besides LTE the connection is lost. Contacted the provider, no problem on their side, my SIM works good in other phones, my phone with other SIMs - no.
I don't think it is a hardware issue because a few times I managed to get everything working after an hour of switching networks and bands with no particular order in the *#*#4636#*#* testing mode.
After a while I figured that if I set phone to "GSM only" on USA bands in testing mode, but at the same time set it to "LTE prefered" in the normal network settings menu. I am able to set phone to Band mode 7 and set the network back to 2G in network settings keeping it on " GSM only" the whole time and only after this compicated algorithm and after a reboot 2G and 3G starts working. But any reboot after that revertes everything back to only LTE stage. Also if I get everything working but than reset network settings everything stops working again.
I have no idea what caused such an issue, I really hope someone can help.

No 4G / LTE in Austria?

I'm customer of the local carrier "Drei" (Hutchison) but my Pixel (bought in Germany) does not connect to the 4G / LTE network.
The support of Drei is not able to help me. LTE is working fine with the same SIM on the OnePlus One.
Any clue how to fix that?

There is regional problem I came across. In India here we dont have VOLTE support on pixel

What LTE bands do they use on Drei?

Same happen to me in Portugal with MEO. I can't seem to solve it. Talked with my carrier support, they don't know why I don't have 4G/LTE.
I never got 4G, but my SIMCard has no issues with iPhone getting 4G right away.
Is it Pixel issue? I start to think it is..

3/Drei is listed here: https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe#Commercial_deployments
The specs of the Pixel are listed here: https://madeby.google.com/phone/specs/
That is all information I have got.
Is there any possibility to display information about nearby LTE senders via an app?

After activating "LTE only" via *#*#4636#*#* it works. Everytime I search for networks or reboot my phone it still connects via 3G and switches back to "LTE UMTS auto (PRL)".
Seems to be a software issue.

I use the phone on Verizon and don't have any problems connecting to LTE using any available mode (Global, LTE/CDMA or LTE/GSM/UMTS). However, if I set the mode to LTE-only via the menu, it will also reset when I either reboot the phone or if I just open the "Cellular networks" menu. I think it's how it supposed to work because that menu doesn't have the LTE-only option, so it resets the mode to whatever you see there. The solution is simple - if you reboot the phone change the mode again and don't go to the "Cellular networks" menu
Regarding why it doesn't work with "LTE UMTS auto (PRL)", it might be because Drei didn't configure a handover from UMTS to LTE on the cell site you're connected to. It looks like Pixel finds UMTS signal first, but doesn't know that LTE signal exists due to a missing handover. Another phone might be fine if it searches for LTE signal first. But if you can see another phone switching from UMTS to LTE in the same spot, my theory is wrong.

Lg g4 h810 works 2G only

Hi,
I bought this phone Lg G4 h810, it shows AT&T logo whenever i boot it and the problem is despite of network mode on lte/wcdma/gsm/auto it always runs on2G internet speed and shows E sign.
I am from india and many service providers are still not offering4G internet service. But this phone doesn't even runs on wcdma. My previous phone lenovo was nicely running on wcdma and always showed the sign H.
My cellular operator is idea cellular and i had a word with them, they sent me settings and all and help me input the settings manually too, but nothing worked.
I checked even the frequencies, idea cellular is offering UMTS B1(2100) and UMTS B8(900 gsm). I checked this on LG website and these bands are compatible with the phone i bought, but still i can't get anything more than2G. Why so?
Plus there is one more problem, when i switched it on for the first time it showed update available And when i tried to update, it showed error and now always there's an icon on top left corner of phone saying couldn't install system update. I tried restarting and updating the device many times, but it's still the same.
Any help is much appreciated.
Thanks in advance.

Have you put your Company APN?

Yes i did, the company executive even helped me to manually save the settings to run the internet in a 3G mode. But all efforts in vain.

Did you solve the issue?

Anything new? I have the same problem.

I have this problem too

Try hidden menu with *#546368#*810# and under Field Test menu / Modem settings if there is VoLTE on/off chose VoLTE and restart. I have done that and my phone starts working with 4G. Don't forget to set up good APN if it's not automatically set by network provider.

Hi
Under VoLTE there is another entry named "Session" and in there
RPR(on/off) switch
I enabled it and restarts but it is again on 2g
Anyone further on this issue??

I have this problem too
I was flash the stock firmware,custom firmware customizing the build.prop,changed the settings in the engineering menu *#546368#*810# disconnected volte,changed LTE bands forcibly. Nothing helps,dont work 3G LTE - 2G only(. I realized that I need to re-flash (change) the original QCN file for H810 and re-register IMEI , but I can not find QCN it freely available.

Hello there, i had the same issue. The fix that worked for me was searching for network manuallly and reconnecting again to my carriers LTE network. Worked as a charm. The issue maybe was a brutal handover as I had been travelli g from a city to another one 200 km away. So somehow I had been disconnected from the LTE network and left stranded in the 2g one. Try it it should work
