Hi All,
I just got the international Z5c, model E5823, which supports both tmo us LTE bands in my area (bands 1 and 12). When I have preferred network type set to 3G, I get more bars and have data connectivity. When I switch it to 4G, the bars go down to 1 or 2, and I get no data.
I did a logcat while switching from 3G to 4G and noticed that while switching, the icon switches between H+ and H, then eventually drops out. I'm still trying to see if there is anything useful in the logcat, but the one thing I noticed that seemed interesting was
Code:
D/StatusBar.NetworkController( 2598): updateIconSet, voice network type is: 13/LTE, data network type is: 13/LTE
To me, this looks like I might be seeing issues with some failed attempt to use voice over lte (as this phone supports it).
Regardless, does anyone know how I can disable voice over LTE? There was an option in the phone menu on the Z3 supposedly that would let you toggle, but I don't see it anywhere on this.
I'm going to be cross posting this in the sony forums as well, so if I hear back I'll post here.
Fixed it. I turned it onto 3g and selected "Internet settings" from the networking menu, which seems to have downloaded some configuration stuff from my carrier. After switching back to 4g I have fully working data.
My H961N does not allow me to independently set my network band for each sim card. Both my network providers operate on 2G/3G/4G however since I have gotten this V10 I have had inconsistent network usage. At first I would strongly get one network and the other would mostly be on Emergency Calls when indoors depending on where I was. I used the hidden menu code *#546368#*961#-> Field Test -> Modem Settings, from Modem Settins I have tried to set the RAT Selection and the Network Mode however when I check Engineering Mode both sims show the same band if I am on WCDMA Only or GSM Only but neither provider operators on the same band except for one on 3G. If RAT is set to selectively move between two or more frequencies then one sim shows Invalid Band in Engineering Mode. Using Network Mode I have tried to set each sim to different band but both would either show the same band or one would appear invalid under Engineering Mode.
Another Issue I have is I am unable to use data even though I have the correct APN for both of my Network Providers. I have verified that both sims do work when used in another phone, at one point I visited both Providers but none could give me an answer to my issue. One of my Providers did however try and activated a data plan while I was in their office and the V10 did show 3G and received data however upon returning back to my regular surroundings I no longer got any data. I have tried upgrading the V10 to Marshmallow and Nougat but the upgrade did not solve this problem, neither the one I stated before. But on Nougat both my sims did show 3G but strangely only when I have my Wifi active and using a VPN. Currently I am on Lollipop and rooted I considered trying to flashing a qcn, sec and nvm files since I saw a site listing them as fixing network and data issues on this particular phone, I have the files just in case. Any help would be greatly appreciated.
I have two used LG G8x - G850QM (unlocked) and G850UM (Sprint unlocked).
I am on T-Mobile for years.
The G850QM on T-Mobile shows wifi-calling on the menu and it works.
The G850UM has no wifi-calling switch on the menu, just not there.
I installed WiFi Calling app from Widget7 from Play Store. The app seemed to bring out a hidden WiFi calling menu. And the WiFi calling works. I confirmed the WiFi calls on my T-Mobile bill portal.
Hope this can help
Does it do anything for Volte?

I used two different VoLTE Check app. Both indicated VoLTE ACTIVE.
I dai!ed *#*#4636#*#* to go into Diag menu. "Phobe Info" indicated that
VoLTE provisioned
Video Calling Provisioned
WiFi Calling Provisioned
EAB/Presence Provisioned
But all the "switches" were grayed out.
This is in my daiily driver LG G8X g850UM on T-Mobile.
I assumed VoLTE is working automatically.
Most people with tmobile on this phone have found that for calls the phone goes from 4g to 3g when making a call. You will only see this transition if you are looking at the 4g indicator while on the call.
The concern is when T-Mobile discontinues 3g next month then you will not be able to make phone calls.
If you dont mind you might take a look as you make a call and see if it stays on 4g.
I understand. I, with 4 LG phones on Tmobile, am in the same boat with a lot of people. And I have purchased more LG phones- 3 V40 , 1 G7 and 3 Q7+ before I learned about the network transition.
Tmobile did a piss poor job in explaining the 3G shutdown.
Today is 4/1, with my Sprint-unlocked LG G8X, I can make a call and the LTE indicator stayed on.
This is what Tmobile has announced.
As of March 31, 2022, Sprint’s older 3G (CDMA) network will be retired
As of June 30, 2022, Sprint’s LTE network will be retired
As of July 1, 2022, T-Mobile’s older 3G UMTS network will be retired
Also Tmobile has delayed Sprint 3G shutdown until May 30.
Downloaded app and enabled, but all my buttons are still greyed out and it definitely still goes to 3g during a call? Not sure why it is not working on my phone?
It has something to do with the combination of native ROM, TMobile or Sprint SIM card in use, provisioning of VoLTE, and the (T-Mobile) LTE channels supported in your phone. I have not figured everything out yet.
It will be a rough ride for me until July 1 when the transition is over.
Forget what I've posted. I f'ked up. I mixed up 2 models.
I just received a T-Mobile email telling me my daily driver G850UM does not have the Volte turned on.
I looked up Phone Info and found Volte Provisioned switch is off and grayed out. When I wrote the post on March 31 the Volte Provisioned switch was on but grayed out.
I swap SIm card to the G850QM phone, and the Volte Provisioned switch is visible and in ON position. Look like I need to switch phone near term. And then find a way to cross flash QM firmware onto UM model. Need research. Fvk T-Mobile and the other two for doing their fake 5G rollout.
Thank you Buontinh. Got Volte, WiFi calling and video calling on my LG G7X G850UM on 20P software.
Uploaded the modded abl_a to both _a and _b. Insert an active T-Mobile SIM card, got new TMobile bootup logo. Got the wifi-calling switch. Got into Phone Info and saw votle Provisioned, WiFi calling provisioned, and video calling provisioned. Grayed out however. I made a call to my landline and the 4G LTE light stayed on. I guess it is working.
Still on Android 10 however.
The most difficult part was to get the phone on EDL mode. Must have tried 20 times before getting the "dark screen" EDL mode, only to learn that a Qualcomm hs-usb qdloader 9008 driver was needed too.
So I followed the below directions from reddit and it worked great on my velvet. I did the same thing on my LG g8x with *#546368#*850# code and I now have Volte, however phone still drops to 3g when it makes a call any thoughts on how to fix that?
There is a way to force enable VoLTE on the "LG Velvet 4G Dual Sim" specifically your version which is the "LM-G910EMW".
By default the feature is disabled on this model variant for who knows why.
Follow the steps below: 1. Click on the "Phone" app and dial "##4636##" -If done correctly it'll automatically bring you to the "testing" settings menu.
Click on "Phone Information" -you should see a list of VoLTE settings however by default they are disabled and greyed out but don't worry there's a way to reactivate VoLTE. (You Will Come Back to this Menu later)
Go to your file app and create a file named "enable_ue" -thats all you need to do just create the file, nothing more nothing less.
Go back to the "Phone" App and dial "#*462633*#910#" -This code is specific to the variant and will not work on other non LM-G910EMW Phones. Dialing this should bring up the "Hidden LG Menu"
Select Field Test>Universal Enabler>Create New Config -a menu with check boxes for VoLTE options appearing
Select the boxes as follows "VoLTE" "ViLTE" "VoWifi" "ViWifi" And finally hit "Confirm" -a prompt will appear stating "Vo Services Updated"
Immediately restart your phone to allow the settings to kick in
After your phone has restarted go into your Settings>Network & Internet>Mobile Networks -If done correctly the VoLTE option will now be unlocked and available.
Switch on the "VoLTE"
Now to double check that your phone now truly has VoLTE enabled, repeat steps 1-2. If done correctly the menu should now say "VoLTE Provisioned Video Calling Provisioned Wifi Calling Provisioned " -if these 3 are all switched on then you have successfully force enabled VoLTE on your LG Velvet 4G Dual Sim LM-G910EMW, congratulations!

Hello, I sintalled the app and it leads to a LG look menu I never encoutered with a WiFi calling switch !
However, when I go back to the app, then press again the button to open the menu, the switch is disabled.
Any idea how to keep it active ?
Hi all
i upgraded my LG V60 with 3 different android 11, the polish, the VDI italian and the V600EA20c_00_COM1_EU_OP_0219, and all 3 have no 5G.
Is there any solution?
Also, with the 2 first roms, the second screen is detected but does not show up.
Any hints?
More info. With this official rom V600EA20c_00_COM1_EU_OP_0219, the second screen is not detected at all. So it is getting worse ;-)
I found a solution that works
dial this to acces hidden menu:
*#546368#*600#
You have to choose "Field Test", then "Modem settings". You will have here many things you can change. Go to "RAT Selection", it will give you many more options than the ones you find under the regular "Network settings".
I tested here first "LTE(5G NSA) Auto" and it instantly made the 5G icon appear in the task bar! So I then hit the "GSM/WCDMA/LTE(5G NSA) Auto" option. I now have up to 5G automatic network selection!
Thank you for this information. I am on Cosmote network and I tried it but 5G logo didn't appear. For both "LTE(5G NSA) Auto" and "GSM/WCDMA/LTE(5G NSA) Auto" options on Adndorid 10 regions POC, SWC was popping up a window with "success" click ok but on all Android 11 regions SWC, NLD, VDI, TMO was returning a "failed" error. I tried 5G wardriving while commuting to work with Netmonster app, but didn't see any 5G antenna on the list. I'll need to try in city center where I know the 5G coverage is dense but I'm sure there is 5G in my area.
Keep in mind that TM firmware was showing me 5G on 4G network but Netmonster informed me that it is a false positive explaining what's going on. Can you verify you get 5G speeds on speedtest?
Most importantly what firmware did you use?
EDIT: still no 5G on any firmware I tried in my region.
I bought a cn version of gt 5g and im in philippines. We have 5g towers and sim but it still shows 4g. And the prefered network doesn't show up. Other phones are working fine. How do I fix this? Thank you.
Set Preferred Network Mode through Hidden Menu
Since the common hidden menu code does not work on our device ( *#*#4636#*#* ), there is another way we must use. 1. Download this app from the Play Store: Force LTE Only (4G/5G) 2. Launch app and choose "METHOD3: (Android 11)" 3. Under Set...
