How can i tell what bands i currently have available? - G3 Q&A, Help & Troubleshooting

Does anyone know of a hiddenmenu option or an app or something to show what bands i have currently available?
I'm going to do some modifications to my modem and i need something to display my results.
I'm using D852 version 10b if that makes a difference.
Thanks

no LTE on at&t - unlocked m919

I've seen several discussions about this but didn't seem to find a working solution. I'm currently using GNF1 V3 NB4, I tried using the apn settings for at&t and also called them to make sure they have the correct imei number. Also, for some reason under the "Network mode" I don't have an LTE option, I only have WCDMA/GSM, GSM ONLY AND WCDMA ONLY. I am able to get 4G but no LTE. Is there any solution or any other way to solve this problem?

Change ro.product.name= in the build.prop to say jfltetmo
will it also change the speed or just add an "LTE" symbol?
Give you the LTE option in network modes and change the icon. Speeds? Probably since youll have LTE back

ok, i have the LTE option in "network modes" now, however the speed is more or less the same and I don't have LTE bar, not sure whether it's because of my current location or what.. is there anything else I could edit to try to make it work?
If I change the ro.product.model , name and device to at&t values would I get the LTE speeds just like an at&t s4?

When I bought this phone from T-Mobile I was still on an AT&T plan. Before I jumped ship over to Net10 Wireless I used AT&T's LTE all over Pensacola. That was on a sim-unlocked, unrooted, otherwise 100% stock M919. Did you double-check your APN's? Perhaps you're just not in an area where you can pick up LTE?
Yes I use the correct apns the ones that at&t gave me, but im gonna try to go back to stock then change the apns to at&t and maybe that will work.. but even if it will, I don't know if I could keep using GNF1 or would I have to use a different rom, anybody else have or had issues with getting LTE on at&t while using custom roms and knows roms that work? (Preferably tw)
See your network type in settings > about phone > status. Try to get LTE with your AT&T SIM on another phone then install it back to your M919.

[Q] D851 LTE europe doesn't work

hello every one.
My lte doesn't work. I already test with the rom paranoid and CM.
I m from morocco our 4g is new and i think is the same as the europe 4g (lte).
Do you have any idea ?
Pls help
Thank you for your time
up
Help pls i need to flash modem ?
Which carrier are you using in Europe? Are you roaming from T-Mobile or have you purchased a different service/SIM card in Europe?
Also, what country are you in specifically?
There was a guide somewhere on XDA regarding Qualcomm processors and band unlocking using QXDM (LTE) and QPST (GSM/WCDMA) though I forget the exact name. I believe there was also concern that it could damage antennas. Also I have no idea if it actually works and mucking around in the NV RAM space is very risky. I would not advise it.
Is at least the GSM service working? If so, is it really that bad that you need LTE? Personally I would leave it at "oh the gsm works, I'm good". :good:
Depends on the carrier you are using, is your phone unlocked? I would assume that it is since your can receive gsm signal.... Anyways, what you would want to do is check your network's APN and check our phones APN settings and add the 4g/LTE APN settings to your phone manually... Then restart your phone and try again, make sure you select the apn after adding it so you know it's active. Try that. If that doesnt work, then go into your APN settings again and just do (reset apn setings) or something along the lines of that which resets/restores your apn settings back to normal/default.... either one could work, try the first one first ofc!

[Q] Moving from AT&T to TMobile. How to get TMo specific features?

Is there any way to get Wifi Calling to work?
Also, hotspot seems to not work because of some AT&T specific check. Is there any way to bypass?
Not sure about the hotspot stuff, but the WiFi calling is something that has to be built into the ROM, as such, if you purchased an AT&T G4, you will not be able to use WiFi calling. You'd need to buy the T-Mobile specific G4 in order to do that.

I think it can be done.
Well, we have the system dump from the H811 (TMOUS) version, and the system dump from the H815 (international) version. I'm sure someone can look at both of those as well as the other devices that have managed to do this (S4, M8, etc.) to see the differences and make a flashable "wificalling.zip" file. I might dig into it later. No promises.

[LS980]4G/LTE not working

Hi, my lg g2 ls980 doesn't seem to work on 4g, even though the lte bands are supported by the device. I use a carrier which supports band 3, 5 and 40 and my device supports band 3 and 40. Sim card is also 4g enabled. Originally, the device didn't come with these bands. I added them using qxdm.
When i try to lock to lte using an app called Network Signal guru, it automatically changes to wcdma.
I've posted 2 threads about this issue before and got no response. Those who can help me, please do. It would help me a lot. Thanks!
ps: changing/updating modem doesn't help either.

I added lte bands using qxdm professional nv write tool. Check out the post on xda because it has very detailed steps. But the bands don't seem to work. I still dont get any network when changing to lte (bands show up in settings, though.) You might want to give it a try and maybe it could work. Btw now I'm using zenfone max pro m1 so I'll not try to rectify the problem anymore. Good luck

Yeah i know the post on xda but can u give the files n tools u used which application version? Only send the files u used to add the bands and i'll do the rest
The LS980's hardware (antennas, etc) only supports bands 25, 26, and 41. No software changes you make will add the hardware needed to support other bands.

activate preferred LTE band(s) permanently

I have G710EAW (LG G7+) which has by default active LTE Bands 1,3,5,7,8,28. However I live in Europe and I with my carrier I would benefit from band 20 as well.
What I am doing currently, is via service menu I am activating manually all the bands I need (including band 20) in modem settings. This works perfectly fine, actually I am so used to it I can do it within seconds. Naturally after phone restart all is reverted.
It is a minor inconvenience, hence the question: any idea how to make the setting persistent or any tool that would do it after each reboot?
I would like to avoid installing firmware from other model (if that's even possible, I am layman in this...)

I don't know if Tasker needs root but you may be able to accomplish it with Tasker.
Although it may be a pain to setup i think tasker has a subreddit that you may be able to ask somebody who uses it more than I do

Hi, I'm also looking to buy the EAW version for the dual sim feature. So you confirm the phone has all the LTE bands but some of them are locked by the software installed?
I need a phone dual sim that works in Europe and USA....

Well I do believe Qualcomm Snapdragon is an excellent platform and the build-in modem is capable of all bands. I do have EAW version (I think originally from Hong Kong).
The band selection is not available from OS, but if you dial *#546368#*710# there is a hidden menu where in
Field Test -> Modem Settings -> LTE Band Selection I have these bands available:
1,2,3,4,5,7,8,12,13,17,20,25,28,29,30,38,40
To my limited experience any combination works just fine (I am in central EU). The drawback is that after reboot (or airplane mode) only the default (1,3,5,7,8,28) are on.
Just for the hell of it. I tried on my US phone, can't even access the menu Sucks.

It works for me on the T-Mobile variant you have to use the stock lg dialer and type the code in you cant just copy it in
How do you know this has worked? I toggled on the bands that I need bu there was no 'success' or save prompt and if I exit and re-do the process all the boxes are un-ticked when I navigate to the LTE bands page.

Sorry for late reply.. I'm using stock dialer, and enter in manually, still doesn't work.. Maybe it is a T-mobile code or something.. I'm not use to having a phone were I can't access the hidden menues..

Weird it takes me right to the menu once I hit the # sign on the end
I get the menu ok just no indication it has worked and the setting has stuck.
