3g 4g issues - Sprint LG G2

I have an unlocked sprint g2. I moved to Oman a month ago. Now gsm services work fine but 4g and 3g doesnt work on my phone. Can anyone explain a possible solution to this? Do i need to flash a baseband? Will this issue be corrected if i root and flash a custom rom? Thanks in advance guys. Appreciate your help.

first make sure the 4g and 3g bands of your current provider are supported on this phone. If they are, then there is a rom which might help you get 4g or 3g but i dont remember the name of it (terrible i know) 3g could have to do with the apn settings as well...

Hey thabjs for the reply. I know about the 3g settings, even i thought about the apn settings. But then there are no options to change apn settings in this rom. Perhaps if i change the rom i will be able to change fiddle around with the apn settings?

(NQ)Can't Get LTE on AOKP rom on Rogers 1747M

Hey All,
So, for some reason, I am unable to get LTE when i am flashed on the AOKP jellybean rom for the SGH-1747M (rogers)
I did everything that was stated in Task's Gerrit (Changed the connection for WCDMA to LTE/GSM auto), all that does is work for a while on H+, then disconnects.
I've changed my apn settings to the Rogers LTE settings, which just cuts off communication all together
Ive flashed Rogers Modems, still to no avail.
The thing that bothers me is that other sgh-1747M users claim to have been getting LTE on the AOKP jellybean rom.
My question is WHY AM I HAVING TROUBLE!!!??? I know the Rom was made for an At&T sgh1747, so people may say thats why its not working, but people with Canadian SG3's have been able to get LTE on the same ROM im having trouble getting it on.
If theres anything at all im missing, can someone please clarify exactly what im missing and what I should do to get it working.
I love the AOKP jellybean ROM, i keep going back to it, but the LTE not working just hurts my feelings (since I am paying for an LTE smartphone plan). PLEASE SOMEONE HELP!!!
PS: the first time I ever changed from WCDMA to LTE/GSM autom i got a 4G symbol for about 30 secs.....never seen it again! HELP!
i dont have a gerrit. so im unsure what you are talking about.
you need to add a canadian LTE apn and then do this...
Enter *#*#4636#*#* into the dialer
phone information
set preferred network type
change to LTE/GSM auto

I'm not really sure. Being as I don't have a Canadian model its not something I can test. But I'm sure some Canadian users will be posting here to help you out soon.
when i try to change the preferred network it will not let me change it to anything else but to lte/gsm (prl) (i have the AT&T version)

Thats interesting. Maybe its because you are actually using at&t network. It works when I put it on LTE/GSM, but all I get is 3G and H+
Check your IMEI in about phone/status. If its showing 0, there's a thread for that.
If you're getting 4G icon and your mobile network status says LTE and are getting LTE speeds, then its cosmetic issue. I had that problem before.
What I did was I flashed Kyan's ROM 1.3 cause its based off of Rogers firmware. Once I verified I had LTE icon on Kyan ROM, then flashed the stock/rooted ROM after.

Interesting. I will try that method and see what happens. Thanks for the info; will post back with results soon
Ok, so after going through the whole process stated above, i WAS able to get a 4G symbol come every now and then. But before the connection actually finalizes and goes through (before it turns blue on the aokp rom), it disconnects and goes back to WCDMA preferred. I added the rogers LTE apn, and using that apn with the LTE/GSM auto selected allowed the 4G to come, but it keeps disconnecting. It even sometimes changes back to other apns on the list by itself
Anyone know if theres a way to lock the preferred network and apn settings?
enter apn settings, then REBOOT phone. After that, enter *#*#4636#*#* into phone dialer and go change to LTE/CMDA/GSM. that worked for me, I just needed to reboot my phone for the apn settings to work

I stumbled upon this thread and the above solution using the dialer code. Worked instantly, no reboot required. I'm running R4INS AOKP Jelly Bean port on a Rogers SGH-I727.

Mine works until I reboot. Then it changes back to WCDMA. I'm on Telus.
LTE on canadian i747M (Rogers)
I had similar issue with LTE after flashing to AOKP rom. The fix provided by AOKP (after every reboot, type in *#*#4636#*#* and flipping the network type from WCDMA to LTE_only, then flip to LTE/GSM auto(PRL) ) works. LTE will show up as 4G. I have the 2012-09-30 AOKP build installed.
Yesterday all of a sudden I could not get LTE anymore. Not sure what happened as the only thing I did was to activate a new account on Google. Anyway the 4G/ flipping did not work anymore. Reflashed the rom several times, still the same issue, my phone will not get LTE/4G.
This morning tried the following and voila it worked, thought I will share this:
Flip the network type to LTE Only, there is no connection, REBOOT the phone.
1. After reboot, flip the network type to LTE Only again, this time, the connection worked - what a surprise/thrill.
2. Flipped the network type to LTE/GSM auto (PRL), connection was ok and 4G came on and stayed on. Did several reboots and repeated 1 and 2 and LTE/4G was ok.
Hope this helps.
I don't recommend you to use task aokp rom! You won't get LTE real speed and Dev won't help you since you are not an at&t user! He couldn't care less about the rest so try liquid jelly bean which is a lot faster and better or milestone 4 and aristodemo! They have better support although they are tw rom but worthy anyways

Task compiles that ROM based on AOKP source, but AOKP officially doesn't support att. Although I didn't have problems getting lte on his ROM the fact that you have to set it every time you reboot is why I am using cm10 for now otherwise it's a good ROM!
I'm having the same issues on my rogers branded s3. No matter what I do I can get lte to even appear. My apn auto rolls back to the provided apn and if I delete that I have no data at all. Hopefully this does have an answer because the Rom is amazing

Alright I think I have it figured out. I added the rogers APN related all others and the only change I made was I removed the info under APN type where it said internet+MMS and left it blank. Saved the APN rebooted and I have lte now. I even rebooted my phone and each time it boots up its showing 4g without having to play with any settings

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] Is there any way to disable 4G on D851?

Hi guys, I'm living a non-4G country. I think D851 support 4G so it'll always look for 4G network. That'll drain battery much.
So, I dont know there's any way to disable it? I only use GSM/WCDMA. My phone is rooted without custom Recovery
Thanks

[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!

Maybe with hidden menu access via dialer,you can permanently enabled it...I don't know the actual code that might work for your device..but you can find it through here..In general threads maybe
I had to set the proper APNs on my H815, additionally I had to tell it to use GSM/WCDMA/LTE Auto under Network Mode in the Mobile Networks settings.
AT&T APN settings

After that, it's been using LTE where available.

Thank you @Daptonic . I was attempting to use the "ATT nxtgenphone" APN because it works better on ATT devices but I guess the ATT Phone APN is needed for non ATT devices. Rebooted phone and it went straight to 4g. Thanks for responding.
Edit: dammit, it went back to hspa again......
