LTE not in the list

Hi. I am using a E97510D stock rom, I just noticed that LTE is not in the list, just GSM and WCDMA. Anyone knows why? Thanks!

are you sure u use the correct rom then? if yes, u should see if u can get a modem for ur phone then...
modem can be downloaded here, but installing i dunno: http://downloads.codefi.re/houstonn/lgog/modem

Thanks for the info. I have the correct rom as far as I know, I also have a modem.img, but I don't know how I can flash it. Anyone care to help?

Interesting...I think I have this problem as well. I got my E975 here in the UK last week running 10E out of the box, and I have no LTE option, however my sim/network is only 3G capable at the moment. Do the options dynamically change with a 4G SIM or would I have to flash something?

I presume it's not SIM or Network related. As when I used a Custom ROM, like Avatar ROM, I get all list of available networks(LTE/GSM/WCDMA). But reverting to stock one gives me two options only.

On stock rom you will have to wait for operator update to enable acces to lte. My g came with 10c. After 2 weeks i received notification about an update(about 10mb)..after this update i had acces to lte. So,maybe you have to wait?

I just tested this: First I don't have the LTE option, then I tried flashing a modem for my phone. After that I lost my network connection, then I flashed the baseband again from my PC. And guess what? LTE appears, network connections' good, wifi is great! :laugh: :good:

try this..is simple: http://forum.xda-developers.com/showthread.php?p=42892508

This 'trick' also lets me select the LTE option, however I haven't tested with a 4G capable carrier yet. Looking forward to trying this out properly

[Q] G2 LS980 (sprint) Roms

Ive been looking around the roms on the sprint section to find another stock rom that is already GSM unlocked so it can be used on t-mobile, like the Cyanogen11 one but cant find a definitive answer while reading through the roms and change logs of the roms. i know this might be a stupid anwsers and sorry if it is, but im not used to dealing with sprint phones and the TC method never worked for me when i have tried to do it and i have done it. any suggestios. thank you in advance.

I think for now it's a test it and keep a list of what works or if you try some post your results here I'm sure we are not the only two wondering this. cm11 works good great data speed for me on att but would also like a stock option.

The TC method never worked for US carriers. Have you tried the build.prop edit method? Should not be dependent on the rom. For a stock rom I find OpTimuS DE excellent. I used it previously with the build.prop unlock and now with the permanent unlock (but I'm in Canada).

Use rom toolbox (or similar) to edit your build.prop... ***case sensitive!!!!***
ro.build.target_operator = SPR
reboot
ro.build.target_operator = OPEN
reboot, then
ro.build.target_operator = spr
reboot
The last one (spr) is done because you will get system UI crashes if you leave it as OPEN.

Blah, that didn't work, even with the sprint Sim. When I use the LG tool to go back to stock on picks up some service with the sprint Sim.

I don't follow. Why would you have a Sprint sim in the phone?? If you do this with a Sprint sim in the phone you will lose data. If you flash a rom or back to stock, you have to edit the build.prop again to activate gsm.

Haha sorry I didn't mean to make that confusing. But it didn't work with the T-Mobile Sim either. The only time I have been able to get any type of service bars instead of a red x over it is when I put the sprint Sim in and go back to bare stock

Actually now when I put my T-Mobile Sim back in, it shows all the service bars Grey but can't choose and operator or send a text.

You can use the app Tweakker to enter your APN settings.

the phone wants to resort back to cdma for phone service, grab an app called telinfo from the play store and use it to set your phone to GSM (auto PRL), then set your APN to get data working, best of luck!

[Q] 4G Lost After Flashing Firmware

Hi everybody,
I'm totally new in this flashing world and I was messing around with my new Xperia Z1 Compact trying to get Kit Kat installed because when I bought the phone it came with JB 4.3. I flashed Latest KitKat Nordic 14.3.A.0.757 unbranded, and everything worked like a charm until I discovered that I lost 4G connection (It only connects to 3G). I went to settings to select network, and LTE is checked.
I was reading about this matter and it seems that nordic ROM doesn't support LTE Band 7 (2600Mhz) which is the band in my carrier. I tried flashing Central Europe Rom and Global rom for journalists found here in the forums. None of them seems to support my LTE band. I want to know if there is any way to recover 4G changing any setting or if you know a link to any generic ROM compatible with LTE Band 7 (2600Mhz), or if there is any way to revert to my original Jellybean 4.3 ROM using PC Companion or Sony Update Service. Any help will be very apreciated.

Hello,
I am using the Generic UK .757 on a BAND4 LTE network in Canada.

you have checked off the first thing to do from the checklist..
second is to make sure your APN settings are correct.
All these are simple, but if still no luck, some labour is in order.
Need to do full wipe and clean re-install
IF you are not rooted, just launch Sony PC companion with the phone NOT CONNECTED and do a repair. It should by default take you to KK
At the time of flashing, You probably had the wrong boxes checked and unchecked in the WIPE and Exclude boxes..

I'll try the two options
Thanks guys for the responses.
First I'll try to flask UK ROM to see if finally I get kitkat working on my phone. If this doesn't work I'll take the second option with PC Companion to restore the original ROM. I'll post the results.

It seems this rom doesn't work for me

Hi Phil,
I found UK rom in this forum ver. .681 and flashed it, then I downloaded OTA update to .757. So far the problem remains. I discovered that I was wrong about My LTE Band, is 7 not 4. Apparently there's a carrier in UK with band [email protected] same as here (Colombia), so theorically this rom should work, but this is not the case. I'm trying to change more settings without luck. If you know something to help me, it would be very appreciated. Thanks.

Hi jewelkobayashi,
I tried the method you wrote, but, despite the phone being disconnected, it downloaded the same ROM that I recently have flashed (GLOBAL .757 commercial and Journalist). Is there any other way to download the original Phone ROM . I know my original ROM is GLOBAL-14.2.A.1.114 and the customization number is 1281-3723. I haven't found any site to download this exact firmware. If you know something, it would be very appreciated. Thanks in advance.

Are you sure about your customization number? Because it gets changed if you flash another firmware. Here's everything you need to know: http://forum.xda-developers.com/showthread.php?p=52011642 to download your firmware. By the way, what's your country, branding and SI-Number (so I can add your customization number to the list)?

Stop flashing random ROMs and check your settings! Unless you have a different model phone than the rest of us (there are three, D5503, M51w and SO-02F), then ANY Z1C (D5503) ROM will work, but they come with different APN lists as bundling every carrier in the worlds APN settings would be a waste of space. Go to Settings > Mobile Networks > Access Point Names, and edit or create the correct APN in there. Look at a friends phone or on your carriers website for the correct settings. This is your problem, no doubt about it.
Please note that some carriers (mine included) have a special APN for LTE. E.g. standard is internet.tele2.se, LTE is 4g.tele2.se on my carrier.
...I have no idea where you're getting your data from, because literally every LTE network in the Nordics uses band 7.

Finally it worked

Thanks for your response. I verified APN settings with friend's phones and it was identical. Finally I called my carrier's help desk and after some try/error setups with them, they gave me an alternate APN that worked until I came home where 4G icon dissapeared again. Then, I was surprised with helpdesk response when I called them again. "There is no 4G coverage in your home area". O.O What is intriging to me is that the phone displayed 4G all the time when I just bought it (Even with restarts and wherever i was) and this changed only when I flashed a generic rom. Is just a silly assumption, but, is possible that carriers can make things like force 4G icon in their custom roms to make advertising or something like that? Just asking. Anyway, Thanks a lot for the responses.

Help!!!

Ok, this is what I did to screw it all
Go to the ussd *#*#4643#*#*
Go to phone info
Go to setings and Select radio band
It gives me the option of GSM/UMTS band = USA Band
-> I no longer have WCDMA or GSM connection :S
(LTE still works...)
Now, how do I go back to my previous options? or does it has nothing to do with it, and the problem is something else?
EDIT> problem solved, I had to reflash my ftf by just updating the FOTA (not sure I needed this...) and the BASEBAND... Now I am back up and running again.. >D

Sprint G2 GSM UNLOCK (US Carriers) Easiest Method!!

*YOU MUST BE ROOTED AND USING AN AOSP ROM*
CM11/PA/PAC-MAN/LIQUID SMOOTH will do the trick.
*Pop in a US Sim card (Tmobile, AT&T, H20, Family Mobile etc.)
*Open dialer app
*Dial *#*#4636#*#*
*Choose Phone Information
*Scroll down until you see the Network Type
*Click the box and choose GSM ONLY.!
And that's it folks. You will see the service bars appear after about 2-3 seconds. Set your apns if not already set and enjoy GSM carriers on your Sprint G2.!

I didn't think it'd work at first, because of all the other unlocking methods out there, like changing carrier files, unlock codes, T-Mobile ROMs, but I can happily say it works I tried it with an old Metro pcs sim I had. I got the "No service" signal because it isn't activated, but at least its detecting the sim card Thanks for the info! Oh, & I was using the CloudyG3 ROM version 1.2 & it still worked

No LTE, since the needed bands are missing from the phone. But yes, 4G (HSPA+). Several weeks now on Cloudyfa G3 ROM v1.2. Pick "WCDMA preferred" in the mobile network settings, and choose the T-Mobile APN without LTE, although the LTE one seems to work OK as well. If you have any issues kick-starting the GSM radio you can download Radio Switcher from the Play Store.
The only issue is that some of the T-Mobile towers haven't yet been "refarmed" or "unlocked", so on this device in that case you would only get 2G data. For example at home I get HSPA+, but at work only Edge/2G. Hopefully that will change in the coming weeks to months as T-Mobile continues to upgrade its towers. The same issue applies to a Sprint iPhone 4S and Republic Wireless Moto X that I unlocked and am running on T-Mobile as well.

Guys I'm new to this rom update business, I mean I have done plenty of windows phones but none of the newer androids.
I have an LG G2 32GB Sprint (bad esn), purchased from ebay, but I'm in the UK.
Any idea of how to get it working with the UK?
Links and instructions would be most helpful
Thanks in advance

Sorry cannot provide links I m on the go. First you need to check if you are on latest ota which is zvd. If you're on zvc root with latest iroot. If on zvd search the forum there is an apk which you just install to your phone and run it (called towelroot). It roots even without reboot. Then search the forum for ls980 permanent unlock and follow the guide. Just use any root explorer to copy the files, restart and you are unlocked but with no speed data icons on status bar. The other way, is after rooting, install autorec (search for it - it's tricky, you might brick). Autorec is needed to install custom recovery. Then just pick a rom from cloudifa (g3 port is great with no bugs). His roms are made for gsm and you will be already unlocked. If you prefer aosp based, only one that worked for me after changing some settings and restarting is Omni. Couldn't make carbon (discontinued), vanir and mahdi to work. They didn't even recognize that a sim was inserted. Before flashing a custom rom, make a full backup via custom recovery and make sure you get familiar with how you enter recovery and download mode with hardware key combination. Keep in mind there is always a chance to brick and then you will have to enter download mode and flash back to stock with lg tool. If you are confused ask any questions and I ll try to help when I get home on my pc. Did all above a week ago and ended with cloudifa g3 port and is working great so far (I'm in Greece).

Also after installing a custom recovery, the autorec works great and I can understand the concept of it, but then when I flash with the cloudifa g3_1.2 it flashes but when the phone restarts it gets stuck (first time at 49%, then had to reflash using stock via LGFlashTool, then second time at the LG logo) so I have to go back to the stock rom, root it, unlock it and back to square one. Unsure what to do next?

In order to enable data you have to check your apn settings. If there are no settings, try to set it manually (Google your carrier's apn settings). When you are done and you get data to work try a reboot to see if they stick. I think in the permanent unlock thread you can edit this file with the apn settings and add your carrier's ones. Also delete those 2 files so you can automatically have data after each reboot.
Now I didn't really understand what went wrong while trying to flash g3 port. Have you flashed the appropriate baseband? It's very important in order to boot. It's mentioned and there is a link as well in the op of g3 thread.

Bought this phone on eBay few days ago and I started checking around about how to unlock it(though it'd be simple as any other phones, but I guess I was wrong). Found few threads talking about how to unlock it for US GSM carriers but barely find any information about using it in Canada.
Looking to root\use a custom rom and read that the CloudG3 rom will actually GSM unlock the phone,but will it work as well for Canada(will be used on Telus network)
Thanks.

As long as the band's are supported it should work.

There's a Rom on xda that converts the spring variant to the T-Mobile variant by flashing the Rom. It's basically a T-Mobile variant g2 cm11 Rom but with a Sprint boot.img and a few other Sprint files to make it boot. But if I'm not mistaken it has the T-Mobile radios in it. That should get you their full network experience.

Think this thread might be dead but if I get a reply it'd be great. Will the OP method work on the latest CM12 nightly? Or does AOSP here refer to only the CM11 variant?

Currently not the Device Maintainer for the G2. I'm working with the G Flex community now. I'm pretty sure there's a CM12 nightly already released. Updates will be posted in whatever thread you originally downloaded it from

The most annoying LG G3 problem with LTE signal - [SOLVED]

OK guys, i think that I found the solution that will be PERMANENT fix of the problem with the LTE network on our G3 [ I own D855 but i think that this will be equal to all other models ]
So.... i spent hours ... many hours to find this so i hope that you will appreciate my work and maybe buy me a coffee if this help to you too.
1. I had problem, when my phone connects to LTE network and WiFi at the same time my network coverage disappeared.
2. After few days my network coverage started to disappeare with no logic... every few minutes - i have network and in a minute i dont have network and that was a proccess that never stopped.
What i tried :
1. I tried 30b kdz
2. I tried 30b via TWRP
3. I tried all different modems that i found with all this rom variations
4. I tried to go back to stock lollipop kdz
5. I may be tried something more but i wont to think more for that annoying problem any more so... that is enought
So here is what i found:
1. Simply use a Prop Build editor [ i used ES File Explorer to edit Build.prop ] to go into the build.prop and change the "telephony.lteOnCdmaDevice” value from 0 to 1. There are two lines on in the G3 build prop. Make sure both have the value of 1. Then save. Then reboot.
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
First make a backup of your build.prop file !!!!
2. Deleting the file LTEconfig.apk works sometimes. The file is located in the folder: / System /app
Just copy it to other location and delete the file and restart your phone. I said sometime because with some combination of roms and kernels and radios it helped me, but not in every variation. You have to try yourself.
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
First make a backup of your LTEconfig.apk file !!!!
3. Next thing that i found is that editing the build.prop with this values have a massive effect too :
ro.telephony.default_network=11 or 13.
ro.ril.def.preferred.network=11 or 13.
ro.build.target_country=AU or COM or to your country code.
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
First make a backup of your build.prop file !!!!
4. Try to Disable Fast Dormancy. You can do this by simply open the hidden menu in your G3. This can be done by simply dial *#546368#*855# on 6.0 D855 or 3845#*855# on 5.0 D855 [you will have to find the codes for the other variations of G3]
so hidden menu > Modem Protocol > PDP Setting > Set LG Fast Dormancy > disable
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
So... i have no problems anymore with this network issues
If someone find something that can be done more permanent than this, i will be glad to hear and understand but for now this is OK i am sure because we can use our phones as phones.

http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/ try to download stock kdz or tot .... some older version like 10a for example. Flash it with flashtool 2014 or lgup but first in twrp advanced wipe and wipe everything... then when you start your phone "from beggining" try to OTA update to lollipop.... i hope that this will normalize your problem. I am not sure... you have to try it. You should restore backup from when you were stock ot efs partitions just in case before flashing new kdz...
Write if it helped because there are many people out there having strange problems with network connection.

Ok, its not lost time in fact... this means that you dont have hardware problem its software related and mostly in 30b version that you have installed.
In fact my last rom flash was with file downloaded from here http://devtester.ro/projects/lg-firmwares/ as thurasisyein said.
I dont know why.. for no reason... i just coughn`t find 30b 16gb kdz with fast speed of download here in the forum and i tried.

Thanks for this thread!
I had no 4g/lte connection after i flashed MM KDZ, and no matter what rom i installed it didn't work, after i tried these fixes i found an old backup to restore, after that straight to 4g.
Now installed another rom via twrp and 4g sticks. For me i think it was a regional issue. (on 855) Denmark.

OK, try to insert your sim card into another android device. Remove your sim card while your G3 is into airplane mode... insert it into another android device and wait to connect to 4g... when this happened put it back to your G3 and airplane mode off and see if this will make things better.

Hey guys, I have an AT&T branded LG G3, unlocked, under a mexican network provider (TELCEL), every band is supported by the phone and I'm using their SIM. I'm currently using Fulmics 4.2 Rom, but even on stock rom, since I received the unit, whenever the LTE signal was too low, or I made a call, the phone would drop the signal and switch to 2G. The problem is, once this happens, the phone remains on 2G and won't change automatically to LTE. I have to turn it off and on for it to recover the LTE signal. Will this fix the issue? Or do you think I have a faulty unit? Thanks!

4g icon missing
Please Help My LG d855 On Stock 6.0 4g icon missing but data is still working fine , but in another rom like AOSP , 4g icon is appear and fine , Just in Stock Rom my 4g icon is missing , But Data is fine , Just a icon , Anyone Help , Thanks

This is what I was looking for all month, thanks OP. I use a h2o sim for mt vs985 and every time I booted up my phone would complain about a non-verizon SIM. Also, I would only get 3G.
Changing the target carrier to ATT and default band to 4 in these settings resolved this after a reboot. The error is gone and I now have 4G. Thanks for telling me about this!

@mccloud90, thanks for this thread. My problem is slightly different (it it can be called "problem" at all).
Using an app called LTE Discovery, I can see that modem always chooses LTE Band 3, which is more power-hungry than other ones. For example, in my country, LTE (4G) Band 20 is much more power-efficient, but, for any reason, modem never chooses it. I can force the selection of Band 20 thru the hidden menu, but this comes with other annoyances, like the fact that I cannot do or receive telephone calls. In the other hand, using Band 20, I feel much less power consumption.
So the question is: are there any way or workaound to tell the modem/sytem TO PREFER one LTE Band?. Maybe some build.prop configuration or a .sh script?
Thanks and, yes, I know this is not an easy question =). I just wanted to know your opinion.

After installing Marshmallow using the KDZ firmware, LTE was not working with a Cricket SIM card accessing the AT&T Network. I then made a phone call and received an automated text from Cricket to provision my phone and this fixed the LTE data connection. The SIM card method posted by Varna above may also work to generate a provisioning request from the carrier which could resolve some connection issues.
