[Q] No LTE on Boost GS3 - Sprint Samsung Galaxy S III

Okay well first off I have searched the forums and I haven't found a solution to my problem. I went and picked up my new Galaxy s3 from Boost and had everything working just fine. I recently flashed the LiquidSmooth v2.8 ROM and it's working fine except for the fact that I have no LTE. If I switch to CDMA mode, I do get 3G though. Does anyone know what the problem may be??

Have you tried calling Boost Mobile, and have them reset your Data.

I don't think it's that because whenever I switch to a TW rom, I have no problem getting LTE

ATT GS3 losing Data Network randomly

This is the Task650 and Ktoonsez AOKP. VERSION: d2att(4.1.2 JZ054K) from December 2nd release.
My data network goes in and out at random. It actually started happening about 4 days ago on an older build by Task650 & Ktoonsez but I saw the new one so wiped dalvik and Partition cache and rom'ed. Even after flashing the new ROM, data is acting the same way. It is completely random, happens when the phone is in use or when it is locked. I can tell when data connects for short spurts because I hear the notices for new emails. All in all today, I've maybe had 5 minutes of HSPA/3G data and the rest all I have is cellular network for calls. reception strong, and I am in areas where I always have good connection and speed.
Any ideas? Kind of frustrating if I am out to lunch and want to catch up on things (stuff is blocked at work). Also I am paying for data I can't use :/
fully wipe and reflash.. try a different modem

I am admittedly new to flashing, I just assumed everything was in the package. I flash the ROM and Gapps, is there a source for different modems?
This is definite disconnect of data DHTP. Can't get anywhere, and there is no symbol where there usually is on the reception bar. When it comes back for brief moments, it has either HSPA, 3g, etc.... on the bar.
are you able to send and receive calls? text?
I flashed that rom three days ago, and i had to replace it via warranty. it showed it had signal, but couldnt make any calls or text at all. then i Odin back to stock never worked again.
Don't think it has to do with any rom. Noticed that my wife's sgs3 has had a problem sending and receiving texts and the network drops a lot as well. She is completely stock with the jelly Bean update. My network has been a little suspect over the last few days also. Might just be the service.

Hey Guys, I may have found the culprit...sort of.
The wife has an iP5 and she said to me while we are driving to a holiday party 'I finally have official 4G LTE on my phone'. To which I of course ask what she means. Apparently the same day I started not being able to connect to data networks, is actually the day that ATT fired up their 4G LTE tower(s) in the Lehigh Valley area. When I do get data on occasion, it's when I bump down to 3G and HSPA. Unfortunately, the ROM has a bug where I cannot force it to look for just 3G, I go to save the setting and it immediately jumps back to LTE.
I may just have to flash to a version that definitely supports 4G LTE data. This issue occurred before I flashed to newest ROM, so it has something to do with the core build or modem that both versions use.
Ngriffin, if you find any successful modems please let me know. I like the ROM but I can't go without a data connection much longer.
So, for those who care, I flashed Gapps and also Flashed a new modem (http://forum.xda-developers.com/showthread.php?t=1831898) version UCLG1 and it's a no go. A few in my area said it worked great for them so now I am a bit discouraged. Northeast Pennsilvania Area.

Versions tried:
LG1 -------------Did not work
LEM
LH9
LK3 -------------Works but only 3G data.
LH1
CLI5
More info, tested using the Wife's Ip5 and realized we don;t have LTE at our house, so I'll have to wait until we get withing range of the LTE tower(s) to see if it has an issue. However, I now have data reliably.

That's normal. LTE is data only and isn't used for phone calls.
I've been running Task's AOKP on my SGS II and III for a while with no data issues. Check your APN settings. If you're in an LTE area, you should be able to sit on the ATT LTE APN and have no problems, even away from LTE coverage.

To update further, LK3 modem worked for a short while, but once I left the area of my immediate cell tower and it had to connect to another tower, it couldn't. I flashed ALL modems in my list a post above and NONE work. I'm kind of pissed right now.
Any ideas? I'll probably to a full backup and then flash a completely different ROM and cross my fingers. Is there an official JB stock ROM sans the bloatware that is stable and can connect to LTE (or any data network reliably for that matter)?
It was my APN *facepalm* Thanks for the suggestion. It was sitting on wap.cingular instead of the LTE and it was causing the issue. I'm on modem CLH1 and it is working, I have the 4G (3G) symbol now and data is connecting. Well, I learned something thanks! :victory:

I started having issues with mine about the same time. I haven't been able to figure it out yet. I had just gone to JB and flashed a new ROM. Then started noticing not just data being very spotty but also my calls (both incoming and outgoing) were very spotty too. Both seemed to only work about 50% of the time. I have since completely wiped and factory reset twice. I even Odin'ed back to a stock Rout66 jelly bean system but I still have issues
I have updated my APN to ATT PTA but that hasn't helped. What APN settings did you go with? Is ther some specific for LTE coverage? On the stock system now I can actually see the LTE icon when it actually chooses to connect.
Also, where did you find other modems. I was told in another forum not to flash any that weren't specific to Jelly Bean and all I have found is the stock I747UCDLK3 which is already on my phone. I did try flashing that seperately just to see if that would help but did not.
I need to get my phone working pronto as it is my main phone for both business and personal phone calls. Any help would be greatly appreciated. Thanks in advance.

I thought they changed the APN to "ATT PHONE"? Trying to find those details now.
EDIT:
AT&T Changing Default APN's... no more pta???

When you're on stock, only thing you can do is check with your carrier and they'll either tell you that it's something on their end being worked on or that your SIM card is faulty.
This happens to me on tasks AOKP ROM at least once per day, but it usually only happens when I turn on LTE. Basically what happens is the phone has cellular service but no data, after a few minutes it comes back. What I have noticed is that its to do with LTE so maybe there's a problem with that?

Task's AOKP doesn't set the default APN to LTE for Rogers so you might wanna make sure it's your default APN.

[Q] No LTE on some roms, and Other problems

Ok so I got my Galaxy s3 today and it seemed awesome and very responsive but I just previously had both Nexus devices so of course I'm rooting it, I had some problems rooting the first time but I seemed so fix them but now my problems seem like they are within the ROM itself.
For example on Synergy with Ziggy Kernel I get pretty laggy and I have no LTE? Can somebody tell me how to get LTE back?
Also why when I flash other roms like Hyperdrive I have issues with aroma failing at the end but booting up to a boot screen of Verizion LTE when I'm on AT&T.
But when I flash intergalactic ROM I get my 4G back, also my other question is will it show an LTE if its 4G LTE because on some roms it will have no 4G or show the 4G.
I was wondering if anybody had any solutions to these problems because I'm really trying to figure this device out, thanks.
1, 2, 3. For ROM related issues, its best to post in the ROM thread.
2. Intergalatic shows 4G and 4GLTE for 4G and LTE respectively. As for showing 4G or 4G LTE it would be on the ROM DEV. Check in the thread itself.
For missing 4G, check your APNs after installing a ROM. Some AOSP ROMs need APN to be added manually after flashing them.

No 3g or wifi

Good morning,
I've been reading the forums for a while for solutions and tips but I am stumped on this one.
So I had stock Epic 4g (SPH-D700) on the Sprint network that was rooted and running CM 10.1 just fine. My USB connection broke so I bought a new motherboard so that I could switch to Cleartalk wireless, which required a connection for them to flash. They flashed the phone and while in stock, 3g data worked fine as well as phone calls and texting. Even stock though, with new motherboard, wifi did not work. It wouldn't even turn on to search for a connection. After rooting and flashing CM 10.1 while on the new Cleartalk network, 3g data now does not work and it gives me this error "unable to resolve host get.cm no address associated with hostname." Wifi still behaves the same. Calls and texts still work but I currently don't have any way to connect to the internet via 3g or wifi. Please help! I don't want to go back to stock just for connection.
Thank you!

Sounds like 2 issues here.
1. You probably forgot to connect the wifi antenna when you swapped motherboards.
2. You don't have your APNs configured for Cricket after flashing CM10.1.

1. I will double check this as soon as I can.
2. Any idea how I can go about configuring the APNs? I saw a solution where I backup the APN's with an app while in stock then restore once CM 10.1 is flashed. Will this work for me?

Not yet but I will. Is Cricket the same process as Cleartalk? I've never heard of Cricket.

****, no it's not lol. Sorry, I misread. There isn't a ClearTalk thread in our dev forum that I'm aware of. You may want to search the entire XDA site and even Google for that carrier's APN info.

No problem. I will try some things and update this thread with the progress. Thanks again!
So it isn't the hardware connection for the wifi problem. I checked everything and it still didn't work. I even reinstalled the old motherboard to make sure I had all connections right and the wifi worked fine. I just discovered the Bluetooth also doesn't work.
I haven't tried repairing the APN yet, I will update after I try.
Using "APN Backup and Restore" did not work. The app runs and says it is successful but doesn't actually restore the APN's. Or it does and that isn't the problem.

[SOLVED] GALAXY S3 i747 stuck on edge!

Ok have had this problem for a while now feel like i should try to address it now.
my s3 is stuck on 2g (edge) the frequencies for 3g and 4g ( technically 3.5g or H+)are all supported by my carrier (jamaica - Digicel) i payed someone to fix it a while back and it worked and now it has stoped working again.
when i try to force 4g ( via *#*#4636#*#) i get it for a couple seconds and then signal drops.
also from the 4g stoped working i have noticed my calls dropping more frequently even when data is turned off.
any advice leading to a fix would be greatly appreciated
device
att i747 running 4.3 rooted and stock Samsung rom .
EDIT:
Solved this issue if any one encounters this problem with their device don't hesitate to pm me or reply to hear what i did

downloaded nv reader/writer
downloaded it from here
http://forum.xda-developers.com/showthread.php?t=2374063
then i made a backup of my imei just incase it didnt wrk...dont know how? watch this
http://www.youtube.com/watch?v=CQkUozRhGvw&feature=youtube_gdata_player
came across this in a forum and injected this nv item into my s3
http://forum.xda-developers.com/attachment.php?attachmentid=2297379&d=1380728466
and then turned on mobile data and put my phone in and out of air plane mode and 4g poped up
im guessing that imei backup only works for i747.
this worked for me. my imei wasnt missing but this fixed it.

4G Disappeared

I flashed the Lollipop version of Liquid Smooth on my AT&T G3 and at first everything was working fine, 4G included. After a couple of days 4G disappeared. When this happened it didn't just go to 3G, it lost all data service completely. I originally figured it was the ROM and flashed back to the previous ROM I had using the TWRP backup I made beforehand. Same story, no data service. Figured maybe it was the modem so I flashed a working G3 modem on here, same story. I flashed to a different Lollipop ROM, Resurrection, to see if that fixed anything, nope. This is the ROM I currently have installed. At this point I went and look at the mobile network options and immediately noticed 1 issue, the preferred service was 3G and not LTE. I had an option to change it to LTE but when I actually select LTE it doesn't actually switch, it just stays on 3G.
The one good thing I managed to do was switch the APN to one that worked with 3G. The APN that was originally set was "pta", I can provide the actual APN information if that'll be useful but I figure most ROMs are going to have similarly named APNs. 3G works on at least 2 of the APNs listed for this ROM, "broadband" and "wap.cingular".
I called AT&T and determined that I my 4G service wasn't cut off; not that I really thought it was anyway as that wouldn't explain why I can't even select 4G as a network type. I'm kind of at a loss as to how I just randomly lost 4G access without actually making any changes to the firmware or OS of the phone. I'm also at a loss of how I can get it back.
And I am just sitting here with 3G with speed of 2 Mbps...
No one has any ideas or advice?
