Brand New Phone, No Working LTE - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

'm gonna try and make a long story short. Yesterday I purchased A S3 from ATT..Everything was working fine right out of the box no problems, lte and everything..Well earlier today I rooted my phone and everything seemed to be fine, I even flashed a rom and that seemed to be running fine also, but I noticed when I flashed the rom on the tool bar where it shows what data your running other than Wifi, it said H, don't know what that would be but I know it wasen't lte....So I thought maybe something was wrong with my phone, so I took it to the att store and showed them I wasen't getting 4glte..So they looked on the compyter and everything looked right, then they took it to the back where the service center was and flashed it back to factory....AND WHAT DO YOU KNOW??? It worked...I got 4glte right away..It said it right on the toolbar..I was so happy its working again like it should be...So I get home and root the phone again..everything went fine with the root, well it seemed like it BUT WHAT DO YOU KNOW...YOU GUESSED IT..NO 4gLTE...WHAT is going on here...and this was just off a fresh root no roms or anything...So I'm stuck I don't know what to do or if anyone else has expierienced this or knows a fix...I really want to keep my phone rooted so I can run roms and programs like Titanium Backup
So if anyone knows and can help I'd really appriciate it...thanks for your help and time...
I'm keeping my fingers crossed
As you can see from the picture you can see 4g on the status bar, but check out the speeds...and I'm in a great spot for lte..so something is wrong

Its kind of normal that lte dont work on some roms, you could just stay stock and it will all work, Im not sure why root would kill your lte, how are you rooting?

1st wrong thread, this has nothing to do with development, 2nd if ur getting 4g lte issues then speak to the company u got it from, because not alot of places can support lte atm its like a transition thats happenning 3rd what i can suggest you do is grab a tool like odin, and odin back to stock rom and then use snapdragon tool by mskip its the 2nd or 3rd from this forum up, and go from there and that should help u further on in getting back to normal , and if you're flashing jelly bean roms or what not, you have lte still but it'll show as 4g or what not, which rom have you flashed btw.

You need to check your APN settings and make sure you're using the proper LTE APNs for your carrier and make sure that LTE is available in your area 100%.
Also you need to enable LTE on the mobile connections screen within whatever ROM you flash.

but he's saying he's flashing a rom and losing LTE, but apn most the times stick, thats why i was wondering which rom was it, because then we can let them know to make sure their apn sticks make its easier for anyone else that flashes.

I know first hand wali and his partner in crime have stellar ROMs flash one of those guarantee you won't be disappointed

It could also be that he has lte but the icons says 4G for lte I think it's the case for some roms. Because the phone companies made us believe that hsdpa+ was 4G when in fact it's more like 3.7G more or less. What I'm trying to say is did you do a speed test to make sure?
4G might just be lte after all.

I know when on blackjelly it only shows 4 I believe but the speed test shows lte speeds.

lets blame the companies for skrewing everything up with toggles.
run a speed test and look at more info and see what it shows, also check your apn settings via settings/more settings and mobile network then access point names and then take a screenshot if possible by holding power + home button and post it up, because if u should have LTE service ur apns must be LTE otherwise you will be defaulted to regular apn which might throttle you like whoa well i know our ics doesn't do that but not that i hate anyone's ics, Nun, Ariel and Kyan all have done a good job in their ics's.

I don't know if this helps but go to settings and then about, then status and check network, most likely says UMTS or well it does for me on ALL 4.1.1 rom's. But, go to mobile networks and try to connect to another provider than yours, then when it says it cannot connect, re-connect to your own and I bet you will get HS+. Only problem is, if you toggle on wifi or reboot, you will have to do this all over again to retain the higher network connection.
I have not been able to come up with a solution yet and do not know if it is a 747m problem only or if it effects 747 as well.

Rogers Name Display Work Around

Hi all after testing for about a day i have found a way to get rogers name display to work on the tilt 2. Just had done a lot a searching and combined 2 cabs to get this working.
I have tested this only on the Energy rom and nothing else.
1st you need to install: rilphone for rogers CNAP.cab
then soft reset
2nd you need to install: NRGZ28 Tachi Dialer Disabler.cab
Yes i know you are all saying disabler for tachi but so far this is the only way it will work until someone can implement the settings for stock wm dialer to tachi.
Please Stick this
I tried it on my tilt2 with the cell pro rom it is making my phone run hot and draining the battery fast 10% in about 10 minutes. But it is also making my phone run alot smoother. Uninstalled with no luck still running hot and draining the battery fast. also "attention required" message flashes when I reboot. Time for a hard reset.

yes i agree i dont think that would be a problem with the rilphone.dll sounds like the phone is using either the data or phone itself all the time i would say try a hard reset and try this again. if it does the same thing again try a different rom. Im using energy rom i have always had good luck with his roms.
Thank you for those great cabs. Will be going back to canada in 2 weeks and will give it a try and report back.
I am using Mighty Mike's rom, do you think it will work?
regular phones with rogers/Fido don't need data. Using this cab, will I have to use data?

pretty sure it will work with any rom just try the rilphone.dll first and if it still don't work then install tachi dis-abler and should work. This will only work on GSM models not cdma/gsm so make sure yours is just gsm. And as for data the answer is no it doesn't use any data at all just like a regular rogers/Fido phone.
Thanks Hiwired.
Is there a way to make it work on CDMA
I linked this thread on ppcgeeks, maybe someone could collaborate with your work to see if they can make it work for us WCDMA users. I hope you don't mind.
http://forum.ppcgeeks.com/showthread.php?p=1851465#post1851465
nope i dont mind at all. and as it sits so far right now it will only work on gsm rogers. if you are looking for cdma then right now might look at program called truecallerid but you have to have 3g on in order for you to see it when the call comes in. it does use data as well to. im switchin carriers this week goin to bell so im going to try to mess with this on thier cdma/gsm 3g network

Thought WTH, let me try it on my phone CDMA. didn't work
I wish there's a work around for CDMA because I am using it on FIDO
ya as it sits right now bell only has caller number display BUT since they went with the 3g gsm network we might see something come out soon for it they have the proper network now just need the coding
A little off topic hiwiredjuice , but what radio are you using with this fix and the energy rom? I'm on the rogers network and I want to find an optimal radio to use. I am using Energy Rom, and i plan on using this fix aswell.

[Q] 1x problems

my evo when I flash custom roms will always give me 1x instead of 3g icon... not sure why is there a fix of any kind?
Your probably not clearing everything when you flash the rom. Make sure you wipe everything when flashing a new rom.

Try going into espt. (you need to be on a sense rom) Enter ##3282#. Go to edit mode (you'll need your MSL number). Select 'evdo', and make sure that the preferred mode is set to automatic. I don't remember if it automatically reboots your phone when you commit the changes, but if not, then reboot it manually after you change it. That may help ya out.

Good call, only reason I didn't think this was the reason because most roms don't have the icon change when you lose evdo.

Right, but now that a lot of the Sense roms are incorporating that mod (the mod that shows if your truly on 3g or 1xx), some people are realizing that they aren't getting 3g signal at all. Some may have been on 1x the entire time, but then when they switch to a rom that shows what you're actually connected to, they realtize they're on 1x. That trick works for some people, but not all. I think it'll help out though.
Same 1x problem no matter what i do
Ive had this problem for about 5 months now and it doesnt matter what ROM i switch to or use it the same and going in EPST doesnt fix the problem neither when doing what you just said to do with the epst but when i do change it from AUTOMATIC to HRC it goes back on 3G but the downfall to that is that phone calls and text dont come in to your phone until you make a phone call so can anyone help solve the issue why is this happening? I have a white evo hardwhere 0003 used all kind of roms even stock and same thing and know alot about phones and been messing with them since windows mobile 6.1 HTC TOUCH for sprint soo... And my girls evo is and stays on 3GrevA. her in not rooted and is stock tho while mines is stuck eternally 1xrtt.

you may have facked your radio at some point? I would tinker with different ones till you get the sweet spot.

This. There may not be anything really wrong at all. I mean, it sucks to drop to 1X, but the stock ROM was lying to you.
Now, if you ONLY see 1X all the time, yeah, that's a problem. But an occasional switch over to 1X (particularly if you're in a tough signal area, like the core of an office building) is normal.
I am on mikG Rom I have had 3g before I updated radios got the new stock rom but at home I use a airwave for signal wonder if that messes anything up?

Have you tried one of the new Sense 3 roms? The reason I ask...when you go into 'ABOUT PHONE' in settings these versions give you a network option that others do not. Check to see what it is telling you are receiving 1X or evdo. If it says 1X...you may have the same issue I had...borked 3G. Once I got it replaced..I loaded up the 3.0 again just to check what it now said..and you betcha...evdo was now showing and not 1Xrxx (or whatever it was).
I tried everything as well for about three weeks..you name it..ROMS/RADIOS/STOCK/CUSTOM/ESPT even took it back to fully stock and then rooted again (lost my .76Hboot in doing so, but phone didn't work right anyway... I was grabbing for straws. Luckily it was just under the first year and paid the 35 to have it replaced (no warranty plan). I travel and no matter where I went the speeds were terrible..ya..the 1X/3G/EVDO in the notifications bar is just for looks...but you KNOW when your stuck on 1X...frustrating.
This may not be the case....but
kinda of a simple fix... first of all stock sense roms always show 3g even if you dont have it... if on every rom you flash you keep getting the 1x AND you alreeady tried radios, nv etc upgrades and those dont work, then it is your PRL not PRI... 2 different things... to fix it check out a thread under deveopement ..Deck.... cause there is a fix there, or google prl and pri update evo on google.. you will need msl and be on sense and be able to use espt

No 3G data on my new SGS3

So I got a new SGS3 and it works fine, except when I am in 3G. When I am in 3G I can receive and place calls but no data. Att support was no help, so I figured I would check here. As far as I can tell it is either a APN, Gateway, or Account settings issue (the later being something I can not do anything about). I say this because my n1 gets signal fine here, and it seems to run fine, so long as it is 4g.
Any ideas? Also, does the SGS3 have EDGE support?

I have not rooted or anything, I have tried some APNs but I was hoping other people might help me out with something else to try. I don't really buy the whole " if you are stock... there is nothing that can be done" What if I was trying to get help with a stock developer build of my n1 (which I have previously) or are you asserting that without rooting I will not be able to fiddle with the modem settings?
What I'm saying is the phone comes ready out of the box. Unless you have changed something then it is a network problem. You will have to take it up with AT&T.
U can only do so much stock....and thats not alot! Root and use stock rom so u will have root access to see whats what...and to be able to control what u do or dont want ur data to do

Thank you guys for trying to help but I know all this. I am just in the period of time I can take it back and I don't want to risk that by bricking it while monkeying around.
I (Maybe) have isolated the problem, they said that I was set up for LTE and there are some issues with proper propagation of properties. Anyway problem "May" only effect people on ATT with Samsung S3s bought at BestBuy locations and the upgrade includes unlimited data. Still working will update tonight....
BUMP!

[Q] Rogers Galaxy S3 4G/LTE but I'm stuck on Edge?

Hey guys, I'm using the Galaxy S3 and my current carrier is Rogers. I've always been on 4G in the area that I'm in, and with the countless roms I've installed I've never come across any problems. Today I was trying out some new roms, but when I flashed them, I noticed that it swapped from 4G to E(aka Edge). Even if I flash back to my nandroid backup or even a fresh install if the previous rom I was using, I'm still stuck on Edge. Now even though it says I'm connected to Edge, never mind reduced speed, my internet just doesn't even work at all. For some reason even if I'm connected to wi-fi, no matter what I do it says there's no connection. I've read about flashing modems, which I have tried and it seems I'm doing it wrong? I put it on to my sd, boot in to recovery and flash it, but whenever I do I just go in to an endless boot loop. I've spent the past six hours pulling out my hair and trying to get this fixed but no solution yet, so now I've put my hope in to you guys! Any help would be appreciated!
Thanks!
P.S. I'm sorry if I can't reply back right away, I'm currently doing night shifts at work and even though it's 9:45am here, it's technically my bed time, so I will get back to you as soon as I can!
Some extra information if it may help - The rom I was using that worked properly was Triune 2, I've played around with a few roms since, but the one that originally swapped my 4g to Edge was Mark of the Dragon 3.0.
I can think of two possibilities:
1) Some ROMs will reset your phone's internal network settings to only use specific types of networks (e.g. when I first got my phone, the CM10 build I flashed at the time disabled LTE). You can check this by dialing *#*#4636#*#*, going into "Phone information", and scrolling down to "Set preferred network type"; you'll want one of the LTE settings.
2) Reportedly, your phone's IMEI will sometimes be erased during a ROM update (check this in the Settings -> About phone -> Status menu, or in the same "Phone information" menu as above). Check here if that happened.
Hey, I gave number 1 a shot and everything was fine, so I took a look at option 2 and my IMEI isn't gone, but it's showing "0". I searched online and it seems like "0" means it's been deleted, so I'm about to give it a go and see if I can get it up and running. Anyways, thanks for the reply! I'll post and update on how everything works out.
*UPDATE* Alright, problem fixed! I'm back at 4G, everything is running smooth and fast! Took a little bit but everything is working fine, and now I know how to fix this problem if it should arise again, thanks again for the help, I appreciate it!
Hey, I'm back again. Well, I thought the problem was fixed, I was back on 4G all day until a little after I started work at around 10:30pm when my network swapped back to Edge and it's been there since(now 6:57am). My IMEI is still intact as well. I've tried flashing back to stock with odin and injecting the file to see what happens but no luck. Unfortunately I haven't reached the 10 post marker which means I can't ask for help on that part of the forum yet, so here I am in your hands once again, any help from you guys would be greatly appreciated!

Out of curiosity, have you checked the "set preferred network type" setting again?
I've also heard recently that there may be some problems with Rogers APNs in non-standard ROMs, so it might be worth checking your APN settings.
Or, it could be an LTE network outage, unlikely as that seems...
Yes I have and everything is fine. However, I was looking around at a few things some other people have done, not with the exact problem I have, but similar, I tried something out and it worked. Dial *#197328640#>UMTS>DEBUG SCREEN>PHONE CONTROL>NETWORK CONTROL>BAND SELECTION>LTE BAND PREFERENCE>LTE ALL, let it sit there for about 30 seconds and then reset the phone. Do it again, go in to BAND SELECTION and then choose AUTOMATIC, wait 30 seconds and reboot your phone again. I'm back to 4g and actually, it seems faster than when I originally had 4G, but I think I'm just used to how slow Edge is now . Although the other fix got me back to 4G as well, but then it swapped back to Edge so I'll wait for at least 24 hours before I can confirm it completely fixed. Once again thanks for the response! Most helpful forums I've been on!
It hasn't been 24 hours but I thought I'd report back while I'm on my break. I'm still at 4G so things seems to be going well, hopefully it won't go back as it seems like it will stay at 4G. So, unless I'm having troubles again, rather than waiting the 24 hours and posting an update, think of it as a good thing that I don't report anything(or at least I will, since it's my phone ) Thanks again for the help, I appreciate it!

Thanks do much for this, I had the exact same problem after flashing MiuiAndroid and Wicked Sensations. Don't know which one effed it up but it was definitely one of those two. Also, I Don't think it is a placebo effect on the speed increase, cause mine is blazing fast after implementing this fix. You should maybe re-title the thread so others in this situation can find this fix, good find and thanks again!
Just want to confirm that this particular code can only be entered from a stock dialer? I I tried entering it from cm10's dialer and it doesn't do anything.

Although the other fix got me back to 4G as well, but then it swapped back to Edge so I'll wait for at least 24 hours before I can confirm it completely fixed. Once again thanks for the response! Most helpful forums I've been on!

There used to be a different method on the forums but all posts involving how to inject imei and then restore data were removed.

2 things that i can think of...
1)Make sure you have the LTE option selected in your Mobile Networks.
2)Take a look at your APN settings for you carrier. Flashing roms sometimes erases these settings.
That's where i would look first...
Cheers

Please let me know if you fix this. I'm having the same problem, and playing with LTE band selection doesn't work. When I force the band selection, the phone won't even go into service. The same thing happens with WCDMA.
Apparently, the nvbackup stores more than the IMEI. Even when you replace the IMEI, nobody seems to get data back. Unless, of course, you had a backup. Which, unfortunately, I was not smart enough to do....
Hey guys, I have the exact same issue as this:
-I flashed CM10.2 from a CM10.1 nightly which wiped my IMEI. I injected the IMEI using NV-items reader/writer.
-Reloaded stock ICS rom, IMEI returned but couldn't get up from EDGE
-Tried using the peoplesarmy's removed IMEI restore tool, didn't do anything
The phone still works, only its on EDGE all the time.
Literally the only solution for me was using my warranty and getting a new phone.
REPEAT: BACKUP YOUR **** OR YOU GOTTA GET A NEW PHONE!

4g not connecting anymore!

Titles says it all. I live in the baltimore MD area, and where i used to get 3-4 bars of 4g it wont connect to it anymore. I boot it up and it defaults to 3G. Ive tried playing with the mobile data settings and nothing has worked.
Does anyone have any ideas...because i use my phones data connection as home internet right now...
How long has it been happening? It possible the tower is being worked on.

It just started today. Im on CM10 and i would occasionally lose a 4g connection and would have to swtich the mode from lte/whatever/whatever to the other mode...and then back to reconnect..but thats not working anymore....
Edit: This is killing me because I use it for home internet. Im paranoid simply because this is the first month ive used 4G ever...meaning i never even turned lte mode on in the mobile data settings..i didnt even know it was in my area until the beginning of this month.. Im just wondering if me toggling it on and off to get it to connect through CM10 caused this... Thats why im coming here..to smarter people then myself begging and pleaing for assistance and guidance.
Could it perhaps be that sprint was just testing my area for 4g?? OR how long does tower maintenance usually take.. Or that they cut me off from using 4g after using 30gb so far? I mean i have an unlimited plan so it shouldnt be an issue
No they didnt cut you off, they would send a letter before doing that
Second, it usually takes about 2-3 weeks for maintenance to complete on a tower. If you're really concerned, call Sprint and ask if they're in the process of upgrading towers in your area. Who knows, they might even give you some sort of "we're sorry for the inconvenience" credit

Im eyeballing this thread like a hawk for opinions and posts like this. Thanks for your input.
When I first used 4G It was actually by accident on the CM10.1 Nightly. I pressed the Mobile data toggle square in the settings and i saw 4g, I was thrilled that it was in my area. Switched back to stable CM10 and checked if it was up and running. and much to my surprise it wasnt some weird graphical error just showing the 4g icon. It was legit working.
Still isnt working on any rom ive flashed here. Now though since the issue began.
What are the chances in the short time ive used it, that i could have possibly damaged my phones abaility to connect to 4G? Sorry if that question is dumb.
Very little. I doubt that its a hardware issue, because if it were, you would see other things like core apps FCing, the other radios taking longer to connect, maybe even hot reboots when trying to turn on 4G
Like I said, when you have time call Sprint. Most likely the towers are being worked on and they turned it off meanwhile
You might wanna also wanna get Sensorly (from the Play Store) just to doublecheck for LTE in your area

When 4G lte came on in my area it was on for a couple of weeks then they shut it down for 4 or 5 days then it came on and it's been on for almost 3 months. Just fyi this might be what's going on.

Wow thanks guys, you have put my mind at ease about all this. I was just so paranoid that I had specifically done something to the radio. So ill make a call to sprint to see whats up.
Thanks given to all !

No problem, let us know if the issue is on their side

I'm experiencing the similar issues, though I flashed over a ASOP Rom that has parts from cm10.1 though the Rom was ported from Verizon, but 4g worked perfectly fine, then when I flashed back to cm10 it stopped working. I'm debating on flashing back to that rom and see if it also does not have access to 4g at this time.
Edit/Update: I flashed back to my stock rom with root then flashed an updated MA6 Rom, updated the PRL, Profile and such, still no 4G. Decided that I'd mess with a few 4g settings, still problems. Then I flashed back to CM10 and my 4G works again.

Do that and post the results here, i will do the same. Sprint was less then helpful with this situation not giving me heads or tails over the phone.

I used http://forum.xda-developers.com/showthread.php?t=1910947

I don't think the LTE Mode menu needs to be utlized but I did see some interesting settings in there.

Thats a bit of work, so this could possibly be some janky setting on my phone still huh?
EDIT: I dont have my stock rom backed up. Dont know what happened to it. Could you explain what exactly I need to do to achieve the results you have posted man?
Sorry for the late reply. It could possibly be a setting on your phone. I say make a backup of your rom, flash a stock based rom, kernel & firmware, if it's not ma6 find an update or one based on it. Update the prl and profile. See if you can get 4g working on tw, if not then either restore back to cm10 or try messing with the lte settings, their are some that allow you to enable or disable and such. I also do recall a setting for ehpd 4g or lte 4G. After messing with them try restoring back to cm10. If you take a picture of the lte menu I can look and tell you what settings I clicked.
Edit: Just looked at the link try the lte force cause I know I pushed that button as well as a few others.

I'm looking through the forums and so far the only stock with root only is what I linked above but those are mianly updates. One Possibility if its not a problem I'd sugged Unrooting with odin and flashing a stock rom, reroot then flash the update linked above, then just make a Backup Called Stock with root MA6 or something. I'll keep looking though.

Unrooted, stocked it up. 4g didnt work. Re rooted..installed cm10 stable 4g worked. Seems like a consistent fix for this bug. Solved.

I just had this issue after flashing that Rootbox ROM which was ported from Verizon. I performed the above steps and everything's working fine.
