I have read that you can change your APN settings to turn off LTE. However, I found another way (with the help of carefreelife). Use at your own risk! I am not responsible for any harm you may do though it seems fairly safe to me!:
UPDATE: THERE IS NOW AN EASIER METHOD TO DO THIS WITHOUT PULLING THE SIM AND REBOOTING (check out post #47 below or use this link)
http://forum.xda-developers.com/showpost.php?p=37310325&postcount=47
[OLD METHOD]1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect.[/OLD METHOD]
I was attempting to follow this procedure for the S2:
{Trick} Get Around "RAT SELECTION RESTRICTED" on i897 modems! - xda-developers
...but I couldn't get the SIM out easily so I left it in...and followed the steps. It wouldn't recognize that the SIM had been reinserted so I gave up and rebooted...and it worked! No need to mess with airplane mode or anything just follow the steps above.
I was then able to follow the same procedure and turn back on the default setting which was "1) Automatic". After a reboot I am again connected to LTE.
Reason I'm using this: I'm testing a major battery drain issue that might be related to LTE/HSPA+ switching.
Reason you might want this: If you have poor LTE signal or even poor HSPA+ signal and want your phone to stop trying to connect to that network, this will stop it.
UPDATE:
A little bit of bad news here:
I have been on "WCDMA All" (HSPA+ aka 3G4/G, with LTE disabled) for 10 days now with ZERO problems whatsoever.
However, I am pretty sure that whichever you choose, if not "Automatic", you will be locked to ONLY that band:
i.e. if you choose "WCDMA All" you will not only be disabling LTE, but also 2G (EDGE) as well. You may not need it (and if so, it will not effect you) - but if your phone loses the HSPA+ signal, it will not fall back to 2G unless you change the setting.
I tested this theory by setting my phone to "LTE all" and trying to call myself from another phone. The call went straight to my voicemail. LTE is data only (for now) and when you receive a call, it switches to HSPA+. Unfortunately, since I had set my phone to "LTE All", it stayed on LTE and could not receive the call.
This may not be a deal-breaker but it's something to be aware of, for sure. I only tested "LTE All" because it was easy to do so, but I am assuming the same applies for the other settings...only "Automatic" would seem to pick the best available network.

Edited OP and changed thread title. Please help me test this. Thanks!
Just out of my curiosity, can you not do this:
settings > wireless and networks > more settings > mobile networks > network mode > GSM/HSPA
I have the Bell version, which is similar to ATT's, wondering if ATT disabled that option.

Yes, it is disabled on AT&T versions. If you try the method I listed above without removing the SIM card, it will be blocked as well.
AT&T does not want us to have any control over which network we connect to. It's been speculated that they want us forced on to LTE to take strain off the HSPA network. Honestly I think that's fine - though I prefer to have a choice - except that I suspect LTE switching is causing my battery drain issue and I need to turn it off in order to test that theory.

carefreelife at Android Central forums showed me that WCDMA All is the proper setting to disable LTE and stay on HSPA. It's working for me and seems to be perfect!

My battery life is great too - there just seems to be a bug that causes it to suddenly become terrible and drain fast until it's rebooted. This is just a method I'm using to test it.
It's possible that disabling LTE can increase battery life but I'm not sure there's any evidence that LTE uses more battery than HSPA+. On older phones the LTE was not integrated into the SoC and thus was a power hog...but it's integrated on the S3.
For users who are on fringe areas and receive poor LTE or HSPA+ coverage...the phone will use extra battery trying to connect and stay connected to those...even if it's [mostly] unsuccessful. Using this method would be a good idea for people who would rather just stay on the bands with strong signal and stop wasting battery trying to get on LTE or HSPA+ fruitlessly.
Thanks a lot for this I've been wanting to switch to 2g only THANKS

You can mix the different bands between wcdma and gsm and their frequencies,that way you can get the best signal in your area.
How's that LTE test coming?

I can't guarantee this works with any modifications to stock as I have only done it on my unrooted stock AT&T S3.
CM10. I just learned that you can only use dialer codes on stock roms. AOSP roms don't recognize them. There's a small few that work. obviously this one doesn't. Where can I find the APN info?
Nice find!! Works perfectly with my AT&T Galaxy S3. Going to test it out for a few days. I have 4G LTE where I live but when I go to college in the fall there won't be any LTE. This will come in handy!
However, with the WCDMA option enabled, does this mean you only have access to 3G and not 2G? Sometimes when I am in rural areas there is no 3G so I need to use EDGE or GSM. Hopefully with the WCDMA all enabled 2G is still accessible.

That's a great question. I have looked at it like a hierarchy but there's plenty of reason to believe it could be otherwise. There's not really anywhere in Miami I can go that doesn't have really strong HSPA+ so I don't know how I can test it. If anyone can do this test themselves and see what happens when you leave a 3G area please post results here.
Actually, once I am done testing the battery drain I could switch from Automatic to LTE and find somewhere in Miami where there's only 3G and see if it switches down to 3G or just loses signal entirely. Someone could also switch to LTE mode and try to receive a phone call...if it is truly locked on ONLY LTE then it won't be able to take a call...
The more I think about it the more it seems like this could be a major drawback of this method. I look forward to testing this later and hearing what you guys find as well. Thanks!

I'd also love to know if 2G works, but I can't while in North California. There isn't a single place within a 20 mile radius of where I live that doesn't have full LTE and HSPA+ coverage since so many people live here. I go to college in a fairly rural area in California though so in late September I'll be able to confirm if we can get 2G with the WCDMA method.
Hi everyone,
So, I've got an interesting issue, and I realize that it is likely my fault. I was flashing various ROM's (CM10, CM9 etc) on the phone, and eventually when I put the stock ROM back on, I was only able to connect on "EDGE". I called Rogers and they said my account checked out. So, I did more ttroubleshooting, and in that I noticed that my IMEI was set to "0". So, I found a guide on here to re-add the IMEI using QPST and I was able to get back on 3G, but no 4G/LTE. After rebooting and some time passed, I am now on 4G, but no LTE and this is my issue. Before you say 4G is LTE, I tend to want to disagree. I used to get LTE, and I did see it pop up once since I fixed the phone, but the phone crashed and i wasn't able to test it with LTE running. Since then, I haven't seen it again. I also ran the "Phone Info" app, and if I set it to LTE only, I never get a data connection, even after rebooting, pulling battery etc.
Why I think 4G is not LTE is because when I ran speedtests before I broke my phone, I was getting 28MB down, and 8-10MB up. now, I'm lucky if I'm getting 1MB down and .2MB up. I have once gotten 4MB down, and .8MB up, but this is WELL below LTE speeds that I've had in the past.
I'm hoping someone might be able to help me get back to a 100% clean, stock ROM, modem, firmware etc. I have installed 2 different stock ROM's that I found for the Rogers i747m; one is ~700MB, the other is 1.2GB. Both have the same issue with 4G only. I've also flashed the stock Rogers modem, and still no luck.
Any help would be appreciated, but here are some specific questions if you can help.
Does anyone have screenshots of their stock "about" page, and the "status" page in the phone menu?
Does anyone have a bone stock "complete" firmware/ROM for the Rogers i747?
Is there anything I can do to fix this on my current ROM (stock)?
Thank you!

So, here's something a bit more interesting. Just before bed last night, I caught my phone on the LTE network. I tried loading a few pages/apps, but nothing was working. AFter about a minute, I lost all data connection and it popped back up about 10 seconds later back on 4G and was working again. Not sure if this helps anything, but I did grab a screenshot when it was on LTE.
Anyone?

Thanks for that thread, but does anyone know why the person is removing the SIM and going through all that trouble when rebooting does the exact same thing?
I have used the #2263 menu to set my phone into LTE only mode, and I get no data connection, nor any cell connection either. Switch it back to Automatic and it jumps right back on 4G.
It is faster to remove the sim and enter *#2263# code lol. Once the sim is removed, a no sim notification should appear. Better than waiting for you phone to reboot.
I will post my lte apn setting for you. Hopefully that will help.

It could also be the modem... I have a link to a stock rogers modem. Just flash in recovery and you may have LTE again. http://forum.xda-developers.com/showthread.php?p=29517422&highlight=rogers#post29517422
Just fyi...
I also have a Rogers S3 and noticed that I am not getting the LTE icon on the notification bar after the first week. Now, I only get a 4G icon in GSM, HSDPA, LTE mode, and 3G/H+ in GSM, HSDPA mode.
However, with the 4G icon, I can still get speeds of 30Mbps down, 13 Mbps up, and under System Information, it shows LTE in Network Type.
My conclusion was that dont rely on the icon in the notification bar. Check the system information page to see the actual network type.
The only time I can get the LTE icon to actually show when I am connected to the LTE network instead of the 4G icon is through re-flashing the ROM. I have tried clearing the cache through recovery menu and it still wont work.
I know this doesnt solve your issue, but I hope this will help anyone that stumble across this problem.
Cheers
Thanks for posting all of that. My APN settings are the same, except the APN type. Mine is set to "Internet + MMS". If I change it, I am prompted with a menu to choose from and the settigns on yours are not in the list. Basically it has the folllwing list:
Internet + MMS + DUN

INternet

Also, flashing the Rogers Modem was probably one of the first things I did. I thought that would have been most likely.
My mobile Network type is UMTS:3 and I am definately not getting LTE speeds. I've heard people say that they only see the 4G icon, but get LTE speeds, but I'm only getting about 5down, and less than 1 up. I say that when I was on another ROM, it showed 4G, but seemed much quicker. Now I'm just hosed.
Out of curiosity, under the system settings, what do you have listed for ERI Version and IMEI SV?
Thanks!
Any other ideas?
Mine show ERI Version: Not Available
IMEI SV:01
Hope that help you.
Side note: I also note that for reasons of economy of battery when I switch to GSM network and I want to return to the lte network, it takes a long time to show me the lte icon....it's seem to stuck a few minutes on the edge even if gsm/hspa/lte(auto mode) is selected.

I'm pretty sure I did that...but you have to use your own QCN to generate the new "injected" QCN. As far as I know, it doesn't generate one out of nothing. Unfortunately, I didn't have a QCN generated prior to breaking it. Now the "original" QCN I have is "broken" so when I inject it, it's injecting into a broken QCN.
Something I was curious about doing was getting another Rogers S3 QCN (from a willing XDA member), modifying the IMEI and injecting that back into my phone. Not sure if that would break things, but it might be worth a shot. I'm pretty desperate at this point.
Anyone willing to send me their Rogers QCN, so I can replace the IMEI, and inject it into my phone? Worst case the phone blows up, best case I get LTE back, or just restore my current "broken" QCN.
Thanks!
So...I am now fairly convinced that it actually is a hardware issue and not a software issue. I noticed that it was on LTE again (4th time in a week). I was outside walking my dog. I checked tosee if it was working, and out of shock it was! I then downloaded and ran speedtest...got 28down, 9.5 up. BAM!
Now, here's the kicker. I am in a zone where I've always had 4 bars of LTE, except now I can only get it outside. I checked the signal and it was at 62dbm. Walk inside my house, and it jumps to 87+ dbm and drops LTE. I've always had full LTE signal in my house, work, everywhere, now nothing. Based on this, I am certain that the antenna/radio is pooched. Now I have to either get it repaired or get a refurb...ugh. Giving up my month and a half old phone for a refurb really blows...
I am with Telus, and having the exact same problem (minus the IMEI thing).
I flashed to CM10, and my LTE stopped working. Went back to stock, and it's still not working.
Setting phone to LTE only gets me no signal.
I've tested it in Toronto, Mississauga, Barrie (all LTE capable) and nothing is working.
Apparently, it's an issue with the phone. Search Google for Galaxy S3 radio issues (or swap radio for signal) and there is tones of threads. I have a refurb phone coming from Rogers this week, and I'm gonna leave it at stock. Really sucks...but LTE is the bomb.
I read on one thread that Samsung is supposed to push a code fix for the modem, but that's from a bunch of people speculating on the issue. How true it is...time will tell. I'll post back if/when I get LTE back on the new phone.
So, I just got the new phone and LTE is back working everywhere it used to with full signal and full speed.
I hAve this now too...but it's just the icon as I am getting LTE speeds.
Might call Rogers too...
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

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

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.

Hi,
I have an unlocked version of Fire Phone and have flashed the almost latest version of the Cyanogenmod ROM. I am using at&t wireless service but it seems that I just cannot use LTE. Based on other information I think the phone supports all the bands at&t is using. The network the phone is using is HSPA. I tried changing settings in the phone but it did not help. I searched carefully using related keywords but have not found anybody talking about this, and I wonder whether this is something too simple to ask or nobody else has ever encountered this problem. I want to know if there is something I can do to use LTE.
Thanks.

I have seen some issues about CM based ROM's and ATT LTE. Did you have a full LTE signal and good data speeds on the stock ROM before you flashed the CyanogenMod ROM?

Thank you for your reply. Unfortunately, I had already flashed CM before I switched to att so I do not have information about that. And currently I am not quite willing to flash the phone back to the native fireOS just for this because HSPA still gives good data speed...

Have you checked your APN settings and verified that it is setup correctly to use ATT LTE? Also, was this phone ever used on ATT before with the sim card you put in it? If not, then what will have to happen is this, I think: I found this excerpt which I believe is what will have to happen.
You WILL NOT get AT&T LTE on you phone unless your account is first provisioned with an AT&T LTE Phone. There is NO WAY around this. You must buy/borrow an AT&T phone that has LTE capability, put your SIM in that phone, and let the system provision your account for LTE automatically. This is NOT something that customer service, or a store clerk, can do for you. Once your account is provisioned for LTE (you will know because the LTE indicator will show up on the phone), you can then put the SIM card into your Fire Phone. At that point, the device will automatically select the "phone" APN, and you will get LTE (identified by the "4G" indicator).
Hope this helps
