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!
Here are the threads I've reviewed and followed to try and resolve the issue.

Well I know you are right about one thing when it says 4g it's not the same as LTE mine says LTE when it's on LTE. I'm on Telus though. I have seen others in Canada with this issue after restoring the IMEI, maybe you should check that thread to see if there are any solutions.

I ran through every post in that thread, but still no LTE. Man this is driving me crazy. I'll pay someone if they can help me get LTE back... I've already restored the QCN info using the QCN creator posted in one of the threads.
What do you have for your APN settings?

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 + MMS
Internet + DUN
INternet
MMS
DUN
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.

check peoplearmy's thread - he added info on how to also restore data. if you have having a problem, maybe don't use your own qcn, generate one with his method and restore that. Worked like a charm for me.

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...
I wondering if someone can help me. My Bell S3 can longer connect to 3g HSDPA or LTE I've tried about 8 different ROMs. So bizzare. Does anyone have an idea about this?

Are your APN settings correct (Settings -> Other -> Mobile networks -> Access point names)?
Do you have the right network type set (in Mobile networks as above, or by dialing *#*#4636#*#* and looking in Phone info under Set preferred network type)?
Similar problem

I tried different modem without result on intermittent data but I least I had 3g. But all of a sudden I started getting no network at all. Not even voice. It seems my phone can no longer find any operator except for rogers. I tried aokp, goong back to cm10, no luck. Still no network..Ow i'm going back to stock and if it doesnt work well I dont know what elae to do. Hope someone here can help.
is your imei number still intact or has it changed?

Update: ive looked in *#*#4636#*#* facility and discovered that I cant change the band to use. When I select the menu itwm I get no options. Whereas on my girlfriend phone there are options. Maybe it can help pinpoint the problem.

+10 - Make sure you have an IMEI.
My problem is identical. If the imei is gone or changed what is the solution if any?

And fix it.
I've been searching both the T-Mobile and AT&T S III forums but haven't found my specific question.
I have an unlocked AT&T S III that I'd like to move over to T-Mobile. While I was in their store today I was told that I couldn't access their new LTE network in my area until Samsung sent out an OTA update. I know all LTE networks aren't created equally but I'm accessing AT&T's just fine, averaging about 32Mbps down and 10Mbps up.
I can't find any information about a Samsung update that would let me access T-Mobile's LTE network. I did a few speed tests with their SIM card in the store and the best result was 3Mbps down and 1Mbps up.
Any thoughts on this supposed OTA update or what I'd need to do to access their LTE using my unlocked AT&T S III?
For what it's worth, I'm currently running CM 10.1 M2.
Well according to this http://en.wikipedia.org/wiki/List_of_LTE_networks
Both At&t and Tmobile use 1700/2100 AWS. So once Tmobile releases the new Galaxy S3 someone can extract the radio from it's firmware. You could then flash the radio on your device. Alternatively you could simply enter the APN settings from Tmobile's Galaxy Note II which already (due to recent firmware update) supports Tmobile's lte network.
You can use this site to check on the progress of Tmobile's lte deployment.http://sensorly.com/map/4G/US/USA/T-Mobile/lte_310260

The APN change is a solution I haven't heard about. I'll probably head back to the store tomorrow to test this theory. I'll give feedback regardless of how it goes.
Please do I had the exact same question and I would appreciate it. Thank you.

I wasn't able to test this theory today because I couldn't find reliable T-Mobile LTE settings. I also read that changing or adding new APN settings can have adverse effects like Google Now not working. This makes me a little hesitant to try it even if I can find the right config.

Ah ok, you should be able to delete apn settings you add after testing. I don't have the phone in my possession or else I would test it myself. The settings I believe are changing the apn to fast.t-mobile.com while keeping everything else the same.

Hi all, ever since stock went to JB 4.1, I can not get phone to work on any Rom. Any ROM I flash, many and all radio flash and kernel flash. No matter what, I can not get phone to work on any Rom, except stock rooted Roms. I have T-Mobile SGH-T989 SG2! I wiped everything, tried touch and non touch CWM and just can't get phone to work. I tried every radio that is posted and read all radio issue threads. I even started from a fresh Odin stock flash with wiping everything on phone and sd card as well as external format. All roms that I flash work, but cant not connect to T-Mobile! I even manually applied APN's. Some Roms will detect T-Mobile and it won't connect. Keep getting AT&T, but won't register. This is the second thread I started, but with only one response for help that I tried. PLEASE, anyone with some advice, Thanks!

Try Network app from Market, and select GSM Auto (Prl).
Or go to settings, more, mobile networks and network mode and select GSM/WCDMA preferred.
Or go to EDGE / 2G only as a test.
In CM 10.1 and SlimBeam weeklies which I use, it seems to default to LTE/WCDMA. Since our phone does not have LTE, and very few T-mo markets have LTE, I found in some areas it would not register on the network at all until I changed the network preferences to one of the above because I presume the phone is trying LTE when the S2 doesn't have LTE. Also check your APN's? Just some suggestions.
You need a new phone perhaps then.
Seriously, with the new radio for T-Mobile or Telus, which are the only ones that work on all current roms (any others you've tried has been wasted time), and the correct apn settings, you shouldn't be having issues. Triple check radio is correct and apn.
You say your sim is fine.
So everything seems to be ruled out. And other than radio and apn, it can't be any settings, not after a clean install.
Phone busted is all that's left. Simple process of elimination. Well....if it somehow works on stock, but nothing else....then I guess your stuck with stock.
Thx.
P.s. getting snarky with people trying to help will certainly make most people, who may have ideas, just close the thread instead of trying to help.

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.

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
