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?

Thanks for replying. The apn settings are correct, ltemobile.son and the tethering one. This was one of the first things I checked. I'll add screenshots tomorrow if it's helpful
Thanks!
Interesting...got on LTE randomly...well sort-of

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...
Hello! I have an unlocked Galaxy Nexus on the Bell Mobility Network in Canada, that I have a US T-Mobile prepaid SIM card for traveling in the States, and getting cheap data: yay for $3/day unlimited talk, text, and data! I was away a month ago, and just noticed today, that I was unable to send picture messages. The phone said to check my APN settings, to which I said, "Wtf does that even mean?" and googled it. Upon figuring it out, I checked the settings, and it still had my T-Mobile info in there, not my Bell settings. I changed it, and everything is hunky dory, nbd.
My question is, why didn't it automatically change, when I got back to Canada and put my Bell SIM in? Also, when I got to the States, I had difficulty joining the T-Mobile network. It was stuck roaming on AT&T and I couldn't access data. I had to physically make it join the T-Mobile network, by going into the mobile settings, hitting network operators, and selecting T-Mobile from the list. I happened to figure that out on my own, purely by accident. I didn't have to do that, when I originally got the T-Mobile SIM during black Friday. I just popped it in, and it worked. My Bell APN settings were fine upon returning after Black Friday too. Does anyone know why the issue this time? I was only running the previous version of Jellybean back in November, the phone has since updated to new Jellybean, could that be why? Or is my phone crapping the bed?
Thank you for any input :0)
PS phone is unrooted and running stock Jellybean 4.2.1
Greetings everyone!
Signed up so that I can hopefully help someone else in need with their LG G3 phone using the Straight Talk 4G LTE Verizon sim card.
After many hours of flashing roms and trying out various things, it turns out for some reason other variants of the stock roms like Bliss Pop, CoudyG3, and Skydragon will not work with the data. I can still use my phone and make calls and i can still get text messages and even pictures sent through text messages, but for the life of me data would NOT work.
The only rom that did work again was the Jasmine rom. To my understanding it works pretty close to the stock verizon rom that comes with the LG G3. After the flash, BOOM! Everything worked and data came back to life.
I noticed the APN settings is very very different but this rom wont let you go in it to see it's settings. Surely there is a way to import/export the APN data to push on over to another custom rom? Just weird that after putting this specific custom rom data happily worked again.
BTW, if anyone tries to activate a verizon lg g3 with straight talk, be careful. Though their stupid website said that the phone was already registered with another tracfone provider/service, I was still able to get the phone to work. If after entering your MEID/EMI or whatever the numbers are and the straight talk website spits it back out at you, CALL straight talk. I got screwed and used up the network access code which somehow got lost into oblivion, but turns out that they themselves can manually add the Verizion 4G LTE sim card with the network access code card. (I bought the 4g LTE sim card package from wal mart). As long as the phone is in good standing, it will work!
Thanks. Hope this helps someone else out trying to get it to work with straight talk. I will try and see if there is a way to export this APN setting. I was told by straight talk that you don't need an APN set, but i think they are lying.
Peace!
solved
Back again,
Happy to report im using skydragon Rom with straight talk. Turns out you do in fact need to set the apn in the settings. Just add this apn
acct.tf.gw6.vzwentp
This is the apn for the Verizon 4g lte sim card when you use it. I didn't have to reset the phone but now data works great.
Hey question. I have a Straight Talk S3 currently running CM 11 kitkat based rom and things work great but I found other roms I want to install one of them being a Pac-Man custom rom but I have no data. I have a Verizon CDMA 4G LTE sim coming in acouple days just need the apn settings. Could anyone help me out with this? Thanx in advance for any help.
Sent from my SCH-S968C using xda premium
Surely it is the same APN setting as above. Try it out once you get your Sim card. Also, that S3 being a different phone may pick up on the access point names when you try another rom and set itself up, but if data is still not working, then try that APN I posted on the first post.
Also, be careful that you are actually connecting at LTE speeds as long as your area has it. Flashing to another rom I was only connecting at 3G. Turns out that once I tried another rom, you have to set the preferred network to LTE, then give the phone a reset. It took it a moment after reboot, but LTE finally showed up.
Depending on your phone, there are other settings to be set in it's hidden menu settings using the phones dialer. Just google around.
Hope this helps!
