(NQ)Can't Get LTE on AOKP rom on Rogers 1747M

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
phone information
set preferred network type
change to LTE/GSM auto

sorry not gerrit. you stated the info above in one of your earlier updates, which I did. Didnt seem to work for me though. Are there any suggestions as to how I can possibly fix the problem?

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

I747m telus network problem

I have a problem with my telus i747m, I have unlocked it and am trying to use it on rogers but cant. I have tried different sims.
My problem is I dont have a network connection all the time. When I do have a connection as soon as i get a text or try to make a call the phone looses the network connection, when making a call the call gets through but the phone looses connection and the call then gets cut.
no data connection at all. I have rooted the phone and tried flashing the modem posted in development section but it did not help.
do you guys think its a hardware problem, or software?
also when no network is connected and I try searching for a provider it ask me to insert a sim. I have tried different sims and both work fine in another s3 i have.

The phone has a strong signal when it connects to the network and then as soon as the 4g pops up or after a couple of seconds the signal just drops and loses the connection. Then it will keep on getting a signal and instantly drop the network connection over and over again. i have another s3 i can try swapping parts but i dont know what to swap.
hellpppp meeeee!!!

Ok i used rf nv manager andbthe imei is fine.

There is a specific Rogers modem that you can try flashing, other than that, I'm stumped.

lol yeah its a odd problem. ill try flashing that, the modem listed here http://forum.xda-developers.com/showthread.php?t=1831898 says rogers, telus, bell is this what you are talking about?
thanks

update so i was about to try flashing the modem again, i poped in the sim turned on the phone and noticed the signal wasnt dropping when wifi was connected. I then shut of wifi and as soon as the 4g symbol poped up the network connection dropped, I then shut off data and got the signal back i havnt lost it sinse and i made a 40 minute call to rogers with no issue; I have full bars.
so it seems when data is turned on the network gets disconnected. hope this helps in finding the problem.
i played with the settings a bit and this is what happen:
GSM only + data enabled = phone works fine
HSPA only + data enabled = as soon as 4g pops up network drops
GSM/HSPA (auto) + data enable = as soon as 4g pops up network drops
GSM/HSPA/LTE(auto) + data enable = as soon as 4g pops up network drops
all of the settings work if data is disabled.

I have just flashed the latest bell jelly bean leak and still the same problem with data turned on phone loses connection.

I have the same setup (Telus SGS3 with Rogers sim) as you but don't encounter that problem. You might want to try to use your warranty for the problem as it shouldn't do that on stock in the first place.

yeah i tried manually setting the apn too. didnt make a differance, also tried the rogers mvlle8 modem no differance basically the phone works with data off, or only gsm with data on.
I have another s3 i thought it could be the sim holder or something tried swapping that, it didnt change anything. do you guys think i should try swapping the antenna

its getting tricky to play with that unless you have a good knowledge about wat you doiong and that you may have no offense here
wat about the warranty ?

I bought it used and have already opened it up to try swapping parts wwith my other s3, also have flashed it with custom rom and im guessing the previous owner did aswell because the flash counter was at 5 I think ive voided the warranty. Im pretty good at taking things apart and not afraid lol. I was a mechanic so yeah.

Check your APN settings. On stock, when I switched sim cards, the secondary provider didn't have any and they needed to be added manually.

[Q] LTE Bell dies if using other roms?

I'm just wondering if anyone else has noticed this and this only happens after a period of time where the LTE will just stop working but if you switch to CDMA it's working fine?
To go a step further I've wiped the phone and restored to stock. Once that's done LTE is working fine.
To go further again, I grabbed a different ROM and the exact samething happens, I'll be able to be on LTE for about a day and then the service stops and if I switch it to CDMA I'm good.
Just wondering if anyone else here has noticed that.
Cheers,

did you verify your APN settings?
i'm using a Bell version GN2 but on Fido and i can flash all day everyday and 4g has always worked.

The APN settings are always the same with Bell. They don't change.
HSPA+ will work but LTE will die after a little while. (This only occurs on other ROMS). If I stay on the stock rom there's no problem.

On a different note... I noted that if I have SAMBA Fileshare on I have strange things that happens DATA wise.... I'm still looking into it and dropping logcat and looking at different possibility.
At this point it's looking like something with the SMB Fileserver I have on the phone. (Will know later on)

im not saying the bell apn has changed but ive found that sometimes when flashing roms, the apn settings arent included in the rom and have to manually be entered.

Tmobile S4 on AT&T cannot connect to LTE help!

Hey everyone!
So I picked up a tmobile s4 to use on ATT since I read it was the most unlocked due to bands / bootlocker. I unlocked it via the method described on this site via the debug menu.
Popped in ATT sim, everything looked fine initially.
1. I'm only getting 4G in an LTE area. device hasn't picked up any LTE anywhere yet.
2. When I go under "Network Mode" and select "LTE/GSM/WCDMA (auto connect) the signal dies out and it always reverts back to GSM/WCDMA"
3. I've called ATT a few times and triple checked that I'm on an Android LTE data plan, so that's not an issue. ATT techs suggested it could be a device issue and maybe I should take it into their tech center.
4. Tried to set up ATT Visual Voicemail, that failed also.
So can it be a Sim issue? Maybe something on tmobiles side? Since device was never active on their network. A lemon S4?
I've run out of options
Any help would be appreciated.
TIA!

i had tried some other rom. i even regressed it to the originally official rom. it was will EDGE. I wonder the possibility is that some important files has lost. but i didnt find any solutions.

These seem like pretty routine questions but have you checked to see if another phone has the same reception problems?
