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

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 many places stating that it is okay to run a T999 ROM on the T999L, so I gave it a shot. First with Hyperdrive (which wouldn't give me any internet at all) then with Dandroid which I am getting internet, how ever it will only give me H+ rather than LTE. I changed the APN to fast.tmobile.com, is there anything else I need to look for? I know in the about device settings it says I'm running a T999 rather than T999L.
Thanks!

Make sure that the baseband is still MB7 and you should be able to get LTE with no problem. Also, make sure that the "Network Mode" is set to allow LTE. Also again, the icon might NOT say "LTE", it might say "4G"
When you flash a T999 ROM the build.prop file lists it as such, but you can edit it to add the L with no problem. I do that (this is the reason that I stopped using the nightly builds, I got tired of changing it)

Awesome. I didn't know that. It does show 4G sometimes and sometimes H+. I do have MB7 baseband still and under network type it says LTE:14 so I guess I am good to go. My average download speed is between 10-14mbs. I just switched from ATT where it was 26mbs average so I guess I was assuming speeds would be similar between the LTE networks.

Nailed It!!
You got it exactly right, if the Network Type is LTE you are on LTE. The DL speed will increase closer to the tower with LTE.

And just so you are aware, there's a thread dedicated to the T999L that has this and many other questions answered. Links in my Sig, but it's usually close to the top in q&a.

This seems to be the only issue. Do I need to change some settings somewhere after flashing or should I just try to reflash the whole thing.

Look in your APN settings.
Settings, more, mobile networks, access point names, make sure apn is fast.t-mobile.com

T-mobile lte is selected and the settings are filled out. What could have caused the lte to stop working? It doesn't seem to matter what I do.
When I flashed it, network mode was set to 4G. Changed it back to LTE and got back my LTE.

Ok I am back on the stock rom and I am still stuck on the edge network and my apn settings are greyed out but look ok. The network mode is on lte/wcdma/gsm and the status bar says 4g but I have no signal bars and extremely slow spped unless I am on wifi. I can get calls and texts though. Anything else important to solve this?
Sorry for double post but my imei number is 15 digits long if that matters.
LTE GONE
Bump... Having the same problem! Tried everything with respect to network mode, APNs, *#2263# and flashing different roms.
Although it worked at first, LTE disappeared on me out of the blue. Any ideas?
Totally at a loss. Beanstalk, and 4 other newer os version roms I've flashed will not connect to LTE. The apn looks right. I even flashed the modem to the latest one. No joy... But if I flash back to cleanrom ace it works again. Any newer rom and only get H or h+. It will flash 3g for about a half second there switch to H or h+.

Does the APN say phone or pta ?
this is what i have to do to get 4g working. settings>more>mobile networks>network operator>at&t. After registering on at&t, i will be able to switch to 4g. this process may take a few tries and sometimes get stuck in searching....good luck

The apn called phone works for LTE on cleanrom ace but on every other rom it just does the same thing. Hits 3g for a second then switches to H.

I cannot select Att it's on default and will not change.
H is 4g H+is LTE. It depends on what rom base you have for what network speed icon you will see. It sounds like you are in an area with marginal coverage.
Just make a new APN, save it, then select it.
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.
