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
Rogers I747M

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

Hi
I have a ATT Note 2 with a t-mobile sim in it with ATT rom/modem/etc. The HSPA worked for like 2 minutes and never worked again. 2g works fine.
Has anyone gotten 3g/3g+ working one ATT note 2 on the tmobile network?
I know note works but couldnt find an answer for Note 2.
Please advice!
Thanks
^^^^^^ 2nd this.
ready to acquire GN2 ATT from local CL. but since i use t-mo cheap 5gb data plan, i am not sure how to benefit the plan. just a thought, you said HSPA worked for 2 mins (or so..) ? did you do any browsing/data usage and get result ? or just monitor the signal bar switching from H+ to E ?

I did a speed test and got 5mbps download. I also have the 5gb plan. There must be a way to get it to work!
Check and make sure your apns are correct.

Has anyone tried flashing a t-mobile modem?
Sent from my SAMSUNG-SGH-I317 using xda premium
I did - it gave me no service
Did you tried flashing a T-Mobile ROM??
yes didnt work either..
@ vish :
another shoot in the dark, do you think it has a relation with the phone being unable to toggle to 3G / UMTS mode ? will you please flash the t-mo radio back and tried :
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.

so with jedi ROM x 6.1.2, 4g signal stays intact ? can you please do speedtest & post it here ?
btw : this 4g signal, supposed to be H+ in t-mobile ? or is it just UI issue ?

Sorry for the late reply - i tried flashing tmobile model and I got either bootloop or no service. Even with the sim card out.
Any other ideas?
Are you sure you are in a refarmed area? Cause if not you will ONLY get EDGE
^^^ what he said. T-Mobile is refarming their network to be compatible with AT&T's 3G frequencies but only in certain cities right now. Check their website, it tells what cities. They may be testing in your area. Otherwise you'll only get edge because the note 2 can't do what the note 1 did. It's an exynos thing.

Has anyone tried this SIM card release thing to force 3G on t-mobile network on a AT&T Note 2 phone? did it work? or did I misunderstand this post to be a solution to getting 3G/4G on tmobile network?
Please help
Only edge will work. Get a t mobile device or switch to att.
Hi, Im using a model i317M, I modified it to work with AWS network, and the 4G icon on the task bar still showed up. Then I rooted the phone, and installed an international ROM (which is tested and can be installed for all models), to have a multiscreen function. After that, I can only connect to 3G network, the 4G icon is gone, and never showed up. I'm wondering what happened to it, and my network mode is still the same in the setting, which is "LTE/GSM/WCDMA(Auto Mode). If I installed the stock ROM will it come back? And can I do anything to get the 4G icon back without install any ROM? Thanks to you all! Really appreciated that in advance!
Some roms just don't have the 4G icon even when you're getting 4g.

If you are using International ROMs on your 317m, make sure they are based on 7105 and not 7100. The 7100 doesn't support LTE.
I am using ParanoidAndroid 4.3 on my Galaxy Note 2, I've notice with 4.2.2 and 4.3 that I can not access *#197328640#.
I need to access this in order to get LTE only, unless someone else knows otherwise. Please help. I didn't want to go back down to 4.1.2 Cleanrom.
Hopefully someone has a workaround, or if this issue has already been addressed, can you post link.

Im not 100% but i seen this asked a few times. I dont think about of the dial codes work for Aosp. And you can only pick up LTE in areas where your carrier has It. I know here in Jacksonville Fl its very spotty
I use lte only in Chicago. Works gr8 on Cleanrom 5.0 for skype while driving. Cant hve it switching to regular 4g. Might have to stick with that. Thk u

No problem bro. I never heard anyone trying only use LTE. I have heard alot of people trying to turn Lte off to save battery..lol... if you could lock it on LTE only than whenever you are away from an LTE area than you will have No data till you pick up LTE again.
Dont forget to hit thanks if Someone helps you​
Unless AT&T has implemented Voice over LTE (VoLTE), setting your phone to LTE only would leave you unable to use your Note II as a phone. Maybe you were looking at disabling GSM and EDGE instead, leaving you with WCDMA and LTE?
I only use my phone for Skype and google voice sms and calls & internet. I don't have phone service. I have an IPad 4g lte sim in my phone. I am able to do Lte only on 4.1.2. Not anything higher.
Would really like to use aosp or aokp ROM. But without that Lte only driving and talking going to H+ or H is Hell over Voice. Chicago has gr8 lte coverage.
Will probably have to stay with touchwiz.

Since i changed a new rom(cm11) for my unlocked i747, I could not receive any hspa+ internet(I am using h2o). at the begining, i thought it was because of the lost imei, so i fixed it, but it was not working. then i opened *#*#4636#*#*, and selected wcdma perfered, it changed to h+, but about 1 min later, it turned back to Edge. if i select wcdma only, I can use h+ 1min and then no more signal even edge. also cannot make phone call and texting. i dont know why. the APN setting is right. and anyone tells me what should I do. thanks very much!

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?
