(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

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!

[Q] ported sprint s3 to straighttalk but no internet

I ported my Sprint Galaxy S3 over to ST with the BYOP program. Calling and texting are fine, I can even receive mms but I can't send out mms and there's no internet connection. I've been on the phone countless times with ST, they always tell me to update my profile and prl..... which is strange because my 3G signal pops up when updating but disappears when its done. Can anyone assist me with this issue? Do I have to update apn settings or something?

Those are for phones with SIM cards, my phone is a CDMA phone. Will it still work the same??

I wasn't directing you to the Sim card solution per say. I was thinking maybe, some of the other trouble shooting options might help you. Have you tried Updating the APN Settings ? You could try ##72786# , but I'm not sure if that will work on ST.

Yes I changed the APN and dialed ##72786#, the 3G sign popped up for updating but disappeared once it was done

So can you actually access the internet ? But have no indicator that your connected. Or you have no data at all ? Can you send SMS / MMS ? What Rom are you running ?

Yes through Odin. But even before I rooted my device and didn't change the APN..... the same thing happened.

Sounds to me that your APN is not set correctly. Have you double check it. They offer a guide on how your APN settings should be. I had to do that with my brothers AT&T GS3 and after I set the APN I had to call them back to give them the serial # of the Sim card for them to activate it and then restarted the phone and everything works.
Granted it was a GSM GS3 but jus trying to help.
Did you have it programed to Straight Talk or did you go to their website and have them to set it up?
Be now I noticed they offer CDMA service byop. I was thinking of trying that this Friday

Honestly if you need to ask you probably wont benefit from it. But you can change the default tether apn to fast instead of pcweb + 3g + mega apn pack. I need ipv4 for my vpn to work properly and not leak my ip but there are lots of reasons to use ipv4 instead of ipv6.

This is awesome. could you possibly add lte/wcdma to the network modes? I can get the option in the hidden menu through the dialer, would love an option for it in the network mode menu.

Probably not unless you are only seeing 2g and 4g lte if that is so you will see e/3g/lte after flashing this. but you can just go in the build prop and edit that in. I will try to update the op tonight with details but probably wont get to it until tomorrow. I guess if you already see e/3g/4g you will get a lot of apns from around the world with this package.
*Edit*
can you get ipv4 apn to work properly with this phone on att? I dont mean ipv4/ipv6 but the real ipv4? if not that would be another benefit for you if you care for ipv4.

It shows ipv4 in the APN, but I never see 3g, just LTE, 4g, and a couple times 2g.

This should help out with VPN and torrents. Checking it out now!

Does this removes the 5GB cap of tether use on T-Mobile ?
Thanks

VPN works now, that's awesome. Still not able to download torrents though, oh well. Nice work!

Hay boss do you have to make the changes to the build.prop for this to work? Reason is it cause poor signal and 4G to drop in and out. At least it does on my device. Had the same problem with those edits on the G2.

No 3G bug since I flashed this last night.
Last night I noticed my tether is broken, but I didn't know why. My computer will not connect to the hotspot and will complain that the signal is low.
I did some debugging and found this:
I/hostapd ( 3179): wlan0: AP-STA-MAX-REACHED
The phone is not allowing the client to connect because it thinks the max has been reached. It's not a build.prop thing, I couldn't find it there.
Doing some more digging, I found that the hostapd.conf file that is generated when the hotspot is on (/data/misc/wifi/hostapd.conf) has max_num_sta=0 even though I have set it to 8 on the Settings Menu. I have changed the settings to something else and this always comes up as 0.
I also see some errors about some config files not being setup properly:
Code:
E/hostapd (31402): Configuration file: /data/misc/wifi/hostapd.conf
E/hostapd (31402): Invalid MAC address '/data/misc/wifi/hostapd.accept' at line 1 in '/data/misc/wifi/hostapd.accept'
E/hostapd (31402): Line 15: Failed to hostapd_config_read_maclist '/data/misc/wifi/hostapd.accept' at config_file.c
Not sure where this config_file.c is, probably in the code of the hostapd binary.
I don't think I had seen hostapd being used in the stock tethering, but I wasn't really looking for it when debugging previously.

The stock firmware has a hidden tethering APN, which is pcweb.tmobile.com. Using this zip allows you to change the tethering APN. If that one is configured as fast, then you should be good to go. Is your tethering working with this patch? Mine isn't

No mobile data on LTE

Hi,
I have a problem with my LG G3. I can't connect to mobile data, while network is connected to LTE. On LOS 14.1 everything is working fine. But on any stock ROM (v21a, v21c, v30b, v30d, v30n) phone is connected to LTE, but mobile data doesn't work. On CDMA only I have mobile data through 3G+ or H+. Reflashing through LG UP or flashtool doesn't help. Any suggestions? On custom ROMs LTE is working flawlessly, so it is clearly software issue.

Also enabling or disabling fast dormancy didn't help.

I found that the Access Point Name (APN) defined for my carrier on the phone didnt work. I had to manually define it - after which mobile data worked.

The simple answer is - some or all LTE bands are disabled. You have to enable it. To enable it:
1) go to play store and download "Network signal guru".
2) open the app with an active internet connection.
3)tap on the 3 dots on the top right corner.
4) tap on band locking.
5) tap on lte.
6) select all lte bands. Done.
No reboot required. If the network bars still don't show up, then reboot your phone.
Also make sure that you have the proper APN.

I have the same problem. I want to fix it without root.

All LG phones come with a hidden menu. To enable lte bands there. If it still doesn't work, try resetting network settings.

I bought an LG G3 about 6 months ago. Everything was great and everything was working until I rooted and changed ROMs to Fulmics ROM 5.6. I got back to stock (30b Global), because I didn't like it and I discovered that my LTE isn't working. Like I mean GSM/WCDMA provides me Internet but only (H and 3G), but when I switch to GSM/WCDMA/LTE auto it doesn't even try to connect to the internet. I flashed cyanogen 13, and other AOSP roms and guess what?! I had LTE. So then I thought, that if i have it on custom roms, i need to have it on the stock one. So I flashed about 5 versions of the stock rom and still no luck.
I still have guarantee, but will they do something else then reflashing the stock?
I've also messed about in the Hidden Menu with those fixes that I found on XDA Forums, but still.. No luck at all.
I really want to have fast internet (My carrier supports LTE, and on the box from the phone it has "LTE" on it. Is it possible to be a hardware problem or software? It's soo slow that I can't even upload this.
Also is there any way of fixing this issue without Root?

I bought an LG G3 about 6 months ago. Everything was great and everything was working until I rooted and changed ROMs to Fulmics ROM 5.6. I got back to stock (30b Global), because I didn't like it and I discovered that my LTE isn't working. Like I mean GSM/WCDMA provides me Internet but only (H and 3G), but when I switch to GSM/WCDMA/LTE auto it doesn't even try to connect to the internet. I flashed cyanogen 13, and other AOSP roms and guess what?! I had LTE. So then I thought, that if i have it on custom roms, i need to have it on the stock one. So I flashed about 5 versions of the stock rom and still no luck.
I still have guarantee, but will they do something else then reflashing the stock?
I've also messed about in the Hidden Menu with those fixes that I found on XDA Forums, but still.. No luck at all.
I really want to have fast internet (My carrier supports LTE, and on the box from the phone it has "LTE" on it. Is it possible to be a hardware problem or software? It's soo slow that I can't even upload this.
Also is there any way of fixing this issue without Root?

I too had the exact same problem, until I discovered an app called 'network signal guru'. Go check it out. It'll definitely work.

I tells me that i need to root. I dont want to do that, any way to do it without?

On Fulmics there is also no LTE. LTE works only on AOSP/CM ROMs. What the hell?

I'm assuming that you have full network bars and you only cannot access the internet.
Accessing hidden menu comes in use ONLY when no network bars are appearing after changing from GSM/HSPA to LTE and it also requires root.
If you ONLY cannot access the internet but have full network bars after changing to LTE, you have to change the APN in settings. APNs are carried specific, so they differ from carrier to carrier. APNs act like a gateway between the phone and the internet. So, APNs are necessary in order to use the internet.
To get your APN, open Google and search "apn settings for [carrier name] 4g"

If you're already rooted, use the app 'network signal guru'. Download the app, open the app, tap on the 3 dots on the top right corner of the screen. Tap on band selection. Tap on lte. Enable all lte bands. Done.

Changing APN's and even after rooting using this app didn't help. I am sending phone to repair, because it's still on guarantee.

First try claiming a replacement for your sim card. If it still doesn't work, ask for a replacement for ur phone itself.

With new SIM card the problem still exists.
