[Q] LTE on CM10 tried everything - AT&T Samsung Galaxy S II Skyrocket SGH-I727

For some reason I cannot get LTE to work at all on CM10. I've done everything and it still wont work at all. I tried reverting back to stock rom, and when I did, LTE worked. So I thought if I went back to CM10 from stock it would resolve the issue, but it did not. I've checked my APNs and I cannot change the preferred network mode and i tried *#*#info#*#* and i can't change anything there to anything that has LTE on it. I'm not sure if it's just a problem with the ROM or what, but I've done plenty of researched, searched all the forums, and can't find anything that will fix.
Additional information:
Im in ATT
I've tried all the radios
and I AM in an LTE area.

Just making sure, but you know the LTE icon doesn't exist in cm10 , right? LTE is indicated by the 4g icon

Ok, try different apn. Which cm10 are you trying to use?

Does the problem happen on other ROMs? I'm not saying to use a different ROM, just saying that if it doesn't happen on, say, AOKP or Orthus (both CM-based), it's probably an issue with how CM10 is configured on your phone.

If you go into network operators (settings -network)and select att it will allow to change modes.

Haha yeah most of the time this setting is overlooked and this option enables you to turn off LTE if you want (which you don't have to have a RAT unlocked modem as presumed) and if you go to *#*#4636#*#* on your dialer you can have it set to LTE only as well.

I actually have another problem now, after a reboot, it doesn't show any options for me to choose under available networks?
it came back after a few tries but then went away again, it's not consistently there to choose.

Does it show a searching animation?

I have the exact same issues. I've done everything on this post plus done all the research as well. For my problem whenever I enter an LTE area my data service completely drops for about 5 seconds and then when it connects it only shows HSPA+. I have never been able to pick up LTE. When I was on CM9.1 I had no issues at all. LTE connected with no issues. So is this a CM10 issue or a phone issue?

try this, might help, might not, make a backup, if you have more than one apn, remove all apn's except your lte apn(ATT Pta, for rogers :ltemobile), restart phone
edit: of course make sure it was set to the lte apn in the first place, if it was and still have probs, do above procedure if you have more than one apn

For some reason my APN was not set to the lte one (ATT Pta). I changed it to that. Hopefully that fixes my problem. Thanks for the help!

I have a slightly different problem. I am running the latest cm10 nightly and notice that any time I get lucky and go into a 4g coverage area I can only make phone calls. No data transfers at all. I have my APN set to ATT LTE pta which I assumed is the right selection. Im normally in a A3g(HSPA)~700-17 coverage area. Is this the wrong APN to use?

Do you automatically switch back and fort from 3 to 4g with that APN setting when you move around without losing data capability?

Yup. I have HSPA/HSPA+ around my house but close to work I have LTE. No problem with switching or losing data connection when I go from HSPA to LTE. Just double check your APN settings. There might be a typo or some missing field. Or you can create a new APN for lte and use that as your default.

@26.2man, you've gotta have att provision you for lte at the store or whatever if you haven't done so already. Then it should work.

Does the UCLA3 modem work for Rogers LTE?

I just switched to Rogers with an LTE plan and LTE SIM card, and my area is has complete LTE coverage but the best I am getting is HSPA+. Does the UCLA3 only enable LTE on the 700mhz band? If so, what is the best Rogers modem to use for LTE? Thanks!

To answer your question just make nadroid and flash it if it does not have LTE then you can clear out and always go back to ur Nandroid!

Does the nandroid restore the baseband? I know a nandroid restores everyhting else but you might actually have to reflash the original radio that you were on before the UCLA3 version...not actually sure though.
This radio is the best for Rogers everything work great, lte as well and reception is great. At work where I only sometimes got connection at all, I have min two bars now, and internet works perfect. Thanks for makers and uploader

i concur.
lte picks up where the rogers modem doesn't I go between that and the telus modem (which doesn't do LTE but has good hspa speeds) It also does a great job in just automatic mode selecting the right band for low signal areas.
Yep I use it on Rogers with LTE working.
Also, someone mentioned a fix where you dial *#2263# to change the baseband to LTE only.. which works, but I stopped getting incoming calls and couldn't make outgoing calls when I did that.. fyi. Maybe it was just my case.

Not only data uses LTE network. When I used LTE data plan I got missing calls sometime (the call went directly into voice mail). Called rogers and the tech confirmed that calls work through LTE as well. If the signal of LTE is weak the call then bounces back into voice mail.

i've been switching between LA3 and KJ7 modems past 2 weeks...signal seemed great on LA3, but i'm not convinced it's good for me....
Consistently past several tests I get 2-3Mb down and 0.5-0.8Mb up on LA3......and if I flash to KJ7 I get 2-14Mb down and 1-3Mb up.....flash back to LA3 and it changes back....and flash again to KJ7 and back to other numbers....
In my area, KJ7 actually seems to be better, and I've switched back for now. I'm mainly around HSPA, not LTE though...
It also seems to be giving me better battery life...albeit we're talking difference of maybe 30 minutes to 1 hour...this phone is a PIG when it comes to battery life
So I've been using this modem since yesterday and I haven't been able to pick up an LTE signal but maybe Rogers coverage map is incorrect? idk but the 3g signal has been great
The only problem I'm facing (which I'm not sure if it's caused by the modem or something else) is that I couldn't send a text message to anyone but myself cuz it would fail... but if that person sends me a text first, then I can start sending text messages back no problem...
I registered for Rogers One Number, does that have anything to do with it?
UCLA3 radio works fine for me and I'm on Rogers network.
To check if your problems are radio dependent, why can't you just flash back to the Rogers radio? I believe it is on the same radio thread.

I tried that twice but when I check under Status it still shows the UCLA3 and not the one I flashed.
Also, I keep setting to to GSM/HSPA/LTE (Auto) mode but it keeps switching back to the one without LTE
EDIT - For some reason the APN settings were only for non-LTE access. Changed the apn to ltemobile.apn and now it works

Lost LTE

I have ICS-SUPERLITE-4.2 on Rogers and i totally lost LTE. I wrote in many existing threads and dev section and no one answered.
I lost LTE, even in areas of full reception, i dont have it, i used stock APN and LTE APN and still dont get it. I do get 4G.
Other on rogers running 4.2 have lte, just less reception so im guessing radio is not the problem. Any idea?
mhx did say he broke lte in 4.1 so maybe you got something from that. im flashing now and ill see how it goies
well im on 4.2 so its supposed to be fixed
I was having lte issues on 4.2 aswell

LTE works fine. Just make sure it says ltemobile.apn instead of rogers-core. If it still doesnt work then go int the phones menu *#2263# and select option 4. After that go back into the menu again and select 1 for automatic.

I've had to use the *#2263# option to get LTE on every ICS ROM I have tried so far, works great but sometimes I have had to redo it after the 2nd and 3rd reboot for it to take...
Another solution is after you flash an ICS ROM is to have patience , if you wait 5 minutes or so after flashing, before even touching\unlocking the screen, then most of the time everything settles in nicely on its own.
if ur using rogers with the ics leaks, there's several issues. Call id and lack of lte being one of them. This issue is present with all of them, it is an unstable leal after all. i believe lack of lte unless near a strong connection is due to uclca4 issues.
well after doing what i wrote 2 posts above, i have no issues with phone except for reboot/power off hang, i also get the occasional 2-3 second lag but its quite rare. Besides, im very haapy with rom, battery life is much better than GB
no lte after ics leak
I've the same issue with AT&T in Miami which has a strong LTE network. LTE worked great with GB. After installing the ICS leak all I get is HSPA:11. When I go into *#2263# it says RAT Selection option is restricted. Anyone have a solution?

Probably don't have the correct apn. apn needs to be set to pta in order to get lte.

Ditto - well actually I AM seeing LTE, but a drastically reduced data rates. Does not seem to matter what ROM, or Kernel or how many times I have re-flashed or re-flashed just the ICS Radio, I get roughly HALF of what I was seeing on GB. Ugh. I don't WANNA go back to Gingerbread. I just want perfection. Is that too much to ask for?

It's not the APN, at least in my case. It just crappy reception, and it happened exactly when I flashed ICS, and has been like that ever since. This in spite of re-flashing the Olin leak, reflashing the the radio, etc. It really irks me, and I do NOT want to go back to GB

RAT Selection option is restricted
Just flashed SeanZ ICS 4.2A-7 ROM and i727UCAL4 modem. I'm still getting "RAT Selection option is restricted". There is nothing else on that screen. This has been 3 different radios now and I cannot get a screen that allows me to select the radio band.
Would flashing a different kernel work? Any other ideas?

[Q] Deactivate LTE on ATT Rom

Okay I have read somewhere that we can edit a file to deactivate LTE on an att rom ...

Thanks in advance

no it only turns back after you reboot...
Entering a new APN should do the trick. Not sure what you should use on Rogers or Virgin. But for AT&T, they have different APNs for LTE versus non-LTE phones. So entering the APN info for non-LTE seems to disable LTE.
That dialer trick doesn't work, all of the options not containing LTE revert back to the original right after you select them.

This may disable it but it doesn't turn off the LTE radio in your phone. It still searches for an LTE signal and still yields the same battery life.

Depends on your goal. If you are in a fringe LTE coverage area, this will solve connection problems, and thereby improve battery drain to some degree.
But I see what you are saying. It prevents connection to a certain LTE network, but doesn't turn off the LTE radio.

I did not have that issue when using the GPE rom no. Did you make any changes to the APN settings? Did you take it off of Global?

I have not changed anything on the rom, I had to change the sim card the other day because no matter what I was only on 3g and no LTE. all the settings are correct for me to have LTE. when I was in the Verizon store on Monday I checked there display phone and it is automatic set to global, even the rep there said that all these phones automatically set itself to global. when I change it to LTE instead of global I get no signal what so ever, and when I go to *#*#4636#*#* and change it to the lte/gsm/cdma I still get no signal.

[Q] Nexus 5 LTE doesn't. out of ideas.

Hey guys I bought this nexus a while back, and it has worked perfectly until yesterday.
I started out on Att then moved over to sprint with no problems. Well the other day I decided to try out some new ROMs. When I got the ROM itself on there (Crom) the WiFi didn't work. So I googled around found a fix. After applying the fix now my LTE doesn't work. I have to go into the settings and change it from LTE recommended to 3G to even get signal.
Things I've tried:
Reinstalling APN
Radio
Tried Spark settings for sprint.
Edit: I forgot to mention, I am running stock 4.4.3 now. I did a factory reset lock then re unlock to root.
Actually the only thing that seems to work is the 3G. If I set it to global I can't get calls or anything at all.
Anyone have an idea what's going on?
