[Q] LTE on CM10 tried everything

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.

LTE usage on non-LTE areas

I'm thinking about buying the s2 skyrocket, and as I already know, LTE drains the battery very fast.
The problem is that I dont have LTE in my country and I was wondering whether or not the LTE will still drain the battery even when there
is no LTE reception, by constantly searching for LTE network?
Thanx in advance!

No, just switch to H+

AT&T LTE phones don't have the option to switch to 3g or turn off LTE, so that simply won't work.

I'm guessing the phone is unlocked... If you can't get it to change manually by going into network selection and searching for networks manually, install a non at&t modem. (Rogers, Bell) than try again. If you are on stock touchwiz than you're SOL.
Sent from my SAMSUNG-SGH-I727 using xda app-developers app

It should let you as long as you aren't on touchwiz. Just go to the network selector, choose your network from the list, and then set it to GSM/WCDMA preferred. Or check use 2G networks only if that's what floats your boat. I'm on AT&T using AOKP and it just worked for me.
EDIT: Almost forgot, you have to redo it every time you reboot your phone.

It has nothing to do with TouchWiz. It's the modem. Use a non AT&T modem and you will be able to switch to H+ on a TouchWiz rom.

So many scenarios on battery life.
Signal strength, Apps, Wakelocks, brightness the list goes on.
You will have to play with it and give and take for your liking.
The best I've gotten was 3 days some odd hours.
Its a great phone you will not be disappointed.

So I'll just ask it differently then - Does the battery last a whole day (from morning to night) on non-LTE areas (auto brightness always on)
when only doing light-moderate use (just phone calls, texting, light apps like calculator, camera, playing a little music/videos, no gaming, no wifi, no internet)

LTE radio will not turn on if network apn doesn't provide it ..
So if network doesn't provide LTE , phone will connect to H+ if available ... No extra battery drain (from LTE) in this scenario.. I had a similar situation when I was on Starighttalk , they don't provide LTE , my location is an LTE market if I was using an at&t sim
Although it's a great phone , but it is getting old nowadays .. You might think of the international S3 maybe or an S4 .. Just my 2 cents..
PS :Custom roms aren't magic by selecting network preferred setting , you can do it in touchwiz with *#*#4636#*#* in dialer , but you have to use a RAT unlocked modem like the Roger's ones...

Does anybody get bad call quality, Because I read on some reviews that the call quality on the skyrocket is not the best...

[Q] LTE problems?

Been on the iPhone for close to a year. I'm tagging out! Coming back to android and the ultra or maxx has been the device I've set as my decision. However I'm a tmobile user. Maxx has the battery life I need so I want to clarify before I pick one up what any glitches of the device may be on the network. I've been reading with the kitkat update there is some sort of issue with the enabled lte and not being able to utilize SMS/phone at the same time as lte data? Is this true? If so any possible way to remain on H+ without activating lte or inputting apn settings? Or has this been rectified? Lol.....rectified.
Any input anyone has is appreciated. And yes I know. I should get verizon. I've been with tmobile for 12 years. I just can't beat their price right now and I live in an lte city. When I go out in the county it's a different story. But one day I'll jump ship. Maybe intervention is required. But right now I wanna stay with the T.

"LTE Thunderbolt" on the play store will be your best friend while on T-mobile
Works wonders with moto devices, you can choose which exact signal the phone should look for (LTE included)
Great phone period. On vodafone with it right now, used that app to ONLY look for HSPA+ and everything is golden Lemme know if you have any other questions, but that app should fix ya up

Awesome thanks bud. I was a but concerned about that whole hiccup and was making me second guess getting it, but the phone seems to be the best choice for me out of any available android phone. Hopefully this will get worked out. Do you find it a little inconvenient to switch signals or do you just stick with the hspa signal permanently?

That's disappointing. Unfortunately I just spent 400 dollars on one. Welp I guess I'll keep my fingers crossed. Glad I didn't trade my iphone off yet in case. Well I hope this can be tweaked. =\

You can switch the phone into gsm only using phone info. If lte is disabled you'll be fine on KK until they fix it. LTE/GSM works fine on 4.2. I'll link a copy of phone info to make the change. Please don't modify other settings as you can potentially permanently damage the radio. You'll get HSPA+ in refarmed areas. EDGE everywhere else.

Thanks for this! Are the odds pretty good that this will be taken care of in a future update? I feel like I don't expect it since it's not a verizon critical issue. Would this be taken care of in a future KK update or firmware? Thanks for your help so far everyone

I had talked to a contact of mine at Motorola and they were unaware of the issue til I brought it to him. It's on the list of things to fix.

You're doin it wrong GSM only disables the LTE radio.

If I'm understanding arcanexvi's post correctly it instructs to switch to "gsm only" and not "gsm auto", though it's circled in the illustration. Hard for me to speculate though until I have the phone in hand.

Lol you beat me to it. I can see the confusion though since gsm auto is circled in the photo. It's like sitting in the drivers seat getting directions from the passenger and they say left and point to the right lol. I'll let ya know how it goes when I get the phone. Thanks bud.

Cannot get LTE on my AT&T LG G2 only 4G

I'm running 4.4.2 on my LG G2 for AT&T
My wife just got the same phone and her phone shows 4G/LTE Mine shows only 4G
I checked our APN settings for both and they're the same
I checked through the 4636 code through the phone and it shows only the HSPA letters where hers shows up once again with LTE
ANY advice would be great

Try turning data off then on again, it will force it to search for the network.

Maybe replace it?
If this is a new phone that you haven't tampered with, I suggest that you exchange it. New phones don't need any change in settings to connect to LTE out of the box.
Maybe it's a hardware problem. Did this problem just appear out of nowhere? (maybe after the update)?

Update PRL to restore LTE???

I constantly get stuck in 3g and when I update the PRL, my signal will switch to LTE and work fine for a while. Is this common or do I have a defective phone? I went to the Samsung reps @ Best Buy and all he did was reinstall an update.

I would check which APN your phone goes to on the phone, Settings -> More Networks -> Mobile Networks -> click either Access Pint Names (to check which APN selected) or click Network Type (make sure automatic or CDMA/LTE, not just 3G).

Its set to CMDA/LTE and the APN is APN2 LTE (n.ispsn) internet. There are no other APNs.

Ok after some troubleshooting, it has nothing to do with the PRL. I can put the phone in and out of airplane mode and it will aquire LTE. Is this happening to anyone else or should I take my phone back for repair?

There's no way to repair it. I've had this issue since I bought the S5 at launch. This is just how it is until the towers are completely upgraded. Calling Sprint gets you no where most of the time about this issue. They will say the phone is defective but you can find many many ppl having this issue.

I had to pay $1.99 for full access, but there is an option to only cycle when on 3g. It does it all in the background, and doesn't really drain the battery. My only complaint is that it stays active and cycling while on wi-fi in a non LTE area. I've only had that in one place in KC, but no wireless service works at that location.

On 4G LTE, PRL's update automatically each time they connect to a tower. I think only 3G and earlier did you have to manually update PRL's. Correct me if I'm wrong, but I believe that's right. So technically, just cycling through airplane mode would update your PRL

my S5 won't receive calls or text
My S5 won't receive calls or texts. I spent hours with Sprint on the line, they were sending updates, having me manually program it and nothing. They would call my cell and straight to VM. They would send text, and i wouldnt get them.
I'm having to send it back, I'm not sure I will get another S5. I'm thinking a phone should be able to receive/make actual calls.

You are probably in an area that is in the partial stages of a Spark Upgrade. If you disable LTE bands 41 and 26 but leave LTE band 25 enabled, you will have stable data.
