You can get LTE on AT&T (if you are in an area that AT&T has LTE on Band 4), but the instructions in the first posts are not quite correct for any carrier other than T-Mobile.

Here is how:

First of all, you obviously need the following:

1) Be in an area that AT&T has LTE on Band 4;

2) An LTE data plan

3) LTE enabled on your account. (Some carriers require an IMEI number from a carrier-provided LTE-capable device on the account for your LTE plan to be enabled -- not entirely sure AT&T is like that, but I would bet.)

Now, assuming you have all of the above, this is all you need to do:

1) Flash a radio that is older than 0.48, i.e., 0.33 or 0.27, or 0.24. All of them will work, and all can be found in the radio thread.

2) Make sure you have the correct APN that AT&T uses for LTE set up (and selected) on your phone. (The first post says that "everyone" should do the APN part, but the info in there is only for T-Mobile.) I'm not sure what the correct APN for AT&T is, but I'm sure you can easily find it.

3) Then, just go into into the phone setting (*#*#INFO#*#*) and select LTE/GSM auto. (Selecting LTE/CDMA/GSM does not do anything different, as the N4 does not have a CDMA radio...).

By doing the above, you should get LTE on your N4. Note that the "LTE/GSM auto" setting won't stick after a reboot, but you can easily change it back. (If you want it to stick, then you will have to edit the build.prop.) If you cannot hear audio when making a call while your device is set to LTE/GSM auto, then you can try the settings in the first post that are labeled only for T-Mobile users (or just flash this zip).
[Nexus 4 General] Knight-Rider:
Like I said several post back this has already been tried it does not work. Unless you can prove it works otherwise let us know.
[Nexus 4 General] efrant:
Hey, believe what you will, but other users on AT&T have managed to get it to work.

Here's just one of many examples.

[Nexus 4 General] Knight-Rider:
That's 7 people including your previous post call it luck, pm them see if it's still working for them, they were in areas where they were able to pick up the necessary band again call it luck. Still doesn't prove the fact it's 100% working on AT&T.
[Nexus 4 General] efrant:
You can call finding those posts luck, but I'll call it searching. (There's more posts by the way.)

In any case, I'd be happy to guide you through the setup if you'd like.

Do you have all three prerequisites from my post (a band 4 signal, an LTE plan, and an IMEI from one of your AT&T LTE devices added to your account)?
[Nexus 4 General] Knight-Rider:
Lol I've been rooting phones probably before you were a squirt bud but anyway if you searched my prev post band 4 where I live is slim to none, I have 6 lines all on LTE plans I'm coming from a Note 2 but you probably failed to see my sig ;)
[Nexus 4 General] efrant:
If the band 4 signal is slim to none, how do you expect it to work? LTE on the N4 only works on band 4.
[Nexus 4 General] tarroyo:

OP here. I'm baffled by Knight-Rider's ignorance. Telling a forum mod with over 5000 thanks that he doesn't know what he's talking about is just.... ugh.

Props to efrant for being cool about it. There's a reason he's a mod and Knight-Rider is a.... knight-rider.

It just sucks that my thread has kinda denigrated into this. Try to help some people out and this is what we get...
[Nexus 4 General] XupModz:
Please explain how that's not proof and it doesn't prove it? The nexus 4 supports band 4 so ANY Carrier with band 4 support will work if that band is in your area, just because it isn't in your area doesn't mean it isn't in anyone else's
[Nexus 4 General] mih_:
confirm

Same here, with no gps/wifi location could not be determined.
[Nexus 4 General] mgorman:
Same thing with me. Have you found a fix this?
[Nexus 4 General] JDMFanatic:
After following these instructions, I get 4G perfectly, awesome speeds, but my problem is also getting location locks with 4g on. GPS and location service both dont work with lte on, and with LTE off only location service works, but gps doesnt get a lock. Weird...
[Nexus 4 General] BrianDigital:
No one said its 100% working on at&t just in areas that they deployed band 4 for their lte
[Nexus 4 General] Pichingo:
Had both issues on tmobile here in nyc. Couldnt lock my gps with lte and couldnt find location with just wireless while gps off

I downloaded the gps test app from the market free version.went to option clear gps and update gps. Restarted my phone. Now with LTE my gps locks and when i have gps off, wireless can be use to pin point location. Got gps lock in 6 secs inside my apt

Stuck on boot

I followed the instructions as follows and I went to reboot and I am stuck on boot screen. I am running PA 3.65 and franco with the updated radio flash for this rom as I am on t-mobile. I apologize for the ignorance on this issue. I have been able to get everything to work while messing with my N4 aside from this. What did I do wrong? Thank you.

Edit: I flashed .33 and all is good.
[Nexus 4 General] uploder:
just to confirm, following the steps in the OP do the settings stick? or will I have to do something upon every reboot? im on rooted stock , dont plan on running any custom roms
[Nexus 4 General] isra_sil:
Ok thank you
[Nexus 4 General] uploder:
I was actually asking not confirming lol
[Nexus 4 General] sylentprofet:
As posted, the steps stick for me just fine. I've rebooted dozens of times and 4G is up automatically.

However, I am using XenonHD for my ROM, and haven't tried any of the others.

In theory it should work, there's just an extra step in stock ROMs as mentioned a few posts back.

The "Network Selection" menu under Settings>More... is nonexistent, so you have to dial *#INFO#* from the Phone and select "LTE/GSM/CDMA" from there. Only do this once, and then try restarting, as from what I'm hearing it seems like going back into that menu resets it to WCDMA somehow.
[Nexus 4 General] jin512:
GPS Not working
[Nexus 4 General] mih_:
LTE on Tmo definitely works and usually faster (at least upload) than H+

The setting survives reboots in my case (i'm on cm10.1) with the instructions provided in 1st post (thanks!).

But there's some payoff:

1) no "wireless networks" only location (with no wifi&gps location could not be determined and if it works it's just rather already cached)

2) in a few days of testing i experienced at least twice problems when there's mobile connect, but no data can go through (gray signal in status bar). I remember similar android bug years ago when switching between mobile data and wifi and it resembles it's resurrection - the only workaround is reboot.

Also, it's worth of mention that the enabled lte doesn't improve the coverage. If the device did not work with 3g in some area, it would not get connected with LTE as well.

I'm still on it though.
[Nexus 4 General] jin512:
I'm still on it too. Even though the things you mentioned don't work for me either, I still feel that LTE is too good to pass up when it works well. Only thing I'm worried about is battery life. But yeah, it's like once you try LTE, you can't go back to only HSPA. Haha.
[Nexus 4 General] hochengsoon:
Stock N4 on 4G network

Pls bear with me coz I'm a noob on this topic.

Can stock N4 be used on a 4G network (just upgraded with bundled S4 but S4 for my wife)?

Will the method mentioned in this forum work with any telco LTE? I'm on Hong Kong 3HK (Hutchinson) network.

If not I must downgrade back to 3G network. :crying:

Many thanks in advance.
[Nexus 4 General] Dungeon47:
Battery has been similar for me. Over the past few days it's been a marginal, but not invisible, difference. I'd estimate an extra 5-10% over the course of a charge, perhaps less.
[Nexus 4 General] namurt:
i'm curious about this as well. i'm also on solavei, but i'm too lazy to try it out for myself. if it doesn't work, i don't feel like the hassle of switching back. :p

so has anyone tried this on any t-mo mvnos?
[Nexus 4 General] MandoH:
In LA trying out LTE...:D:thumbup::cool:
[Nexus 4 General] MandoH:
Speed test. :D
[Nexus 4 General] minieod:
i tried it - were outta luck until solavei opens up lte support.
[Nexus 4 General] namurt:
awwwwww :(

i had a feeling it would work out that way. another question out of curiosity, what solavei apn settings are you using?

i'm using these: http://androidandme.com/2012/12/news/how-to-setup-the-nexus-4-and-google-voice-for-solavei/

although, my n4 had default t-mo apn settings out of the box, and those worked too. i figured it was better to go with solavei specific settings. i think the settings posted on the official solavei support page are even a little bit different than the ones on androidandme.

EDIT: my apologies to OP for de-railing a bit.

I've been able to successfully get LTE working in the Cleveland area. However, when I have LTE activated and someone tries to call me they go straight to voicemail. My phone never rings. If I go back to WCDMA preferred incoming calls work just fine. Has anyone else experienced this? Outgoing calls work without an issue with LTE enabled.
[Nexus 4 General] Maine_Coon:
It works on rooted stock, however, after every reboot you need to do *#*#4636*#*# and change WDCMA to LTE/GSM/CDMA auto.

[Nexus 4 General] hochengsoon:
Damn, I guess so... Anyway I've at least manage to change the APN therefore my N4 continue to work on 4G network.

is that for nightly builds only?
[Nexus 4 General] Dungeon47:
Any nightly after the last "stable release" since privacy guard was put in.
[Nexus 4 General] mih_:
Last cm n4 release for today is stable - 10.1.1

But it seems there's no privacy guard, they told to keep it only in nightly build and asked for no bugreports for awhile

[Nexus 4 General] Deivore:
No LTE connection after following directions AND HSPA+ data wont stay connected!

I'm having a problem...

I've followed the directions word for word (or so I thought...) and things are working worse than before!

Not only am I not able to connect to LTE, but now I'm getting disconnected from(and occaisionally reconnected to) HSPA (even when it stays connected it rarely has the "+"). If I reboot the phone the connection comes back, but it usually only last a few minutes. During the disconnect there is no data, but I am able to make calls. The phone reports one bar of service, but the voice quality seems fine.

I'm on T-Mobile, and I did follow the audio fix directions.

I'm using the newest version of Paranoid Android Holo beta

I'm located in New York City, which T-Mobile announced yesterday now has LTE coverage.

In *#*#*4636*#*#*/Phone Information I'm set to LTE/GSM auto (PRL). If I go to LTE only I have no connection whatsoever.

Thank you SO MUCH to anyone who may be able to shed some light on these problems for me.
[Nexus 4 General] efrant:
This has happened to me on occasion. I don't know what's causing it, and I can't replicate it, but it does happen once in a while.
[Nexus 4 General] sylentprofet:
I don't know if I've experienced this or not, but I'll keep an eye out. Stock ROMs seem to be a little bit finicky with this workaround.

I'm using XenonHD currently and it seems to work well on T-Mobile's 4G out here in Northern California.

If a logcat or something similar would be possible I'd be interested in looking at it.

Good luck!
[Nexus 4 General] hwarfnugen:
I'm using CM 10.1. It's interesting because when I get a call I can see the 4G go to 3G in the notification bar, but the call still goes to voicemail. I'll play around with it some more this weekend. Thanks.

[Nexus 4 General] nyijedi:
I think I'm having a similar problem. When set to LTE/GSM/CDMA, I'll lose my data connection. I'll have full bars for voice, but no H or 4G logo. I have to go back to WCDMA preferred to get a data connection again. Anyone else experience this?

[Nexus 4 General] Hypoxic1:
LOL @ :beer:

When you say EVERYTHING, does this mean it falls back onto H+ & H just fine? How about phone calls when on LTE? Do you receive them/voicemail? Can people hear you & you hear them? What about rebooting?
[Nexus 4 General] lazer155:
When searching the snd_soc_msm_2x blahblahblah file, I see an instance of ACDBID 81:1, ACDBID 7:1, ACDBID 91:2, and ACDBID 6:2. Has anyone else had that problem? I didn't add the ACDBID 6:2 or ACDBID 7:1 parts. They are just there. I previously tried the all in one LTE enabling zip in another thread but later restored from a nandroid backup that I made before flashing that zip. Shouldn't the nandroid have overwritten the modified file since it was made before I flashed the LTE zip?
[Nexus 4 General] Hypoxic1:
Are you able to connect to 2G and 3G (H and H+) okay? Do calls come through and are both parties able to hear each other? If so, don't mess with the file. This will also make it a bit easier to enable LTE in the future, if you wish.

You don't really need to backup from a nandroid. Just go in & change the few things in the sound file & build.prop. You can also try Build.prop editor from the Play Store.

OH! Which ROM are you using? I think some of those custom ROMs include the proper coding for LTE. I'm on stock.

Absolutely everything works! I'm going to be flashing the new PA right now I'll let you know if it sticks.

If anyone is using XenonHD as their ROM and is on T-Mobile, the only change that needs to be made is selecting LTE/GSM/CDMA under Mobile Networks.

I've pushed the rest of the changes to the TeamHorizon github, so it comes ready out-of-the-box for LTE action.

Let me know if there are other ROMs anyone would like me to submit github push requests for LTE functionality.
[Nexus 4 General] lazer155:
Yeah everything seems to work fine (calls, all data 2g, 3g, H, H+). I had made and used the nandroid because I thought it would be a bit quicker than modifying everything back to the way it was. I would have kept LTE but I don't seem to get any in my area even though Tmobile is supposed to have it here.

I'm using CM, the latest nightly. I think you're right, CM does have LTE support built into the build prop but the official builds have it disabled by default for the nexus 4 since it isn't an approved LTE device.
[Nexus 4 General] Hypoxic1:
Okay, so now you know why those values were in the sound file. :o
[Nexus 4 General] Xxderek0822xx:
When I installed the new ROM I did have to make a couple changes. Minor stuff though. I just flashed the no audio zip. And had to change build. prop from lteoncdmadevice=0 to lteongsmdevice=1. I'm not a hundred percent positive that's how it is on there but it's something like that

flashed cm10.1.2 update over.

Radio .33 left untouched, but build.prop and /etc/snd_soc_msm/snd_soc_msm_2x_Fusion3 were overwritten.

Nevertheless, lte is still working!

It seems telephony.lteOnCdmaDevice=1 in build.prop just initializes it in baseband and persists reboots then, and makes "network mode" in settings to appear.

Without any modification of snd_soc_msm_2x_Fusion3 i can still make and answer calls with no audio problem on T-mobile.

not sure if i had this problem before though, i followed the instructions and modified the file before tried lte for the first time.

Nexus 4 Questions

I am writing to you because you are in the SLC area as am I.

I have a Nexus 4 as well but it is not rooted. However I did not install the most recent 4.2.2 update in order to maintain access to TMobile LTE when it rolled out. The update is sitting there on my phone but I have never installed it because I wanted to use LTE which I read you could do if you still had old radios prior to the most recent 4.2.2 update.

However, when I enter *#*#4636#*#* and go into phone info and switch to LTE only (just for testing purposes) I get bars but they are greyed out/not the usual blue. I seem to get an LTE signal bars but my phone won't actually let me connect to the LTE and use data.

There is no option under phone info for WDCMA/GSM/LTE only CDMA/GSM/LTE.

What else do I need to do (without rooting) to get LTE operational on my device?

I would prefer to just keep things stock and access LTE if possible.

Any help would be appreciated.

Thanks
[Nexus 4 General] eqjunkie829:
I believe you need to modify more than just network preferences and apn to get it. Build.prop hacks and a couple other things are needed because this wasn't supposed to be a lte phone in the first place. You can still root and not flash a custom rom to make it work though.

Change/add a new APN for fast.T-Mobile.com
[Nexus 4 General] alpine80:
Just an FYI.

Did some more googling. Found out I needed to change the APN to "fast.t-mobile.com" instead of the default TMobile APN. Then I switched it over to LTE only (just to test) under phone info. Bam!! LTE speeds at double my HSPA+ speeds so now over 18Mbps down vs 8-9 down previously. I also now have 4G above my bars in blue instead of the H for HSPA+.

My device is stock 4.2.1 because I never updated. I have not rooted or modified anything.

LTE will work on stock Nexus 4 devices as-is.

Thought I would pass along for others.
[Nexus 4 General] alpine80:
I googled and found your suggestion as well. It worked.

I can get LTE at 18+Mbps down now which was double my HSPA+ speed.

No rooting or flashing required.

So what is the best setting (on stock device) under phone info so it will use whichever network available including LTE? I'm guessing the "LTE/GSM/CDMA auto (PRL)"

Thanks!
[Nexus 4 General] kpjimmy:
When you go into *#*#INFO#*#* LTE/GSM auto is what you is chosen. The CDMA doesn't pertain to Tmo IIRC.
[Nexus 4 General] efrant:
LTE/GSM auto is the correct setting. It uses LTE and WCDMA and GSM.

http://xdaforums.com/showpost.php?p=40111542&postcount=387

You don't really need to do any of the build.prop changes. As a minimum, you need three things: a radio older than 0.48, the info for the proper APN for your carrier, and LTE/GSM selected. If you are on T-Mobile, you will also need to modify the sound file.
[Nexus 4 General] mih_:
I found LTE/WCDMA most useful for me.

With edge/gprs data practically doesn't go through anyway, and eventually 2g turns on instead of weak HSDPA

I'm on Tmobile in bay area with unchanged sound file and phone calls work perfect for me.

I assume it should be modified if it doesn't work.
[Nexus 4 General] efrant:
That option does not exist on a stock ROM. Must be a feature of your custom ROM.

I have Cyanogenmod installed, and i followed instructions to the T. LTE sticks and works perfectly but i seem to be having a problem with my phone's mic. It works sometimes, and then seemingly for no reason the mic stops working.

I'm not sure about anyone else; but I found these directions to be off a bit. I'm using Nexus 4 on T-Mobile; rooted running CM.

1) In my build.prop I switched: 'telephoney.lteOnCdmaDevice=1'; it was set to 0. I had no entry for 'telephony.lteOnGsmDevice" in my build.prop (this is the same a friend found and did to make his 4G LTE work).

2) I flashed the .33 baseband radio.

3) I dialed '*#*#4636#*#*' and switched "Set preferred network type:" to "LTE/GSM/CDMA auto (PRL)".

4) I went into the phone Settings -> Mobile networks -> Access Point Names -> Selected T-Mobile US LTE (fast.t-mobile.com)

Bam, 4G LTE kicked on and no audio issues at all.

Just my experience; thought I would share.
