Just a comment for those asking if it still works. LTE works fine with 4.4 on my N4 with both stock and purity. I did have some trouble at first, so I did the SQL edit for permanent LTE which worked great. The only downside is the effect on battery life.

[Nexus 4 General] Sfkn2:
Does tmo have LTE activated in your city?
[Nexus 4 General] sylentprofet:
LTE's working fine on 4.4. I updated the OP to reflect a couple small changes in the process but all is well.

I've released an LTE enabled ROM tentatively called "Stryper" (click here for the thread) so check it out if you're interested.

It's a lightweight version of AOKP, all unnecessary apps removed, ringtones/alarms, very smooth and stable. Approx. 30 MB smaller than stock.

All necessary LTE code changes have already been made, all you have to do is update your APN settings and select LTE in the INFO menu (*#*#4636#*#*)

Good luck everyone!
[Nexus 4 General] lotherius:
So, LTE hasn't been added to the Network Mode selections?
[Nexus 4 General] sylentprofet:
It's there, but now it's simply listed as "4G". In the ROM I'm using (Stryper, modified AOKP 4.4) if you go to Network Mode it lists 2G and 3G. Through the INFO menu you can enable the unseen 4G option. It sticks after reboot as well, so it's all good.

It's a little bit of a dirty hack at the moment, but it works. If a cleaner way appears I'll be sure to update.
[Nexus 4 General] TheRandom1:
Just followed these instructions on my AT&T prepaid account and it's working very well. Much thanks to the OP! Of course now that I notice Tmo has an unlimited everything plan for a whole $10 more than I'm paying for 2GB on ATT, I may have to switch the settings a bit very soon, haha.

T-Mobile Audio fix

The t-mobile audio fix link is down and my audio isn't working on 4.4. I flashed back up to the newer radio and I'm going to try one of the .27 hybrids. Any suggestions?
[Nexus 4 General] vn00914361:
I'm on KK4.4.2 based CM11 with .27 hybrid modem right now. Everything's working great!!!
[Nexus 4 General] sylentprofet:
Technically, the T-Mobile audio fix is only required for 4.2 ROMs. It has to do with a small piece of code. After that, the main source was revised and future builds are unaffected. Sooo, it shouldn't be that.

Try the 33/98 or 27/98 radios, and make sure you clean flash the ROM. Wipe data/cache first. Dirty flashes cause the majority of problems I see people having.

I have nexus 4 and I enabled LTE on my phone.

But now when I turn on Vonage it shuts off immediately

Can someone help?
[Nexus 4 General] vn00914361:
Contact Vonage Customer Service for more details
[Nexus 4 General] misterno123:
I don't think Vonage CSR can help me because It was working before the LTE enabled

So this tells me that the during the LTE enabling process something happened
[Nexus 4 General] :
Hello,

My Nexus 4 is running PSX 3.0.4 based on Android 4.4.2, I would like to activate 4G on this, but I don't know how to make that.

Someone can help me step by step on this thread or in Private Message ? Thank you !
[Nexus 4 General] sylentprofet:
"it" shuts off? As in, the entire phone powers down? Or LTE switches back to HSPA? I need a little more specific of an explanation.

Is Vonage an app or are you using it as like some home phone extension?
[Nexus 4 General] Kernel=Panic:
GSM or CDMA

The script in your zip file reads .telephony.LteOnGsmDevice=1

The tutorial reads LteOnCdmaDevice=1

Is this different for provider? I'm on TMobile and mine says GsmDevice.

Thanks

[Nexus 4 General] rasengan82:
Dunno about you guys but flashing the hybrid radio was enough for LTE to stick. LTE sticks even after reboots. I'm on 4.4.2 stock.
[Nexus 4 General] polzovotel:
Confirm - just flashed hybrid modem + changed manually to LTE/gsm. Sticks after reboot.

Purity ROM.
[Nexus 4 General] siafu2000:
Hello all.

Thank you for your posts in helping setting up LTE.

I'm in Seattle, (home of T-mobile) and was having some difficulties setting up the LTE.

I have the Nexus 5 experience rom running on my Nexus 4 4.4.2 phone.

My LTE, 4G or HSPA+ is not displayed with the signal bars, just Edge, 3G or HSPA.

However, when I do speed testes, while the display is HSPA on, the speeds are Download on average of 23Mbps and Upload on average 2.5Mbps

Reading a post here that gave a link to T-Mobile, these are 4G/LTE speeds.

But why is my phone not displaying the connections properly?

Thank you in advance.
[Nexus 4 General] polzovotel:
I think it is a ROM issue. Just try another ROM. I use purity and bars are displayed

.
[Nexus 4 General] siafu2000:
I see, thank you for the suggestion, might give Purity a try.
[Nexus 4 General] Magnet42:
In the *#*#4636#*#* menu, my preferred network doesn't have LTE/WCDMA/GSM Auto. It only has LTE/GSM Auto. I was wondering how I can get LTE/WCDMA/GSM Auto. I am on AOKP.

When I am on LTE/GSM Auto, I have a lot of drop calls.
[Nexus 4 General] bluesteve3:
I know it only works on Band 4 but is this a hardware or software limitation?
[Nexus 4 General] sylentprofet:
Hardware.

The radio in the N4 is capable of receiving 4G on band 4 only, and since that would limit the amount of markets internationally that the phone would "work" to full specification, the phone was released as "officially" only supporting H/H+/Edge bands.

Some clever boffins figured out by combining parts from different radios (hybrid) they were able to keep the latest updates but still maintain 4G functionality.

For the record, the easiest way to do this nowadays (if you are rooted, anyway) is to install the Nexus 4 LTE Modem Flasher from the Play Store. It really simplified the process compared to the flaming hoops we used to have to jump through.

Or for those of you Tasker users, some scripts! There are two for the build prop: LTE enabler, what looks like network optimizations(?), and one for the audio fix.

I have to re-enable LTE every time I reboot with *#*#4636#*#*. Is there a way to make it stay so I don't have to do it every time?
[Nexus 4 General] sylentprofet:
My directions don't require messing with the "INFO" menu (#*#*4636#*#*) and stays permanently enabled after reboots.
[Nexus 4 General] twitch330:
When I rebooted, I had to do that and change it back to LTE. It defaulted to WCDMA Preferred.
[Nexus 4 General] sylentprofet:
How did you enable it in the first place?

My directions make no mention of the info menu so I'm just confused as to how it came in to play.
[Nexus 4 General] twitch330:
Well, I flashed the radio, tmobile audio fix and the mako lte enabler zips. I noticed after reboot it was on 3G/H+ so I used info menu to check it and, I re-enabled it there.
[Nexus 4 General] sylentprofet:
I did not write the zip file flashes, nor do I endorse them in my original post. In fact, I explicitly said they did not work for me:

Try following the full directions in the OP and get back to us.
[Nexus 4 General] XupModz:
I did four things to get my lte working yesterday (I'm on stock rooted ROM)

1.flashed .33 radio

2.flashed T-Mobile lte enabler

3.edited sound files manually

4.changed network preference to LTE/CDMA/GSM(PRL)

I have to change it back after every reboot but that's not hard I know the dialer code by heart now :P
[Nexus 4 General] twitch330:
Okay, I did that and still have to change to LTE after every reboot. It's not that big of a deal though. I'm happy with faster speeds. Thanks for all the info!
[Nexus 4 General] danielt021:
Anybody else having problems with GPS while on LTE? When opening maps after a while I receive a message that location is temporarily unavailable but when I switch to HSPA it works flawless. Any thoughts? Oh and thanks for the guide it works nice although I too have to go *#*#INFO#*#* after reeboot as stock ROM doesnt have Network Mode in settings.
[Nexus 4 General] TonyStunts:
Does LTE tethering still working using these instructions?

edit:

ok, I followed the instructions exactly. I recently unlocked and rooted and flashed the .33 radio then followed the OP's steps. LTE tethering works fine. LTE does not stick when I reboot. One thing about the instructions in the end, "When you are back to a working homescreen, navigate back to Settings>Wireless and Networks>More...>Mobile networks and this time select Network Mode. It should say something like WCDMA Preferred. Change that to LTE/GSM/WCDMA." I don't have that option. I'm on 4.2.2 t-mobile USA. the only option it shows it "use 2g only" so I did the *#*#4635$*#* and changed the radio that way.
[Nexus 4 General] mmduluth:
It's weird that it's hit or miss. I followed the instructions exactly and LTE sticks on reboot so no issues here.
[Nexus 4 General] scott62185:

Hi a couple of questions

How did you know the line number? I had to read pretty much everything to find the lines you mentioned, once I tried to save the changes this error appears

Also let's say a finish editing everything, I guess i have to do it again after a new ROM flash?

Does the zip prop editor fix I saw in here works? Seems not.
[Nexus 4 General] sylentprofet:
ANYONE LOSING 4G ON REBOOT - PLEASE READ

Can one of you please check your build.prop file in /system and tell me if there's any lines reading:

ro.telephony.default_network=9

ro.ril.def.preferred.network=9

If those two lines are there, try removing them. When I was experimenting with enabling LTE on my handset, those ones would mess me up on reboots. Don't touch anything else though.

Let me know.

[Nexus 4 General] Chinpokomon:
I think you're right about this. I didn't add those lines to my build.prop, and I've not had any problems with LTE sticking. However, based on what those settings say, it seems likely they would cause the phone to switch to those particular settings on boot, which may not be correct...
[Nexus 4 General] ronnyhawks:

[Nexus 4 General] a5ehren:
I'm stuck on this step - I'm not seeing the Network Mode option in the Mobile Networks menu. I flashed the .33 baseband and verified that my build.prop change stuck, so it should be there right? On stock 4.2.2, did everything by hand, no zips.

Edit: Oh, NM. This menu isn't present on Stock ROMs apparently and the dialer code has to be used. OP should mention that.

You could flash a new radio but If you did the sound file edits you would need to change those back I believe, no need to worry about the apn

[Nexus 4 General] SilverSurfR:
Make settings stick.

I'm on the stock 4.2.2 ROM and got the LTE/GSM setting to stick on reboot by editing an sqlite database that stores system settings.

I did it from adb shell with sqlite3.

sqlite3 /data/data/com.android.providers.settings/databases/settings.db

then at the sqlite> prompt:

update global
set value=9
where name="preferred_network_mode";

I've noticed toggling 2G/3G breaks this, could be different on custom ROM.

If you're going to try this, make a backup. I figured out the SQL commands with about 5 minutes of Googleing. They could be wrong and have adverse effects I haven't experienced yet, you've been warned.
[Nexus 4 General] iStayHigh:
Do I need to flash the radio .33 for this to work because I'm on radio .27 and did all the steps but I still get H/H+ so Im guessing there is no LTE in my area yet. :mad:
[Nexus 4 General] SilverSurfR:
From what I've read anything before the .48 radio that came with 4.2.2 will work. If you're not near a big metro area it's likely there's no LTE, especially if you're on T-Mobile.
[Nexus 4 General] iStayHigh:
Yea I'm far from a big metro so I guess I'll just have to wait it out until T-Mobile has LTE everywhere.
[Nexus 4 General] nickslg:
can I add that my phone already displays the lte/gsm/wdcma without changing any of these settings
[Nexus 4 General] tjdouble07:
I have a question for anyone who may know. Under preferred network, when I am in LTE/GSM auto, and I start off with LTE (4G icon) signal, if I get a phone call the phone goes back into HSPA during the call and stays in H after the call has ended. I will then have to go back into preferred network, toggle the setting back to lte only, and after the phone is back in lte, the phone will stay when being put back into LTE/gsm auto. Is this normal? If so, is there a way to make it go back to LTE when the call is over? I both manually changed my build.prop and flashed the recommended .zips. Also, i am using .27 radio.

Any help would be greatly appreciated!

[Nexus 4 General] Knight-Rider:
This does not work on AT&T.
[Nexus 4 General] MichaelVeringo:
Any reason why?
[Nexus 4 General] Knight-Rider:
Easy it's not Tmobile, this only works on their network and there's been other threads confirming that it don't work.

The only thing that sticks is the build.prop lteongsmdevice=1 the rest doesn't. APN doesn't stick, flashing the .33 radio is useless because the LTE/GSM/WCDMA doesn't stick either. Thread should be changed to T-Mobile and possibly others exclusion AT&T. Try for yourself but didn't work for me and I have no problem picking up 4G LTE on my Note 2 where I live.
[Nexus 4 General] sylentprofet:
Someone on page 2 or 3 got this to work on Fido or Rogers, and other people are confirming success.

It may be that AT&T doesn't operate LTE on band 4. But I am confused as to what you're saying exactly doesn't "work" about this. Do you mean that it doesn't work at all, or that the LTE just won't "stick" after restart??
[Nexus 4 General] Knight-Rider:
Exactly that's Fido & Rogers I'm referring to AT&T. And all of the above nothing sticks or changes for that matter, no 4G or LTE or 4G LTE.

AT&T has VERY FEW band 4 LTE markets. Your chances of being in one are less than that of finding a needle in a haystack, apparently.

lte/gsm/cdma

Ok, so I followed the directions. When I switch network mode to LTE/GSM/CDMA it does not stick. If I go back into mobile networks and navigate back to this it has changed to LTE/GSM only and displays CDMA on the network mode screen.

Is this normal as I am in an area without LTE or should it stay on those settings?
[Nexus 4 General] epik277:
It worked for me with the flashable zip. I'm on tmobile in NYC. I'm kicking all these iPhone 5 users asses out here:D....no f%*#ing lie. I'm loving it ha ha.

And I switched from a gs3 with no regrets.
[Nexus 4 General] jcnbama:
So my baseband is showing 2.0.1700.48 So I guess that means I'm on the newest baseband. So does this mean I need to downgrade my baseband... Which I guess is fine. I just wanted to know two things.

1. Are there any weird side effects of downgrading the baseband? I don't wanna mess anything up on my awesome phone just to get LTE.

2. How much faster is it? Is it really worth messing with my build prop and all this? Just wanted a general opinion of that.. Thanks!
[Nexus 4 General] Dungeon47:
Flashable zips are working for me on T-Mobile. I do have to enter the dialer code after each reboot and re-select LTE (option 9) whether I have the option 9 lines in build.prop or not. I'm on baseband .33. GPS also works fine.

Update: Rebooted again after about an hour and dialer code settings stuck. I currently do not have the extra 2 lines in my build.prop, so there may be something more to that.

---------- Post added at 02:25 PM ---------- Previous post was at 02:24 PM ----------

No side-effects here. Speed difference will depend on LTE strength vs HSPA strength in your area. Make a nandroid and then messing with build.prop is painless.
[Nexus 4 General] jcnbama:
Thanks. I guess I'm just hesitant because I'm completely stock rooted with no custom recovery. Kinda liked the idea of getting an ACTUAL OTA for once.. Lol. So if I screw up the build prop.... Lol.
[Nexus 4 General] mgorman:
Just a heads up....setting the APN protocol to IPv4/IPv6 will cause problems with data connections in certain apps. Putting it to IPv4 will fix the problem and won't cause any lower speeds
[Nexus 4 General] cocreateguid:
Okay, I made the changes as OP directed (except the last step - had to use the *#*#4636#*#“ code) and I get 4G connection now. Speed Test is giving me download 33.08Mbps/upload 21.31Mbps. Pretty good.

Only thing keeps it from perfect is I have to call up the PhoneInfo screen and select LTE after a reboot.
[Nexus 4 General] rezendevous:
To make it stick permanently (even after reboots) follow the steps here:

http://hippowise.com/how-to-permanently-enable-lte-on-android-4-2-2-nexus-4/

Instead of the complete reset he suggests, I usually edit the build.prop and apns-conf.xml files in the zip of the rom I'm using, reflash it, and I'm good to go. Remember that after you make these changes, you cannot open the *#*#4636#*#* menu, otherwise it will revert to WCDMA after reboot. If you want to switch connection types use the menu in Settings->More->Mobile Networks->Network Mode

If you want to enable LTE tethering as well, follow the instructions here:
