[Q] Cannot get T-Mobile LTE enabled at all

info about my phone:
baseband: .33 right now
ROM: this one at the moment.
also tried this one, this one, and this one
also, its the new white nexus
what I've done so far:
I've tried this on the .33 baseband.
I then found these two zips (1 and 2) to help automate the process a bit, and use those to try baseband .24 and .27 with no change.
then I tried the instructions on this site
and finally, I am now on this rom I mentioned above, which is supposed to have everything done already...
I Know for a fact my area has LTE, as my roommate gets 4G on his S3 every day.
does anyone see anything I might be doing wrong?

Is your roommate using LTE with T-Mobile?
Nexus 4 only supports LTE band 4.

are you sure that your roommate has an lte enabled sgs3? the tmo lte enabled sgs3 only went on sale on june 5th.

removed

did you update the APN to fast.t-mobile.com? I can't tell in specific so ill just give you a quick run down.
On multiple devices i've done:
1) flash broadband
2) clear caches/factor reset
3) flash AOKP (or CM 10.1)/GAPPS and clear caches
4) flash franco kernel (not necessary but i prefer it) and clear caches.
5) update APNs
6) change to LTE/GSM in phone info settings.

I have done all of this. I have the T-Mobile lte APN with IPv4/IPv6. I have also tried just IPv4 or IPv6.
O have also tried creating a new APN with the correct settings
Edit: the settings in the *#*#INFO#*#* menu is LTE/GSM auto (PRL)

Disable LTE permanently?

Is there a way to disable LTE functionality permantently (software side) on the i9505?
I am in a low coverage area and with LTE enabled my battery drains much much quicker than with GSM - in Idle!
UMTS would be fine enough, I don't need the speed of LTE.
The only way I've found so far is *#*#INFO#*#* in phone mode.
But after a reboot everything's gone.
Any idea?
Thanks!

Settings /more /mobile networks /network mode
You can choose what ever you want
I just have it on WCDMA and GSM cos there's no LTE where I am.

Thanks, but I only have a checkbox "Use 2G only".
I forgot to mention I am on the latest Google Edition ROM.

Oh right.
Sorry no idea how to do it on GE, don't know if you can.
If you have exposed framework you can install Gravity Box, that gives you loads of CyanogenMod features but not sure about network modes.

[How to] Disable LTE or 4G

This is useful if you have a weak LTE signal or just don't need it always on. I found this tutorial on a different website for another galaxy phone and it works on the Note 3.
1. Turn off your phone and take out your sim card.
2. Turn on your phone with no sim card and wait a minute or two for it to turn on and settle down.
3. Go to the dialer and dial *#2263#
You should see a menu with band selections. The current setting is "Automatic".
(You have to use the menu key to select your options by using "Key Input" to type the number you want)
If you switch to "GSM All", you will be EDGE (2G).
If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Power off the phone again and put your sim card back. Upon reboot you should see your new setting in effect.

I get a service mode that says rat selection is restricted...
However *#*#4636#*#* will allow you to select whatever band you so choose. Although lte only doesn't allow voice calls

If your sim card is out when trying to access the menu it shouldn't say restricted.

Thank you inmotion! This code actually worked better for me on my Samsung Galaxy Note 3. I didn't even have to pull out my SIM card or reboot. Just dial in the code, go to Device Info and change the preferred radio network type. It changes the radio on the fly in real time, and can be seen at the top.

Since Android 4.3 and on the option to disable LTE/4G has been removed from all AT&T Android devices.

Actually it was before that. Could not do it on my note 1. Would always get RAT restricted. This was on at&t. Other networks were able to use those codes and make the switch.

1. Download the free Phone info app from the Google Play Store and install it
2. Choose the Phone Information tab and notice the "Set preferred network type" option at the bottom, marked with an arrow at the right of the drop-down menu
3. Tap on the preferred network listing currently in use, and choose the "CDMA auto (PRL)" option from the drop-down list
4. You should be now maintaining connection to only Verizon's 3G network, and whenever you need to use data, you can switch back to LTE for the duration of it
There are numerous other apps and widgets at the Play Store that claim to do the 2G/3G/4G switch, but many users on Verizon have confirmed the Phone info app to be the only method allowing them to reliably turn off the 4G LTE on their Samsung Galaxy S IIIs.

4.4 and Non-VZW carriers

These issues apply to T-Mobile users installing the current build of 4.4 (and possibly other GSM carriers but I don't have an ATT SIM to test). Motorola is aware of the issue. I read these forums pretty thoroughly and I've been answering these questions all over so I figured I'd just put them all one place. Issues as follows:
- Devices with the LTE radio active cannot send SMS
- Devices with the LTE radio active cannot send MMS (Carrier/Settings dependent)
- Devices with the LTE radio active cannot make phone calls and instantly disconnects on call attempt.
Urban Legends:
- Stock tethering does not work - I have personally tested on TMO and know it does work. Yer doin' it wrong.
Fixes
Easiest fix for now if you're on a device running 4.4 and want to... you know... be able to use your phone... is to use phone information and switch the radio mode over to GSM Only (not the auto one). This fix is a little finicky because if the phone realizes it's not running in the mode selected on your mobile networks screen it will override and turn LTE back on if you haven't selected UMTS only.
Full steps are:
Mobile network settings - Change network mode to LTE/GSM/UMTS
Mobile network settings - Select network UMTS Only
Install app linked below
Open Phone Info and select GSM Only
Phone info apk for sideload - http://www.mediafire.com/download/284l17ry2ok1yuk/Phone_info_1.3.apk
I'll update this thread as I discover more issues or as people post issues that can be replicated below.

Thank you. Finally I got the LTE turn off.
I gotta switch the mobile mode to LTE/UMTS/ gsm and select network as UMTS only. Then use phone info choose gsm only.

It was selecting GSM Only in Phone Info. Switched it to GSM auto (PRL) and I got HSPA+ back.
but Seriously dude. thanks for this info. I was tired of using my Moto G while my MAXX was just collecting Dust.

Edited the OP for a more clear fix. Thank you to vuphongkkk for pointing out the UMTS only.

I'm on T-Mobile and live in an HSPA+ refarmed area (NYC), but there are places I go on a regular basis that aren't refarmed. I set it on "WCDMA preferred" and voila, I have both 2 & 3G connectivity, with preference given to 3G.
I can't post links, but this XDA thread explains it in more detail I think: ... showthread.php?t=688492

Vodafone confirmed for anyone wondering.
H+ for UMTS only,
Edge for global.
No Sim adjusting at all

Just popped a sim in today. Getting LTE but really hating the call fail bug. Gotta place the call twice repeatedly to get it through
Maxx'd out Kit Kat

Update: Having major glitches when running LTE, pretty deal breaking for a full switch to tmo right now. Eagerly awaiting the new OTA to see if it fixes it. Seems to have major issues on the HSPA/LTE handoff. How did it function prior to 4.4?
Maxx'd out Kit Kat

On 4.2.2 was working fine, the phone just switch from LTE to 3g itself when you need to make phone call. But I had problem on 4.2.2 that if I connect to WiFi then it'll take awhile to get the LTE back. Normally an hour after out of WiFi range

You can uninstall it if you want. It's extremely small though so no reason to do so unless you just don't want to see the icon. Uninstalling will NOT reset your settings.

Thanks! I messed myself all up though.
In android mobile network settings should I have network mode as global, LTE/CDMA or LTE/gsm/umts?
If its LTE/gsm/umts do I still use gsm only under select network?
And if I leave phone info installed do I have to change anything on there for LTE to work? Phone info seems to change the network selection in the app on its own so I just stopped messing with it. Thanks and sorry to be a pain

4.2.2 rarely get LTE data. Choose network mode as LTE/gsm/UMTS . select network as automatic. Don't use the phone info. If you already use the phone info app in this thread then use it again to switch back to LTE/gsm.. Or the option that has evething.
Remember to add APN fast.t-mobile.com
But as I mentioned, 4.2.2 has some problem with the radio , so it rarely pick up LTE

It uses the same CPU as the N910C, but I doubt the Modem is the same, meaning it may never do LTE.
I could be wrong, and for your sake I hope I am.

Hi i have done that code in app info and there it show the lte band and in the settings it show the option to choose lte/cdma/gsm and it is tickable but when it is choosen when i am in an area of 4g reception i lose signal. I think there should be something to be enabled. Or maybe there is away to enable different lte band because band 5 and 7 are not enabled

When i reach this page i dont have the option to change band or to save the configuration. I will upload my page later on
