How to force LTE only on Sprint Galaxy Nexus? [Without Root]

Is there a way to do this and if not is there a way to do by rooting the phone? What is the best and simplest way to root the phone if need be. Like a stock root by just rooting it without flashing new ROMS.
I have decent 4G LTE coverage like 2 or 3 bars but my 3G coverage is like 3 to 4 bars so it keeps switching over to 3G. When I am in the right spot like upstairs rather than downstairs the 4G LTE is blazing fast. If I had a program to keep it on 4G LTE downstairs that would be great.

Dialer>*#*#4636#*#*> phone information> scroll down and choose lte only from the menu
Hope it helps

That won't stick.
And you can't force LTE only even with root.
LTE is data only, how are you going to receive calls and texts?

Dialer>*#*#4636#*#*> You have to have MSL number which I can't get on the Galaxy Nexus Sprint Version. And also I heard that it does not give you an LTE only option just the same one in the system [LTE / GSM].
Also I don't care whether I can make or receive calls. When I just want to use the phone for DATA at the moment I use Foxfi so I can just use it as a wifi hot spot. When I am done I can put it back on to 3G.
Anyone know how to get the MSL number for Sprint Galaxy Nexus?
Also you are telling me with root or no root there is no way to force the phone to stay on 4G LTE? I find that hard to believe and if it is that is sad.

It is not possible to do LTE only on this device.

Why is that? Can anyone create an APP for it or is it hardware?

Is there no way to build a ROM/kernel from AOSP that has the CDMA radio disabled? does the LTE radio require the CDMA radio to be transmitting?

Exactly, I mean if the radio can be on 4G and not 3G why can it not stay on 4G? Is it still on 3G when it shows its on 4G like on both of them on at the same time? And if that is the case can you force the weaker 4g as primary and leave 3G on in the background?

Anything at all here? Will some of the apps on the market work for the Nexus? What if I get msl code and use 4G only in that? Has anyone tested that?

It uses 3G and 4G concurrently, if not how are you going to receive calls and texts?
Like I already said, changing it to LTE only in the *#*#4636#*#* menu won't stick, regardless of whether you are rooted or not.

part 2 still stands.

Yes I do not care about voice calls. If I want to download a movie or something I do not have to have calls during that time. So has anyone found any new information or app that will perform this function to Force 4G on the Galaxy Nexus? Again I do not care about Voice Calls.
Sent from my Galaxy Nexus using XDA Premium App

All the Mifi hotspots can be set to do LTE only. This should definitely be possible especially since support for voice through data is right around corner.

Okay I rooted my phone, and got MSL code, but now when I go through all the settings I still do not have LTE only setting just hybrid as my last option. I have been reading some forums and some people with Sprint phones have LTE only option. Is this true? Do I need a paticular ROM? Anyone figure this out or have any idea?
Best,

This works on my Galaxy Victory for Virgin Mobile.. it does mean you can't recieve calls but I use it anyway..
Download an app in play store called "Show Service Mode" - costs a little $
Open the app
Select the third box to create a shortcut
Go back to the main screen and click the new shortcut
Select LTE band preference
Then select LTE ALL
DONE!!!
To switch back to normal open the same shortcut and choose automatic

If you mean being able to use internet during a call, it depends on your carrier and the wireless technology they use.
If your carrier uses cdma technology (e.g. Verizon), then you cant, as cdma does not support voice and packet service simultaneously.
If wcdma is used, then you can used both voice and packet service at the same time.

That's weird, because I'm on Verizon and have used Chrome several times during a phone call.

Is that you mean this is the network operator problem, not Note 2 (phone) problem?
But I tried to use the same network operator (in my country called DIGI, my current phone line) with IPhone, it work fine!!
But, when I put the same SIM card into Note 2, it does not 'always' work!! I mean sometime it work, most of the time it does not work!!

Your area may have bad 3g connection (3g,H,H+) and signal will drop to only GSM (GPRS/EDGE). In GSM mode you cannot make calls and use data connection at the same time.
Try changing your network connection to only WCDMA and retest.

Data issue...

Ok SO I could not find a proper thread for this since there are SO many threads. The issue I'm having is I got a Samsung galaxy S III that was unlocked, and after I put my ATT sim into it I could recieve texts and calls but I could not recieve data. So I rooted it and applied clockwork with all my mods and figured I could find some setting that would fix it... well I was wrong. I tried global, GSM and LTE settings none of which would give me data. If there is anything anyone can do to help I would be more than appreciative.

While I agree that you should always call at&t so they can register a device to your account, this will not help his current data issue

Ok so this is a verizon Galaxy S3. It is rooted running 4.1.2 JB, Kernal 3.0.31. After I got the phone I did go to an ATT store to register a micro sim because i didn't have one at the time. So the imei is registered to my sim card perfectly. I can get calls and texts without any issue but no data. How do I figure out what the apn settings are and if I have the right configuration?

You do realize you're trying to use a cdma phone (verizon) on a gsm network (at&t), right? Different radios. Different technology. Won't work

Well it was unlocked at the phone has a gsm option so if it wasn't compatable I don't see why they would have the option there to actually use a gsm network.

You need to read more.
this phone only supports GSM with EDGE data.* This essentially means that you'll get 2G data speeds (unless you have a WiFi connection) because it doesn't support UMTS/HSPA+ which is required for international and U.S. 3G data. the 4G LTE frequency supported by this phone is only used in the U.S.* For those who don't know UMTS/HSPA+ is the 3G technology used by GSM carriers internationally (and used by AT&T and T-Mobile in the U.S.) which is different from the CDMA/EV-DO 3G technology used by Verizon and Sprint.*
This phone IS unlocked, that part is correct. But only for gsm carriers

So its preventing me from recieving ANY form of data possible?? It is a Verizon phone and I have ATT so you mean it doesn't support GSM then right?

You're in an at&t s3 forum with a verizon s3 that has zero data. If you really want to pursue this issue, you should start looking around in the Verizon S3 forums

If I'm not mistaken, some Verizon devices will not work on US gsm networks even if unlocked, only foreign gsm networks.

If you are going to stick with AT&T, that is the way to go if you want to have data. No worries. Stupidity is only if you didn't learn anything. You had ignorance of the situation and now your don't. Do some research on any phone before you buy next time (especially if branded from another carrier). This can save you a lot of headaches as you have just learned. Just remember some basics from this forum. Good luck.

Wifi tether for tmobile galaxy s4?

Hi guys! I just got my galaxy s4 yesterday. I rooted it, and I got wifi tether on the device. It didn't work, and I was wondering if it was the app's problem for not having support for gs4, or tmobioe blocking any tethering action for people with no hotspot plan, or that I just have the settings wrong. Can anyone help me? Thank you!

Changing the APN (Access Point Name) won't make tethering "work". There are strings in the framework that need to be modified for it to work without getting cut off. Believe me I know, I had the fix in my ROM for the Note 2. The guy above is posting from outside the USA/T-Mobile with an Xperia lol.

Ohhh okay. So no way until someone makes a rom that can breai away from tmobile stuff?

I had used APN backup & restore on both S3 and Note 2. Hopefully, its dev will be able to setup an APN that will work with the S$.
Note - it will only work on 3/4 G, so you would loose LTE after restoring modified tethering APN, so you would have to backup the LTE APN and then restore it when you want to go back to using LTE.

There is no unlimited mobile hotspot yet, until then, you can call T-Mobile and they have free tethering for up to 500Mb until someone can unlock it for us.

Same problem without rooting
Guys,
I just bought the At&t version of S4, got an unlock code for Sim and put in the nano T-mobile sim, all was good, got 4G internet from T-mobile and made calls. Tried to turn on my hotspot feature from the phone itself because T-mobile hotspot is free up to a limit.
Was not able to turn it on, it kept going to the off position with the error "MOBILE DATA IS NOT AVAILABLE OR INVALID SIM".
Of course I had my wifi connection off and had 4G connection from T-mobile. Got off with t-mobile customer service and got their APN settings, was nothing to change.
Yet my own samsung hotspot feature doesn't turn on. I think samsung has turned off this feature in US versions of S4, so even if you root, you wouldn't be able to get hotspot on.
At least that is my two sense on this matter. IF any body knows how to rectify this issue, please help.

It's saying invalid, because the strings in the framework point to an AT&T APN. Once again.....the strings will need to be changed for this to work.
I know that this method works with any plan, because I had the android preferred (5gb no tethering for $20) and now have the truly unlimited; and the method I speak of works on both.

Call prob after official 4.3 update

My wife has this phone and I have the s3. After doin TT the update to 4.3, we both have experienced the same issue. When I am on 4g and she is on LTE, we cannot make calls to someone on WiFi calling. We can receive them just not make them. All other calls work. When on 2g or edge it works. I finally found a fix for mine, since my s3is rooted, I reflashed the modem only and mine is fixed. My wife won't let me root hers, the note 2. With that being said, what are my options, because I think that would work for hers, but she won't let me root.

I have the same issue with my stock 4.3 Note 2... not sure what happen during the OTA but im led to assume that with all the newer LTE phones, note 2 users arent the only phones accessing those bands, and something was shifted that creates more instability with wifi calling. I say more instability, as even when I was on 4.1.1/4.1.2 there would be times when friends/family would call/message me when I was connected to certain wifi's (at my girlfriends/etc) and the call would never come through, the messages would receive until I disconneced from the wifi. Even when leaving a voicemail, it was hit or miss for me to get those until I disconnected from wifi.
Not sure if it is a compatibility issue from being connected to edge vs lte vs etc (like you have narrowed down) as it may be a wifi router issue, or just initial bugs with wifi calling in general, considering wifi calling is still (in my mind) in its infancy stage

I wouldn't necessarily say WiFi calling is in its infancy. I've been with T-Mobile since before the first android. We had Wi-Fi calling with the 2nd android phone T-Mobile had, the cliq 1. Every phone we have had has had Wi-Fi calling since. The first hiccup we ever had was with the HTC one s. With the note 2 we haven't had a problem until the update. Being an IT tech, I couldn't help but do my own ts, since it was happening to my s3 as well. What we found was it only happens if she makes a call on 4g or LTE going to a phone that has Wi-Fi calling turned on. If that person turns it off and goes to where they actually has signal, the call goes thru fine. My s3 was doing the same, but it is rooted.
We have put several calls into T-Mobile IT dept. That has stumped them badly. They have no idea why this is happening.
On my phone, I finally had the bright idea to reflash just the modem. It worked. No more issues on mine.
I can't root hers(she won't let me), and I know that will fix it by flashing the modem only.
So, sorry for long post, but that is where I'm at. I'm stumped, unless maybe just using Odin to flash the update all over again (like that will happen, she don't like it when I play with her phone).
