Galaxy S5 LTE will not connect. This Fix worked for me.

I followed the instructions like another thread comment said to do but for some reason I couldn't get it to work still but after playing around I was able to get it working.
---- Instructions for enabling: (thanks eyecon82) ----
1. dial ##3282#
2. then click edit (need MSL code) (I used SPCUtility.apk as nothing else worked on my S5)
3. then click LTE
4. It will show LTE ( also known as Band 25), Band 3, Band 26, Band 41 ( I unchecked marked all of these but the LTE option leave that check marked to on)
5. Disable all bands leave LTE check mark to say on.
6. Go to the main directory by hitting back key and choose More at the bottom
7. Choose HDR/1X Selection and choose LTE only Mode. Click OK to save
8. You can either reboot or I just turn on airplane mode and turn it back off to reset the connection.
9. LTE should be working like mine did. But you will not get phone calls until you turn back on the HDR/1X Selection to LTE + CDMA +EVDO Mode but you will get text messages fine.
The items that are underlined in Red are the stuff i added.
---- To tell what Band on: ----
1. ##debug#
2. enter passcode 777468
3. go to LTE engineering menu
I hope this helps because all the other stuff I read would not work for my Galaxy S5 I just bought.
Thanks

One more thing
I read on here http://s4gru.com/index.php?/blog/1/...-due-to-circuit-switched-fallback-technology/
that this problem should be fixed soon but if you need LTE now here it is.

Thanks for the info. However, I think its crazy to want to set it up for LTE when you cannot receive phone calls especially since this is you know, is a phone. Calling Sprint and talking about this situation is useless. They all say nothing is wrong and its the device. I'm really pissed off about this but I enjoy the phone. This will probably be the last Sprint phone I will get.

I use it at night or in places that I need fast internet and when I know I dont need a phone for a bit which is why I have voicemail I just switch over to LTE for a bit and then back...but yes it sucks for now until they upgrade the tower over here with the feature needed to use LTE spark devices.
Im loyal to sprint but its becoming more and more hard to be loyal.

Probably just your area, not the phone.
Your area may have LTE but if it doesn't have the circuit fall back enabled yet (tri-band phones) can't drop the data to allow a call and thus they force you to remain on 3G only.
Once your area has everything done it should get better.
I have similar situation that KILLS my battery at home but in every other part of town it all works great :/

Found out from reading the Sprint forums (https://community.sprint.com/baw/thread/157300?start=0&tstart=0), that this is likely not caused by the circuit fallback, but incomplete rollouts of Spark technology. Disabling the new Spark bands has helped me keep a stable LTE connection. Once the Spark rollout is complete in my area, and Band 26 can support both Voice and Data, I'll re-enable it the new spark bands.

Which bands did you disable? Also, are you able to get voice calls when you LTE?
Im a bit frustrated be the place I spend most of my time (where I used to get LTE fine with my S3) I no longer get LTE and its super slow 3g. Calling sprint didn't help, they just say to wait until cell tower updates are finished in the next 6 months.
If I disable the Spart bands, will I be able to keep LTE and voice? Thanks

I disabled bands 26 and 41. This forces the phone to use the default sprint LTE band. It receives voice calls just fine.

But if you enabled the spark LTE bands like the default settings, will you LTE work or does it fall back to 3g? Thanks

LTE works fine because it defaults to the standard LTE band.

Then is there any benefit in disabling the other bands?

Read the sprint link. Incomplete rollout of spark, in particular on band 26 can cause the issue of not being able to switch between 4G and 3G and back.

Is there a way to enable voLTE through hidden menu?

I have SM-N910U model of the note 4 and would like to know how I can enable voLTE. I know my phone supports it, but I can't find it anywhere in the settings nor is it active. My carrier has voLTE, but the phone data drops to 2g when I make calls. I would like to know a way to enable voLTE, so the data stays at 4g while on the call.

Or is there a way to add volte to international roms seems like it is only for carrier branded phones

I have the same problem with Galaxy Alpha on the Metro/ Tmobile Network.
LTE drops to 3 G on calls and often kills Data
during and even a minute or so after the call.
Not good for multitasking- this is a Factory Unlocked Alpha NOT a native Tmo / Metro phone .
The 4G LTE Tmo/ Metro Phones always have simultaneous voice and data so you can be on Web while on a call.
I think some have VoLTE and some have dual band simultaneously in the firmware specifically for Tmo.

Yes you are correct. VoLTE service can be enabled only with layer 1 modified kernel/drivers. The hardware itself definitely supports it, but firmware doesn't. Main reason the Samsung decided to disable this feature is because not all carriers in the world use voLTE service and enabling the service on the user end may trigger unstable and disconnection during call. I have contacted Samsung by Twitter and have yet to receive a response if they are going to enable this feature or not. Will let you know if I hear anything back from them!

Thanks. I wonder if some Dev here can do it for $ 100 .
Really like the size, speed and great Audio quality of Alpha and was going to get the larger Battery but I often can not get back on Internet for a few minutes after a call-
while the Phone says 3G (?) then it goes back to LTE and back to Internet...frustrating .
Am used to Metro PCS VoLTE since 2012 and had not considered this problem with a Factory Unlocked non Carrier Device.
No one reminded me there would be no VoLTE and sometimes no voice and Data simultaneously...
So DEVs figure it out for me and I will have a Tech here do the Install/ Download.
Alternative will be a too big branded S6 either Tmo or Metro which will have a better Camera, even slightly better than Note 4 but I love the small form factor of Alpha- this is Alpha 850 M.
Don't think Samsung will help although there is rumored to be VoLTE with Lollipop so there's a possibility.
Will Lollipop VoLTE perform like a Branded Metro PCS with LTE remaining on Display during calls and simultaneous Internet ?
Anyone have a Beta Lollipop for Alpha that achieves this ?
Thanks.

Meizu MX5 no 4G network capabilities

Hello,
I have been using my Meizu MX5 for about two months now without the 4G network working. I have recently updated to the latest firmware and I am currently running Flyme OS 4.5.2.7A and that has not solved any issues either.
I have checked that the phone settings are configured properly.
Network Mode is set to "4G First".
The phone is pending between, H-, H and H+ connection (3G I believe?)
I have checked with my provider and these are the following frequencies which should be providing 4G in my country (Sweden) for the provider:
800Mhz, 900MHz, 1800MHz, 2600MHz
Other providers have the same frequencies as well.
I have also gotten two new SIM-Cards during this period of time without it solving any issues. I have tried the SIM cards in some other phones and they get 4G connection without any issues.
I have been in contact with Meizu customer support in China and after some random troubleshooting of factory resetting and reinstalling the same firmware on the phone without solving anything.
They have also provided me information regarding the different bands/frequencies which the phone operates on:
GSM/GPRS/EDGE (900/1800/1900MHz)
WCDMA/HSPA+: Band 1/2/8 (900/2100MHz)
FDD LTE: Band 1/3 (1800/2100MHz)
TD-SCDMA: Band 34/39 (no freqency specified)
TD-LTE: Band 38/39/40/41 (no frequency specified)
I am not 100% sure on how this works but according to the information I am given, the phone and my provider share at least one frequency for the 4G network and therefore I do not understand why it is not working.
I am sure that it is software related and thus I won't send my phone back to China (4-8 weeks delivery time and all expenses has to be paid by me) for them to troubleshoot.
Anyone here who has knowledge which could give me an answer?
Kind regards,
Martin

Hi mate.
I had this problem but upgraded to new firmware late last night and it came on. Thankfully!
Give it a try

Hi,
I have checked the upgrade app on the phone and it says I have the latest firmware.
Which firmware version are you running?
Kind regards,
Martin

Maybe it is an APN related problem. Look if you have the same data as in the other phones that 4G works

Hi iicc,
Thank you for the reply.
I have checked the APN settings about four-five times and I can't find any inconsistencies. I have even crosschecked it with a support technician from my provider.
The only things I can think of is either my anntenna being gimped, that the firmware is not properly developed or that somehow there's trash in my system and that my phone maybe needs a complete wipe and reinstallation.
After the upgrade to firmware 4.5.2.7A the phone does not even hint on trying to connect to 4G. Pre-upgrade it atleast connected to 4G for about 5 seconds and then went down to 3G.
Kind regards,
Martin

Let me try to come up with something that might be your problem. If you are using 3 as your mobile provider then they use FDD-LTE band 7 & 20 none of which are supported by the MX5 and 3 are also using TDD-LTE band 38 which is supported by the MX5, but might not be available in your area.
If you are on Net4Mobility then they use FDD-LTE 3,7,8 & 20 of which only 3 is supported, so it could that in your area there is no coverage with band 3.
If you are on Telia, the story is pretty much the same as Net4Mobility as they use FDD-LTE 3,7 & 20.
In order to get more from your phone. You can open up google and search for 'meizifan eu' and go to the website. They have a pretty good description of how you install the international version of FlyMe on your MX5, the international version is called 4.5.2.7i. I believe it activates some other FDD-LTE and TDD-LTE bands.

1800Mhz band is a short range, higher bandwidth frequency which usually is less common and given that it has a short range it most likely isn't available in your area.

Thank you for the reply nasty_suicide!
I am using Comviq Tele2 as provider, which should use the Telia net.
This is what I believe as well, but I really thought there was no way to flash the international version onto the phone and was about to abandon ship by buying a new phone yet again.
I will try to install the International version as soon as I have time to follow through the steps. I have found the guide on Meizufans.
Once I have installed the international version I'll let everyone know the outcome.
Kind regards,
Martin

Hi Hawdes,
I've exactly the same problem as you do, please post back once you instal I version. I was planning to do so but since I already have everything installed I didn't want to go through trouble for nothing.

What were the results of this? Is it true that firmware can affect the signal received?

upgraded to the latest firmware yet?

Does T-Mobile Band 12 Work If VoLTE is Turned Off?

Saw that MM users are reporting some issues with T-Mobile voice calls when Enhanced 4G LTE Mode (VoLTE) is enabled. A suggested workaround is simply to disable VoLTE.
T-Mobile requires VoLTE support for Band 12 access. If phone has VoLTE disabled, does this then disable Band 12 access on T-Mobile?
I'm watching the current MM public beta testing to see if I want to take the plunge. The main reason I would update to MM is to get Band 12 on T-Mobile, but if VoLTE has to be disabled because of voice call issues and this disables Band 12 I'm going to stick with 5.1.1 for now.
Appreciate any info.

It doesn't disable band 12 from what I can see.

What public beta?

Band 12 doesnt work on mine at all after upgrading..

Nexus 6p - is Band 12 working for me? how to check?

I'm not sure if I'm getting band 12 on my new Nexus 6p - T Mobile. Is there a way to check this? I am running PureNexus. Not sure if there is a better modem I can install.

all recent radios support band 12
if there is band 12 on your area, LTE Discovery app will show it to you.
if you are on band 2 or 4, u can use the app's data connection reset, it will likely connect to 12 and if its weak, it may move on to the next strongest band
