First of all let me apologize to all those who I did not believe when they said they got LTE on their H version of the Note 4.
What I did was download the C version for Croatia (tele2) from www.sammobile.com.
I then removed the modem, hidden, and, sboot.bin from the firmware and re-packaged it using TAR_MD5_PACKAGER.
In recovery I factory reset the device, powered off and installed my packaged MD5 of Croatia (tele2) using Odin.
Then I flashed a C version modem even though it failed.
The problem is after a while I loose LTE. It will switch from LTE to 3G then to HSPA+.
I have changed my build prop to mimic an AT&T phone as well as the CSC others.xml file to mimic an AT&T phone and used AT&T's NxtGen APN but eventually I will lose LTE.
I can go into settings then More networks then Mobile networks then chose Network mode and switch from LTE/WCDMA/GSM to WCDMA/GSM and then back to LTE/WCDMA/GSM to get LTE working again but eventually I lose LTE and am back to H+.
I have done speed tests and I do get comparable speeds that I normally get on my AT&T LTE devices so I am sure that I am really getting LTE. Has anyone figured out a way to keep LTE without having to restart or go through the settings to get it back?
By the way I am not sure that it matters what firmware of the C version you use as long as you factory reset.
Edit: Added another screenshot, it seems that it only kicks me off of LTE when the signal is too weak and the phone has switched back to LTE at times on it's own.
Sounds like you need to either reinstall the original stock firmware for your Note 4 or install another custom ROM for it. As it seems the LTE drivers for the ROM that you are currently using aren't working very well.
Or your Note 4 may have developed a fault and needs to be repaired/replaced.
Also since you have a N910H, which is a 3G model of the Note 4 you should not have LTE/4G capabilities.

Hi, I have a Samsung Galaxy S3 I9305 LTE which is originally from Three UK, but I have tried a couple of stock roms, one of which was unbranded from Germany and another one which is the EE UK one, all of these on Android 4.3.
Now my phone is able to pick up a 2G or 3G signal (be it 3G/H/H+ whatever) but it will not pick up a 4G LTE signal even though the same EE4G sim card I have will work perfectly fine with signal in my Samsung Galaxy Tab 3 LTE?
What am i doing wrong or is there any way to enable the phone to actually use 4G? (I have made sure the network mode is set to include 4G as "Auto Mode")
~ Many thanks for anyone who is able to offer me the time to help ~
Maybe try another modem. I am from Germany and had to change modem from xxuemkc modem to xxbme1 modem, because lte didn't work on first modem, either.
Try one of these

Hi, I have managed to solve my own question but thank you ever so much for taking the time to help me
It turns out that I had to downgrade my phone to 4.1.2 through Mobile Odin and then enter Service Mode and from the Debug Menu there is an somewhere within the UMTS, DRX Control option to enable LTE DRX 0X1 1X0 or something on those lines, so I enabled it and voila i now get 4G!

Same issue can you help me
I have an unlocked Galaxy S4 active i9295 and I cannot get the 4G or the LTE working since I do not have even the option I only have WCDMA/GSM I travel around the world with this phone and now I am in Ireland on 3 and still I am getting H+ showing and not LTE or 4G. Is there a way to activate 4G or is there any special 4G sims ?
I would check your APN settings, seeing how you are unlocked, the proper APN may not be installed to match your Sim, check with your carrier, to make sure they are 4G and LTE capable and get their settings.

Try ShowServiceMode. It should help to unlock LTE band. It worked for me here in Poland, because local career's LTE was locked by my Russian firmware. But using this program I can only switch between phone calls (GSM/3G) and LTE, they cannot work simultaneously.
Thank you guys. One major thing is that why I can even see the option in the settings? If anyone else has some information please help out.
Thanks
I've had this problem across multiple roms, so I believe it's could be something with the radio or the kernel(mabye?). My phone will only transfer data on LTE, when I am in an area that does not have LTE coverage, my phone does not automatically downstep to 3g. HOWEVER, if i go into cellular settings, and manually set 3g CDMA, it will connect to 3g. All speeds seem normal LTE 15-30mbps 3g 1-3mbps. I have no idea why it doesnt downstep to 3g on it's own. It's like it's stuck on LTE only. ANy idea how to rectify this?

try to update profile and prl, i know it's basic, but it solves most problems very often. if not make sure your firmware is up to date, not just the ROM, as the radio will need to have been updated and TWRP/CWM wont do that.

I've gone ahead and done that. Updated PRL/Profile. I have updated the firmware to the most current 5.0.1 firmware. Same thing. When i lose LTE, it does not step down to 3g. I just lose data. If i go into cellular options and I manually set 3g it will join 3g, but then i have to remember to set it back to LTE later. Any idea why the phone isnt doing this on it's own? Is there an update to the HTC radio that could fix this? Is the radio even responsible for these actions?

if you updated the firmware correctly that includes the radio... call sprint, since lte is handled by the sim card and 3g by the phone internals maybe the internal imei isn't set up correctly
Sent from my HTC One_M8 using XDA Free mobile app
Greetings folks. I own a Nexus 6 XT1103 Unlocked. I'm on MetroPCS currently (piggybacks off T-Mobile LTE).
On Android 6.0.1 ROMs the device connects to LTE networks with no issue whatsoever. The real issue arises when I flash an Android 7.x ROM. The device connects to 3G (UMTS/HSDPA) and remains there even though the network setting is on LTE.
The phone momentarily connects to LTE when I reset the radio from LTE Discovery app and then reverts to 3G (the LTE signal detected just drops off to N/A). Also when the device is momentarily connected to LTE, the carrier label changes to 'No Service' even though network is available and LTE data works for those few moments. After those few moments it's back to UMTS and the carrier label returns to 'MetroPCS'
I've tried the following things to fix this (all in vain)
1. Flashed different radios (05.32, 05.34, 05.42) and bootloaders
2. Flash Android N stock image and then flash custom 7.x ROM
3. Go to the *#*#4636#*#* menu and set LTE only.
4. Resetting APN to default and manually adding APNs (both MetroPCS and T-Mobile)
I know the LTE network in the area is fine otherwise and anyway the moment I'm back on MM the issue the device connects to LTE properly (with a valid MetroPCS carrier label). This issue occurs on any Android 7.x ROM but it didn't happen as often in the Dev Preview, if I remember right.
I request all of you folks to help out if you've seen something like this or have any solutions. Cheers.
PS: Google Connectivity Services installed/uninstalled/disabled doesn't fix it
Have you tried a network settings reset? This worked for me when I lost LTE connectivity.
Settings>Backup & reset>Network settings reset.
Make sure you select network settings reset and not factory reset. They're right next to each other, so if your finger slips and you select the wrong one you'll be very unhappy.
Fixed it!! Flashing the 05.39 radio on fastboot before flashing the ROM seems to do it. Now LTE works with the proper carrier label too. I'd forgotten about the 05.39 radio as it was the one bundled with the N Dev Previews.
Cheers!
I am using the dual sim Exynos version of Note 9 and want to be able to force 4g LTE on either of the two sims as needed.
Can someone please advise how to do this on an unrooted phone? Thanks
Anyone?
I also found no solution. I think it's possible without root but no one is updating the Phone Information Apps. We need to get access at phone information 2 and not only on 1
Mine are both 4G / LTE. Inever need to switch the Sims around. Whichever I choose for days gets LTE. this is different from what I had in the Note 8. I was pleasantly surprised. Therefore it may be a settings issue for you. I have the Note 960F/D
you may try quickshortcutmaker app on exynis version and follow instructions in video
https://youtu.be/AdGAB4qRvYA
I feel like the Tasker App could handle this easily.
I dont understand the actual need.
Simply changing preferred network mode from LTE to 3G shall do to stop LTE on any sim.
I use LTE on both sims for calls
I use LTE for data on specific sim by making it as preferred sim for data.
Settings -- Networks -- Sim card manager shall help in these settings.
I am on exynos N960F Indian firmware.

You don't understand the actual need ??
So i will tell you
On my work i am located in a big Hall underground. The Provider i need down there is only coming in with -110 dB and less which is one LTE Bar. If i leave Automatic Mode it switches always in 2g Mode because of much higher Signal. So to get a nice experience and have LTE always available there is no other solution. The same kind of problem is on my other LTE Sim when on different Locations during the Day ! So i have no time to always switch sim cards so that sim2 is forcing lte !
And off course no one else knows this and so i benefit of this extremely fast connection where all others are crying because of no 4g connection

OK understood.
Did not you get one UI already which has option of LTE only selection too for network mode.
Negative. Here the German Rom (dbt csc unbranded)
Has never got LTE Only mode in the menu. This is also for all European Roms. I have had this only when using Root and Custom Roms.
Because i use many banking and streaming apps it's not possible to root this time. Even with Magisk Hide they will not work.
If i could i would have rooted long time ago. This is getting me Crazy really

Sorry but are you reading my Post?
I am talking LTE Only on Sim Slot 2 of any Samsung Phone out today. All the LTE Only Apps or the Phone Info Menu where they lead you is only working on Sim Slot 1.
I am sure there is a dial code like the one it gets you to the Phone1 Information Screen where you can change the bands. But only for Sim 2 (Phone info 2) on Samsung.
So again LTE Only on sim Slot 2 on Samsung Duos Versions is not Possible @ the moment without Root!
If there is any Dev out there you would be the first One to create an app where Phone INFO 2 is possible to change! Or just find the right hidden code for that i know it's there like the Phone Information 1
Hi,
There's an option to force the selected APN to LTE only but I don't know if it will behave like you want to.
What's great is that it's per SIM so you can try any combinaisons.
Deselect "undefined" and select only the "LTE" one (screenshots).
I expect that if it find any other bands getting a better signal than LTE, it will just let the phone loss the signal and not trying to catch the LTE one, but you can try.

Hey thanks for that. I really was in hope this could work but that would have bean to easy. Unfortunately it's not changing bands after deselecting undefined and than choose some network mode it remains to the same band but it looses the mobile data symbol (but still remains in same band).

This code and all Codes are not working on European Samsung Devices with Android 9 .
I Even Rooted my Galaxy Note 9 and all the hidden codes are Not working ! Even Samsung Phone Info App or other Apps are not working with Latest Android 9.
Only way is Root and Custom Rom like Alex Dev Rom where the CSC is Modified. There it was possible to change both Sim to LTE Only ! But as told before with Root
i loose to many services which are detected even with Magisk . So my next Phone will not be Samsung anymore because of that.
