2g/3g switching? - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hello
I'm from Bulgaria and here we don't have 3g in all of the areas ... won't even talk about 4g.
I'm using the Sprint SPH-L720 with Sac's rom ...
The only thing I'm missing is the option to switch in 2g (GSM Only) mode.
Google gave me some hope by pointing me to Phone info app , but the version i have to use says that i cant open this kind of file , even when the file is with .apk extension.
Help ?

N9005 won't pick up 3G networks

Hi guys,
My actual phone info:
Bought with JB Stock Vodafone from Spain
Imei unlocked
Updated over OTA to kitkat
rooted via CF auto root.
Knox tripped
Phone info:
XXUENA6
XXUENA2
VFGENA4
For a week, I looked all over XDA forums, read all threads but I still can't find a solution for my n9005 problem.
Here it is: I bought one in Spain, imei unlocked it to use it Morocco. Everything worked just fine and I could use gsm network with a sim from IAM (Moroccan Provider). I then set up mobile APN to have 3G, made sure my sim is 3g enabled, but the phone refused to pick up the 3g signal. I checked the phone's mobile network settings, and found that I haf only 2 options: gsm/wcdma automatic, and wcdma only options.
Well, since Maroc Telecom(IAM) isn't offering a 4G coverage yet, I think that's normal not to have the 4g option. Still, When I use the automatic option I only get 2g signal (and can read my mails over gprs,get twitter notifications, but no internet via browser, etc..).
When I choose Wcdma only option, I simply have no network signal at all.
When searching manually for networks, I get all 3 moroccan's providers but only their 2g networks.
I was prompted for the kitkat update via OTA, updated but it didn't solve the unavailable 3g problem(and caused a few others I managed to solve).
Now, I rooted my n9005 using cf auto root, and off course tripped knox, tried to reset the phone many times, but still no way to have a 3g signal.
Thought about installing a compatible Rom, but I am a newbie, coming from the Apple world, and need some help with this.
Actually, it amuses me that I really waited until android started to ressemble to IOS to decide to switch once for all to Android
Please guys, if you have any idea to help me get the 3G signal, that would be awsome.
Thank you in advance.

Updating Custom ROM for 4G

Hi,
I have a Galaxy S4 with Omega v17 - Modem XXUEMKF and my operator has just released an update to enable 4G but of course I cannot do it since I am not on OEM android and do not wish to be either.
Currently there is no LTE/WSDMA/GSM option in my Network mode list, WSDMA/GSM only.
Can I somehow add that with an update/patch or I need to update to a latest version of OmegaROM?
Will updating the modem add LTE as an option?

Thanks.
The option is now showing up
But I am not getting a 4G signal it seems. And I am in a 4G area since I have another S4 which works just fine.
Did a speedtest and pretty sure 4-5mbps is not 4g speed.
How do you tell by the icon? It's always H or H+ in the status bar.

Ty for any responses
Does your provider offer 4G? How old is your SIM? Is the firmware suited for the country you're in?
my own same problem ( LTE option on sm-p905 not available )

My region dont have a stock rom available for this tab.
I tried to install an eu rom with no luck .
I know it is region related issue.
Is there a way to know what stock rom will be supported by my provider.
After reserching about it, I have read that that CSC is not per provider but group of provider.
So i should find a parallel rom that would work shuld I ?
Kindly help

The problem is that each CSC and firmware version has a different list of 4G activated providers that are not directly related to the region they are in.
Which means that a device can have 4G activated for 50 providers, just not the one your SIM belongs to. As such, if you insert the SIM, the 4G toggle is disabled.
Each provider has to individually pass on the fact that they have 4G to Samsung. Even then it's not activated for each CSC.
For instance, DBT (Germany) may have 4G enabled for all of Germany, as well as T-Mobile NL, Orange FR and a handful of UK networks. At the same time and on the same firmware version, 4G in the PHN rom (Netherlands) may not support any 4G network in Germany.
I've even had it happen where my Note 3 runs on DBT, and I had 4G on T-Mobile NL... Whilst none of the TNL (Branded) firmware had 4G enabled for their own network yet. (They didn't find it nearly as funny as I did when I brought that up at HQ...)
You either need to find a firmware which supports 4G for your provider, swap providers or you need to root.
If you're rooted: use a root-enabled file manager > open /data/property/persist.radio.lteon file in an editor > set it to true > save, exit and reboot.
LTE / 4G
Mine is P905M - LTE Brazil
I have no option to set only lte/4g... i just have:
LTE/WCDMA/EDGE - Auto
WCDMA/EDGE - Auto
WCDMA - ONLY
EDGE - Only
-----------------
My question is: Have a way to set: LTE - ONLY ?

If you are rooted, download and install Xposed framework. Then download and install Intelli3g (from the Xposed downloads or Play Store). Activate the module and reboot. Then enter the app and activate fast mode toggle. Then select in the fast mode menu "LTE only". That's it.

[Q] weak or no signal when selected "WCDMA ONLY" G900H india

Hi folks.
I recently bought a refurbished S5 G900H , INDIA
it came with pre-installed kitkat 4.4.2, but without using anything on the mobile i flashed a custom rom .
everything was fine until i discovered that there is a problem with the network .
whenever i try to switch network to WCDMA only i get a notification stating "NO SERVICE".
GSM mode works perfectly fine , i can make calls and use internet but with a slow speed,
the same SIM works absolutely fine with other phone with same network setting at the same location .
so i tried flashing all the stock FIRMWARE available for G900H INDIA from www.sammobile.com . but the issue is stll the same .
also tried flashing different modem available but no help .
some time i get a very weak 3G or H+ network but that too in a ground or open space but not in my home .
i have tried all the SIM from carriers available but the issue is still the same .
i can check my IMEI and baseband .
what else i can do ??
PLEASE HELP ?/:crying:
