[Q] S4 Problem with network WCDMA (3g)

Hi all, I have a problem with 3g.
I bought s4 i9505 and it was on 4.2, I had problem with slow internet, so I called operator and they told me to turn on WCDMA only in settings..
When i turn WCDMA only on, it loose my network (emergency calls only), and i have no network at all.. when i put wcdma/gsm automaticly it has normal network..
So i thought its problem in firmware, so today i fleshed 4.4.2 with odin.
Now i have same problem, no network with wcdma only..
I serached internet and i tried several programs for 3g, but nothing worked.. any solution ? thx

did you try another simcard?

Some problems can appears:
1. Type *#1234# and paste here what appears. Continue with the step 2 if you have wrong CSC.
2. Wrong CSC. Solution: Install Kies 3 for know ur CSC (pic 1). Go to Sammobile.com and download the correct firmware 4.4.2 (correct region) for your device.
3. Flash again this firmware and let the process finish till the final. Dial again *#1234# and verify if all is correct like the firmware you downloaded and installed before. Flash again same firmware if not.

Seems correct but its better that you install Kies 3. Add here one screenshot of Kies 3 for avoid problems :good: and for verify ur CSC.

this is what it writes

Might be a corrupted EFS folder.
I have had the same problem for 3 weeks now. I've tried searching for a solution here and in other online sites to no avail. I personally tried flashing a new stock rom, flashed some odd number of modems, tried factory resetting etc. Nothing worked. I'm afraid it might be due to corrupted EFS folder which I still don't know how to repair.

[Q] Samsung Galaxy s 4 issue with mobile data

recently my samsung galaxy s 4 on the carrier US Cellular and running the stock android version 4.4.2 has stopped communicating with 4g lte. It will show that there is a 4 g lte connection but will not connect to facebook messanger or do anything internet related. It will occasionally drop to 3g and work fine or drop connection all together.
In my attempts and large amount of research to fix this problem i have done the following:
1. Turned on and off airplane mode
2 restarted the phone
3. Replaced SIM card with a new one
4. Factory reset my phone
5. Erased application cache in the recovery mode
6. I have also tried to change the network mode and yes mobile data is turned on.
Please help. Us cellular is just telling me to buy a new phone that i cant afford because they dont know whats wrong and samsung is saying the same thing. ***Also it is not a rooted phone*****

Dial *#1234# and tell me what appears with details pls.

I attempted to type that in and nothing happens. I have tried other codes as well and same result.

Install Phone Info from the Play Store and run it. Tell us the AP, CP, and CSC of the phone.

The original samsung firmware doesn't seem to recognize some of those USSD codes. That's why nothing happens.

@GDReaper: *#1234# is one of the codes that does work in the Samsung dialer. US Cellular has blocked access to that information, which is why it's not working for him.

desperately in need of help s4 i337m no sound can't call etc

Hi everyone I've been lurking around the forums the past week trying to find a fix to my problem and I just find anything that will fix it. I'm hoping one of you that has a bit more experience with this can help me.
OK so here's my problem
My Samsung galaxy s4 i337m was rooted but I wanted to unroot to update cause I'm new to it and never used my root for anything
I looked around and downloaded a stock ROM and flashed it in with oden and I had no WiFi no sound couldn't make calls no videos so I tried flashing another custom ROM and it let's me use data and text but no calls no video no sound I usually only get 2-3 hours of down time here to look for a fix and I have been all this week but can't seem to work the problem out
Does anyone know how to fix this so I can call my kids again I'm not gonna be homeor anywhere close to a place to get a new phone for another month
And to sweeten the deal I'll send 25$ PayPal to the person that can get this fixed for me
Thanks for your time

Thanks for the reply I'll try it when I get off of work
So let me get this right I DL it flash it check it if its good with sound and WiFi I flash it again?
What about if it isn't good with WiFi or sound any thing else I can try
Also when I dial that number now it pops up connection problem or invalid mmi if that makes a difference

1. It's the correct firmware for your device and the latest. Yes. Problem of sound/wifi are related to wrong baseband normally. Reflashing it 2 times solve the problem.
2. We will try other options.
3. You have to install STOCK ROM for dial *#1234# first.

not registered on network

Hello,a few weeks ago I bought s7 edge which was rooted(bought not new phone) ,I wanted to instal stock fw,I mean to delete that root.So I tried to factory reset,it didnt helped,and the phone started to lag,so I instaled 7.0 stock fw,everything works smooth now except that I cant call,or send text messages,it says not registered on network,on 6.0 everything was fine,so any ideas how can I fix this issue? Tried instaling different fw's,even tried old 6.0.1 still got the same problem.I checked my imei its not blocked,everything is fine

Download the corresponding firmware for your supplier, or find out the APN details for your carrier and manually enter them in.

Still sounds APN related. Have you checked with your carrier what the APN settings should be?

With what you will install nougat? Odin or ota?
There are 2 possibilities:
1. Smartphone already installed csc not your region, this sometimes causes the code to malfunction
2. You have supercopy (hopefully not).
Try to use odin, will be caught later results

I use odin for the install of Nougat, when it was on 6.0.1 I saw the phone model and it was G935FD, but only detect one sim and had signal, now detect 2 sim the other is no signal, is there a way to fix it?

Try again to flash nougat firmware for your country.
In the meantime, take a look at the imei information via setting. There is 1 or 2. more importantly see physically, have how many card slot sim

Sometimes using SmartSwitch emergency recovery can solve the problem. Try it that way. If that does not work, maybe someone else knows better who can help you
