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.

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

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.

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.

i installed custom rom and still have no 3g ? solution any1 ???
Hello! So i have a Note 4 910H version, it is a great device and until friday evening i had nothing to complain about. I have flashed it with Sweet rom and that also worked great no problems at all. Well here is the story. I was using my note in my car when i noticed that i had no signal and it would not connect to GMS, so i restarted it.... Still the same, i went into mobile network and to my surprise i could enable LTE And it actully worked i was using 4g. But the signal is terrible and it is always losing signal. The battery is also terrible after this.... It wont last nearly as long as before, maybe worse than half the time. I also encountered problems when unlocking my sim card, I try to enter the code to my sim but then nothing happends.... Sometime it says Unlocking sim but still goes back to the enter Sim code page... It takes like 50 tries until i manage to unlock it...
Anyone know what the ***** Is going on? Thanks in advance

Try to re-flash the stock ROM from sammobile and see if it gets back to normal.
Open Phone INFO ★Samsung★ app > Menu > 'Firmware Browser' to download the stock firmware for your device and flash it via Odin.

Ya forgot to mention to check with "Phone INFO ★Samsung★" to know your CSC and product code to download the correct stock firmware ROM from sammobile for your device's region. I didn't try the in app Firmware Browser before, maybe it's also a good option for you to try it out.
Realy did you get 4g LTE on 910H? Explain how did you do it?

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

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.

DISCLAMER: I AM NOT A DEVOLPER AND MAY NOT BE ABLE TO HELP YOU ON YOU DEVICE. UNSUCCESSFUL ATTEMPTS TO FLASH FIRMWARE ON THIS DEVICE CAN AND WILL BRICK YOUR PHONE. BACK UP EVERYTHING IN EVRY CONCIEVABLE WAY.
After days of trying to do this with all the outdated guides and miscommunications and edits in post i decided to try and make a streamlined guide to help others.
NOTE: If your are looking for anything else other than a stock bloat free unlocked firmware then look elsewhere.
Also if you are using rev 1 booloader then this will ireversablly upgrade you to rev 2 bootloader not a real problem just a note
Download 3B's patched Odin 3.13 https://drive.google.com/file/d/17wH1YHcGsOCxbDGYDoy9VlnqO_Xi6IOm/view?usp=drivesdk
Download samfirm.exe
https://drive.google.com/file/d/1XdboeTqk8pSZyJQVt-IHVHFfznJ9eOQk/view?usp=drivesdk
Thanks to @zxz0O0
If you can't find your own drivers don't do this
1. Extract B3 Odin
2. Extract and run samfirm.exe
3. Make sure auto is checked use SM-G955u1 as model number and XAA as country code then search. It should find you the absolute latest firmware
Hit download and choose file destination. This can take a while.
4. extract firmware.zip
5. Run 3B's Odin and add file to there respective locations. I.e. Ap file in Ap slot etc. Use the non home CDC
6. The only thing you need ticked in Odin are already set by default
7. Boot phone into download mode power+bixby+volume down while the device is off
8. Read the screen that pops up very carefully and decide to continue at you own risk by pressing volume up
9. Connect phone via USB 2.0 port do not use a USB 3.0 port it will not work
Make sure Odin recognizes device if it doesn't then u have a driver issue
10. Press start and wait patiently
11. Phone will reboot it self setup device and insert sim card. You will probably get a notification say phone not allowed a quick call to the service provider you trying to use is all that's in order here
12. Enjoy your carrier unlocked stock SM-G955u1 on your preferred network
I AM NOT RESPOSIBLE FOR ANYTHING YOU DO TO YOUR OWN DEVICE YOU WERE WARNED.
So this gets rid of all bloatware?
From my knowledge, Verizon does not, and has not ever carrier locked their phones. Seems like a lot of trouble just to debloat.. Am I missing something here?
Any idea why it stucks at "SetupConnection.."
This worked GREAT! My Verizon S8+was working fine on AT&T before I did this, but I was stuck on Android 7.0. So thank you so much for this. There's only one thing that bothers me is in my drop down menu there's a notification that says "Sprint OMADM Checking Device Status." Which really isn't a big deal, it's just annoying. Another thing I worry about is, i'm using it on a GSM network, is it actively searching for a CDMA network at the same time and draining my battery? Any input would be appreciated, and thank you again!
I have a verizon s8 plus does this still work please confirm???

The method will be similar just need the proper firmwares for your device
This being quite an old post I was wondering ...
I am currently on G950USQS5CSB1 with CSC XAS/XAA/VZW.
Currently I have no carrier bloat (good), I am on Mint with no issues (good) and I get prompt OTA's I assume for carrier VZW but I lack wifi calling which I would like (bad).
I have downloaded G950U1UES5CSB2 for G950U1
Will this work using the 3B modded Odin as described without having to flash the combination files?
normal and Prince Comsy Odin both failed.
Thanks
edit: Took the dive .... worked great thanks, now on G950U1 and have wifi calling and VoLTE
This is great, minus one thing, it installed facebook on my phone, which I didn't have before and never wanted and it won't let me uninstall it..
I'm hoping you are still monitoring this old thread. I have a Verizon Galaxy S8 and followed your instructions exactly (except that I downloaded the files for SM-G950U1 (my current model is SM-G950U). When I start Odin, it gets stuck at "SetupConnection" and never goes any further. Thoughts?

Yea. I just switched to Verizon. You should be able to just pop your sim in and it automatically carrier switch. Most of these are multi carrier

I typed in the error you gave me and saw a few sites with no box fixes. Normally if you can get to the menu I don't see root being needed. But I may ne wrong since I've never seen this error
This would be great if it worked. However I have my doubts. You would first need to have the phone be from Verizon or be on another carrier and *unlocked* first before changing any CSC using the US OPEN firmware which allows you to simply put a sim card in and switch carriers by swapping sims and letting Samsung reconfigure the phone. The BEST setup is a SPRINT phone.. unlocked.. then converting to U / U1 firmware. You then have every possibility when it comes to carriers sitting at your finger tips!
Good Luck

Your post dont even make sense. The Verizon s8 at the time came sim unlocked. All you had to do was swap the csc. But worked unlocked out of the box. Why would a sprint device be the best setup. All the us s8s are identical. Sounds like you come from LG which is true on devices and versatility. Not Samsung.
i have this samsung s8 i bought off ebay, its unlocked but stuck at searching. i have resetted the network in settings, and tried mannual search which showed an error. wifi works but mobile network and data doesnt work or comes on.
.** it reads the sim on the phone and shows the sim application but no network. i have searched the forum but havent found a solution yet. please help
