Help with US Cellular (don't delete this time)

I have the Galaxy S5 for US Cellular. I have tried flashing roms and they will boot. However, I get no service. I know the roms are based off the 900F which is the international version. I cannot get anything except for wifi to work. There has to be a way to do it. I've looked around and realized I need to ask for help. I can and have flashed kernels (blaze works). Please help!!!! Also, it is annoying when I ask for help and my threads are deleted.

[Q] installing Tmobile rom to i337

Hi,
Currently I have a i337 galaxy s4 which I am using with tmobile sim card. I made it unlocked by ATT before I switched to tmobile. It has baseband UFNI1 and Android 4.4.2 installed. I managed to get it rooted using the Odin software, so I can use the tethering with the tmobile.
Now I am trying to find a way to use the Wi-Fi calling. I searched it a lot and figured out that I need a tmobile rom installed but it quickly got very confusing. It looks like what you need to do also depends on what android version you are using. For some you need safestrap, change the kernel for some you don't. For some you have Wi-Fi issues and need to change the modem etc.
So, I am trying to find the easiest and safest way that will make the Wi-Fi calling work. I don't necessarily need the very latest android version or the fancy custom roms etc,I only need something that will work without any issues. I am perfectly fine with a tmobile stock Rom if that's the most convenient way.
So,I would really appreciate if someone can help me on this. It would be great to have a set of noob friendly instructions. Thanks a lot.

Hi There,
Were you able to root your device for Wifi Calling. I followed the instructions of http://forum.xda-developers.com/gal...nvert-i337-to-m919-wifi-caling-t2896719/page6 and went into the same issue. After TMOBILE stock rom, the phone does not boot. I was able to install the first rom and then able to get onto the latest version and able to use phone again with AT&T latest software update (android 5.0.1). Actually, this is the version I have when I started rooting.
If you find any solution, please let me know as I am on the same boat with you on installing TMOBILE ROM using the other thread.
thanks
Ram

You cannot install a T-Mobile stock ROM to an AT&T device. Samsung has safeguards in place to prevent it. You would need to root and then install a custom ROM, which on an AT&T is difficult to do with its encrypted bootloader.
However, this is not the appropriate location to ask this. Questions related to AT&T devices belong in the AT&T S4 forums.

[Q] Help regarding SM-G900P

Hey everyone, I been looking around the forums here and other sites and have learned a lot of info in pieces but I really need help with a particular issue. A friend of mine gave me a Sprint Galaxy SM-G900P (Galaxy S5) which is (of course) CDMA with GSM compatibility. Im unsure at the moment what service he was wanting to use but I know it is a GSM carrier (US) because he has a SIM he wanted to use. I owe him a favor so I told him I would try. Besides going the route of purchasing a unlock box and unlocking the phone with that, I discovered the SSU apk which SIM-Unlocks the phone. I downgraded the phone from Lollipop 5.0 stock to Android 4.4.2 KitKat (G900PVPU1ANE5) with ODIN. (FYI, i was stuck in download mode with no recovery mode for a week before finally getting one to work, and so happen to be that version that went through)..... I downloaded SSU and it unlocked the phone and I switched mobile network mode from CDMA to GSM Units. (NOTE: it says 4.4.2 and up will not work with USA carrier SIM cards without downgrading the Modem but I have not tried just yet) Im about to Root the phone but here is where my question comes in. I have read of people flashing roms to get their phones to work with certain carriers and other functions. Will rooting help me out at all? I guess IM asking if there is a ROM that I can flash onto the phone to enable the use of whatever carrier he is wanting to use with it. I know thats most likely useful in the situation, but Im awaiting that answer as we type. ANY help would be greatly appreciated ))) Thank you all.

Anyone? :/

The problem is the APN and you can not modify it. Contact your carrier and see if they can assist.

ehrn i purchased the phone it was perfect. connecting internet was showing 4g.. but when i installed this original Verizon rom it became difficult.. now i am unable to root and install custom recovery... please guide me to root and install custom recovery TWRP and i want to install custim rom.. please help

@dipankar.c2bs
You might look into getting your CSC "sales_code" changed. I'm not sure if that is entirely the problem, but it is likely related. Even the USA Verizon ROMs come preloaded with databases that are used to provide custom parameters for a variety of carriers and locations world-wide. (See the file /system/csc/imsprofile.xml for example) I suspect the way this information is actually used is through the "sales_code" CSC value, but I'm not 100% sure of that.
I'm guessing you want "INS" or "INU" instead of VZW
What you currently have:
Code:
getprop | grep -i csc
If your handset is supported by Airtel, one of their technicians will probably know how to do the CSC change, possibly without even rooting the phone.
If it not supported, they probably will be under orders of their employer not to help you at all. But, is is easier for them to give you advice face-to-face, rather than over the telephone (subject to monitoring), if that is possible.
A question to ask - a form of social engineering - is this: "do you know of someone in the area that can help me for a small fee?"
[EDIT]
There is one other possibility for a non-rooted phone. I really don't know if this would work (I am speculating here), but the basic idea is to apply a CSC for a closely related device Model (a SM-N90???? Qualcomm model, hopefully for CDMA/LTE) that is for your country and carrier on top of your existing ROM using Odin. Get the CSC file from Sammobile, and:
- wipe the entire phone using the stock recovery. (You can remove the external SD card first if you like)
- boot the phone, shut down, boot into stock recovery.
- wipe the entire phone again in the stock recovery
- boot into Odin and flash the CSC in the CSC slot.
- boot the phone; do a minimal configuration and see if you have the service you want.
Note that @donc113 s advice given above is the right place to start: ask your service (Airtel) to help you before you try anything yourself.
good luck.

when i purchase it was good... there was 4g indicator also.. no verizon boot screen.. but now it dont works..

One of your friends who installed the stock ROM apparently didn't understand the consequences of what he did. Stock ROMs set the APN for Verizon. Did this friend happen to make a backup before he did the ROM switch?
