S4 i9507 Flashing + CSC

So my S6 had an unfortunate trip in the lake, and I'm going to resort to my sisters old S4 (I owned one too, but I totalled it).
Mine was rooted and had GPE loaded on it.
My old model was an i9505 and noticed that my sisters is a i9507 which is a strange variant (assuming its 4G+).
Anyway, when she had it, the phone constantly overheated and would constantly reboot. We returned for repair many times, each time showing no signs of issue.
What I would like to know is;
Would i9505 roms suit this phone? Or would I have to make do with stock.
And secondly, I am with telstra and the S4 is with virgin (OPS). Is it as simple as flashing a i9507 ROM from telsra on it, or do I have to do something else? This is for the CSC of course.

Is the phone sim unlocked? I recommend sim unlocking the phone before flashing any ROMs, especially custom ROMs as the unlock code needs to be entered using a stock Samsung dialler.
CSC doesn't really matter if the phone is sim unlocked.
Stock firmware is here: http://www.sammobile.com/firmwares/database/GT-I9507/

Hmm stock firmware is only 5.0.1 and not for the carrier that I want. It's been so long since I've modded (since I've had stock S6 since I bought it). Can I change the CSC on that rom, or would it be locked to Optus.
Anyway I've put in my Telstra sim and it seems to work for the moment, picking up the telstra network and changing the APN's to telstras (maybe there is a CSC in the phone for TEL too?).
Just would like to know now if I'm able to use a GEL or AOSP rom for the i9505.
Thanks for the response.

The firmware should not matter. The CSC files are a customization of app for a particular carrier. There are 3 carriers in Canada (Rogers, Bell, Telus) for the s4 and I can cross-flash the firmware with no problems. I would be surprised if the phone can't work with Telstra if it is unlocked.
According to these specs, the 9507 uses a snapdragon 600 chip which is the chip used in the i337m and 9505: http://www.gsmarena.com/samsung_i9507_galaxy_s4_with_s600_spotted_in_glbench-news-6571.php

Carrier restrictions

Hey, just a quick question. I'm thinking of getting the N910F after formatting my N910C's efs partition (;_ and I'm a bit reluctant since it's sold out in all of my country's stores BUT it's available through my carrier. What I'm asking is, if I buy the phone from them (just the phone, no contract since I already have one) is there a chance the bootloader will be locked and if it is, will there be a way to unlock it? Also, will it be sim-locked? If you don't know, how could I ask?(This isn't a local branch of t-mobile, verizon, sprint, etc. etc. large US carrier. It's a domestic government owned company so I don't know about that on my own).

-As far as i know Only Verizon and at&t have locked bootloaders (You wont be able to flash anything)
-Now a days samsung has started partially locking bootloaders on all its devices (910C + 910F) Any note 4 running COJ5 rom has a partially locked bootloader, which means you can not downgrade to 5.0.1 or 4.4.4 but you are still able to root and Flash coj5 based custom roms, recovery etc.
-If you buy a phone from local carrier you can turn it on at the shop go to settings>about> Check if the baseband version is COJ5 or COL or anything newer if it is then you wont be able to downgrade to earlier versions of stockrom but you can still root and do stuff.
- you can ask the company reps if the phone is locked to work on their carrier only (you can pay them to sim-unlock the phone)

Swapping GT-N5120's mainboard into an SGH-I467

I am tired of dealing with SGH-I467's (AT&T only) locked bootloader. It makes installing custom ROM impossible. Now I'm thinking of buying and swapping in a mainboard from SGH-I467M (the Canadian version is bootloader UNLOCKED) or GT-N5120 (international version).
1. will this give me an unlocked bootloader without any other hardware change? I know I probably have to swap in a new modem code, but with an unlocked bootloader, any software change is possible
2. will the mainboard from GT-N5120 work in a SGH-I467? I know SGH-I467M's mainboard will for sure work in SGH-I467 because the only difference is the latter has a locked bootloader. Unfortunately, SGH-I467M's mainboard is hard to come by, but GT-N5120's is still available. Although the LTE bands in N5120 are overseas and SGH-I467 has AT&T bands, are they really different hardware, or same hardware with different software?
Any comment is highly appreciated. Thanks
[Updated Feb 9th, 2018] Now I don't think it is doable at all to download SGH-I467 or SGH-I467M's modem code to a GT-N5120 hardware even if the bootloader is unlocked. I have a Canadian Galaxy S4, SGH-I337M (bootloader unlocked, unlike the AT&T version). Since my carrier is U.S. T-Mobile, I tried to download T-Mobile's modem to my S4 thinking it may give me better data rate. Odin prompted Fail! (Auth) and S4 showed Secure Check Fail! After some googling, I realize regardless of unlocked bootloader, these phones/tablets are engineered to check if authorized modem codes are being flashed. I know for sure my S4's bootloader is unlocked because I have installed TWRP for recovery.
Since GT-N5120 has international frequency bands, turning it into a North American tablet is DOA if another carrier's modem code cannot be installed. If anyone questions why a custom ROM can be flashed to a phone/tablet with unlocked bootloader, it is because a custom ROM seldom comes with the modem code!

Firmware from SM-T377P on AT&T SM-T377A Tab E?

I was just curious if it was at all possible to flash the firmware from the T377P model to the AT&T model (T377A) because it seems like most of the development is for the T377P. Has anyone achieved this yet or attempted flashing any other model's firmware to the T377A?

Flashing SM-T377P firmware on a SM-T377A wouldnt work, because the T377P uses a Snapdragon 410, not an Exynos 3475 like the T377A uses. Flashing SM-T377T (T-Mobile) firmware might work, since it uses the same Exynos CPU as the T377A

I'm just curious what the best alternative firmware would be to flash (if possible at all) on this tablet because there's absolutely zero development on the AT&T variant (T377A) of the Tab E. Preferably a firmware that's been successfully rooted, etc.

Unfortunately nothing can be developed for the T377A because the bootloader on that variant is locked, so that means we can't do anything to the device, even with Odin. If there was a way to convert a T377A to a T377T, or if there is engineering firmware for the T377A, then maybe development is possible.
On another note, I found somebody's backup of the Nougat firmware for the T377A: https://mega.nz/#!eHJSUCoZ!54BXNlvrL6RJfEHzS4qNOj3eqwCpxSrzrI2l_IqHe84
Contains the AP, BL, CP and CSC files.

Can you please describe what you did to unlock it? I've tried 1000 things and nothing seems to work

You have to request the unlock code from AT&T, there's a slight difference between doing it for phones from your own plan or someone else's phone (you received as a gift or purchased second hand). They walk you through the process for each type of equipment so it's relatively smooth.. I just want to remove the bloatware and have a security update more recent than tree years old. This is my main gripe with AT&T, stuck with questionable bloatware and a vulnerable version of Android (and it's locked down so tight no one can fix it on their own).

So you were able to unlock the bootloader by following an AT&T tech over the phone?

Obtaining ATT Specific Functions On An Unlocked Phone

Hey Everybody,
So I've come to realize that my unlocked US S10+ on AT&T didn't have VOLTE or Wifi calling as options in the communication/call settings menus. this is pretty disappointing as it seems that using the unlocked phone with Verizon you get these features, and they make a decent impact on my use of the phone.
My understanding is if I flash the ATT firmware to the phone I would get the functions, so being an amateur I followed some simple guides to SamFirm AND ODIN, and downloaded the ATT CSC firmware for my model number. However after going through the Odin process and resetting my phone it is still showing the same Software information as prior to my installation, and I do not have the features.
I saw a thread on the board stating that the ATT firmware isn't available yet, so I'm not sure if what I downloaded was actually any different than what is on my phone,and my phones "Service Provider Software Version" did already have ATT in the description, which is a bit confusing to me.
Am I correct in understanding the only way to get the features would be through a firmware flash? And would anyone know if I had flashed the right firmware, and what the original firmware CSC would be for my model if I needed to revert?
My information is:
Model Number:
SM-G975U1 (S10+ ceramic white 512GB - Unlocked US)
Service Provider SW ver.:
SOAMC_SM-G975U1_OYM_ATT_PP_0018
R38M205LY2B
ATT/ATT/XAA
Firmware file obtained from SamFirm:

If it's anything like the S9 was, you can't just ODIN the firmware/CSC. You'll just get the bloat with none of the features you want.

I've heard this as well. If you want those features on a Samsung phone, it has to be at&t branded. I ordered an at&t phone from Samsung since I make good use of wifi calling. It works fine on my unlocked P3XL but no dice on the Samsungs.

I have the same phone and service and when I went to update my imei they told me it could not find the phone. So I was without lte/4g for a day until I gave them a imei to a s8 active. Now I have data at least

So I have the same service provider software, on my unlocked s10+, however when I went into an ATT store and looked at a branded S10+
I noticed the service provider software version to be : SOAMC_SM-G975U1_OYM_ATT_PP_0033( thirty three at end),
so anyway to update the service provider version? does that come from the SIM ??

I have an unlocked S10 plus and I flashed the AT&T Firmware. I now have VoLTE and WiFi calling unlocked on my phone using AT&T. You need to make sure you flash the U version of the firmware, not the U1 one. Unlocked S10 is using the U1 firmware already so flashing that one again changes nothing.

Where did you get the att firmware?

I kinda doubt it but did any of you with unlocked phones that flashed the AT&T firmware get any better service? I've been considering it to get VOLTE but just wondered

I followed this thread https://forum.xda-developers.com/galaxy-s10/how-to/att-ota-ota-updates-t3909697
At first like you I downloaded the wrong version and nothing changed. I finally flashed G975USQU1ASBA and now have VOLTE/WIFI Calling and of course all of the bloat. But at least those two functions are working. Make sure that you complete a clean flash when I did a dirty flash I had problems sticking on the loading screen.

I believe you just need to call in ATT to take care those carrier specific features .

Which firmware can I flash with Odin to my S10+ Xfinity Mobile unlocked to get AT&T OTA updates? Currently have ASF7 flashed from the latest unknown firmware uploaded to Sammobile. I flashed w/o USERDATA. I just want to be able to get future OTA updates as I just switched my carrier from Metro by T-Mobile to AT&T. I was using U1 US unlocked firmwares on my Note9 & S10+ but want to use carrier perks now with AT&T.

What's with AT&T being the only ones to not release update files? You would think they all would be required to release them. More AT&T customers need kick up a fuss about it.
