Baseband, maybe? - Samsung Galaxy J7 (2017) Questions & Answers

I am a total newbie to rooting, please be as thorough as possible. I am on the AT&T network but currently in Taiwan. I purchase a Samsung J7 Max (sm-G615f) baseband g615fxxu2ara3. AT&T is not recognizing my IMEI number in their system and suggest that I update my baseband in order to receive the AT&T software. The baseband that I need is J727AUCU1AQK6. I am told that this can be done through flashing a ROM. Please help!

[Q] Updating an unlocked T-mobile Note 3 with latest firmware.. Is it possible?? HELP

Hey guys,
Saw a very good deal on ebay india, the seller is selling an unlocked version Note - 3 T-mobile (US), so it can work on Indian GSM carriers.
Now, if you see the description: it mentions:
"The OS Software is Unlocked to Work with all GSM SIMS.
You are not supposed to Update the OS Software as Unlock code is applied to it"
2 quick questions:
1) Can you help me understand what does the seller mean here? The device will obviously be running on JB, so i wont be able to update it to the officially released Kitkat? Will manually flashing a firmware from say Sammobile, revert the unlock code and make the device useless?
2) Buying a US phone for Indian use.. Will i miss out on any features? or will it be a problem in any way??
Please help me out guys

Change verizon rom to international rom

Hi people,
Can i flash international rom on a Verizon galaxy S5?
If yes, how can it be done?
Thanks!
To install international G900F rom, must be bootloader unlocked:
Same way as flashing a normal kltevzw/G900V rom, find a klte/G900F rom and flash it. Any incompatibility warnings are probably outdated, but be careful, and remember, you can't make too many backups.
Just know that you won't be able to use CDMA networks (Verizon is CDMA).
To enable 4G/Phone service in other countries, works with locked bootloader:
You're stuck with the G900V rom. If you're just looking to get support for extra bands in other countries, look into GalaxyTools by Idoneapps. It can give you international support on most existing roms, stock or not. Kinda hard to use but you'll get used to it.
Both methods will most likely require some APN settings modifications.
If your cat suddenly gets eaten or you need clarification, I'd be glad to help.
(You weren't too clear on your request - I didn't know if you wanted an international rom or international support, so I tried to include both.)
I have G900V model but I do not have verizon services in my country. I wanted to get rid of verizon rom as it's of no use to me. Therefore I was looking for a intrenational varient. I am running MM6.0.1 with rooted and bootloader unlocked. Will flashing a G900F rom again lock the bootloader.
How to proceed withave the process. Please help.

S7 Edge Firmware modified Help

Hi Guys,
Looking for some advice on a S7 edge i got scammed with.
I bought what i thought was an Australian Model S7 however i wanted to update the Firmware and ran into a heap of problems for the following reasons.
Bootloader
G935VVRU4API3
PDA VERSION
G935FXXU1BPIA
CSC
G935FXXU1BPIA
BASEBAND
G935VVRU4API3
This phone is Obviously a Verizon model that has had the firmware changed so it shows up as G935-F when its actually G935-V.. there is no Verizon software showing up in the phone too.
I want to at least update the firmware so what should i do?
Load 935V firmware which will load all the Verizon software
Load 935V US firmware
All i want is to update it and try avoid loading the Verizon software.. OR go after the girl who sold it to me and get my money back..
Any ideas what can be done?
I have the same issue..... if it worked for you in anyway plz share

I am unsure whether I need to change my firmware or not. I have the galaxy s8 at&t carrier unlocked variant. about 3 months ago I flashed the unlocked firmware on the phone so I could get updates. I'm using Walmart family mobile which is (MVNO) of Tmobile. I want to continue getting updates without bricking my phone. What should I do?
https://www.xda-developers.com/samsung-galaxy-s8-note8-bootloader-odin/
update to CRB1 from https://samsung.firmware.science/
My baseband version is G950U1UES2AQL1
My model number is SM-G950U1
I don't see either as an option on the link. any help?

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:
SM-G975U1_1_20190225093814_9wyh9qbuyg_fac
AP file name for reference:
AP_G975U1UEU1ASBA_CL15445662_QB22243196_REV00_user_low_ship_MULTI_CERT_meta_OS9.tar
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.
