hello i'm itching to mod my g925t however i'm having second thoughts. Here is my predicament.
I bought my galaxy edge here in the Philippines , used. I was surprised when i look on the phone's setting and said that it is indeed a G925T which is a T-Mobile version, however it is working on my network I.E ( i can make calls, text and data internet). I have a question, When i change, root, my kernel, rom and pretty much any on the software side. Will it lock itself? thanks. Because if it'll lock i'll just deal with it not having the perks of modding it. For reference though , i updated the phone and reset it via SMARTSWITCH and it doesnt lock itself, its just that t-mo apps are still there . I can still call, text and use mobile data.
Samsung G925t edge s6
android version 6.0.1
kernel version 3.10.61-8273934
baseband version G925TUVS4EPH2
I have t mobile and i live in india..
I had same thoughts...
Anyways i went ahead and rooted, installed recovery and even flashed a custom rom many times with clean install. Nothing has happened yet..
I havent flashed stock back even once via odin but i think its safe to say it will remain unlocked
If your 925T is already unlocked, it'll remain unlocked regardless if you root flash a new ROM, I think I've unlocked it remains unlocked. I've had a few unlocked phones and they never got"relocked" after modding them.
Hello. So, I was using an unlocked Tmobile S6 Edge Plus on AT&T. I was psyched to give the S8 Ported ROM a try, but since flashing the device is now network locked. Rom is awesome, but now cant use as a phone. Is this normal? Any help is appreciated. Also, I figured I could just restore from original backup, but now still network locked.
Here's the situation:
I'd like to take advantage of the Samsung trade-in deal but want to buy the correct phone to give me the most options and i'm finding conflicting things on reddit and even here, can someone answer a few quick questions for me:
1) Can i START with an unlocked S8+ from Samsung and flash the TMO firmware if i want? Or any carrier firmware for that matter (selling purposes)?
2) If the answer is no, you can't start with an unlocked S8+, does that mean i have to get a TMO version of the S8+ to be able to flash the unlocked firmware and/or flash back to the TMO firmware?
3) Lastly; if i get a TMO S8+ and flash the unlocked firmware can i still flash the TMO CP to get 256 and MIMO? I did that with my S7 Edge however i started with a verizon version which was already unlocked - flashed unlocked firmware but TMO modem.
3b) I also saw someone on reddit who said they bought the verizon version, flashed the unlocked, then flashed the tmo.
I appreciate the clarification, there are just so many threads and a lot of different answers it's hard to sort through them.
Thanks in advance.
I have the same question. I ordered my wife a T-Mo S8+, because she doesn't care about unlocked/bloatware, etc.
I ordered myself a US Unlocked version, but now I'm.wondering if I should've ordered a T-Mo version.
Couple reasons:
#1 T-Mo version has RCS and video calling. Not a big deal, but cool nonetheless. Apparently GearVR doesn't work on the unlocked version?
#2 The unlocked version only comes in black. I have a couple options with the T-Mo version and could always flash the unlocked software.
#3 Some people have had issues flashing BACK from the unlocked firmware to T-Mo, so if I want T-Mo firmware on my unlocked version, will I have issues flashing it?
I don't really care about colors. Black is fine. And if I can freely and easily switch back and forth between T-Mo and unlocked firmware on either version of the phone, then it doesn't really matter which one I get. Until I know which firmware works best for me on T-Mo, I'm not sure which version I really want to use.
They fixed the GearVR on the unlocked versions; of the 1000+ posts i read i did see that.
Also, i did find this thread but haven't had time to go through it all:
https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487
Based on the title, i would ASSume you could do whatever you'd like. I don't care about RCS or video calling so that's not a big deal to me. I decided to take advantage and nabbed the unlocked version, it was the cheapest and since i can probably find a way to flash whatever i want on it i took the risk. I have a couple old phones that getting $200 in on trade is worth it, i went with the S8+ and will probably do it again using my wife for the S8 trade in. Decide which device i like the best and sell the other.
The trade-in was the main incentive for me too. Coming from Nexus and Pixel I'm used to unlocked devices as well.
And I've been pouring over threads today, but some threads are 100+ pages long, and just too long to read or even search through.
Usually the community finds a way with flashing firmware so i'm confident. I'll come back and update this thread when I get it, the only thing I would like to do is flash the T-mobile CP modem for 256 QAM and 4x4 mimo. Other than that, Unlocked firmware all the way

Same here. I received my S8 plus unlock version. I would like to convert totally to t-mobile. Instructions so confusing though.

All you need is the firmware files (BL, AP, CP, and CSC_OYM for new carrier flash, CSC_HOME for manually updating same carrier firmware) for the version you want to move to and the modified odin (prince comsy). A quick search will turn up all you need here on xda. Just like the snapdragon S7 and edge, changing which carrier/unlocked software you have is just a 5-10 minute odin away. All versions are compatible regardless of which carrier/unlocked software you start with. Ignore all of the "how to change to XAA" etc. Just find the modified odin and firmware you want to use and flash.
EDIT: To clairify, all snapdragon software versions are compatible with any snapdragon S8 or S8+.

There's no longer a need to flash the TMO cp. I have flashed the unlocked software on my TMO S8+ and unlike the S7e using the unlocked firmware, CA, 256QAM and 4x4 all work fine. The phone enables these things based on the sim inserted. I did a test with my wife's S7e (unlocked using TMO modem file) and my S8+ side by side and speeds were identical, and my S8+ reports CA using bands 2, 4 and 12. The S7e on the unlocked cp (modem) would not have CA and have slower download speeds.
The only thing you lose is the video calling within the phone app (same as the unlocked S7 and edge) when flashing the U firmware to the S8. But unlike with the S7, since you no longer need to flash the TMO CP file to get 4x4, CA, etc, you can now take OTA's for the unlocked version and do not have to manually flash the newest firmware in odin.

Infinite Thanks! So based on your post, i'm not going to do anything. I hope your message gets out there because there is a lot of confusion on various sites including Reddit about the CP modem with the S8/S8+.
That's great news.

Thanks. So finally i flashed tmobile firware on my unocked version s8+. Now i have video calling enabled and also tmobile logo while boot up. As u said i have my end results showing TMB/TMB/XAA NOT TMB/TMB/TMB. But i guess from your post i dont have to worry about it. And also they got rid of enable VoLte toggle but it can be enabled with nova launcher not a big deal.

Are you saying that you can't accept OTA updates if you flash a carrier CP with unlocked firmware? Or are you saying that accepting an OTA on unlocked firmware will overwrite the carrier CP?
I bought a carrier unlocked Samsung Galaxy S6 (SM-G920P) online that ran Android 5.1.1. I used it here (not in NZ) and I wanted the Android 7.0 Nougat update but I couldn't update it OTA due to the fact that my phone was supposedly running on a custom software. So I flashed the (SM-G920P) 7.0 Firmware for Sprint but now I can't detect my mobile network. Also on the back of my phone, it says at the bottom "SM-G920R4". What do I need to do to get my mobile service again? A carrier unlocked phone can't lock again right?
If I'm correct, the g920r4 is on US Cellular
I've read that the Galaxy S9 hardware is identical for all carriers in the USA.
If I bought a factory unlocked Galaxy S9 can I flash it to the carrier I am using (Verizon, Sprint, T-Mobile, AT&T) to enable carrier specific software and features? Can I flash it back to the unlocked firmware?
I already see a thread about flashing the unlocked firmware to carrier models so I am assuming there are no issues there.
Can one carrier model be flashed to another carrier model?
No, bootloaders are different, with the S7 there was an unbranded U firmware that was compatible with most of them, unlocked firmware will be that one for the S9, but no you cannot just flash different device firmwares to the wrong model
I was able to flash the ATT rom onto my Verizon S9. I got a VZ s9 from work but I'm on ATT. For the most part it's worked great, I had done the same thing previously with a Galaxy S7. I say for the most part b/c I am on here tonight to post a question myself about the fact that I'm getting a delay with MMS messages. I imagine it has something to do with the APNs I have setup, but I can't seem to figure it out.

Did you have to flash to the U1 software first?
I do think that is what I ended up doing... tried to go directly first and it kept failing. Got fed up and decided to just try and put the bone stock rom on it, and that went on really easily.... so after using it like that a few days I tried to drop the ATT rom on it and it worked without issue.

Yes, but you need to go to the u1 firmware 1st then to the other carrier firmware. Also make sure you avoid the newer firmwares with the new bootloader, as the unlocked model and certain carrier models don't have the new bootloader.

yes u can.. u can flash between U and U1 firmwares no problem..
normally ud b correct tho but since s8/s8+ it has been ok.. just cant flash 9600 or 9650 to a U or U1 device

That'll be why I still thought that then, coming straight from the S7 > S9
Had many members flashing the wrong firmwares thinking they could do that and bricking their S7s / wondering why ODIN failed

I tried downloading vzw firmware G960USQS3ARI6 to my unlocked sprint s9 and still not vzw flashed. want to do this so can have voice over LTE. Any other steps im missing? flash went through but still sprint
As soon as Firmware ver. 3 came out for the G960U1, I was able to flash it to my Sprint G960U and finally have VoLTE, WiFi calling and stable LTE for MetroPCS. Used samkey to unlock it from Sprint. My phone is actually performing much faster without all of Sprint's bloatware hogging my RAM and storage space. I can confirm that OTA updates still work the same...I received September's security patch (current) with no problems. Device is still official status and Knox hasn't been tripped.
A lot of people think you can just flash the carrier firmware of your choice and boom, it works...I had the same thought process....that's not the case. You have to make sure that there is a matching firmware version for the carrier you want to flash to, as well as make sure the G960U1 firmware version (the unlocked version of the S9's software you have to flash first before even carrier flashing) is the same version of what is installed on your phone now. It's easy ya'll......just READ lol.
I'm in love with my phone again thanks to XDA. ?
HAPPY FLASHING!

Hi, I got one unlocked G960U1(G960U1UES3ARI1) and downloaded new fireware(G960U1UES3ARI1-SPR) from sammobile, but after flashed SPR ROM successfully, the info on the phone still shows XAA, anything I missed here? Thanks!

Well first off, you have the unlocked phone. I don't. My G960U is originally from Sprint, so I'm not sure about carrier flashing regarding the G960U1. I thought it was supposed to provision itself after you put the sim in, and the associated carrier apps will download since it's the unlocked model...but I may be wrong...

I know so many people have already answered your question from some saying No to others saying Yes but you need to Install U1 first and Bla Bla Bla.
I want to give you one specific answer: With S9 you can any Carriers firmware you wish or even Unlocked phone's firmware. You will never have any issue. And you don't ever need to flash U1 or something else before changing carrier firmware you can Flash from ATT S9 firmware to VZW S9 firmware without any issue. You can also flash from U to U1 which is from Carrier specific to Unbranded/Unlocked but only hiccup is original Odin will give you SHA-256 error, which is normal because you are flashing U1 firm to U device or vice versa. This error can easily be resolved by used Patched odin that disabled SHA-256 check. And trust me you will never have any issue.
You will never want to do this but I have gone as far as mix-matching U and U1 firmware together as well. Like flashing AP, BL and CP of U device but flashing CSC of U1 device. and it still works.
hey there, a little late to the party, having trouble with going from a Verizon to a Sprint, even by way of U1. I can't get any of them to work. And I've been told I have to go from VZW to U1 before I went to Sprint. Is that not the case? I'm having a hell of a time getting anything to flash, everything fails.

well, I tried to load the Sprint image from the VZW, no dice. It said it passed, but upon reboot loaded up the old Big Red (even with the Sprint SIM in it).
Anyone have any ideas? This is driving me insane....
