I'm trying to flash my phone but whenever I do it, the software doesn't change at all. I want to change the csc code but it doesn't change. I put the files in for all of the sections. The OEM LOCK is: ON(U)
Edit: I unlocked the bootloader and it says OFF(U). It still doesn't work

I have an unlocked phone on Marshmallow.
Will it become locked again if I upgrade it to Nougat using Odin and the official firmware?

Thank you for the firmware source.
Just to clarify, you flashed only that AP, no additional modem or bootloader files?
In addition, is T-mobile a cell phone provider also in Arab emirates? I did some search in internet and it seems the answer is no.
Would it be possible somehow to compare if your phone and mine have been unlocked the same way?
Thank you for any additional help

No my service provider is Etisalat not Tmobile but i bought this phone on Craigslist and it was locked on Tmobile network so the owner sold me very very cheap he didn't know how to unlock it.
I bought it in 140$ and and it's brand new condition almost untouched.
i used a software in windows pc called "Z3X samsung tool pro v29.2" a cracked version to be honest to unlock this phone permanently.
After that i flashed nougat via odin just in AP tab and still unlocked.
I did not flash modem or bootloader separately because this firmware comes in full package Bootloader+Modem+CSC+System all you have to do is use AP tab and upload firmware then flash it.but remember you have to do factory reset from stock recovery immediately after flashing successfully otherwise it can get bootloop
Even though i try Tmobile sim unlock app that comes pre installed but it didn't worked cuz i don't have Tmobile sim card.
I am not sure your phone situation to be honest but since its UNLOCKED already so give it a nougat shot.
Hello.
I have a Galaxy S7 that I got about 5 weeks ago. I paid to have it in the box but the person got a secondhand one. I am in West Africa but someway somehow I got a Verizon one that is unlocked for any carrier. Anyway I checked and some functions were not working. Private mode is not working, there's no software update option anywhere (I checked developer mode) and some features I've seen on YouTube are not even on the phone. I'm stuck on Android 6 and can't update so I made up my mind to flash a custom ROM but turns out Verizon's bootloader is locked which will make such a task impossible. Some days ago though, I found out that official Verizon ROMs can be flashed without unlocking the bootloader and this raised some questions which I want to ask here.
Here's the info at the about phone page
MODEL NUMBER - SM-G930V (there's Verizon on the back of the phone so I think this is true)
ANDROID VERSION - 6.0.1
BASEBAND VERSION - G930VVRU4API3
BUILD NUMBER - MMB29M.G930VVRU4API3
1. Can I really flash a stock Verizon ROM for the Galaxy S7 without bricking my phone and with a locked bootloader?
2. If I were to flash a stock Verizon ROM will the phone be locked to Verizon again? I'm asking this because this is the only phone I have and I'm supposed to use this for 2 years!
3. Should I flash the same baseband version or will another Verizon one work?
4. If all the above questions are true, where can I get official Verizon stock ROM for my device?
If you have any questions for me please let me know.
Thanks

Yes, you can flash Verizon stock firmware without issues, as long as you are not trying to flash an older Verizon stock firmware than the version you already have. In other words, you can upgrade, but you can't downgrade.
As for flashing a west African firmware, Nn, Verizon devices have a locked bootloader, the locked bootloader will not allow you flash anything except Verizon stock firmware. Attempting to flash anything from another region or from a different device will only result in a soft-bricked or hard-bricked device. You can only flash the Verizon stock firmware for your specific model number.

Hi! Thanks for replying! So where can I get a Verizon stock firmware that is an upgrade of mine and what region should I download from? Also which version of ODIN should I use?
Thank you very much!
Hello, I have an unlocked Galaxy Note 20 Ultra from Verizon. I am wondering if it is possible to fully convert this device to work fully with TMobile I was specifically wondering if it's possible to use TMobiles 5G Network on this device. I have flashed the U1 Firmware to the device but it never showed me an Option to choose my carrier or anything like that, and even though the Signal shows 5G whenever I turn a speed test or view the cell info it pops up as LTE
You need to change your device CSC to TMB and flash TMB U firmware, not U1.
You device currently shows VZW/VZW/VZW in your screenshot.
It should read TMB/TMB/TMB, or at least VZW/VZW/TMB.
The SIM card itself will determine what network you have access to.
Be careful though as you have now flashed newer firmware with the new version 2 bootloader.
So you can only use firmware with that bootloader version. No going back.

If you change ur CSC from VZW to TMB, then it will read TMB/TMB/VZW in your screenshot.
You can only change to TMB/TMB/TMB if you root your phone .

Please note, some codes in original post don't work for some, with latest 10.1 Update.
Using Sammobile, I've seen U1 firmware with a T-Mobile CSC. That way you won't have all the T-Mobile apps or boot screen.
I tried flashing an Australian (G970FXXS9DTK9) anrdoid 10 firmware but odin wouldn't let me-
phone still works thank goodness. it's on android 11
I thought with an unlocked bootloader I could flash whatever I want as long as it worked for the phone (staying within 970f)
whats happening? how can I flash an english working stock firmware? also can I flash an older firmware or am I still locked somehow from going down or changing country
Hello,
I have an A536V (I bought it used and it's not paid off) and every time I try to flash a different firmware (XAA, TMO...) it just says secure check fail.
The phone should be unlocked because my T-Mobile SIM card works for a few seconds until the signal just goes away and doesn't come back. So my question is, what am I doing wrong? Why can't I flash any other software?
P.S. I used the SamFW tool to change my CSC to whatever was available (on VZW software the only ones available were FKR and GCF, neither of which bypassed whatever stops my SIM from working).
Please help! Thank you!
secure check fail means its either the wrong firmware or to low of a revision than whats on the device as in you cannot flash older firmware But that being said you are bassicly admitting you have a subsidized phone thats blacklisted due to non payment. So no other help will be given more than likely here
Look at this: https://www.androidauthority.com/how-to-unlock-a-verizon-phone-1131315/
"Once you hit that 60-day mark, Verizon will unlock the device automatically. However, you’ll have to pay it off in full if you want to take it to another carrier."
Move to Verizon. Easily solved here. (Well maybe. I don't know what Verizon thinks of that with buying a used phone not fully paid off.)
I have the same question, but I have a Verizon phone that is actually paid off
EDIT
I just wanted to change CSC to remove the ugly Verizon branding on boot
It stayed unlocked when I switched to GCF firmware (XAA was not available since this is technically a hardware revision from the usual A53 5G, this is the A53 5G UW - ultra wideband model)
Anyway I found out from someone else you can use SamFW to do this for free in the ADB tab
