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 there XDA Members,
I have a massive problem and I hope someone in this forum is able to help me, I have an S6 Edge SM-G925F, I recently broke my phone and sent it to repair they repaired it and installed firmware that is non EE therefore I lost my WiFi Calling feature, I was like okay let me just flash the EE firmware unfortunately due to the bootloader they installed being newer then the one from the EE firmware it wont let me install (SW B: 2 K: 4 S: 4) this means that the firmware I am trying to install is older and samsung bootloader wont let me, now I want to know if there is a way I can:
1) Downgrade Bootloader or get it to accept this firmware
2)Have EE WiFI calling another way
3)Install EE WiFi calling onto the phone somehow
My phone is on version 6.0.1

I would say look for a ee firmware that doesn't include the Bootloader. That way the firmware should load, most mm firmwares will run as long as you have a mm bootloader.

Folks,
Happy 2018,
Quick one:
I bought a locked ATT SM-G955U & reflashed it to a SM-G955U1 (currently on the latest December Security update) but the issue here is that despite doing this and eliminating ATT bloatware my phone continues to show Service Provider SW Ver. 9889544437594c3958 XAA//ATT
My buddy have an unlocked SM-G955U1 out of the box & there is no Service Provider information on his phone settings. He also gets all updates via OTA without issues, whereas I need to flash using ODIN manually which is not an issue for me but will be easier to get the OTA updates.
My phone is almost perfect but is there any possibility of flashing the specific CSC file for the SM-G955U1 on my SM-G955U transformed to a SM-G955U1?
I guess this was explained clearly.
Thanks for your support. XDA is the best.
SW, if listed as xaa/xaa/att...is what you wanted. The last three are always hardwired. I bought a T-Mobile U1 and switched it to Verizon. So mine now says vzw/vzw/tmo. If I read correctly in previous postings, you may still be forced to update manually, if on ATT. I believe...
If you flashed the files correctly in ODIN, then you wont see the provider version at all. It doesn't appear in the unlocked firmware. And you'll also get OTAs just fine. I know, because I bought a VZW 955U and flashed it with the unlocked 955U1 software.
Yup I can confirm too. I flashed the unlocked firmware to my spring g955u.
I can get OTA updates same with unlocked phone
Precisely .. I need to flash the correct one...
Where do I get the unlocked firmware ?

Did you use regular ODIN or the modded Odin?
Where do you get the unlocked firmware from?
I got it from sammobile & the SW version persists

Check snap+ thread
Was on ATT, unlocked, now on T-Mobile. Phone is 3 yrs old, sketchy; shuts off randomly, has issues. Want to flash firmware, but Sammobile doesn't have 915a. Since it's unlocked and on t-mobile network, can I flash with t-mobile firmware? Can you put any carrier's rom on an unlocked phone? Sammobile has "usa" firmware with no carrier designation.

Thanks.

Did you find a solution? I flashed the firmware uploaded by makki666 found in another thread on updates for Note Edge from at&t. Right now am using 6.0.1 but may revert to basic 5.1 1 to get temporary root & get rid of bloatware (have not figured out what is worse, outdated OS or bloatware). If you found a better solution, please posr
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!
Greetings,
I am a new user here. I just bought Galaxy S10e and I really like the phone, but the problem is that I ordered it from USA (I live in the Republic of Georgia). Originally the phone was from AT&T, but the seller had it unlocked for any GSM carriers and it works fine with my Georgian sim card. The only problem is that I do not receive any software updates. It is stuck on Android 9 and One UI 1.0. When I try to check for updates, it says that my software is up to date. The same happens with Smart Switch.
I tried Frija and Odin. My CSC is G970UOYN1ASD9 and PDA is G970USQS1ASD9. There is no way to download firmware for my own country's CSC, because there is no firmware for SM-G970U (Snapdragon chipset), in Georgia they only sell Exynos ones officially. So, I tried to find updates with CSC ATT in Frija and it does not give me anything. I tried XAA and XAS (which is for unlocked phones) and still nothing. I tried TMK (I think it is for MetroPCS) and USC (This one is for US Cellular) and also TMB (T-Mobile) and they do have Android 11 firmware. But now I am afraid I will break something if I install above mentioned firmware to my device. Or maybe I will not break anything by changing the CSC, but maybe there is also a chance that if I install the above mentioned ones, the phone will get locked on these carriers and I won't be able to use my sim card. Is logical, or am I just overthinking it?
Any help would be really appreciated.
Thanks in advance.
don't flash your nations CSC- that shouldn't matter. Snapdragons LTE bands should be good enough to work internationally
go and reflash a USC or XAA rom with patched ODIN... I had to do this for my phone and OTA started working once it was on the correct CSC
you could even flash it to the latest firmware if you wanted too.

Thank you for your answer.
What do you mean by correct CSC? I believe, my phone is on correct CSC now. I have already pasted it and in about phone > Software information > Service Provider it says ATT/ATT/ATT. But it seems that ATT doesn't receive updates outside US.
I cannot seem to find firmware for XAA/XAS, there is one for USC but I have already downloaded TMK. Is there any difference if I install USC or TMK? (TMK is MetroPCS).

Greetings,
I have already updated to Android 11 using U1 XAA firmware and it works great. I used Frija and then Odin if anyone wants do to do this. Weird thing happened though - when I flashed the firmware and when Odin did it's job, the laptop suddenly shut down and I couldn't turn it back on. I had to disassemble it and unplug the integrated battery, plug it back on and fortunately it turned on again.
As far as your question goes, I am sorry but I cannot check it since I am already on Android 11.

Hi GSamkh,
I am experiencing the same issue as you, purchased an AT&T branded SM-G970U for use in Australia. After you flashed to Android 11 using U1 XAA firmware, do you now receive OTA updates? cheers
