I bought a Galaxy S5 (G900F- International Model) two years ago. It was locked by carrier. I can't use any network sim from my country. So I spend some money to unlock the carrier (Country Unlock - This is what we name it). It was&is on Android Kitkat. Now I planned to upgrade it to latest marshmallow from official update using Odin and it's files. I just want to know Will it lock the carrier again?

Hey guys,
I am thinking to buy a Galaxy S6 At&t unlocked version from the local shop so there's no chance to go to the BestBuy to update the phone because they don't operate in my country and the same thing goes to Samsung, Samsung has a sales offices in my country, not the help centers. I want to know If I buy that phone, I can get the latest nougat update from At&t or If I flash the latest At&t ROM from the SamMobile, does this affect my unlocked phone? Like after flashing I can still use any carrier network?
Hope you got it what I'm trying to say.
Edit: is Smart Switch will help me to update to the latest firmware?
im 90% sure you can use any sim if its already unlocked on any other carriers firmware but i know some of the U.S variants are locked down to carrier specific

My friend owns the same phone and He can use any network sim but that was not the question. I want to know about the update, If I manually flash the firmware will it break the unlocked functionality as the model firmware are only specific for the network.
no it wont break it

Hello,
I live in France and I just bought from USA this phone : T-mobile - Galaxy S7 - SM-G930T- Android 6.0.1 - Baseband G930TUVU4APK1, to use with my european sim card.
Sorry many questions, I'm lost completely, between all the forums and different answers.
It seems even if I buy an unlock code it will not work, with T-mobile the only way to unlock is from the T-mobile device unlock app?
Do you think I can root it or flash a rom to remove all the T-mobile things and maybe I could unlock with a code?
If yes I can only install the roms of Sm-g930T I can find on sammobile website? (looks like only Tmobile firemware) or others for galaxy s7
Or what could I do to unlock my phone?
I'm looking on the forums and I tried to root it but didn't work with CFroot.
It seems more complicated with my usa version because from what I understand the bootloader is locked
Thanks a lot

If you install G930U firmware from sammobile it will still lock the SIM. I have done this with my G930T phone. T-Mobile got the patent of their SIM locking technology which they introduce in Qualcomm phone S7, S7E, S8 & S8+. It is completely different method from other carriers' locking method. Till now there is not unlocking method other than server unlock which cost you $150.
I was afraid about the server unlock, so expensive..
I was hoping if I put a firmware with nothing about Tmobile, and then maybe it will ask for a normal unlock code like on other phones and that is like 20or30$.
Thanks for your reply

Unfortunately I can't. I think the true owner of the phone is required for unlocking it. I need different ways to unlock it. Can I just install another samsung s8+ firmware to this phone?

Can i just flash a rom that is SM-950FD to this phone? This rom has a dual sim feature but the SC-03J only has one sim. Will this work? i mean its okay even if its just one sim i just want it to work on my country.

No. There's no firmware or ROM that will SIM unlock it.
You'll need to have the original owner unlock the phone for you OR purchase the phone already unlocked - no software can unlock it for you.
Docomo and Softbank are extremely strict when it comes to unlocking a phone, you need to have an account with them for a few months, pay off the phone, and you'll be able to unlock the phone. If you don't then having it unlocked *remotely* is out of the question unless you sent it to someone who can unlock it for you.
Sorry to revive the thread after so long.
I have similar situation. I have a NTT Docomo s8+. I have unlocked it as well, it now works with my ATT sim in USA.
problem is the annoying Docomo apps in Japanese.
I am not able to rid of it completely.
Can I flash a US-Unlocked stock ROM or any custom ROM ?
pls let me know how.
Pls note my phone is Snapdragon based, (unfortunately most ROMs are for Exynos version).
Has anyone successfully able to get the beta for Android 8.0 on unlock firmware?
yes ! hurry!!!!
i signed up at 355pm PST. with unlocked ATT s8+ plus (i bought the unlock code on ebay). i bought the att s8+ from samsung dot com, i dont know how to get the code from them, so i bought it on ebay.
UPDATE: try some online unlock service (instead of ebay). some give you the unlock code instantly.
How did you get it?? I have a att unlocked s8+ on stock firmware and want to use it on Verizon

you CANT use att unlocked s8+ on verizon, it only works on GSM carriers. if you want to use verizon, sell the att s8+ and get Verizon s8+
i have unlocked att s8+ when i put in Xfinity mobile simcard which uses verizon towers. my unlocked att s8+ got no signal.
Oreo is out for at&t users anyway, look in the guides section. Apply update from SD. Easy and smooth.

Hi.
I have a routed Galaxy S6, (SM-G920F), and I'm looking for a way to unlock it to any UK carrier.
I'm happy to flash a new ROM if that's what it takes.
I don't know what the carrier is that it's currently locked to.
Thanks in advance.
