Hi, I have a demo phone Samsung S10+ model G975XU.
How can I put it in retail mode? So i can factory reset the device and have access to all the settings?
Also, the unit has no Imei recognized? is there a way for it to have a sim card and use it as a phone normally?
What are the options?

1. Shut down the phone, pull out the battery and the SIM card.
Check SIM card in another phone.
If the SIM card is corrupt, get a new one from your mobile provider.
If it is OK, put in into your phone again, put the battery in again and start the phone again.
2. If that does not help, try to toogle between flight mode on/off.
Wait some seconds to be sure that the phone really switched the mode.
3. If that does not help, have a look here (=> http://forum.xda-developers.com/showthread.php?t=1131950) to get a new modem/phone/baseband file, and flash it with Odin to your phone.
4. If that does not help either, you may have to flash a new ROM to your phone and do a factory reset.
For Official Firmwares have a look at Intratech's thread => http://forum.xda-developers.com/showthread.php?t=1075278
There you will find everything you need and a description of how to flash.
Good luck !
I bought an unlocked s9+ from ebay and later found out that its country sale came from Panama. My canadian GSM network does work on the device, but certain apps like samsung members show spanish promotions or samsung pay not being available.
Can the csc code and country be changed in this case?
Model: SM-G9650
CPU: Snapdragon 845
Did you setup the phone and then inserted your sim card? I believe that now that you have your sim card in, if you make a factory reset to your phone, your csc will change to the csc of your country/sim card.
I live in Greece, I bought my phone (international exynos s9+ unlocked) from an international seller and the csc was ITV (from Italy). I inserted my sim card, factory reseted the phone with the sim card in, and when the factory reset was completed my csc was changed to EUR (Greece).
You can try it.

Have you tried this method, and has it worked?

No, I haven't however I would ask Lukesky1313 since it's his method. It would seem it's either this option or flashing a custom ROM which will eliminate functionality of Knox, Samsung Pay, Secure Folder, Samsung Health and possibly others.
I recently unlocked my Galaxy J7 Sky Pro from the tracfone carrier (called them, got two codes, put them in and device said it is now unlocked).
Now when I try to insert a different sim card the phone seems to have no service, even though the sim card is recognized (asks me for the pin and logs in properly). In fact that sim card is a prepaid european one, from the german carrier O2, but since J7 Sky Pro can do LTE connection I though that should work fine?
What do you guys think, is there something I could do to fix the issue?
My exact model is:
SM-S727VL
And android version is:
6.0.1
One kind of annoying thing is that even though I unlocked the phone, it still shows the tracfone logo on startup. Maybe the firmware is preventing the european sim card to connect to a tower? Is there some "international" version of firmware I could update to to make it work?
Thanks for any suggestion!
I purchase a like-new condition Samsung Galaxy S9+ phone from Amazon Warehouse for international travel coming up in couple days. I figured I would have a better chance of getting an authentic phone from Amazon than from ebay sellers. I received the phone yesterday, and here is the situation with the phone:
- The box of the phone says "unlocked by Samsung"
- The sticker on the back of the phone has the model # SM-G965UZBAXAA and IMEI number of a factory unlocked phone
- The actual IMEI of the phone however shows model # SM-G965UZBAATT, which corresponds to the AT&T carrier locked phone
- When I turn on the phone, it shows T-mobile screen and has T-mobile apps on it
How do I determine whether this is a AT&T phone, or a T-mobile phone or something else? Unfortunately, I do not have either TMO or ATT sim cards that I can use to check which network the phone works on. How do I know whether this phone is unlocked and if it is will work internationally? I am not sure how to explain the imei of the phone coming up with ATT model number, yet the phone shows TMO screen.
Please help as I need to get this resolved today, and don't have time to purchase another phone. Thanks much in advance!!

put any sim in it and it should work these phones are multi carrier means all the us models are the same if its att imei id say its unlocked since obviously last used was t mobile but if you put any sim in it other than att it should accept it and not say unnsuported sim and or ask for unlock code
to further this as i said the us models are all the same. They have a file called CSC which determines carrier based settings you can put in a tmobile sim and it will repersonalize for tmobile then swap to att and att will show up..
Its the way of the future and actually quite nice as one firmware pretty much covers all carriers other than specific user data which is that carriers apps
it may be unlocked obviously the listing was wrong but xaa is factory unlocked for sims, You can reflash xaa if it is unlocked for non carrier branding,But id put any sim in and see

Thanks for your response. So if the previous owner put a T-mobile sim in the AT&T phone, then would it show the T-mobile screen at startup, and also have the T-mobile branded apps?

Thanks again! Is it safe for me to do a factory reset on the phone? I wasn't sure if it was rooted and whether a factory reset might brick it. If I do a factory reset, what would it restore to - the AT&T or TMO configuration, or something else?

I downloaded the phoneinfo app, and here it what it shows:
Firmware's CSC code: XAA
Active CSC code: TMB
IMEI check shows model ending in: ATT
That made me highly confused as to whether this was a AT&T phone, a T-mobile phone or whether it was originally sold as factory unlocked.

So originally it was a att device. Who ever used it used it on tmobile but on xaa which is debloated unlocked

Under Service Provider SW ver., it shows TMB/XAA/ATT
I am trying to understand what this means, why would it show TMB, XAA and ATT? Does it mean the phone was originally AT&T, then someone installed XAA firmware on it and used it on T-mobile. If that is true, is there a way for me to verify whether the current installed firmware is XAA?

That is correct. You see it now. The third csc code is the original device. The second is what csc you have running. And the first is or was sim inserted.
Look in settings about phone and software info. At the bottom somewhere it should show you

Yes, what I pasted above is from about phone->software info. It shows the service provider sw version as TMB/XAA/ATT. Thank you!!
Hi,
So this device I bought from facebook marketplace and was told it's fully unlocked.
After inserting a different SIM, the device works for a minute, then shows an error saying it's not a verizon SIM and disconnects from the network.
I contacted Verizon and they're telling me that it's unlocked but I guess something in the firmware that prevents me from using the phone. I did a factory reset, now the phone setup won't finish without a Verizon SIM card. it stays stuck on that screen.
Is there a custom firmware that I flush this phone with and be able to use the phone?
Please advise.
Thanks.
Verizon A02S unlocked but not able to use on other networks. Need help unlocking
Hi you have to remove headwind mdm thanks
I have the same situation. Bought a Samsung A02S and it's from Verizon and was factory reset.
It boots to "HELLO" screen but won't let me initialize the phone without a valid Verizon SIM. I put an old Verizon SIM and it says "invalid".
How can I boot this thing to get to settings etc. to unlock it from Verizon?
