The phones that you purchased are all "gray market" meaning that they have been unlocked using methods not supported by the original manufacturer. They were never intended for sale outside the U.S. (Whether this is illegal or bot is not a question that I will try to answer.) If you try to update them, you will lose the unlock (they will revert to Sprint) and you will need to unlock again yourselves.
This is happening with many phones, not just the S6. You can read about it here: http://www.androidauthority.com/beware-the-grey-market-retailers-648562/

HELP! 4g LOST / not working
THE SHORT OF IT: I flashed a custom ROM & kernel. They didn't work properly, so I flashed my nandroid to get back to rooted stock. NOW I HAVE NO 4G or signal of any kind (wifi works)!!!!!!
THE LONG OF IT:I'm in South Korea using the Galaxy Note 2 on the carrier LG with their U+ LTE service. As far as I could see and have been told my phone ONLY uses 4g (no 3g or other options to check). I was advised to flash a Tmobile or ATT Rom (I chose the Tmobile AOKP) as our U+ phones don't have their own Roms & Forums and I flashed a custom kernel from sjkoon a developer posting kernels that work for our phone. Others have done the same thing and reported no problems. After flashing, the new Rom & kernel, the phone booted in the Google startup helper I could not gain access to any signal or wifi to access or create a gmail account.
So, I nandroided back to stock (rooted, mind you, using chainfire's exynos exploit) but my 4g won't work, only wifi does. So, I have NO way to make/receive calls. I've verified a number of pieces of information through various avenues and have the following:
PHONE INFO
My Access Point Names says "LG U+" with "internet.lguplus.co.kr" underneath. There is no option to change it or edit it, just a radio button with no other options (is this is fine?). I was advised in another forum (http://forum.xda-developers.com/showthread.php?p=36895160#post36895160) to change mmsc's value to http://omammsc.uplus.co.kr:9084, but I dont' know where that option is to change it, or if this is a problem.
I also used the the "Phone Info" app and got some of these readings:
In Telephony, have a Device ID, my Network type is 3, Sim State 5, it shows I have a SIM operator and country, Serial Number Subscriber ID, etc. The only things that MAY be strange (I don't know what their original values should be) are that Call State, Data Activity and Data State are all 0 and my Network Operator Name, Network Operator and Network Country ISO are just blank. Even if I wanted to change any of these I have no idea how...
PLEASE HELP & THANK YOU!
It's strange. I spent the night/morning searching forums for a solution but not sure exactly what to do. Please, help me or point the way to fix this issue if you know how and thank you very much. I'm willing to buy you a beer or buy your newest app, say thanks on all your posts for the next month, whatever! Hehe. ...:crying:
Hi,
I am very new to android and reading lot of posts online but saw mix response, so posting it here for more clarity.
I got LG G2-sprint version rooted phone from one of my frnd in USA. The phone is working good with Vodafone India. I have below mentioned queries
- If I factory reset the phone,
1) will it lose the rooting?
2) will it get locked to sprint and I lose to connect to Vodafone India?
- I see update available notification. If I update the phone, will it get locked to sprint and I lose India operator connectivity?
- I Can not see GSM only mode for 2G only use (just to save battery consumption by 3G at times). Is there any way. I network settings I see only 4 options (Global, LTE/CDMA, CDMA, GSM/UMTS).
Pls help.
first of all, questions dont belong in the the development area.
2nd, factory reset shouldnt cause you to lose root, however it may not place nice. (i remember bricks from lg optimus days)
3rd, i wouldnt take any updates or anything unless you have a backup of everything including apns and all the apn settings. if you factory reset, it will try to go through sprints hands free activation.

If you got it from your friend in US, who might have been unlocked the phone directly through Sprint then you are good to go, you don't need to worry, if he hasn't got it unlocked through Sprint then search Sprint Development section you will find information how to unlock it. But factory reset does brake Root(in other words you will loose root) & secondly, while you are on root DON'T EVER UPDATE LG G2. Otherwise you'll have a soft brick.

Thanks brothers for your response. I again got two different answers
1st one - Factory reset will not break the rooting
2nd one - Factory reset will break the root.
One query is still unanswered
--> I Can not see GSM only mode for 2G only use (just to save battery consumption by 3G at times). Is there any way. I network settings I see only 4 options (Global, LTE/CDMA, CDMA, GSM/UMTS)
Hi Team.. pls help...on GSM ONLY setting with LG G2 Sprint version. I simply can not see GSM ONLY mode in network/mobile settings
Hey XDA World,
I just bought (3) AT & T Note 4 devices off ebay, stating to be factory unlocked & for use on GSM networks (such as T-Mobile USA)... I have (2) questions.
# 1 - How do I get rid of the AT & T Boot sequence / firmware on the device.. I really want either T-Mobile, or International screen
#2 - How do I get Lollipop updates without locking the phone ? Can I get them via OTA on T-Mobile network ??
Sorry for the newbie questions, but want to make sure I do the right things to avoid an expensive mistake. Thanks in advance for the reply
Thanks,
Rick
Question 1. These phones are unrootable at the moment so know messing with system files and it's possible that they will never be rootable.
Question 2. I doubt you will get lollipop update ever unless you put AT&T Sim in the phone. Updates are carrier specific and AT&T OTA will never complete without there Sim. It will error out every single time.
Good luck
I have been trying to unlock a Samsung Galaxy S9 T-Mobile model SM-G960U to use it on local carrier (Ecuador) with no luck (I have use doctorSIM service too)
After booting the phone a got a message:
Security error.
This phone has been flashed with unauthorized software is locked. Call you mobile operator for additional support. Please note that a repair/return for this issue may have additional cost.
Trying to use the T-Mobile device unlock app, then a screen shows up with a message "Your device is network locked at this time, which prevents it from operating with other compatible wireless networks. To inquire about your device's unlock eligibility please continue" but after tapping the Continue button there is not option of permanent unlock, I got a message saying: "Server not responding. Please try again later."
I have trying to install de stock firmware G960USQU7ETG3_G960UOYN7ETG3_TMB (Android 10) downloaded from Frija using the Odin tool, doing a factory reset, wiping the cache, doing a NAND Erase with Odin, but the security error still shows up.
The device is able to browse on websites using Wi-Fi, what should I try next?
paid services are the only way. You won't get help on that here. They employ a different type of lock than most devices.
@OP
I don't know all the ins and outs of tmobile unlocking (not a fan of their service). However, I recently had in hand a paid off s9+ which was still locked. I ran the unlocking app multiple times over the course of a few hours. Each time it came back with an error (unsuccessful or something to that effect) when I tried the permanent unlock. For each attempt the tmo sim with active service was still installed. Eventually it did finally unlock. I'm not sure if a tmobile sim with active service is a necessity. Probably is as it has to authenticate the account for unlock eligibility.
I have a Verizon Samsung Galaxy S9 Sm-g960u and needed to switch to T-mobile. I had no problem switching from one carrier to another because I was told that all Samsung Galaxy S9 devices came factory unlocked. I bought a T-mobile Samsung Galaxy S7 Note from a friend and tried using the T-mobile app to unlock the phone I think there was a problem so he just called T-mobile and explained that he sold his old phone blah blah blah and since he owned it they just unlocked it right over the phone, no problems or issues.
Hi,
So yesterday I successfully unlocked my Galaxy A50 from Three network and ported my number to 48 network. Went to a phone fix shop to get the phone unlocked and it took about 20 minutes (cost me €25). Everything about the phone and 48 network works fine. However, when I went into Software update in my settings and tried to download and install the latest software update, I receive the message "Your current software version isn't supported. Visit a service centre".
I never had issues with updating software before and after checking online it seems that maybe the software updates are carrier locked (to Three network) and that if I want to update the software I would need to put an active Three SIM into the phone.
I rang back the guy who unlocked the phone and he said that people never come back to him with this issue after unlocking their phones, but if I wanted he would be able to manually update the phone and in the future it should update automatically, but this will cost €35 as he said he may need to backup everything and upload it again and it's a lengthy process.
It's either that, or find a Samsung Service Centre in Ireland (can't find any on website) or put a Three network SIM in any time I want to update.
Does anyone have any experience with this? Would really appreciate some help!
