Samsung Galaxy S6 (SM-G920T1)

I got my phone at Rent-A-Center, and got T-Mobile service on it. The phone worked fine for a while, until all of sudden I got a message:
Security Error
The phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair/return for this issue may have additional cost.

So, I followed some instructions online, hooked my phone to the computer, and upgraded the firmware through Kies, which gave it a metroPCS ROM. I had been suspecting that someone flashed the phone before I got it from Rent-A-Center, but this really sealed it. So, I called T-Mobile, and T-Mobile tried to tell me that the phone was now locked to metroPCS and I had to call them. metroPCS said that they would not help. So, I had to do some work on it myself. I tried to find a T-Mobile compatible ROM, and before I did that I wiped the phone completely. Nothing will flash to it now, and it's in a bootloop. None of the flashes succeeded except that I was able to get a custom recovery on it. I can access TWRP and Download mode, but I can't successfully flash anything. Can I get some help?
Edit: I meant to append "Boot Looping" to the end of the title when I finished the posts body. I apologize.
Edit 2: I was finally able to get it out of the boot-loop by flashing a new bootloader, and flashing the stock ROM. However, it's back on metroPCS and still has that same message. How do I fix this?

Download Samsung Kies and try to do a firmware install by providing your model and serial number.

Flash it with the latest Metro PCS firmware, then you will have to get a unlock code from unlock base or your preferred unlocking company. After that it will work on T-Mobile and every other GSM carrier BUT you must keep the metro PCS bootloader and modem. I use a 920T with 920T1 bootloader and modem on the att network. I am running the tmobile twisted six rom + kernel with great success.

Well metro uses that unlock app also now so I'm not sure that method even works anymore these days. Also you have to make sure the bootloader number is the same or above the metro firmware your trying to flash. Bootloader number is the fifth from the last number.

I downloaded one from a tutorial and it failed on Odin then I downloaded 2 more metropcs firmwares from sammobile and they failed. I'll try to do what you said, find one similar to my bootloader.

This method seemed to have took place in 2015 and I even saw posts of it working in late 2016. Do you by any chance know when metropcs started using an device unlock app?

Network unlock of Boost Mobile Variant

From what I have read in the ROM forums it appears that you can get around the Boost Mobile network lock by unlocking the bootloader and installing a Lineage based ROM. Can someone confirm this and does anyone know if you can get LTE support of AT&T and T-Mobile this way? Best Buy has them for 79 bucks right now and for that price it sounds like a cheap way of getting very usable backup phone/something to give to the 4th grader to have when she goes over to a friends house. Thanks.

Hey, did you ever get a confirmation on this? Im literally in the same boat, would like to find out!
I didnt read too much and I may be totally wrong, but a quick search told me that I would need to have a working LTE connection on Boost before attempting this, otherwise LTE would not work. If I have to buy a boost card, activate it, then go through all this, I might as well buy the unlocked version for a few bucks more..?
Thanks

Yes, I can confirm. Installing the latest unofficial LineageOS 14.1 on my XT1776 allowed it to finally recognize my Cricket (AT&T Wireless) SIM card. The OEM retail firmware, however, did not work.

Would you be able to link to the threads to install LineageOS? Did you need to activate on Boost before installing the LineageOS?

Just to give an update I bought one at Target with a best buy price match (I had some Target gift cards). Up and running with a T Mobile sim and Resurrection Remix in less than 45 minutes including download everything and installation minimal ADB and Motorola drivers. Coming from an LG G5 I am impressed at what 79 dollars buys. I was interested in an Honor 7x but is hard to justify the extra 125 bucks. Thanks to everyone for the great guides and help. The hardest part was figuring out how to eject the Boost mobile sim card.

Did you have to bootloader unlock and root first to do it? I just ordered a phone from BestBuy. I remember for the Moto E4 Verizon phones that you had remove the prepaid sim before you even power the phone on otherwise it gets locked to Verizon for 6 months. Any gotchas here?
BTW, anyone who want a stock rom, this might help? https://forum.xda-developers.com/showpost.php?p=75968092&postcount=14

I'm not sure I ejected my sim before turning it on just to be safe.

Does anyone know if this phone once unlocked and LINEAGEOS is installed will work on Verizon?

I would think that it would be fine. It's no different than what I did except it's fir a different network. Mine works with t-Mobile and at&t sims. Haven't tried a Verizon one.

Verizon is CDMA, but I guess it should work since I think Sprint uses their network, too.

So just to confirm, do we have to activate Boost SIM and provision LTE first before unlocking bootloader and flashing LineageOS? The Lineage thread says LTE won't work if we don't provision LTE first before flashing.
I'm on T-Mobile currently and might switch to Cricket in the near future. Thanks.

I took the Boost Mobile SIM out and inserted my T-Mobile SIM before I even powered on the phone for the first time. Notification was there that showed it was invalid (as expected). I connected to my wifi and updated the OS to the latest one. I unlocked the bootloader in the OS setting and by getting the code from Motorolla. Installed TRWP, backed up the stock OS, wiped and installed LineageOS. SIM card worked on T-Mobile immediately and got LTE. ¯\_(ツ)_/¯
EDIT: I'm working on another phone and I noticed after it's booted up and I'm past the new install setup steps that it looks like it's connecting to the Sprint network and provisioning even without the Boost SIM card installed. I connected the phone to my wifi during the initial setup so I can update the stock formware before unlocking. I have no idea if that matters. I'm guessing the Linage thread is correct. I suppose it would be bad to boot to fastboot first, unlock, flash recovery and flash lineage without ever first booting the phone up with the stock firmware.

Thank you for the quick reply. Although, I decided to jump in and got the Moto E4 Boost Mobile version for $50 and went through the same process

AUS DUAL SIM SINGLE SIM issues & XSA STOCK FIRMWARE

Unfortunately here in australia the telcos have blocked dual sim capabilities for this phone as well as blocking us from purchasing unlocked dual SIM devices from samsung themselves under a contract. i however heard from 3 seperate samsung reps that it is a CSC issue which can be resolved by rooting and removing the given telco CSC (in this case optus) and replacing it with an unlocked version. is this correct or does there need to be 2 device IMEI on the phone for dual sim to work??
I've downloaded the XSA firmware for us Aussies and will be uploading it to MEGA soon. But can any one tell me wether it's simply a CSC ISSUE or will I just have to live with single SIM??

I don't think changing your CSC to XSA requires a root. But yet to to find a working solution myself. I tried flashing the XSA stock firmware, but it doesn't change the CSC from OPS to XSA. I'll try flashing another country firmware and move it back to XSA and see if this changes the CSC to XSA.

Apparently you need to put a different SIM in for 5 mins to make it unbranded I'll be trying DR.Ketans rom and see what the difference is than maybe I can get it to work. We still need a dual SIM tray also

Ah cool. I'll try that later tonight if i have time. True that we will need the hybrid sim tray. I wonder if we can get a hybrid sim tray from Samsung to keep the waterproofing intact. Bit worried with the quality of the aftermarket products in relation to the waterproofing of the phone.
I found this thread about changing CSC for Note 8.
https://www.google.com.au/amp/s/for...eo-firmware-downloaded-directly-t3765512/amp/
But everytime I flashed the combination file, ODIN stucked at odm.img.
Let me know how you go.

Hi
You MUST download the combination rom for NOTE 9. DON'T USE THE combination ROM for NOTE8.
You can find the combination rom for SM-N960F via below link.

Hi there,
I actually downloaded the combination rom for note 9 from gem-flash.com. For some reason when I flashed the AP and Home_csc, it always stuck at odm. Tried this several times.
Not sure where I went wrong.
I'll try flashing to another country ROM and then follow the steps on your original thread and flash using the combination rom for Note 9. All i want is to change the CSC from Optus to XSA.

tried to flash AP only and it worked. however, on the factory IMEI, *#243203855# doesn't give me the list of the csc. When I tried to flash the AP and home_csc or csc it always stuck in odm.img. Not sure what's happening.

Did you guys get this working at all? I'm in the same boat with a telco note 9, either going to return it and buy one outright or try get it working. i ordered an additional tray with the hybrid sim slot.
where have you found the various stock australian roms?

Sammobile.com...
Has all the latest Stock ROMs for all regions...
Thankfully I bought from Samsung (pre-order)... Came with Hybrid Sim card holder and 2 IMEI's though I have yet to try...

Cool. I'll give it a go now that I have it and if the new sim tray and flashed stock rpm doesn't work Telstra can stick it and I'll get from Samsung too...

What i've done so far:
Got a hybrid sim tray. Doesn't reject the second sim.
Flashed with odin and the stock XSA rom. Didn't work.
Flashed with Dr Ketan using TWRP. Doesn't work.
Tried to enable the sim manager setting using package disabler. Enables it but no way to access the settings.
Used a shortcut app to try to access the sim manager setting but crashed out.
About to try a different rom...
It seems to be software related only.
If there was a way to access the sim manager setting/software...

Where did you get the hybrid sim tray?
I'd assume the lack of an imei for the second sim would be the issue

Looks the firmware is same for OPS/TEL/VAU and public version.
I believe the logic should be same as Note 8, it's controlled by EFS not only CSC number, you also cannot change the HOME CSC.
So you have to decrypt the EFS, write the second IMEI, then you will have the dual SIM function.

You still cannot connect to network even you can open the sim manager app.
You don't have the second IMEI which is required for network.
The rom is same for Australia and New Zeland, you won't able to change your CSC if you just flash the rom in ODIN.
You have to use combination rom to change your CSC, but I don't think you can change your HOME CSC, you only can your normal CSC.
Dual sim function is not controlled by CSC if the logic is same as NOTE8.

OK, been a little while coming but I FINALLY got around to testing my Samsung bought XSA Note 9 for dual sim cards.
Both sim cards work fine, Just means my sd card is now floating around out of the phone and my backup phone has no sim...
Made and received calls off both sim cards.
So, the dual sim Note 9 bought directly from Samsung Australia with the XSA firmware CAN use both sim cards. It does have 2 different IMEI numbers and both work...
Glad I got the Samsung phone over the Telco distributed phone as it seems they have actually crippled one of the primary features of this awesome device...
Cheers...

Desperately Need Help - Samsung SM-N960F/DS + T-mobile PUK and other issues.....

Hi. I am a complete noob when it comes to rooting Android.
**************************UPDATE************************************************
THIS ISSUE HAS BEEN SOLVED. PLEASE SCROLL TO POST #89 ON PAGE 9 TO SEE THE SOLUTION.
https://forum.xda-developers.com/showpost.php?p=77950935&postcount=89
***************************************************************************************************
I bought an *unlocked* Samsung Note 9 N960F/DS (Exynos 9810) international phone from a seller on ebay brand new and sealed. Received the phone yesterday (10/19/2018) and popped my working existing sim card from my iphone 6 with T-mobile into the new phone and it *worked*.........except no wifi calling.
Since my house has terrible reception I really do need wifi calling in order to receive calls (I use Skype for outbound). I decided to root and install Detonator (tekhd) even though I've never done this before. Somewhere along the line I messed up and installed the latest LUX ROM because I misred Tekhd's guide on Detonator (my fault).
Here's where I stand now: I found a stock ROM for this model (N960F/DS) and reinstalled it using Odin3 v3.13.1.
After a successful flash when I insert my working T-mobile sim I get "SIM network PIN blocked. Enter SIM network PUK."
Here the Service Provider SW shows XEU/XEU,XEU/MYM
I get the *same* message when I insert a spare T-mobile sim I happened to have that was confirmed as available with T-mobile customer service. If I take the working sim out and put it back into the other phone it works without a problem. I think that rules out the sim cards having issues.
Earlier when I had the phone rooted and Detonator installed (and working), I got a different message when I inserted the SIM:
Network Lock: This device can be remotely unlocked if eligible.
Please use the "Device Unlock" application to unlock the device.
Make sure the device has an internet connectivity to use the "Device Unlock application".​
Here the Service Provider SW showed TMB/TMB/MYM.
I tried looking for a T-mobile Unlock App apk to download but could not find a recent one. I would get a "Device not supported" error. It seems T-mobile has taken it off the Playstore.
Now, I can't install a stock USA ROM from T-mobile because those ROMS are only for the Snapdragon versions and I have the Exynos chip. I was given two unlock codes over the phone with T-mobile customer service to try and unlock the Pin lock but they both did not work.
Do you think an unlock service will be able to provide me with a valid "Sim Network PUK" code? I'm happy to pay for the service if I can just get the damn phone working. I've spent almost $770 on this phone and in hindsight should just have gotten the T-mobile branded phone for $100 more. I'm really at a loss as to what I can do to rectify this situation.
Also in hindsight I should have done more research before purchasing the phone and also should have backed up my partition in TWRP........You live and you learn.
The irony here is that I had an unlocked phone.....and now it has somehow gotten locked.........by the carrier whose SIM card is working perfectly fine......in a different phone. The device was paid in full btw.
Any help is greatly appreciated. Thank you in advance.

I've spent almost $770 on this phone and in hindsight should just have gotten the T-mobile branded phone for $100 more. I'm really at a loss as to what I can do to rectify this situation.
Also in hindsight I should have done more research before purchasing the phone and also should have backed up my partition in TWRP........You live and you learn.
The irony here is that I had an unlocked phone.....and now it has somehow gotten locked.........by the carrier whose SIM card is working perfectly fine......in a different phone. The device was paid in full btw.
Any help is greatly appreciated. Thank you in advance.

this is a first. I always though once the region lock was lifted it couldn't be relocked( to me it seems to be a region lock issue, which if it is you need to make a 5 min call on region soil... good luck)
anyways check on your box there is a sticker with model and serial . find what carrier or region its from and grab that firmware and flash it. might want to factory wipe everything (including cache) in the recovery before booting it up indownlaod mode to do Odin flash.
also remove sim before wiping/ flashing, let it boot and do the initial setup then insert sim.

I did wipe and reinstall the stock rom with the sim removed. The strange thing is..........I get the same message if I insert an old, blank, unused t-mobile sim into the device. Plus the working sim works fine in my old phone. So how could it be that the sim is locked?
There is nothing on the box that says anything about a carrier. This was advertised and sold as a factory unlocked phone which by all indications it does seem to be. The only thing on the box that says anything about country is that it was manufactured in vietnam.

no sticker with device model or anything? not even in the back of the phone when it was new? a white sticker

Yes there are stickers. But it is not associated with a carrier, specific region, or country. I just see IMEI info on the sticker on the back of the phone and S/N.

I was a dumbass and did not backup. I had zero issues other than no wifi-calling before trying to root and flash detonator...... Thank you for your help.

I went to a site with all "official" downloads and I don't see anything for ZBDMYM........

https://samsung-firmware.org/model/SM-N960F/region/MYM/
did you flash one of these?
these should be the original firmware U1 and the lates U2 which if you flash wint be able to downgrade bootloader but shouldn't be causing rhe sim lock issue.
flash U1 first and see if it fixes your issue. then try the October U2 just for fun
you can also download it using samfirm tool
enter 960F and MYM in settings it should also be a faster download then the web links

My baseband version currently shows N960FXXU2ARH7 and Service Provider SW Ver. shows XEU/XEU, XEU/MYM. I will try loading U1 first and see what happens.

ok so it's too late for U1 . ure phone is already on U2 latest bootloader. so flash the October build
but be sure to wipe all with no sim before flashing
and in Odin fill in all slots and for csc use CSC but not HOME csc file.
good luck

yeah might as well use tarp. and erase all. but before, did you sift through internal s or ext s for an efs backup that detonator might have made automatically?
check for a folder called .backup and or for a file like:
efs_backup.img.gz
efs_backup.img
or anything similar

No, but I did download Dr. Ketan's tool to make an efs backup. But that was way later in the process....so it wasn't the original efs directory......It was after I flashed my current "stock" rom. I'm going to try and find another site to download since that one will take 2 days on slow speed......
Btw what does the ZBD mean? MYM I figured is Myanmar......

I am using Samfirm and found this;
Model: N960F
Region: MYM
File: N960FXXU2ARJ1/N960FOXM2ARJ1/N960FXXU2ARJ1/N960FXXU2ARJ1
Verions: N960F_1_20181001162540_w0h1lv73k8_fac.zip.enc4

If Install this ROM, does this mean my phone will be region locked to MYM again? I'm definitely confused on this......

well ure screwed either way. the goal is to restore everything back to stock and see if you can get a line working
btw was there a seal on the box that you had to break in order to open the box when you first got it?

S10 and network branding / firmware for VoLTE / Wifi calling

A few years ago, this was possible to do, change the firmware of the phone to another brand/network, i did this to my S5 years ago.
Can this still be done?
What has happened is i've got a phone on the EE uk network (as at that time, my sim card was an EE sim).
However, I have now changed over to Three UK, (better signal at home). However, i can't use VoLTE or wifi calling, which we really do need.
Can i sort this by uploading the three firmware via odin to the phone, will that solve my issue? Or is there more to it than that? or less to it these days?

You can try it out without any risks. If odin fails it will stop and give you an error. So feel free to try it

A little different. But the same...
Just SIM Unlock the phone first!!
Then flash the CORRECT (Exynos or Snapdragon) Firmware **AP,BL,CP,CSC AND USERDATA** For your Model AND Carrier with a PATCHED Odin.
Or an Unloked Firmware AND Userdata....
Either way, you will end up with all the carrier features you want.
Good Luck!

NOT 100% TRUE, IF you flash the wrong Carriers Frimware, it may contain a BOOTLOADER that is of a higher level than the Firmware YOUR CARRIER supplies. If you have a snapdragon model this COULD BE a HUGE problem!
Some bootloaders, like on the phones sold in the USA, can NOT be Downgraded!!!
This could mean you are stuck with (example) Sprint Firmware on a phone you want to use with T-Mobile BUT NONE of the T-Mobile features will work!!! And you cant go back to Tmobile firmware now because the bootloader for the firmware is a lower level then the one currently installed...
If that happens you have to literally WAIT until T-Mobile releases a firmware with a higher level bootloader, WHICH SOMETIMES NEVER HAPPENS!!
Good Luck!
