I unfortunately locked my unlocked S8+ international version while trying to flash the CSC for T-Mobile and now I can't use my sim card and I have no idea exactly where this phone originated from... am I screwed?

I have a T-Mobile USA SM-N900T currently running [ROM][KERNEL][4.4.2-NE4][SM-N9005]CivZ_FlexKat_Rev3.5
The ROM is listed as "region free" however when I attempt to insert one2free Hong Kong prepaid SIM-card I got a 'network locked sim card inserted' error?
I can't use "Region Lock Away" as it's no-longer functional on 4.4.2 - and I can't downgrade to 4.3 because I assume my bootloader has already been upgraded.
Any solution here?
Shouldn't a "region free" ROM no longer enforce the region lock?

Check out this rom: http://forum.xda-developers.com/showthread.php?t=2487425
It is region free but it's a N9005 custom rom and it works fine with a N900T Note 3
phone. The only thing which it will lack is wifi calling.
After flashing the rom you will need to flash the wifi/nfc/bluetooth fix in recovery
in order to get the wifi working. (not wifi calling!)
Here is the link to the wifi/nfc/bluetooth fix zip file: https://dl.dropboxusercontent.com/u/45687485/Needed_Files_BT_WIFI_NFC_Flashable.zip
Good luck!

Same results with this ROM Boots to a "Enter SIM unlock key", and "Network locked SIM inserted" screen.
I don't understand - as my understanding was the region-lock was only for the INITIAL activation of the phone in it's home market, IE it was activated at some point in the US with a US sim!?
It would figure now that it has been rooted/ROM replaced it wouldn't region lock again?
The phone did have a black-listed IMEI - but worked on roaming here with my US sim prior to porting the number to Google Voice smh

region free and sim lock are 2 different things.
sounds like you need the sim unlock code
I used freeunlocks.com,you have to do a trialpay thing but there may be one that suits your needs?
cost me just under £5 and I got 4 unlock codes,network,provider,sub-provider and defreeze.
my phone is now sim unlocked and sim unlock also does region lock

Hi,
I had the same problem with my European Note 3 when going in Israel.
The solution was to unlock the phone by using a European sim and calling somebody (for instance your voicemail) for 5 minutes or more.
Then it was unlocked...
Try it if you have an American Sim somewhere...
Hope it will help...

Thank you, I'll give it a shot.
I went to a Samsung Service Center (in Hong Kong), and they told me I would have to get my "American Carrier" to unlock the phone and that they could not help me.
As I am not a customer of T-Mobile USA anymore I don't think there is much I can do- as I don't think they will help me over the phone or would have any idea what to do at a normal T-Mobile USA store.
I might try to find an American Pre-paid SIM and try that option.
I recently purchased a Galaxy S4 i9505 on EE from Carphone Warehouse, and flashed the 5.0.1 BTU firmware. After I did that I then read I'd need to be carrier unlocked, but I tried calling and receiving calls and messages and using 4g and it worked fine. I also saw some posts about flashing modems. Anyway I'm really confused about what I need to do; should I try and unlock or not. Thanks everyone for your help.
The BTU firmware has no carrier branding, which means it has no carrier logos or bloatware included in it. Other than the lack of carrier doodads, it's the same firmware. You shouldn't need to flash a modem as you already have the latest, from when you installed the BTU ROM. However, the S4 would need to be unlocked for use on any carrier if your SIM isn't an EE SIM. But, you either have an EE SIM, in which case you don't need to worry about it, or the S4 was unlocked by the store that sold it, in which case you don't need to worry about it.
TL;DR: Don't touch the ROM. Don't worry too much about the SIM because you can make calls and use data. You don't need to flash a modem.
Hello guys. This is my first Samsung device. It's network locked here in the Philippines and I flashed UK firmware to get Nougat update. Since thre is an official update available now in our country, I flashed the firmware downloaded from sammobile with CSC SMA (philippines Smart). The problem is, SIM 2 is not working for a different SIM card (ex. Globe). Does anyone know how to fix this issue? Before only SIM 1 is Network locked and SIM 2 is openline. Now they are both Network locked.

As far as I know, Dual SIM phone has issues when trying to unlock the phone. they are problematic and sometimes they refuse to work. I recommend you take it to Samsung assistance, maybe they can do something with your firmware and make the phone work again.
Hi. Recently i bought an S10+ and what i heard from the buyer is that the S10+ was locked on EE UK. (And after, he unlocked it)
I'm stuck on May update (SE7 EVR) so i was thinking to change the ROM to POL(Poland) for example.
It will be locked again on EE UK if i flash with Odin and change the ROM?
After the network sim unlock phone is unlocked no matter the rom.

Thanks for the reply. I'm getting an error when i try to update: " Your current software isn't supported. Please visit a repair center"
I'm stuck on May Update. I'm thinking to switch the ROM.
Im coming from a S9+. Its been two years since i played around with flashing Fw etc so my memory is a bit hazy.
Short question. If were to put a USA sim card in my Canadian S20+. Will that cause a factory reset? Or does the canadian fw does not have the CSC files for the US carriers so it should continue to function as is, but potentially with missing features for the US carrier? Does that sound about right?
Thank you
It will work just fine, if the device is carrier unlocked. I have an unlocked G981W from Bell, and an ATT sim worked no problem. No device reset etc required.
Also have tried a Rogers and a SaskTel sim without issues .
Cool thanks.
