CSC has nothing to do with the carrier lock. The lock must be removed by the original carrier and can only be done by the account owner.

I just entered the unlock code I received from ATT and got the message unlock code passed. I take it that this means its unlocked? Is it a permanent unlock?

I believe that it is a permanent unlock - however - please read the WIKI and do not confuse UNLOCK with HARDSPL if you are going to FLASH ROMS.

what was the exact code or numbers you used to unlock the phone...because some of the #'s for unlock just unlock the service providers branded lock but the other codes unlock the phone period
if the code is from AT&T, then its for permanent sim unlock and you can use other sims. no more, no less
Yes the code is directly from ATT. I told them I'd be doing some international travel and wanted the option of putting in a european sim card while there.
does the RUU effect the simlock

What is Sim lock?
In order that carriers can insure that you stay with them have imposed a sim lock on the deivice that they have sold you. You are thus unable to use any other SIM from any other carrier. The only way to overcome this is through a sim unlock tool that is available via the internet. Flashing a different rom version or a different language will not change the SIM lock status.
Hope this helps
I bought a used Sprint M8 Not HK version
And I successfully unlocked the simlock,because I have been to China and I can use the GSM and CDMA network there.
I want to change my carrier as AT&T or T-mobile even if Version Wireless,but it just tell me the SIM Card Is Invalid !
I visited a lot of website and tried any possible solution on the Internet,include but not limite in: Change ROM,Flash Radio,Format /cache /sytem /data,Retry simlock again and again,Set QPST,Set CDMAworkstation,Set DFS ...
Well,
I even want to buy the unlock code from xxxxxx.com,but they warn me do not buy the code if the phone didn't request.
Why the phone didn't request the unlock code?
I truly hope I can unlock this phone,
If you know how to deal with it,Please help me!
I am using Sprint (maybe)original ROM,Software version 3.31.654.2,OS vision Android 4.4.4,Baseband version 1.08.20.0916
Even if you SIM unlock the phone you can't use it on another domestic carrier. If you're international that's another story.

But it is designed can enter the unlock code to unlock domestic carrier and international carrier.
And the domestic unlock code is actually exist,just have no idea why this phone not ask.
Maybe the unlock program damage the part of domestic unlock function?
Hello everybody I have question about friends mobile. He bought it in USA from T-Mobile but now live in Europe. I think that there are 2 ways how to solve SIM lock right? First one: use some reliable but cheap service for unlocking by code. Second one: flash Android to global version? Can you tell me if it possible to flash N960U to some no SIM blocking Android? I flash some years ago some Samsung phones with ODIN, dont know if this can be used on phone sold in US.
I tried this https://forum.xda-developers.com/galaxy-note-9/how-to/n960u-tmb-stock-odin-files-firmware-t3833205 but it keep asks me for unlock network code
Thank you for any advices...

maybe try n960u1 firmware instead of the regular U. use patched odin 3.13.1b to flash it.( and flash all 4 files not just the AP.md5....)
also I belive that it might be region locked. usualy to lift that a 5 min call should have been made on US soil with proper carrier sim. if he never used it on us soil then that might have been the issue.

A N960U1 rom might work. use the CCT csc for it to be completely carrier less. thats the "Unknown" variant as opposed to XAA which is USA unlocked.
use this to download the file faster than the freemium download speed on sammobile

XAA and CCT have the same files, so does all other firmware under the XAA multi csc

they have the same files but depending on the csc it will load different configs for each. using CCT is the unknown variant so it should ask the sim card what region its in and hopefully sim unlock it.

the firmware file you dl is all the same regardless.
now on the device if you can manualy set the proper CSC code then yes that should work as you mentioned. but if nothing is modified, then system will just pick the appropriate or last csc that was set in root/efs/imei/mps code.dat
there is an other thread in the forums that has a procedure to force csc code for non rooted devices. it involves adb and flashing combo firmware if I'm not mistaken.

that very well may be the case. but at least before calling it quits might as well explore all available avenues.
Hi I find a 2nd hand pixel 4xl from 2nd hand seller and the device status looks good for me, but it's strange that the oemlock could not open but the imei number checking from google repair is unlock , even not related to some carrier
any one know something about this status?

You likely have a Verizon model and their bootloaders can't be unlocked. The IMEI check likely refers to it being carrier unlocked, not bootloader unlocked.

Thanks for your reply! You mean that the unlock status is update if simlock from carrier is unlocked(like sending unlock request to att , if success the google repair query will also update)?

OEM unlocking toggle in developer options refers to the bootloader unlocking, not carrier unlocking. They are 2 different things. If your OEM unlocking toggle is grayed out in the disabled position you won't be able to unlock the bootloader to modify your device, such as flashing roms, kernels, etc...
If you have a Verizon model you won't be able to unlock the bootloader. I think maybe with T-Mobile if you can get the sim unlocked you will be able to unlock the bootloader. Not sure about other carriers.
Also, you should delete that picture. If that is your real IMEI number you don't want other people to see it.
