Only way you can unlock is is paying and going to this thread. There are no programs that you can find or use to unlock your phone unless you call T-Mobile and ask them to unlock it for you for free, then you will have to pay. Its a small amount anyways but go here for more information.

Possible Unlock For SGH-T999L?

After scouring the net for the last week or so to find a method of unlocking the SGH-T999L without either purchasing a box or an unlock code from a shady eBay dealer, I stumbled across an app that seems like I might do the job.
RegionLockAway by Chainfire seems to remove the network lock on this specific model, despite being designed for the Galaxy Note 3.
(original thread) http://forum.xda-developers.com/showthread.php?t=2470551
Now, I've tried this on my phone, and as I said before, it seems to have removed the network lock on my SGH-T999L, but only partially. I am no longer bothered for an unlock code when booting the phone with an AT&T or MetroPCS SIM card inserted, and my account details assigned to the SIM cards are displayed under my phone's settings. The issue is that I cannot seem to connect to any networks.
I don't know if this will lead to anything, but I just felt like sharing this little tidbit of information with you guys. If anyone else would like to try this out and post results, I'm sure it would be greatly appreciated by the community. Hopefully this gets us one step closer to unlocking this bastard of a phone with minimal effort.
P.S. If this is in the wrong section, feel free to move it, and I apologize.

Rooted sgh-t999L with stock 4.3... I just tried this in hopes of a network unlock as a side effect and it did not work. I ran it twice to make sure.

IS there anyway to downgrade boot loader note 10 plus n975f

Is there any way to downgrade bootloader note 10 plus n975f, I have installed one UI 2.1 latest august security patch with N975FXXU6CTGD bootloader, Problem is My mobile is demo unit and someone installed patch with IMEI match in it and it was working fine until I did a mistake of upgrading. now its apparently not possible to downgrade or get back mobile networks back. Is there any solution to my problem. IMEI showing fine and when I check status by #*1234# and its showing status NG. I want to get come back the call option to make calls please help me if there any solutions. I have tried chimera and it says unsupported modem try to install different firmware.

All the stuff you mention sounds really shady, as all demo units are not to be used as regular ones, in other words, the demo units are issued to carriers and official distributors, and never intended to be sold to public, thence, having one is not normal, no help will be offered here, as it is illegal in most countries to tamper IMEI numbers, which is a common practice with stolen and red flagged devices, next time gather enough money to buy a legal device

@ farhan_ali790 - Some things you have been saying within regards to this phone are quite unsettling. Either your mistaking what phone you really have, a communication/detail issue, or you got the phone second hand and this is the way it was when you got it.
Either way the following will be of interest:
If you have a demo phone then it should not work on the cellular network. Those are for demonstration purposes so people can see what the phone looks like, see how the screen looks and get a chance to use the apps on it. For this reason the phone was made in such a way that the ability to connect to the cellular network will not work. If you truly and really do have a demo phone then it will not be able to access the cell network.
If your claim is you have a demo phone and that it is showing (or had the IMEI number changed/patched to show) as a N975F and your talking about a patched IMEI number then sorry, but your most likely out of luck here. The discussions of tampering or altering an IMEI number are not allowed due to such actions being illegal in a lot of places. Contact the person whom patched the IMEI for you for help on this one.
It has been mentioned numerous times that flashing a bootloader higher then what is currently on the phone is a one way street. You can not downgrade the bootloader. Please take the time to do some research on the subject if you have further questions on it.

Question [CLOSED] IMEI changing

My phone's IMEI is changed without root and I'm on Android 11 rn. In my country you have to pay a heavy tax to use imported phones so I replaced my phone's IMEI with another phone IMEI which is already registered with government.Now I can use phone with sim normally.But what if I update to android 12 then will my IMEI be reset to original IMEI of my phone because if that happens I won't be able to use sim without paying tax that's actually more then the price of phone.
I got OnePlus 9 pro and I'm in Pakistan and IMEI is changed with a s7 edge whose tax was already paid.

@Sarmad00 Thread closed!
Edit or change of IMEI is illegal in quite a few of countries. For this reason, I've closed and edited your thread! XDA doesn't allow and doesn't accept discussions about or support for such an edit or change.

If the phone is showing that message and was purchased off of eBay, then the phone was stolen from a business. The phone cannot be utilized as it will be flagged and will have its IMEI blacklisted after some time. That message you are seeing confirms that.
Unfortunately for you, there is no work around to resolve this - as theft isn't a 'real' phone problem. The protection with phone management is just a corporate move to give companies more control over the devices that they purchase. So essentially, there is a much lower chance of them being stolen. Because once they are stolen, they're basically just local music players that cannot be utilized as a cellphone and will automatically wipe themselves clean on a timely basis (once they are reported as being stolen).

Thanks vor your reply,
i don´t think the phones was stolen because the selers of this phones is a company in Germany and they have more than 50 pieces of this phones, They wrote on the listing that the phones was used only for demostration purposes , so google will not remove the mdm lock if i contact them on the geving email adress?

If the device is truly legally sold, you need to get into contact with the seller to see if they can release it from their MDM server. If they cannot, only they can be the ones to contact Google. Google will NOT help you if you do not have the original purchase order from when it was MDM enrolled. Even if the user has a ton of devices for sale, that doesn't mean they were acquired legitimately. It's possible they were supposed to be destroyed and kept enrolled to prevent them from being resold, which is what sounds most likely to me. As someone who works in IT asset management, the ONLY reason we leave our devices DEP or MDM enrolled is to prevent someone from snagging it before we dispose of it.
