This might be a stupid question but I want to ask anyway. I just bought a T-Mobile Note 2 and am awaiting a sim unlock code (I know I can downgrade to 4.1.1 and unlock it via the hidden call menu but at this time I am not opting to do that). I flashed the 4.1.2 Root Injected Stock Rom. My question is, (which maybe I should have asked before hand) Will I be able to use the sim unlock code that T-Mobile provides me with despite being on the root injected 4.1.2 stock rom? Thanks!
No issues, I did it and it worked for me.

I unlocked it using the code provided by t-mobile.

Hey guys, just a heads up, if you are running 4.1.2 there is NO WAY to unlock your T-Mobile Note 2 without downgrading to 4.1.1 as far as I can tell. Even if you receive an official code from T-Mobile it will not work because when Samsung patched the security hole in 4.1.1 which allowed people to unlock their device manually they (accidentally) blocked any way of sim network unlocking. You can read all the complaints on the t-mobile website forums. So, with that being said you have to downgrade to 4.1.1 with Odin and access the hidden menu from the dialer. Just search the threads and you will find easy instructions.
NOTE: When you downgrade to 4.1.1 make sure you do a factory reset from recovery before you flash via Odin. After you flash the ROM your phone MIGHT go into a bootloop/hang on Samsung logo. Just go back into recovery and factory reset again. Give your phone about 4-5 minutes to boot up, just sit it on the table.
YMMV.
Thanks a lot for the tips but I downgraded before and it didn't work.
I still have a backup of the rooted 4.1.1 stock ROM. That's how I downgraded and tried to unlock but nothing happened.
Do u think I did something wrong or is there another way?

Ok thanks how do I reflash the att stock image if I wanted that
Sent from my R800at using XDA App
once you have the bootloader unlocked and clockwork recovery installed you can make a complete backup of your phone in the recovery mode.
Thats what i did before i flashed a new rom. The stock att rom is not available here so you need to make a backup as far as i know
And ok I dnot want to unlock so I was going to go the route of flashing the other region firmware. But if I dint have the stock att firmware to go back to I dint want to do that. Guess I will have to wait to see if someone can figure out root without unlock. Thanks for the help though I understand now.

I had att but flashed to r800a 2.3.2 using wontanserver.com (its free just got to register) then used gingerbreak and updated OTA to 2.3.3 with bootloader locked. R800a is like att but no att bloatware.

Right but if you ever wanted to go back to r800at stock firmware is there a way?
Sent from my R800at using XDA App
I was wondering this myself, since I too have an AT&T play, running the 800a firmware on GB. I've been having some issues with it though. Is it possible to go back to AT&T stock?
No unless you unlock bootloader and find someone who made a back up of the att rom.
What problems are you having?

So i talked with T-Mobile couple days ago and asked them for a Unlocking Code for my T989 and i just got it today, I restarted the phone using a Different SimCard and it doesn't prompt me for Unlocking the Device this could be cause of the Rom i have currently installed which is the XTREMEPERIA#5, Is there any Rom out there i could use to Unlock my Device without Restoring it to Stock Version using this Guide

You just need to use stock to unlock than your device will be permanently unlocked.You can use any roms after that

you will need to be more specific, im sure it does not says "its modified!" on those words, a screenshot would be nice.
Assuming it says that on "About phone" is not rooted already?
Depending on the method used when it was unlocked it may be locked back, I have not seen a software unlock, so far all the unlocks for the note 2 have been by code, or by Samsung Dev Menu, in those cases they are likely to stay after rooting your phone. Proceed to root your phone at your own risk, but more likely it wont be locked.

Download 'root checker' from play store..if no root access.Do a factory reset.
Just checked with root checker and i have no root! But it still says my device is "Modified" do you think the device will still be unlocked if i do a factory reset ?
Sent from my GT-N7100 using xda app-developers app
Yes you can wipe
reboot to recovery, wipe cache and data (factory reset)
reboot normally and play for about 10 min before checking status again
If it is stil modified, just flash stock ROM with PC odin (find on 1st link on my signature)
On a T-mobile note 2 Model # SGH-T889 will a factory reset change the unlock status if the phone was unlocked by T-mobile?
Not that I'm going to try it because im happy on 4.1.2 rooted , but I was just curious to find out if this is true if I update to 4.3 will lock the bootloader basically putting me in an AT&T situation

It won't necessarily "lock" it, but it'll restrict you from downgrading firmwares.
Is there anyway to Unlock the Samsung Galaxy S3 T999 with Android Version 4.3 , I tried everything , Downgrade Firmware , Change Modem to UVLJC and nothing . Help please
Flash a 4.1.1 or 4.0.4 ROM and modem (not Odin, or you will brick), then follow the unlock guide.
Alternately if you have the phone thru T-Mobile they will unlock it for you if the bill is current, or you can buy an unlock code online for under $10.

It doesnt work that way either. It lose the imei with a different MODEM, you need to flash it again the New Modem to recover the IMEI. Please I need to unlock this device. Any ideas?
Where 4.3 is concerned, there is no way to unlock using any of the previous methods. Your best bet is to call T-Mo
Im having problems sim unlocking as well. T mobile sent me a code that does not work. Still waiting on there help. Suggestions?

Well after calling TMobile again and spending close to an hour on the phone they escalated me to "Someone Will Call You Back" LOL
So Today I downloaded the stock 4.1.1 and loaded with odin. Then Used the steps in the below thread to obtain sim unlock without TMobiles help.

sim unlock 4.3
You only have two options... Option 1, You wait until kikkat 4.4 become available for upgrade then unlock the phone with same code. Or option 2, you find the stock rom that came with the the phone which is the ice cream 4.04. Then use odin to downgrade and then you can use the same code.
