T-Mobile Galaxy SIII LTE Edition SGH-T999L Network Locked !

Hello guys !
I have this phone T-Mobile Galaxy SIII LTE Edition SGH-T999L.
My phone is Network Locked. I did couple of things to it..like tried
the free unlocking method...by *#197328640# method...going to the ServiceMode..and all that...but no chance
Also tried flashing the T999 Modem on my T999L....but then i was getting No Connectivity+IMEI "unknown"+ "ServiceMode was Blank".
I was adviced not to flash the T999 Rom on T999L as it will brick my phone. So i sticked to the Advice and didnt flashed it.
But i need to unlock it as soon as possible...So i was searching for it...and i have seen couple of ways to unlock...like...
there are some sites who provide unlock codes or unlock softwares like this one :
http://www.fastgsm.com/en/samsung/t9...code/unlocking
Do u think i can use it to unlock my phone..by paying...?
Or someone else knows a good place to purchase the code from ?
Thanks in Advance :good: .

[Q] Galaxy S3 - Will debrand ruin unlock?

Hi all,
I've had a bit of a read about on the forum but can't find a definitive answer which assures me enough to go ahead.
I've got a samsung galaxy s3 i9300 which was locked to o2 and currently on 4.1.2
I purchased an unlock code which has unlocked the phone successfully.
The phone is branded o2 which I am wanting to de-brand, having a read around it seems i need to flash the stock 4.3 BTU rom which I have downloaded from sammobile.
Question is, if i flash the BTU rom to the phone, will it cancel my previous unlock?
Any help or confirmation would be greatly appreciated, thankyou

Unlocking T-Mobile Samsung Galaxy S3 Rooted with LiquidSmooth 3.0 PLZ HELP!!

Hi I am new to the site and am hoping to get some help. I have a Samsung Galaxy S3 T999 from T-Mobile which has been rooted with Liquid Smooth 3.0. I have AT&TT and have been trying for over 3 days to unlock this phone with no luck. I even got a network unlock code from T-Mobile but it won't work. I was told it was because it is already rooted. So is there a way to unlock my GS3 without removing the root and returning to stock to unlock then having to reroot it?? Thanks in advance!
