I know how frustrating this was and i got it done by myself by experimenting since everything cant be googled that easily. i figured i can help anyone out. this has worked for 5 phones that i have done my self so 5 for 5 YESS!!! This is as satisfiying to me as watching micheal jordans final shot! 
any ? contact me at [email protected] 
ok i figured it out. for all those people that have gotten the dreaded phone freeze om samsung propel a767 or any other samsung phone so far not sure about touch screen. 
first look for a local unlocker in ur area or somewher that can provide the codes and get the unlock code and phone freeze code. mine was only 20 for both and took less than 24 to retrieve. email me for his info. 
insert sim that you want to use (tmobile). you get the screen which says phone freeze. type in the freeze unlock code which was given and the press the att logo/menu button.  
**YOU WILL NOT BE ABLE TO SEE THE NUMBERS YOU ARE TYPING SO KEEP TRACK OF WHAT YOU INPUT** 
after you have entered number and pressed button then you will get a network lock screen. this is where you type in ur unlock code. type that in press confirm and BAMM!!!! you are now able to use tmobile sim
