UNLOCK MOTOROLA SYNC

DO NOT TRY MORE THAN TWICE ... u can only do 3 attempts .. if the third don't work u will freeze your phone





Unlocking the Sync Instructions
The idea is that you are changing your phone's 8-digit unlock code to all zero's.

(1)Turn off your phone and remove the sim card.
(2)Then power the phone back on.
(3)Enter the following numbers on the keypad: *2767*3855# this will restart your phone,
(4)When your phone has restarted and powered back on you will enter the following into the keypad *7465625*638*00000000*00000000# If your phone says wrong password, turn your phone off and put in an unaccepted Sim Card into the phone (A sim card from another Service Provider) and then start the process over again. If it says wrong password even with the wrong Sim card, then you have reached your second attempt, Do NOT try it again. Instead, go to Ebay and purchase an unlock code.
(5)NEXT ENTER #7465625*638*00000000#
(6)AND THEN *#7465625# to check the locks....all locks should now be inactive or Off
If you find that some of your locks are still turned on, now that you know your phone's unlock code, (00000000) you can use the following codes to unlock individual locks on your phone (Where you see the word Code you will put in your new unlock code, which is now 00000000:
#7465625*638*Code# = Disables Network lock
#7465625*782*Code# = Disables Subset lock
#7465625*77*Code# = Disables SP lock
#7465625*27*Code# = Disables CP lock
#7465625*746*Code# = Disables SIM lock
#7465625*228# = Activa lock OFF

FOR PEOPLE WITH PHONE FREEZE ON SAMSUNG- the #7465625*638*code# is not needed when you have the phone freeze just follow below.  
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
