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
