How to Enter Unlock Codes on a Cingular BlackJack
Step Action
1 Insert NON Cingular SIM into device
2 Power on the device
- Wait approximately 30 seconds until the SimLock application appears (the delay may be longer if the user has already attempted an unlock with the wrong code)
3 Enter the unlock code in the blank field
4 Press Ok
- If the unlock code is incorrect, an error dialog will appear. After pressing Ok on this dialog, the user has to re-enter the unlock code after delays (see above in Device Specific Information)
- If the unlock code is correct, a success dialog will appear.
5 Press Ok
- The device is now unlocked and should continue booting
OR
Insert disallowed simcard (a simcard that the phone does not usaully accept) and enter unlock codes when prompted
NOTE: If you are unable to connect to service provider or unable to make out going calls or recieve messages, this has nothing to do with your phone being locked or not, you need to force the BlackJack to change to GSM mode, this can be done as follows:
Power on your Phone
Enter *#1546792*#
Select Option 3 Network & Call Settings
Select option 5 Network Mode
Select GSM
This should resolve your problem.
