Put a Non-acepted sim card in the phone
Start entering unlock codes as they are written above,
after typing first code you should have a message like "Done" or "SIM MEP Failed"
Go on entering the codes, and see the phone boots up after entering some codes (gennerally it needs 12 and 32 codes)
If you have message "Wrong Password" after entering unlock/lock codes, then use Reset/Repair codes,
Then type unlock codses
So your phone is unlocked !
