    I accidentally turned my phone off when it was locked. It wasn't any complicated one, just a regular password. So my phone turned off and I can't get back in. I tried everything: I took out my card and put in a T-Mobile one. Nothing came up except the password screen again. That didn't help. I tried to leave the card slot empty and type in the code everyone's been posting. I went to Malloc Fail and the phone sort of reset. I don't know what happened. Then it asked me to put in my SIM card again. I did and it just kept asking for a password.

  1. If you have changed your phone password, change your password back to the default 8 zeros (00000000).
    NOTE (Modification here by my experience): Go to SETTINGS, SECURITY, then SIM LOCK and disable this before proceeding.

  2. Put a SIM card that is from a network other than the one your phone is locked to.

  3. When Incorrect SIM error comes up, input *#9998*3323#.

  4. White screen will appear with an exit option. Press the right softkey.

  5. From the menu that appears, select the Malloc Fail option. This will reboot the phone and the normal service screens will appear.

  6. Type *0141# and then press the green call key. "Personalization" or "Personalized" will appear.

  7. Turn off your phone and put the original SIM back in.

  8. Turn on your phone. You will receive a prompt to enter a password.

  9. Type 8 zeros (00000000) (This is because the SIM LOCK Mentioned earlier gets switched back on)

  10. Completed. You have now unlocked your phone.

    You now have an UNLOCKED Samsung D807

  11. With the studio software from samsung you are able to edit and move contacts from your phone to the sim and back. Or copy from the phone and put them on the sim card.
