Press the right softkey. (just keep pushing the down key to get a menu) 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.
