Please help! Unlocking K800i. Shows 'Insert Correct Sim'

[Zegs]

Hi people, I need urgent help on unlocking the K800i Sim. I tried all the ways, I tried using K810's firmware too but the same error 'Insert Correct Sim'. It is my dad's phone and if he gets to know I'll be in trouble. I've been sitting on the computer for about 8 hours trying to figure this out, didn't even sleep last night. I'm totally confused, please help.

My K800i : CID52

Please please please help me! :'(
