i9020 Nexus S - I can't unlock bootloader - BRICKED

Hello!

I have a big problem with i9020.

I bought a defective - stay on "google" logo.

When i go to fastboot (vol up + power) ist all ok.

Bootloader is locked -> i go to CMD and adb folder.

Fastboot found my devices, and i put "fastboot oem unlock". On device
received the message with question: "Unlock bootloader?"

I go to YES and click POWER.

now phone is freeze...

you have any ideas?

sorry for my english
