wifishield downgrade problem

Hi everyone,
I use wifishield on Arduino uno Rev.3 board and got a problem when I downgrade the firmware to 1.0.2.

I follow the firmware update guide
http://arduino.cc/en/Hacking/WiFiShieldFirmwareUpgrading

to downgrade my wifishield.

after I type the command, my wifishield crash.
batchisp.exe -device AT32UC3A1256 -hardware usb -operation erase f memory flash blankcheck loadbuffer /Arduino/hardware/arduino/firmware/wifishield/binary/wifi_dnld.elf program verify start reset 0

the error LED keep lighting and cannot be detect by PC or Arduino Uno

I’ve try to make jumper between pins 7 and 3, but still not works.

Is this mean I killed my wifishield?
How can I fix it?

thanks
