God help me

Hello, I still have a problem with Arduino ATmega8U2 bootloader, so I am trying to re-flash it using the 8U2's ICSP interface, but this happened: http://imageshack.us/photo/my-images/841/sckerror.jpg/ I use AVR Pocket Programmer and avrdude 5.11. I think a problem is in 8U2 fuse settings but I dont know how to set it up. Any help will be appreciate.

Instructions are here: http://arduino.cc/en/Hacking/DFUProgramming8U2

Yes, but it is updating of working Arduino. I need to re-flash it. No matter what I do a SCK error is alway appear...

Have you got a working clock?

Was this a working board before?

Yes, 16MHz crystal should be ok. Arduino was working fine until I accidentally unplug USB cabel while I was uploading new program into it. I think I damaged bootloaders of both chips. It looks like I am able to upload program in to 328 using its ICSP inteface, but I cant upload something in to 8U2. 8U2s ICSP interface should be connect correctly (LED lights, Arduino is powered), but the SCK error alway appear during programing. Even when I am trying to set up fuse bits somehow.

P.S.1: There is some solder pads at back of Arduino, near the map of Italy and USB connector... P.S.2: Thanks for reply. P.S.3: Sorry for my english...
