Unzipping IPSW failed

It seems that there is a problem happend while Sea0npass 0.7.6 extraction process “Unzipping IPSW…”. This dialog runs endless and only killing the Seas0npass process will help. I’ve tried to extract ~/Documents/Thether/AppleTV2,1_4.3_8F305_Restore.ipsw by my own using Mac OS X extraction utility which resuts in an error. Also the unzip command line tool failed to extract. Removing downloaded file, a reboot and a new download try doesn’t help. I seems that the downloaded ipsw file is broken. Can anyone check, if this file can be extracted after download?

 

sorry… the problem was already posted.
