I am having the exact same issue as tdavis74... point for point, item for item.
I also have the K2i. The K2i jailbreak software loaded as outlined, however, when I went to install the screensaver software, I also received the U007 error.
I attempted to uninstall both screensaver and jailbreak software using correctly designated uninstall software, same fail -- same error.
Ideas? Suggestions?
Thanks!
