Wow, sounds like a very irritating issue.
I got everything working for me first time, and I don't understand why so many are having issues at the end of the install process. Everything should be fine if you've made it that far into the install.
Also, it's been mentioned before, but any console with a 256mb nand, which is most phats, will not be able to use these tools. Don't bother. Can a mod add this to the first page seeing as George234 hasn't been active here recently?
