I am one of the people that bought two of the TP's from store and they turned out to be Demo tablets. I once before was able to activate mine and my wife's tablet with impostah. But because I messed up the 3.0.5 update i had to doctor it, now I cannot finish the activation. I was able to use Dr. Skip First Use to get past the login, but I cannot get impostah to activate it for me. I have follow the instructions I found here, and even tried the Device Profile Override. I also have doctor it to the previous versions, and gone into my HP webos account and deleted the backup, to see if that would help but I am having no such luck.
I am really hoping someone can help.
