Welcome to the AndroidForums, Underpants
I'm betting the good folks in the Orange SF all-things-root sub-forum can help guide you with your problem:
San Francisco - All Things Root - Android Forums
They'll know best about your issues and may have a solution for you.
Also, here's a link to your device's home forum, too:
Orange San Francisco (ZTE Blade) - Android Forums
Best of luck and again, welcome to AF.
