Only thing you can do is do a factory restore. Do a wipe then reinstall the OS. But as far s getting it back to how it was before the restore, I don't think that's possible without a backup of what that was.
You would probably get a better response in the Curve forums.
I don't know, the process is basically the same on all models. Not sure why you'd chose the Bold forum for this over either your own model's forum or the general forums, but the answers he gets here will be no better or worse for it.
