I have a Samsung Stratosphere running Gingerbread 2.3.5, rooted. Recently I tried to use the Backup Assistant app and it gave me the error message: Service Failed Sync state not supported by this operation How do I get it to work again? I can't think of anything that could have caused this. It worked when I first got the phone. And please don't just say that google's backup is better Most of my contacts are saved on my phone and not the gmail account.
