in the process of upgrading my storm to .76 i needed to backup the device before wiping. for some reason it keeps on getting held up at the "backing up device memory" phase of the process.
In another thread, someone suggested going into the advanced backup and running the backup manually. I did that, and it allowed me to isolate the problem file. It is my browser cache. It didn't solve my problem, but at least I know the source. I also know that all the rest has been backed up.
