Alright I used my phone to test the briefcase. It is running Android 4.1. It took a few folders for it to happen but I did get "Error Unable to Open Connection to Server" I was trying to access a briefcase share. The share has a few folder under it and I was able to browse to a few of them then this one gave me trouble. I copied and pasted Just the part before and including the error in the log. I have the whole thing saved as well.
