YouTube No Connection Touch to retry
Just for possible information.
I have KFHDX 7 rooted, with the setup as described by Cpasjuste (for which many thanks) using gapps-jb-20130812-signed.zip. However, I could not get the latest update of YouTube to work. I always got the message "No Connection, Touch to Retry. Eventually I discovered it was because I had Android Firewall installed and had not set Media Server. Now YouTube works with no problem. ( also had all the Google services set but do not know if these would have affected the problem had they not been set.)
