Thank you I've managed to successfully root my samsung homesync.
The only thing that I wish I could fix is the homesync app on my samsung s5.
Since performing a factory reset on my samsung s5 the homesync app has been unable to find my device. This was not a result of the root but was happening prior.
I've noted that the app has additional permissions that don't seem to stay on when I've turned them on.
I've managed to install a third party remote droidmote in the meantime but I would prefer to use the homesync app.
If anyone can assist that would be greatly appreciated.
