I tried to root my 55HU8500 yesterday evening - realistically I should have done without being sleepy like hell I think, but here are the results which I can't really understand:
It took some time and a reboot for SmartHub to detect the app on the USB stick
First try, I started while using LAN for some reason (tiredness):

So I switched to WLAN and ran again:

generated were the qca-file, vendor and network type info but no version magic
Script output:
cat: ./vermagic.txt: Datei oder Verzeichnis nicht gefunden

What I wondered about is that the widget did not ask specifically to reboot the tv. Nevertheless the files were created.
But no port 21/22/23 open
