ok If you hav'nt guessed - I'm keen to get this working :-) update to above is as follows. I thought I would try these steps again in case I got it wrong. firstly I sudo gainroot then... 1) cd home/user/MyDocs 2) tar xvf tether.tar 3) three files produced. 4) cp tether-dbus-config /etc/dbus-scripts.d 5) cp tether-dbus-controller.sh tether.sh /opt/tether 6) reboot 7) Par n900 and Nexus 7 8) select "use this connection for internet" in Nexus 7 bluetooth settings 9) run script: ./tether.sh start 10) message shows "Tethering from bnep0 to gprs0 activated" 11) Try to access web on Nexus... 12) no internet connection Help me save my N900 for a bit longer :-) think of it like rescuing a puppy.
