ok, for easy sake...

prerequisites: must have wget and become root installed.

if you don't, please go to your application manager and delete all your repositories. then open this on your n810: http://download.dailydffr.net/linux/...05-08).install

then in the application manager go ahead and install becomeroot and wget.

Next download these to your INTERNAL MEMORY CARD:
http://download.dailydffr.net/linux/...p/root.install
http://download.dailydffr.net/linux/...p/user.install

now open X terminal and run the following:
this will download and install a set of needed applications, it will then create a backup directory and backup your existing system bluetooth config files. Finally it will download some files I have personally successfully tested 5 times.

once that completes go ahead and reboot.

once it is back up, open X terminal again and this time as the NORMAL USER run this:
this will create the needed a2dp configuration files in the user directory.

Finally you need to open and edit the ~/.a2dprc file. look for the line:
change it to this:
make sure you enter the MAC address for YOUR headset in there else it wont work.

Last thing, you need to pair your headset to the n810 via the usual method (open your control pannel, open the bluetooth applet, enable bluetooth, so on... for more on this, use google, I'm too lazy to really go into it.)

and after you do all that, reboot.

once it comes back up, kagu can now pair your BT headset w/o any further muss. for usage of kagu beyond this howto... again, that's what google is for.
