Hello Noob. One of the convenient way to do so is to manually delete the folder. 1°) If you don't have it yet, install this application : http://maemo.org/downloads/product/Maemo5/rootsh/ 2°) You need then to open a terminal. Either you find it in the app menu, either you use the shortcut sym/ctrl-shift-x You see at the end of the bootom line a'$' sign : it means you have a simple user access to the N900. I guess the user privilege aren't enough to be able to delete the folder you want. So you want to become root. 3°) you become root either by taping the command sudo gainroot or simply root New lines are written to the screen and you can see now the sign "#" at the end of the last one. It means you're root, ie God of the N900. Keep in mind you have now the power of destruction on your system, so be extra careful, specially as you are going to use the rm command. 4°) Simply type rm -rf /var/lib/bluetooth/<macaddr>, where <macaddr> is replaced by your own mac adress. At this point you may not have a single clue about the name of that folder as you may not know what your Mac Adress is. So a trick is to type only rm -rf /var/lib/bluetooth/ and then stop typing. Then hit the Tab button at the bottom of the screen (do that once or twice). It should print all the folders and files listed in "bluetooth". The one named with your Mac address is like XX:XX:XX:XX:XX:XX, so you can't really miss it. Underneath you'll find the line you just typed before, waiting to be completed with the name of the folder you want to delete (be extracareful not to hit enter at that moment as you would destroy the whole bluetooth folder). Just start typing one or two letters of the <macadr> folder (respect the case). Hit "Tab" button again : it should auto complete the name folder, saving you time and errors in typing the whole name. Now you can hit the enter key to delete the folder. And close the term application. Please note I don't take any responsability if you brake your system by following this guide. Besides I don't know either if this process will solve your bluetooth problem (But I hope for you it works).
