Notices

Sorry if I am duplicating but after searching for several hours I cant find similar issue or solution.
All of a sudden the n900 has lost all bluetooth functionality. When I go to turn it on the device name has disappeared, and if it is turned on and visible, selecting the save option does nothing. Loading a file and attempting to transfer via bluetooth also produces no response at all. I have installed nothing for some considerable time and do not have anything similar to Autodisconnect installed.
Does anybody know of a cure or possible solution other than reflashing?
Many thanks to those taking the time to help here
