Hi I have not been able to close folders on my BP. I am able to open them with the 2 key but using the star + 0 and pound sign + 0 use to allow me to move in and out of folders. If I reset the unit by taking out the batteries, it takes me back to the root folder. Then I can navigate to the folders where the files and folders are located and start over again. But I need to be able to get out without taking the batteries out. Pressing the 0 key by itself use to allow me to change settings. It may be possible that the 0 is really the problem... Is there a way of resetting the unit sort of like reinstalling the operating system on a PC? Appreciate any advice? Thanks, Keith any
