Hi guys, I picked up a non-working F900BT unit off a friend. Turns out he messed with it and deleted all the files. I was look to see if any one could send me thiers? I currently have the F90BT files in the unit but from reading around its diffrent. It boots to a black screen, then when you hit menu is goes to the main screen but I cant do anything and then it will restart. I have the latest firmware on it now. Thanks.
