I was looking and had found a ftp server that had a clean complete stock 900bt my flash disk back up and was wondering if there were any more links to it because it went down? Or could somebody share there my flash disk with me. Thx
You can try this link it is for the f90bt. I know there are some minor difference beteween the 900bt and the 90bt but i thnk the software should not be a prob. If so someone will chime in and correct me
thank you for the link minifreezer, you have been a tremendous help ! 
No prob glad i could finally help someone
