I hope this will help other that may have just gotten a X910BT and may not know what to do. I bought mine from some guy on amazon this week and I looked like it was messed with so I was greatful to find this site. I wanted to wipe everything from the unit and I downloaded a new firmware image from this forum(link below). I was suprised since the F90 are are different models but it worked. Then after I the update the bluetooth did not work I must say that I was pissed because I am sure this is why the guy sold it to me. Saving the day someone posted a bluetooth firmware update also(link below)
