I contacted the Phase One's tech support, and he gave me this file
https://drive.google.com/file/d/0B-KJg7 ... sp=sharing (I'm using Credo50) But I can't get it to work. It says "Cannot find any valid firmware on card" At the end.. the tech gave up and said I should try to bring my camera to the dealer to see if they can manage to update the firmware for me or not.
So If anyone can try and let me know if you guys can update it or not?
