Imported my prs-500 a long time ago, but unfortunately Sony Europe doesn't seem to offer the Nov. 2009 firmware upgrade that includes ePub support and the USB-mass storage interface (needed in recent Calibre versions).
Have found many posts on tools to update firmware on the prs-500 (e.g.
here).
But where can I find the actual firmware itself? Alternatively, would it be possible to dump the firmware from an updated prs-500 and load it onto mine?
Would be grateful for any helpful suggestions
