That did indeed do the trick. Thanks a whole bunch! I think hackfin used to call this device 'pink'. It looks exactly like the one on his website (see attached picture), although mine has black plastic. The front simply reads 'Digital Photo Frame'.by victorclaessen - Displays
This is a picture frame that was hacked 4 years ago with the help of hackfin (http://tech.section5.ch/news/?p=77) and has since been lying in a cupboard. It does not seem to work with the current distribution of the dpf-ax toolkit. So I would like to upgrade it to a more modern firmware, if possible.
