Would it help if I post a Video about the menu design?
I found a article
http://www.ciao.de/Auvisio_Street_Beat__Test_8305779 and the User says there that this EM861 is from Yifang Digital and there are other Models too and there is one Yifang Model that is hardware identical to a MP3 from another brand. So you can completely mod this Model by the firmware from the other brand,
But he dont say which brand is it.

Any ideas?
PS: I use a prog. called Factory4. The player was detected sucessfully. But if I select the Test function, and run the test it says "No firmware code!".
Do I have to dump the code first? How?
