broose, Have not seen the message before.
What method are you using to extract the firmware?
Can you upload the firmware to
www.uploaded.to and leave me a link so I can check it out.
Also despite the two players looking the same they may not be using the same components. As you can imagine the Chinese MP4 market is pretty cut throat and if a manufacturer can source cheaper components from different suppliers to maximize his profit he will. Consequently the players can differ from batch to batch.
