Hello.
I have the same problem with my MP4 Player.
I tried several firmwares and I got some of them working but not properly.
This one:
http://www.s1fw.com/plus/download.php?open=0&aid=59663&cid=3
But colors are not properly show in the screen.
And this one:
http://www.s1fw.com/plus/download.php?open=0&aid=1344&cid=3
This one is for a larger IPod nano clone 3rg version, so the screen is twisted.
But at least them work.
I do not what happens with K9129 board is difficult to find firmwares for it. Mayber there would be other compatible boards. Does anyone know about that?
Thank you and I hope it will help!.
