Still no luck..
I've redownloaded it, tried a different machine and SD reader, 3 different SD cards (256Mb, 512Mb (card provided by Jinke) and 1Gb)
Reset the device a couple of times..
Still the annoying beep and the firmware not found..
I'm on the 1.25.080318 firmware version btw..
*edit* Downloaded latest winrar to be sure, but nope.. still nothing.
Out of suggestions now.. anyone else run into the same problem? Besides formatting using fat16.. other options available??
