2 firmware updates are available here: http://www.anythingbutipod.com/forum/showthread.php?t=32690. The update is performed by placing the =Z5Update.dat file in the root of the player or the System/Data folder, depending on the current version you're player is running. This player runs Linux as well as a particular Java virtual machine! Indeed, the firmware UI is made up in Java and all the class are visible (and hacker-able ). Lots of interesting scripts and executable are present in the firmware.
With the help of the Z5 updater (recovery) application we can restore the firmware through the STMP3600 recovery mode. A updater.sb as sent to the device. This ~1,8MB file is really complex since it includes some code to load a Linux kernel with a rootfs-based recovery. Then a z5-fw.dat is sent to the user memory (through UMS) and the process of decryption + flashing begins!
Z5Update?.dat is a mixture of plain and encrypted bytes.
To get the player to present itself as a STMP3600/Player Recovery Class device, hold the middle select button while connecting to USB from the off state. Keep in mind that this device has a sleep mode and the only way to truly turn it off is by pressing in the reset button on the bottom.
