Difference: SamsungZ5 (r9 vs. r8)
The 7 Z5 has 4 tactile buttons and a touchpad. Screen resolution: 128 x touchpad (directions). Dedicated hold switch 160 (RGB) SoC: Sigmatel STMP360(B) Screen resolution: 128 x 160 (RGB) RAM: ?? -> need to see with UART Radio (where present): Philips TEA5767
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.
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 Linux kernel with a rootfs-based recovery...Then recovery. Then a z5-fw.dat is sent to the user memory (through UMS) and the process of decryption + flashing begins! In the rootfs I extracted I found lots of interesting things: among these perhaps we can start some scripting through a start.sh placed into user memory!
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.
There are 2 UARTs. Need to see the output by using the original firmware. Some strings could be useful to decode/decrypt sb files and/or Z5Update?.dat file...
