Hello,
I have download the Android installer ( gnu-tar, updater.sh , zImage.bin ).
I Have put the installer and the zubuntu-minimal-rootfs.tar.gz file rename to android-rootfs.tar.gz in SD Card.
I make :
Remove battery and power adapter cable
Wait for 5 seconds
Replace battery, close and lock battery cover
Attach power adapter cable
Keep OK button pressed while pressing on/off switch
From the Japanese menu, choose option 4 (Update), then 2 (SD) and finally Y
Then I answer Y for flash the Kernel and format the Microdrive.
The installer find the android-rootfs.tar.gz and gnu-tar ...
Then the Zaurus Reboot ... And the Kernel start with Kernel Panic

Then I Tray a other Kernel to flash and now the Zaurus dont boot.
When I Boot with Flash Menu, I select 4 and Nothing abend ( no SHARP Pics ) .
