Android on Zaurus SL-C1000 installation instructions 
It took much longer than I expected, but I finally did it. Android now works on my Zaurus SL-C1000 as well as on my SL-C3100!

Solution:


The SL-C1000 installer works slightly differently from the SL-C3x00 version. It uses Altboot to boot from a ext3 partitioned SD card. I tried using a the normal procedure where the root filesystem boots from internal flash, but this resulted in socket errors (Connection refused) on startup of Android, as described here. I simply don't know enough about the internal workings of Android as to understand why this is, so I searched for a workaround. Using Altboot is the workaround I came up with. Since Altboot makes it possible to boot from SD or CF apart from the usual internal flash memory, I partitioned and formatted a 1Gb SD card with a ext3 partition. Then I Flashed a slightly customized Poky kernel with Altboot included. The Android root filesystem is extracted to SD and the Zaurus boots from SD. From there it's a simple /start to start Android. That sounds too simple? Let's do a step by step then ;-)

Preparations:


Partition and format your SD card with an ext3 partition. The ext partition is important, if you want this to work. Don't use fat or fat32, use ext3, otherwise you'll regret it. I used sudo gparted on my Ubuntu desktop to make the partitioning and formatting easier. I also added a swap partition for some future Debian experiments, but this isn't necessary. For now you can safely skip the swap-partition step, just make sure you have a ext3 partition formatted (is the importance of the ext3 bit clear enough you think?).

Download:


Download gnu-tar, initrd.bin, zImage.bin, updater.sh and android-root.tar.gz and copy the files to the freshly formatted (ext3) SD memory card.

Flashing:


The flashing is done in the usual way.

1. Remove battery and power adapter cable
2. Wait for 5 seconds
3. Replace battery, close and lock battery cover
4. Attach power adapter cable
5. Keep OK button pressed while pressing on/off switch
6. From the Japanese menu, choose option 4 (Update), then 2 (SD) and finally Y

You're asked if you want to flash the kernel, erase the flash, flash the root filesystem and finally the Android root filesystem. You can except all questions with the defaults (all yes). Only the last bit, the extraction of the Android root filesystem, doesn't work (yet). It doesn't seem to be possible to extract a tar archive to an ext3 formatted SD from the flashing environment (Permission denied). We need to do an extra step because of that unfortunately.

After flashing the Zaurus is rebooted automatically and Altboot is started. Choose option 1 so the Zaurus boots from internal flash memory. Login with root and extract the android root filesystem manually.
cd /media/card
tar -xzpf android-root.tar.gz
Depending on the speed of your SD card this can take a while.

Now, I found out the best way to handle now is doing a full reset (power off, battery remove, 5sec wait, replace battery and power on). The Zaurus boots, and when Altboot starts choose option 3, boot from SD. The first time you do this you'll be asked for some input. One is the administrator password for Altboot and the other is a question if you want to copy the home directory. Answer yes to this question!

The machine now boots from SD and you can login as usual with root.

Starting Android:


To start Android, simply run /start

And now, let the party begin!
