View source for Incremental Updates

Several components of the XDAndroid system are updated continuously as development progresses. To facilitate more widespread testing and easier development, the project has created a few build services for those components.

Advanced users may download live-updated versions of those components to follow development and test changes as they occur.

These updates are intended to be performed at some point after a full installation. For information regarding full system installation, please see the [[Installation Guide]].

==zImage Updates==
Live kernel builds are available from [http://glemsom.users.anapnea.net/android2/htc-msm-linux/ the kernel build service]. These builds are packaged as bzip2 tarballs and can be unpacked with the Unix <tt>tar</tt> utility or the [http://7-zip.org 7-Zip program] on Windows.

To install a kernel update, unpack the tar.bz2 package into your MicroSD card's <tt>andboot</tt> directory. This will create new <tt>zImage_''VERSION''</tt> and <tt>modules-''VERSION''.tar.gz</tt> files in that directory (where VERSION is the new version number).

At this point, you may do either one of the following:
* Edit the <tt>startup.txt</tt> to change the line <tt>set KERNEL zImage</tt> to <tt>set KERNEL zImage_''VERSION''</tt>, OR
* Delete the original <tt>zImage</tt> file and rename the new <tt>zImage_''VERSION''</tt> file to <tt>zImage</tt>.  Delete the original <tt>modules-''VERSION''.tar.gz</tt> file to avoid any confusion as to which modules go to which kernel.  The kernel must match the modules, or several advanced features will not work - the main one being wifi.

The latter method is recommended - to prevent confusion.
The new kernel and modules can now be used by rebooting into XDAndroid

==rootfs Updates==
The rootfs builds are available from [http://files.xdandroid.com/rootfs/ the rootfs build service]. These builds are packaged as common Zip files.

To install a rootfs update, unpack the Zip package into your MicroSD card's <tt>andboot</tt> directory. This will create a new <tt>rootfs-''VERSION''.img</tt> file.

Delete the original <tt>rootfs.img</tt> file. Rename the new <tt>rootfs-''VERSION''.img</tt> file to <tt>rootfs.img</tt>.

The new rootfs can now be used by rebooting into XDAndroid.

==initrd Updates==
New initrd.gz builds are rare. The image should be quite stable, so few updates are expected. Updates are available from [http://files.xdandroid.com/initramfs/ the initramfs build service]. These builds are packaged as gzip files and '''do not''' need to be unpacked.

After downloading an <tt>initrd-''VERSION''.gz</tt> update (where VERSION is the new version number), you may do either one of the following:
* Edit the <tt>startup.txt</tt> file to change the line <tt>set initrd initrd.gz</tt> to <tt>set initrd initrd-''VERSION''.gz</tt>, OR
* Delete the original <tt>initrd.gz</tt> file and rename the new <tt>initrd-''VERSION''.gz</tt> file to <tt>initrd.gz</tt>

The later method is recommended - to prevent confusion.
The new initrd can now be used by rebooting into XDAndroid
