Over-the-air programming

For recent XDAndroid releases (since FRX03), it is possible to install the release as a patch against an older release. The advantage is that a patch is much smaller than a full system image, which is usually nearly 70 MB.

In XDAndroid, these patch-form releases are called "OTA," for over-the-air programming, because this patch technique is the same method by which mobile network operators (MNOs) deploy software updates to their customers wirelessly and with minimal disruption for the customer.

OTA updates from MNOs occur more-or-less automatically. For XDAndroid, the OTA update (e.g. "update-FRX03.zip") must be downloaded and placed in the "andboot" directory (or equivalent), and renamed "update.zip". The OTA update will be applied automatically the next time XDAndroid boots. After the update is applied, update.zip will be automatically deleted and the phone will be rebooted.
