Abstract
In one embodiment, a mobile device performs an over-the-air firmware update by writing the updated firmware to a inactive system image partition, and rebooting the device. The security of the OTA update is maintained through checking a plurality of security signatures in an OTA manifest, and the integrity of the data is maintained by checking a hash value of the downloaded system image.
