An Autoloader is a standalone executable program provided by BlackBerry (formerly RIM) that contains a complete operating system image. Unlike an Over-The-Air (OTA) update, which patches existing software, an Autoloader wipes the device and installs a fresh copy of the OS.

[1827/1827] system.img written.
[45/45] radio.img written.
Step 5: The 15-Minute Wait Do not disconnect. When the progress bar hits 100%, the autoloader will close, and the Z10 will reboot. The first boot takes 10-20 minutes. You will see a "BlackBerry" logo with a spinning gear. Do not touch it. If it reboots again, that is normal (it is rebuilding the runtime).
