Installing Sailfish OS
Our official instructions for installing Sailfish X are on this web page. There are separate instructions for Windows, Linux and Mac computers. Furthermore, there is a different set of instructions for the Xperia X, Xperia XA2, Xperia 10, Xperia 10 II, and Xperia 10 III.
Jolla Shop has a selection of Sailfish OS “images” for each supported device model. An image means a binary package or a compressed file that contains the executable code of the Sailfish operating system and some tools needed for the installation. The images can be downloaded as zip packages from the Jolla Shop after purchasing the Sailfish X licence. You will need to sign in to the Shop for the download using the same Jolla account that you used for purchasing the licence.
In brief, installing Sailfish can be done on a device connected to a computer with a USB cable. At the moment of connection, the device is forced to a special state, the fastboot state. The computer shall have a directory holding the uncompressed Sailfish image.
The act of programming the code of the operating system to the device is called flashing (as the type of code storage is flash memory).
When installing the Sailfish OS, please follow the official installation instructions.
