Sailfish X - the downloadable Sailfish OS


Sailfish X is Jolla’s officially supported downloadable version of Sailfish OS for selected devices. It’s currently available for the Sony Xperia™ X device, and soon for other devices too. Purchase the software package, install it on your own Xperia™ X device and experience Sailfish OS on this great device.


Our aim is to choose only great devices to run Sailfish X: together with our community we aim for devices, which can support all the essential features of Sailfish OS, and which have great specifications. The first Sailfish X device, Sony Xperia™ X is a stunning device to run Sailfish OS. Its tech specs, camera quality, screen, and design if you like, will take your Sailfish OS experience to the next level. The next devices to run Sailfish X will be Sony Xperia™ XA2, and Gemini PDA, to which you can already download a community version.


Sailfish X is currently aimed for developers and other tech lovers with some skills. This simply means that in order to get the software running properly on your selected device you have to be at least a bit tech savvy to get through the process. Don’t worry though, we have good instructions for you (scroll down on this page).


Sailfish X is an open source project supported by Sony Open Devices. Sailfish community members and other developers and enthusiasts are warmly welcome to contribute, and to build their own SW images from the sources. Please check the instructions from our blog post.


Sailfish X is currently available for Sony Xperia X. During 2018 Sailfish X will be made available for Sony Xperia™ XA2, and Gemini PDA, to which you can already download a community version of Sailfish OS.

By purchasing the Sailfish X package you will get all the following:
Sailfish OS image to flash to your Xperia™ X device
Android support, predictive text input, and MS exchange support as downloads from Jolla Store to your device
Software updates for at least one year, after which a continuation program will follow (see FAQ below)
Clear instructions and support for downloads & installation
Jolla Customer Care service for one year

Current availability: EU, Norway, Switzerland
Price: 49,90€ (including VAT)

You will need to purchase the Sony Xperia X (single or dual SIM version) yourself.
Note: Do not buy carrier locked devices, since those might not work for this purpose.
Also: if you’re buying a 2nd hand device, please check this prior the purchase. See below FAQ for more details.


Our aim is to make the purchase, download & install process as easy as possible. At the moment you need to be tech savvy and have some basic skills to run through the process. We will add new instruction material to this section as the project matures.

The basic process is very simple, just follow these steps:

Here are some of the most asked questions. If you do not find the answer here, please check or email

1. Why is it called Sailfish X?
The ‘X’ refers to the different devices that Sailfish OS can be downloaded to. Please note that this is a marketing name, the software is still called Sailfish OS. 

2. Why do you charge 49.90€ for it?
With the price you get a fully supported commercial version of Sailfish OS that includes commercial components like Android Runtime, and Exchange support. You also get support and updates for your OS from Jolla, and you can support the Sailfish OS development. Jolla has invested a lot time and money for the development of Sailfish OS. Supporting a release officially is also a significant cost and there are licensing costs that Jolla needs to cover when distributing commercial components of Sailfish OS. 

3. Which devices are available for Sailfish X?
Sailfish X will be available for several selected devices in the future. Currently it’s available for Sony Xperia X, but during this year we will launch officially supported versions for Sony Xperia XA2 and the Gemini PDA. The Gemini PDA is already available as a community version – read about it here.

4. Isn’t the Xperia™ X phone quite close to end of sales? How long will it be available?
The device availability is indeed quite close to ending. However, there are a number of channels still offering it, and you can also find lots of second hand devices. The availability depends on the country you live in. We are working hard to introduce Sailfish X to new devices soon.  

5. What happens to my Sailfish X software after one year of purchase, will it still work?
Yes, your software will continue to function and we will continue providing standard Sailfish OS updates to the supported devices as long as feasible. However, we may add additional software to the Sailfish OS asset, which can be subject to separate pricing later on. Further on, with this price, we guarantee Jolla customer care for one year from your purchase. 

6. How long are the software updates running for me?
We offer updates and customer service for at least a year from the software delivery start, which was October 2017. We will update the status in the Autumn 2018. 

7. What computers can I use to download and install Sailfish X to my device?
Sailfish X can be installed on your device using a Linux, Windows or a Mac OS powered computer.

8. Why can’t I use a carrier locked device for this purpose? I have a device, which was originally locked, can I use it?
Unfortunately, Sony does not support unlocking bootloader to install alternative operating systems for devices that have been carrier locked, even after carrier lock has been removed. 

9. Can I move my Sailfish X from my old Xperia X to a new device or do I need to purchase a new license?
The Sailfish X license you’ve bought is meant for one device model, i.e. if you upgrade your hardware to e.g. XA2 in the future you need to purchase a new license. However, if your Xperia X gets broken or is stolen and you want to transfer your license to another Xperia X device (F5121 or F5122) we will transfer it for you.   

10. If I buy a used Xperia X device with Sailfish X already installed, can I use it with my own Jolla Account?
You can use the device with Sailfish OS, but without the licensed content. If you want to have the full experience you need to purchase a new license.  

11. Are you looking into expanding the availability? I live in a country, which is not on the list.
Yes, we are looking into expanding the sales beyond the initial list of countries. We have good progress in a few selected countries. Stay tuned for updates.
