Jolla Releases Early Build of #SailfishForAndroid on Nexus 4

| March 30, 2014 | 4 Replies


Earlier this weekend, I got an email that was sent to “early adopters” of Sailfish for Android. Currently, this in-development build is only for the Nexus 4, but a release will be coming soon for the Samsung Galaxy S3 4G.  Jolla will also publish a Hardware Adaptation Development Kit (HADK) in the next few weeks, that will allow Android devices supporting CyanogenMod 10.1 to have a Sailfish OS port created. (This is something I am really excited about, given I have a Nexus 5, with a Galaxy S5 on the way.)

As it is an early release, don’t do this unless you are happy to accept responsibility if something goes wrong.

Below is a copy from the email. Instructions are below that.

Dear early adopter of SailfishOS for Android devices.

We're kicking off today by publishing the first Early Adopter Release of 
SailfishOS ( for Nexus 4 (mako) to early adopters. Please make 
sure to read this whole e-mail through.

Later we'll be publishing images for Samsung Galaxy S III LTE (i9305) 
and we'll be delivering updated images as we go along for each device as 
hardware support improves. This is just the beginning.

We are also working on the SailfishOS hardware adaptation development 
kit, which describes how to port SailfishOS to existing CyanogenMod 10.1 
devices. Later versions of CM will be supported eventually. We'll 
publish the HADK in the next few weeks if everything goes well.

This installation image is for early adopters only, meaning we know that 
some things are not functional or perhaps even broken -- please see 
release notes below. We think it's worth sharing already now to get all 
of you properly included in the early stages of the project.

We want to build a community around SailfishOS for Android devices that 
is based on mutual trust and respect for what we are all doing. Hence -- 
we ask that whenever you do screenshots, videos, forum or blog posts 
(and we're happy if you do!) or the like, you emphasise that this is an 
under-development snapshot and not a final product release.

It is important for Jolla that the correct expectations are set for 
those who might be users of the final product -- and that they 
understand what they see is not a released product.

WARNING: Modifying or replacing your device’s software may void your 
device’s warranty, lead to data loss, hearing loss, hair loss, financial 
loss, privacy loss, security breaches, or other damage, and therefore 
must be done entirely at your own risk. No one affiliated with this 
project is responsible for your actions but yourself. Good luck.
