Sailfish Alert: Flashing To A Nexus 4 Near You

Early adopters received an email recently regarding a way to flash Jolla’s Sailfish OS onto a Google Nexus 4 device.

Jolla are sticking to their guns by readying the Sailfish OS package for other “Android” based devices in order to help Sailfish gain momentum on a far bigger scale.

Now Google Nexus 4 users, of which there are plenty, have the opportunity to download and run Sailfish on their devices by following some instructions detailed below.

Release notes and Known issues for Early Adopter Release 1 for mako/Nexus 4:

* We have a subtle watermark underneath the UI at all times stating
“SailfishOS development software” “This is not production quality”.
Developer mode is activated at all times.

* Modem and related functionality works, 3G data, SMS but no call audio
(comes in next release). There has been no throughout testing of telephony
related functionality (roaming, airplane mode, data counters,
etc) and any use of this functionality is at your own risk.

* Sensors, Device clock/alarms, Reset device, Bluetooth, USB control + MTP,
Bluetooth, WLAN hotspot, Camera (photography, video recording), and video
playback is not supported in this release.

* Jolla account / Store is removed from the image due to problems with
registering with Jolla infrastructure.

* The image SW is not currently upgradeable, nor is any typically licensed
multimedia codecs (MP3, etc), HERE maps, Android application compatibility
layer, or word prediction for virtual keyboard preinstalled.

* After returning from suspend, UI may be slow for a moment. It is not
possible to double-tap to wake up the device. Power button may fail to wake
device at times, check if you are covering the proximity sensor.
Powering off device puts it into a state of deep slumber; possible to get
out of by holding power button and volume down key with a bit of

* Fingerterm applications may fail to launch during first attempts.

* FPS drop while scrolling in homescreen due to non-batching when rendering
of application icon grid

* Icons/graphics appear unproportionally small in browser toolbar, time
select widget, and Settings favourite icons

* Multiboot / multirom is not supported currently

So it appears there are still some bugs to be ironed out and this is labelled as a “developer release”, but if you’re interested in flashing your Nexus 4 with Sailfish, here are the instructions:

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.

NOTE: You will lose your on-device data, so make a proper backup.
