Does the bluetooth file sharing work in this build?

Hi, no I am afraid. The BT barely works on this device.
I'll build a new image (3.3.0.16) for the hammerhead soon and after that will come back to the BT sharing issue. (Honestly it slipped out my mind as I was busy with the S2 port.) Hopefully will find a solution. I'll keep you posted.

I have good news!
Today I have manged to build a new version 3.3.0.16 image with CM-12.1 base. As I still don't have OBS account this new version cannot be installed as an update OTA. It has to be a fresh install what means you will lose your content. (I suggest to do a backup in TWRP first!)
A few things changed in 3.3 and the result of that Kodi stopped working. (And one of the patches I loved to use, the one that displays the provider name and logo at the bottom on the lock screen.) The owner of these two projects should update their app at some point (or maybe never). However if you can live without these two apps you can download the kernel and the image from the main post.

Happy testing.

Good news, mobile data is fixed!
Instruction is updated in the main post. (To make it work: change Protocol to IP in Settings/Mobile network/Data access point.)

Hi there i tested the Installation.
It works so far but the browser don't work.
"Browser Content not responding"
any advice ?

Well, it depends on what URL you are visiting. This is an old browser, so it is quite possible there are many unsupported web sites.
I think the default home page is http://jolla.com, so this is what the browser is trying to load when you start it. Try to change the default page to something else, or try another browser from openrepos e.g. webcat.
In my experience webcat is loading up pages better that the silica browser.

The 3.4.0.24 build is available to download. Links in the main post.
Don't forget to flash the kernel and TWRP right after you flashed SFOS otherwise you cannot boot!

1. flash the base (cm12.1)
2. flash the SFOS image
3. flash the kernel!!
4. flash TWRP

To the main post, I added some info regarding the battery life. I post it here too.

In my experience the battery life is good. On standby, it can survive 10 days. (Almost 11.) I have checked once or twice daily during this period.

Sailfish OS 4.1.0.24 is available to download. This requires a different kernel. Both of these can be found in the download section in the main post.

Sailfish OS 4.3.0.15 is available to download. This requires a different kernel. Both of these can be found in the download section in the main post. (On Sfos 4.3, BT works normally, without the magic described in the first post.)
