Requirements:
Before you start to download anything, please read all this through carefully.
The first requirement is your device must be rooted and you should be able to install a custom recovery (preferably TWRP) onto it.

Installation instructions:
1. Download all files, LOS14.1 zip, Sailfish OS zip and twrp2.8.7.img to the external SD card on the phone
2. Reboot into TWRP (Hold buttons: Power on + Home + Volume up)
At this point you should install TWRP 2.8.7 as the installation work the best with this recovery.
Once you flashed TWRP 2.8.7, please reboot into recovery and continue the process.

3. Do a factory reset
4. Format data to remove any encryption or other residues
5. Still in recovery, flash the LOS14.1 image
6. Still in recovery, flash Sailfish Os image
7. Reboot
8. Enjoy the latest (4.6.0.13) Sailfish OS on your Note 4 (treltexx). :)
You will need patience as the first boot will take for a while. Then you can go through the initial Sailfish OS set up.

This Sailfish OS Android HAL is based on LOS 14.1.

Sailfish OS 4.6.0.13 for Note 4 (treltexx) - 25/09/2024
Sailfish OS 4.5.0.18 for Note 4 (treltexx) - 05/03/2023

Boot logo updater for Note4 (treltexx)
kernel for lxc support (no longer need from sfos 4.4 build)
fix for 'Private number' calls (no longer need from sfos 4.4 build)

Problems/Solutions:

Problem: LXC container doesn't start.
Solution: In TWRP install the kernel for lxc support. (This is included since sfos 4.4 builds.)
Problem: Incoming calls are not displaying the number only the 'Private call' text.
Solution: Install the fix for 'Private number' calls rpm. (This is included since sfos 4.4 builds.)

Some useful patches:

Patchmanager 3.0
More folder icons
Operator name at bottom (Stopped working on 3.3.0.16)
Silica mail (transparent background) - Well documented here

Apps from Openrepos
Apart from the Jolla store there are plenty of other, community made apps in Openrepos. There is a user-friendly app to install/remove apps from this source called Storeman. It can be downloaded and install from this location: Storeman

Debug/login/troubleshooting:
In Ubuntu, connect USB cable. telnet 192.168.2.15 2323 or SSH nemo@192.168.2.15.

Notes:

On Sailfish OS, as it is a Linux system, you cannot install/run any android apps.

How to make a backup/restore with TWRP:
You can boot into TWRP with the usual button combination (Hold buttons: Power on + Home + Volume up) and can make backup/restore.

Battery life
In my experience this build gives a very good battery life (I've tested with a new battery and it drops beteen 5% - 10% overnight with wifi on)

Changelog:

10.10.2020
=========

Custom (Sailfish OS) boot logo

09.10.2020
=========

Sound fix is included, it works out of the box
GPS fixed!
S-Pen works as a mouse! :D To make the cursor visible (thanks for elros34!) you need to install:
1. Patchmanager 3 from openrepos
2. mousetracker
3. amend '/var/lib/environment/compositor/droid-hal-device.conf' file, add the -plugin evdevmouse:abs:/dev/input/event3 to the end of LIPSTICK_OPTIONS. (That line should look like this:
  
  Code:
  
  LIPSTICK_OPTIONS=-plugin evdevtouch -plugin evdevkeyboard:keymap=/usr/share/qt5/keymaps/droid.qmap -plugin evdevmouse:abs:/dev/input/event3
4. as final step apply the moustracker patch in Settings/Patchmanager, then restart the services (pulley menu in Patchmanager) or reboot, then pull out the S-Pen and use it as a stylus/mouse.
  (Note: As patchmanager doesn't yet work when the default user is defaultuser, the instruction above works only on sfos 3.3.0.16 or the OTA updated 4.0.1.48. On fresh sfos 4.0.1.48 install you need to install the mousetracker and manually apply the patch from it.)

Sound - Please download the 'Sound fix script for Note4 (treltexx)' and save it into /home/nemo/Download, then give it executable permission and run as root or do the following:
1. Download the 'Sound fix script for Note4 (treltexx)' and save it into /home/nemo/Download
2. goto Settings/Developer tools, enter a Password and save it
3. start the Fingerterm app and within, issue the following commands

S-Pen WIP

Extra 1: Change boot logo, Download warning image, Charring image and Download image for Sailfish OS like. :D
Simply download the Note4-Boot-Logo-Updater_by_edp17.zip from the download section and flash it with TWRP.
Important!: Once the zip is flashed, boot into recovery again, then you can boot into Sailfish OS.

To revert these images back to original:
Download the original param.bin and flash it with heimdal:

Code:

heimdall flash --PARAM param.bin

Extra 2: Desktop Linux distro install/run on the Note 4!
1. First flash the kernel from the Downloads section (in a later build this will be included)
2. Then, install all the following packages:

lxc
lxc-templates
nemo-qml-plugin-dbus-qt5
sailfish-polkit-agent
python3-base
python3-gobject
dbus-python3
lxc-templates-desktop
qxdisplay
harbour-containers
mouse cursor support for SFOS and LXC

3. Once the packages are installed, fire up the LXC and install a distro into it (e.g. Debian SID)
On the Note 4 the harbour-containers GUI doesn't work properly. Fortunately the desktop distro installation can be done from a command line. Here are the steps:

sudo lxc-create -t sfos-download -n mycontainer
follow the instruction and set the distribution (e.g. debian) then the version (e.g. sid) then the architecture (armhf)
example command: sudo lxc-create -t sfos-download -n mycontainer -- --arch armhf --dist debian --release sid
sudo lxc-start -n mycontainer
sudo lxc-attach -n mycontainer
then within the container:
/mnt/guest/setup_desktop.sh
/mnt/guest/setups/debian.sh

4. Once the Desktop distro is installed you can start:
I recommend to use one of these scripts as they save a little time. (Note: You need sudo installed and configured for these scripts!)

Start LXC and desktop in landscape mode with mouse support: debian-mouse-landscape.sh
Start LXC and desktop in portrait mode with mouse support: debian-mouse-portrait.sh
Start LXC and desktop without mouse support: debian.sh

5. Enjoy. :)
