Nemo Mobile distribution installation on a Jolla device

PLEASE NOTE, THE INSTRUCTIONS ARE FOR SEASONED USERS ONLY, DO NOT TRY THE INSTALLATION IF YOU DO NOT KNOW WHAT YOU ARE DOING! 

OFFICIAL STATEMENT FROM JOLLA CARE SAYS:
"Our warranty does not cover issues arising from using unauthorized software on the device. If installing the alternative OS causes problems with the hardware, these are not covered by the warranty even if it happens during the warranty period. The user would likely also lose the benefit of their statutory rights to have errors repaired. In other words, anyone trying this would do it at their own risk, we can’t be responsible for the outcome nor can we publicly encourage people to do this."

ALSO PLEASE DO NOT DISTRIBUTE THE HARDWARE ADAPTATION PACKAGES AS THEY ARE PROPRIETARY AND YOU DO NOT HAVE THE PERMISSION FROM JOLLA TO DO SO. THIS IS WHY I CANNOT PROVIDE YOU WITH THE PACKAGES, ONLY THE MEANS TO EXTRACT THEM FROM A EXISTING DEVICE.

1. Extraction of certain packages from Jollas repositories, with "zypper install -f --download-only" and rsyncing them to a separate directory on the Jolla device:

usb-moded-pc-suite-mode-android
droid-system-sbj
gst-av
jolla-recovery-sbj
gstreamer0.10-colorconv
qt5-qtwayland-wayland_egl
gstreamer0.10-droidcamsrc
gstreamer0.10-droideglsink
nemo-qtmultimedia-plugins-gstvideotexturebackend
gstreamer0.10-omx
gstreamer0.10-ffmpeg
hybris-libsensorfw-qt5
qtscenegraph-adaptation
kernel-adaptation-sbj
libhybris-sbj-libEGL
libhybris-sbj-libGLESv2
qt5-qpa-hwcomposer-plugin-sbj
libhybris-sbj-libwayland-egl
sbj-platform-images
sbj-version
sbj-wlan
libhybris-sbj-libhardware
libhybris-sbj
droid-system-packager
nemo-gstreamer0.10-interfaces

2. Copy over the aforementioned packages to a directory in which the Mer SDK resides and can access.

3. Copy over configuration files from Jolla device:

rsync -R /etc/dconf/db/vendor.d/locks/screen-rotation.txt /etc/dconf/db/vendor.d/screen-rotation.txt /etc/dsme/battery_levels.conf /etc/dsme/temp_hw_battery.conf /etc/dsme/temp_hw_core.conf /etc/mce/60-als-jolla.ini /etc/mce/60-doubletap-jolla.ini /etc/mce/60-mce-display-blank-timeout.conf /etc/mce/60-mce-display-brightness.conf /etc/mce/60-mce-possible-display-dim-timeouts.conf /etc/ofono/ril_subscription.conf /etc/usb-moded/android-usb-values.ini /etc/usb-moded/usb-moded.ini /lib/systemd/system/basic.target.wants/dev-mmcblk0p24.swap /lib/systemd/system/create-swap@.service /lib/systemd/system/dev-mmcblk0p24.swap /lib/udev/rules.d/90-toh.rules /lib/udev/rules.d/999-boston-system.rules /usr/lib/oneshot.d/bdaddr-from-factory-data /usr/lib/oneshot.d/btrfs-autodefrag /usr/lib/oneshot.d/resize-filesystem /usr/lib/qt5/plugins/feedback/qtfeedback-sbj.ini /usr/share/ngfd/plugins.d/ngf-vibra-sbj.ini /usr/share/qt5/keymaps/boston.qmap /usr/share/ssu/board-mappings.d/05-sbj.ini /var/lib/environment/compositor/60-boston-ui.conf /var/lib/environment/nemo/60-multimedia.conf /var/lib/environment/nemo/60-sbj-vibra.conf /var/lib/environment/ofono/noplugin.conf to@dest.mer.machine:adaptation

4. Copy over /sbin/preinit from Jolla device to a separate directory on the Mer SDK host.

5. Create a image using mic2 and Nemo Mobile system packages:
sudo mic cr fs -A armv7hl -o nemo-sbj-armv7hl-devel --pack-to=nemo-sbj-devel.tar.bz2 --record-pkgs=name,url,content,license jolla-sbj-adaptation.ks

The kickstart file is here http://pastebin.com/zZYd0YM7

6. Add the missing configuration files and /sbin/preinit to the created root filesystem package.

7. Copy the root filesystem package to a microSD card. Transfer the microSD card to a Jolla.

8. Reboot jolla to a recovery mode using Volume Down and Power key, use the recovery mode selector to move to a shell.

9. Inside the shell, copy a fresh installation of the sailfish-snapshot script manually to a text editor.

10. Mount the sdcard inside the shell

11. Go to the sdcard directory and issue:
/sdcard # PARTITION=/dev/mmcblk0p28 MOUNTPOINT=/sailfish-snapshot /sailfish-snapshot-script export factory .

12. Back up the current system with sailfish-snapshot:
/sdcard # PARTITION=/dev/mmcblk0p28 MOUNTPOINT=/sailfish-snapshot /sailfish-snapshot-script create prenemo

13. Inject the Nemo Mobile root filesystem package to a new snapshot on the Jolla device, with Jollas default home filesystem:
/sdcard # PARTITION=/dev/mmcblk0p28 MOUNTPOINT=/sailfish-snapshot /sailfish-snapshot-script inject nemo-sbj-devel.tar.bz2 homefs-factory-1.0.4.20.tar.bz2 nemo

14. Make the nemo snapshot the current system:
PARTITION=/dev/mmcblk0p28 MOUNTPOINT=/sailfish-snapshot /sailfish-snapshot-script restore nemo

15. Reboot the Jolla device to activate Nemo Mobile

To get back to SailfishOS:

1. Reboot Jolla back to recovery mode.

2. Enter shell and get sailfish-snapshot to it.

3. PARTITION=/dev/mmcblk0p28 MOUNTPOINT=/sailfish-snapshot /sailfish-snapshot-script restore prenemo

Glacier UI homescreen on Jolla

PLEASE NOTE!
Tampering with custom repositories on Jolla might leave you with a bricked device, please take care to follow instructions and do this only if you really know what you are doing! This requires developer mode to be enabled on your device.
THERE WILL BE BUGS! YOU HAVE BEEN WARNED!
PLEASE NOTE!

First, download a couple of RPM packages, package1 and package2 (for glacier gallery download this package). Then in your device, preferably do this over ssh, do this:

devel-su
ssu ar http://repo.merproject.org/obs/nemo:/devel:/mw/latest_armv7hl/ nemo-devel-mw
ssu er nemo-devel-mw
ssu ur
pkcon refresh
cd /home/nemo/Downloads
pkcon install-local qt5-qtquickcontrols-nemo-5.1.0-nemo1.armv7hl.rpm
ssu dr nemo-devel-mw
ssu ur
pkcon refresh
pkcon install-local lipstick-glacier-home-qt5-0.0.0-1.armv7hl.rpm
# Then do this:
systemctl-user restart lipstick.service 
# After you have done testing it
pkcon remove lipstick-glacier-home-qt5
pkcon install lipstick-jolla-home-qt5
systemctl-user restart lipstick.service

Thats it then, you have successfully tested the Glacier homescreen experience on your Jolla device, good luck testing it :)
