Download the HADK documentation from

This document mentions configurations required to build Sailfish OS for Nexus 5 (hammerhead). HADK should be followed as it is and this document should be referred only to learn about build configurations specific to Nexus 5.

HADK mentions references to CM 10.1 while Nexus 5 is based on CM 11. All the steps carried out in HADK should be in context of CM 11 only.


Chapter 3

Install CM 11 M9 from instead of CM 10.1 on your device and test the functionality as mentioned in HADK.

Chapter 4

cat <<EOF > $HOME/.hadk.env
export MER_ROOT="[insert value of your choosing]"
export ANDROID_ROOT="$MER_ROOT/android/droid"
export VENDOR="lge"
export DEVICE="hammerhead"
cat <<'EOF' >> $HOME/.mersdkubu.profile
function hadk() { source $HOME/.hadk.env${1:+.$1}; echo "Env setup for $DEVICE"; }
export PS1="HABUILD_SDK [\${DEVICE}] $PS1"
cat <<'EOF' >> $HOME/.mersdk.profile
function hadk() { source $HOME/.hadk.env${1:+.$1}; echo "Env setup for $DEVICE"; }

Chapter 5

sudo mkdir -p $ANDROID_ROOT
sudo chown -R $USER $ANDROID_ROOT
repo init -u git:// -b hybris-11.0
repo sync

Chapter 7&8

part of the packages that need build are in this repo... just add an extra repo to your .hks and save time

HA_REPO1="repo --name=adaptation1-$DEVICE-@RELEASE@ --baseurl=${MW_REPO}"
sed -i -e "/^$HA_REPO.*$/a$HA_REPO1" $KSFL

Known Issues

  • dhcp assigns wrong ip address to host or not at all and it has to be fixed manually to be able to telnet to 2323 :
ifconfig -a and look for the interface name through which Nexus 5 is connected to host
sudo ifconfig <interface_name> broadcast
  • droid-hal-init is sometimes started before /system is mounted and causes race condition with property service. Symptom: you are stuck with a google logo:
sed -i '/%post$/a sed -i \"s;WantedBy;RequiredBy;g\"  \/lib\/systemd\/system\/system.mount' $ANDROID_ROOT/tmp/Jolla-@RELEASE@-$DEVICE-@ARCH@.ks
sed -i '/%post$/a echo \"RequiredBy=droid-hal-init.service\" >> \/lib\/systemd\/system\/' $ANDROID_ROOT/tmp/Jolla-@RELEASE@-$DEVICE-@ARCH@.ks  
sed -i '/%post$/a echo \"[Install]\" >> \/lib\/systemd\/system\/' $ANDROID_ROOT/tmp/Jolla-@RELEASE@-$DEVICE-@ARCH@.ks
    • With all them workarounds above, some boots might still stuck nastily with journal looking only like this:
 A workaround for this was implemented... just setup your time at the first boot
  • you will discover that any zypper operation is slow like hell. Cause two repos that shall not be there adaptation0 and xt9. Workaround: remove them:
zypper rr adaptation0 xt9
  • wireless hotspot is not working... wip? Workaround use usb tethering
echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/iptables -t nat -A POSTROUTING -o rmnet0 -j MASQUERADE
/sbin/iptables -A FORWARD -i rmnet0 -o rndis0 -m state --state RELATED,ESTABLISHED -j ACCEPT
/sbin/iptables -A FORWARD -i rndis0 -o rmnet0 -j ACCEPT

be sure on host the host you have a gateway setup to and a dns eg.

  • if usb-moded is installed you can use the sailfish os usb tethering (unfortunately is known not to work, fixed the package are in MW_REPO)
zypper in usb-moded-connection-sharing-android-config
  • mp3s do not play (google is your friend here.)
  • the usb-moded package is removed so you will not get the phone connecting via usb as storage. Workaround use telnet or ssh
  • usb-moded may cause issues google logo stucked on screen for more tha 4 min... (have not seen them lately). In this case remove them with
rpm -e usb-moded
rpm -e usb-moded-defaults
rpm -e usb-moded-diagnostics-config
rpm -e usb-moded-developer-mode
  • note that if usb-moded are installed ip of the device is, without them
  • note that if you want a working usb-moded you may want to install the following rather than the defaults pulled
rpm -qa | grep usb-moded
usb-moded-0.70-134.1.Nemo.armv7hl (ask phdeswer in the irc channel)
  • while wireless connects to wlan unfortunately after reboot does not connect anymore to the configures network. Workaround. re-add the network
