Prerequisites
The device must be connected to the Linux host with the USB cable all the time, unless told to reconnect. The device must also be unlocked and prepared to be flashed, see this page for details.
Configure the host device
Install Android tools.
On Ubuntu do:
sudo apt-get install android-tools* ubuntu-device-flash phablet-tools
Connect the device and type:
lsusb
an output like this will come out:
Bus 004 Device 010: ID 18d1:4ee1 Google Inc. Nexus 4 / 10
18d1 is the vendor id, 4ee1 is the product id.
Numbers may change with other devices.
Create /etc/udev/rules.d/51-android.rules with:
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666" SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee1", SYMLINK+="android_adb" SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee1", SYMLINK+="android_fastboot"
replace vendor and product identifiers with yours.
Now Reload uev's rules to make these changes effective:
sudo udevadm control --reload-rules
Reconnect your device.
Type:
sudo adb devices
your device will be listed.
- Unlock the device
Go to the bootloader:
- Power off the phone
- Keep volume down and power pressed together until the bootloader is shown (the bootloader has an android with the lid open like this: )
From the Linux host type:
sudo fastboot oem unlock
Select "Yes" on the phone using volume keys, confirm pressing the power key once.
Now reboot:
sudo fastboot reboot
Since unlocking wipes data, Android will restart the first time wizard. Let the wizard come up, then press Power button to just power off the phone, you will not need to complete the wizard.
Flash the device
Then connect the device to the host system via USB and boot into bootloader. Power down the phone and then keep volume down and power pressed together until the bootloader is shown (the bootloader has an android with the lid open like this: )
Then on the host type:
ubuntu-device-flash --server="http://kubuntu.plasma-mobile.org" touch \ --channel="kubuntu-phone/devel" --bootstrap --developer-mode \ --password 1234
or, if you want to live on the bleeding edge, flash the latest, untested image with:
ubuntu-device-flash --server="http://kubuntu.plasma-mobile.org" touch \ --channel="kubuntu-phone/devel-proposed" --bootstrap --developer-mode \ --password 1234
("devel-proposed" instead of just "devel")
The device will at some point (ca 5min on my system with fast connection) show the ubuntu logo spinning. This takes another 5 minutes, then it reboots, the google logo shows, and shortly thereafter our spinning ubuntu logo again. After about 1 minute, it's done, and I'm greeted with the welcome screen.
Basic Device Setup
Install a fresh Ubuntu-phone vivid vervet image, either using multirom or by flashing directly. After installation and enabling developer mode, enable ssh:
Make sure the device is connected through your USB port, then log in to it using
sudo adb shell
Writable root
By default, the root filesystem is read-only. Not too useful for developers. A script is run on first boot to make it writable and makes a stamp file ```plasma-phone-devel-setup-run```, check this file exists then run
sudo reboot
and it will boot up with writable root.
The verbose version (so you know what's going on):
sudo touch /userdata/.writable_image sudo touch /userdata/.adb_onlock sudo reboot
Enable SSH access
After reboot above for writeable root it should then run sshd, it will make the stamp file ```plasma-phone-devel-setup2-run```.
If not run it manually:
sudo ssh-setup
The verbose version (so you know what's going on):
sudo bash echo manual > /etc/init/ssh.override echo "exec /usr/sbin/sshd -D -o PasswordAuthentication=yes" >> /etc/init/ssh.override sudo service ssh start sudo setprop persist.service.ssh true sudo reboot
Connect Wifi
We've included a small script which sets up a wifi connection (WPA-PSK) for NetworkManager. This can be run once writeable root is set up (as above).
wifi-setup SSID PASSWORD
If you're using a different security mechanism for your wifi network, it's time to read the nmcli documentation. Look into /usr/bin/wifi-setup for inspiration.
On and on...
Now follow the instructions for your Development Setup to get going.
