== 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 [[../FlashingKubuntuPhonePreparation|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:
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.
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 ==
Note that : this method will erase the existing Android system installed on your phone, if you want to keep Android and want to dual boot it, then read [[../MultiROM|MultiROM guide]].
Then connect the device to the host system via USB and boot into bootloader again by first powering down the phone and then keeping volume down and power pressed together until the bootloader is shown.
Then on the host type:
ubuntu-device-flash --server="http://kubuntu.plasma-mobile.org" touch \
--channel="neon-mobile/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="neon-mobile/devel-proposed" --bootstrap --developer-mode \
--password 1234
("devel-proposed" instead of just "devel")
This will start downloading the image and load it on the phone. Afterwards the device will show the Ubuntu logo spinning. This takes about 5 minutes, then it reboots, the google logo shows, and shortly thereafter the spinning Ubuntu logo again. After about 1 minute it's done and you should be greeted with Plasma 5.
== 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
Optionally you can make this shell have bigger 'inner' size by running
stty rows 40 cols 160
This is not needed but will make the line not break when entering long commands. Adjust the rows and cols according to your screen/settings.
=== 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
=== Resizing the root parition ===
In order to have enough space available for installing stuff, you should resize the root partition using
sudo resize-root-partition
This resized your root partition to about 6GB
=== 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 [[Plasma/Mobile/DevelopmentSetup|Development Setup]] to get going.
