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.

1. 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.

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.

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.

Install TWRP

TWRP is an alternative recovery image that offers a lot of flexibility and will be used to install Plasma Mobile.

Download TWRP version: http://build.maui-project.org/phone/openrecovery-twrp-2.8.0.1-hammerhead.img

We assume that at this point the phone is off.

Go to the bootloader:

Keep volume down and power pressed together until the bootloader is shown (the bootloader has an android with the lid open like this: )

Now from the Linx host type (make sure the img-file is in the same directory where you start the command):

sudo fastboot flash recovery openrecovery-twrp-2.8.0.1-hammerhead.img

Now:

Press volume up or volume down until the "Recovery Mode" option appears
Confirm pressing the power button

TWRP will now install (this might take a while).

Once installed, the TWRP main menu screen will appear.

Root phone

Tab Reboot
Tab Recovery
Swipe to Reboot
If asked to "Install SuperSU", swipe to confirm and root the device

Flashing...
