    Running Ubuntu Touch on Gemini PDA

Installation

Use prebuild system.img and get the ubports edge rootfs from here.
Boot into TWRP and install it with the JBB's halium-install script.
./halium-install -p ut ubports-touch.rootfs-xenial-edge-armhf.tar.gz system.img
adb push halium-boot.img /tmp

In TWRP, go to Install -> Install image -> /tmp/halium-boot.img -> select boot partition
Some command are needed in order to get Ubuntu Touch running -> either chroot into rootfs.img or boot into rootfs, connect over USB network and remount / read-write:
