How to install Ubuntu Touch over USB?

[PinePhoneCoder]

You can install Ubuntu Touch via a bash script from the SD card on the internal memory like this:

Code:

#!/bin/bash
wget https://ci.ubports.com/job/rootfs/job/rootfs-pinephone/lastSuccessfulBuild/artifact/ubuntu-touch-pinephone.img.gz -q -O -| gunzip | sudo dd of=/dev/mmcblk2 bs=4M
sudo parted /dev/mmcblk2p1 resizepart 1 100%
sudo resize2fs /dev/mmcblk2p1

But how do you install Ubuntu Touch via a USB cable?

From another thread (https://forum.pine64.org/showthread.php?...0#pid60260):

Anyone played with installing over USB?

No, but do you have an idea where to start?

Unless I am very much mistaken you have to use FEL mode. And, again unless I am mistaken, the PinePhone has no magic button key sequences to boot into FEL mode (although I am curious about the reset button ...) so you either have to use the special SDcard image or ensure there is no bootable image on both the SDcard and the eMMC.
