Flashing gone wrong

[erg]

This is a guide, DO NOT just copy and paste these commands

Code:

#download the img
https://github.com/dreemurrs-embedded/Jumpdrive
https://github.com/dreemurrs-embedded/Pine64-Arch/releases
cd ~/Downloads/
#unzip the image
unxz ./pine64-pinephone.img.xz
#(Plug in the SD or Phone card)
lsblk
#make sure it is un mounted
sudo umount /run/media/user/1FAE-0542/
#Copy over. This will take time
sudo dd if=~/Downloads/pine64-pinephone.img of=/dev/sdd status=progress
sudo sync

Thanks for your advice. As I understand it, that's for flashing Jumpdrive to the SD card? I do have that base covered. I can boot the phone from the SD card with JumpDrive on it, I can telnet to it. I can also boot the phone with the OS image on the SD card no problem.

What I am not managing to do is to flash the actual operating system image onto the eMMc storage using JumpDrive.

Flashing to /dev/sdc fails saying there's not space.
Flashing to dev/sdc1 fails saying there's not space.
Flashing to /dev/sdc2 succeeds but phone does not boot.
