Well, if you do it on the device (that is running harmattan) give the following commands. Prerequisite; copy your NEMO tar archive to /home/user/MyDocs for example. ## go to root devel-su ## mount your Nemo partition somewhere to access it mount /dev/mmcblk0p4 -t ext4 /mnt ## now confirm that you REALLY have the correct partition there, this should give you some info about your Nemo release: cat /mnt/etc/meego-release ## now, wipe the stuff you have got there: rm -rf /mnt sync ## now, extract the archive to partition: tar --numeric-owner -xf filename+path-of-your-tar-archive -C /mnt/ sync ## now, detach the mount umount /mnt That's how to do it. Now if everything went dandies, just boot your device and retry booting to Nemo.
