Well these don't happen often, but a few things might cause it, hitting run too fast and the zip not being finished, or power outage at the worst moment, or a corrupted sdcard come to mind as top reasons. However it happened, here is how to get back up and running.
The last running version of dynaframe should be found at: /home/pi/.dynaframe/dfupdates/...
There will be up to five old versions, and there will be a folder with a date telling you when the update was done.
If you pick the newest folder and move it to /home/pi/Pictures. Then reboot. Then all should come back.
To do this you can use ssh or vnc to access the frame terminal and do things in the frame os directly
If you have a machine that can connect to the share: /// to open the share and you will see logs and media, in logs you might see dfupdates, depending on what image you started from.
cd /home/pi/.dynaframe/dfupdates
ls -l
cp -rv <directory name of latest update> /home/pi/Pictures/dfupdate
sudo reboot
If you have all this same thing, go into the dfupdates folder and you should see dated updates. simply copy the newest to the media folder and rename it dfupdate, and reboot.
finally if Dynaframe isn't booting at all
once you have dfupdate in the pictures directory you may have to use ssh to issue these commands:
sudo chmod +xv /home/pi/Pictures/dfupdates/run.sh
sudo ./home/pi/Pictures/dfupdates/run.sh &
after it's fixed up, do reboot one last time to make sure it all sticks, and if this isn't enough to get you going again, do find us on discord and let us know where you are sticking.
of course at any time you can download the image file, and make a new card, and start fresh
or get a link to download the update file, download it, unzip it, and put it in the right place, we can help with this on discord too.
