This is a simple utility to convert contacts.db
from Sailfish OS into vcard files.
So if your device is softbricked, you can rescue your contacts from /home/nemo/.local/share/system/privileged/Contacts/qtcontacts-sqlite/contacts.db
, and generate vcard files out of them.
Then add the card files back into re-installation. But this is sort of a last resort, I recommend doing proper backups periodically.
PS. Use at your own risk!
