Problem after Hard Reset

Hello, a pedalboard seemed to have brick my Dwarf.
I’ve hard reset it using the wiki informations. I succeed in doing it.
But i’ve got a problem, i’ve got no plugin installed. I can install them using the web interface but the pedalboard could not be safed on Dwarf.
I can create a pedal board using the Gui Web interface. I can save it. But when i shut down the Mod Dwarf, it has disappeared…
What can i do ?
