Might be possible, if you backup, reinstall a rom based the same update you're on and then do an advanced restore of just /data, Really depends on what made it soft brick in the first place though. You're pictures won't be touched either way, but contacts, messages, etc are a different story. Hopefully you had your phone synced to Google to backup the contacts at least...
