The only additional VirtualBox configuration needed was enabling USB and file-sharing:
- Install Oracle VM VirtualBox Extension Pack (search Google, Oracle website)
- Add <user> to vboxusers group (sudo usermod -aG vboxusers <user>) (relogin or restart Ubuntu after)
- Add filter for Kindle in Recovery Mode in VM USB settings so that VM can see it
- Install VirtualBox Guest Additions on VM (not necessary, but nice to transfer files to/from VM)
I know, it's too late to inform you, but nevertheless... There is working cross-platform command-line replacement of MfgTool: imx_usb_loader
(and there is tl;dr at the end of linked post).
