Hi again, DNSB and also David, thank you guys. Big help for me not to brick my Kobo Aura. My MC is now recognized and I've put some books in it and it worked. I was not able to document the process but I'd say it's easy with my case and read some steps on 2 different posts combined and used only 2 tools (Flash Drive Image Writer and MiniTool® Partition Wizard Home Edition 7.8)
