Hello everyone, sorry for the delay. i've been waiting a reply from Kobo Customer Service. My device will be replaced, they are going to ship me one (they pay for it) and i have to send them mine (i pay for it).
For what i've been told it was a hard brick, all by itself because i did not do anything else besides update 2 days earlier and load some books. Im not sure if Calibre had something to do with it but i'll try to edit/convert books without the eReader plugged in.
Thank you all for the time and help. See ya' around
