I'm pretty sure it's the original touch. So that would be a Mark3 version which I downloaded from
https://wiki.mobileread.com/wiki/Kobo_Firmware_Releases
The bottom of the kobo shows model N905 and the version file on it shows a bunch of numbers followed by 00000000-0000-0000-0000-000000000310, so I'm pretty sure it's a Mark3 kobo touch.
Regarding not loading, the battery shows fully charged and it's basically a brand new unused kobo - there should be loads of space on it. I will delete the files copy them over again into the .kobo directory using Windows 7
