I would suspect that this file has been used all the time for the Kobo desktop software to decide on when to download new firmware and for which device mark type (but I may be wrong here). So this might aid in detecting whether a patched firmware can be applied or whether the user should update first to stock firmware.
  1. model number plus ?? device serial number ??; for instance, N782.... Maybe someone has a better idea what the following information is?
  2. ??
  3. current firmware version, such as 4.12.12111
  4. ???
  5. ???
  6. ???some kind of UID formatted in xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx format???
Yep, I already use that file in some of my other tools. That's what I meant when I said I might detect it. BTW, that last field is the model ID used in upgrade checks. The first is the serial.
