title_body: How can I manually enter number of "Hours Read" in Kobo Aura HD? I did a factory reset on my Kobo Aura HD ( but I did not backup KoboReader.sqlite file ). Now I do not have my previous reading stats.
  
  I don't care about per book statistics but I want to manually enter "total Hours Read", how do I do that ?
  
  UPDATE:
  
  Following is a one row from my KoboReader.sqlite file Event table:
  
  id:             11
  EventType:      1021
  FirstOccurence: 2015-02-17T12:20:34.000
  LastOccurrence: 2015-02-17T12:21:13.000

upvoted_answer: The simplest way (still not simple one) is to connect your reader into linux machine and manually edit KoboReader.sqlite file via sqlite3. Now you need to know the structure of this database and try to find place where total hours read are stored. I don't have any Kobo reader so can't help you more.
