Glo Can't find any configuration file !

Hi there

I own a kobo glo running the last firmware and I'm trying to modify the configuration file but... I can't find it on my reader !
I have no kobo nor .kobo directory on it.

Any clue of what I'm doing wrong ?

My aim is to set the web browser to full screen as I want to transform it into a weather station. The last thing I need is the full screen browsing.

Here is where I am for now :


Many thanks
