As I said, I would like, at the moment, to avoid the necessity of a factory reset, until I have finished the book that I'm actually reading (90% read).
Furthermore, I'm a little in a worry that the programs you suggest to install perhaps wouldn't be thus easy to remove in the case they don't work. It should be possible, at least with a pinhole reset, shouldn't it?

Edit: You talk about Linux that will treat the folder as hidden. Do you refer to the Kobo OS?
Edit (2): Hm, the Launcher requires Fw. 2.6.1.
