This is a "touch phone" I purchased about a year ago and found it too complicated, so I purchase a flip phone and put the touch phone sim card in it with a view of "binning" the touch phone.
However, I have now an opportunity to use it as an ebook reader for an ebook I am developing on my Debian (linux) pc but I do not know anything about ebook readers or touch phone and I am not succeeding.
What I have succeded so far:
I have read the ebook on my PC with Calibre
I have managed to download FBReader on my PC from which I transfered it on the phone
on which it successfully installed and shows an icon I have also transfered the ebook on the phone
What does not work:
The FBReader and the ebook seem to be in different directories and cannot see each other
When tapping the ebook, it is "rendered" by the browser automatically
When tapping FBReader, I can only get the introduction or the request to install.
The directories of the phone were visible on my PC but then I must have done something wrong because they are not visible any more.

Can anyone see something I should be able to fix in this?

Thank you for your help
