so i followed the instructions to install the Start Menu (as a means of facilitating a koreader installation) .... but koreader wouldn't launch.
i did a factory reset, connected to kobo desktop, it updated the firmware to 3.12
i rebooted
followed step one of the start menu installation
rebooted
followed step two
rebooted
applied bug fix
rebooted
installed koreader ....
and now it works : )
beautifully ....amazing how koreader handles PDF files compared to kobo's own software. Are the Kobo engineers on holiday or something ? .... although i haven't been able to zoom in and out of PDFs, dynamically, with koreader yet. perhaps it's not possible... but anyway so far i'm very happy.
thanks for this Ken
