Kobo firmware 3.3.1, kobohack, libnickel

Kobo has shipped another update of the firmware for their devices, new version is 3.3.1. Nothing spectacular new, just a language update it seems. But since kobohack was updated to firmware 3.3.0, I thought about installing it anyway.

As always, the update procedure is well documented, see tag Kobo.


Links to the firmware are available at this thread at MobileRead. The firmware is for Glo/Auro HD is here: kobo-update-3.3.1.zip


As usual (see previous posts), I try to get ssh running on my Kobo, in addition to some library updates. For this I use the kobohack-j project. The latest release is 140426 and is targetting firmware 3.3.0 and up. Direct link to the version 140426.

libnickel patching

There is (since some time) a good thread how to patch libnickel (and now also another library) at this thread at MobileRead. The first post contains a download link for a zip file that works on both Windows and Unix (including Mac).

My Kobo Glo is currently running with the following patches enabled:

  • Unitless ePub line height: see this post
  • Synopsis font size fix
  • Custom reading footer style
  • Freedom to advanced fonts control
