PLEASE NOTE... DOUBLE / TRIPLE CHECK WHAT F/W LEVEL YOU ARE RUNNING. ONLY USE THE VERSION THAT MATCHES YOUR KOBO. CURRENTLY ONLY VERSIONS 2.6.1, 2.8.1, 2.10.0 AND 3.0.0 ARE SUPPORTED. INSTALLING THE WRONG PATCHED FILE WILL BRICK YOUR DEVICE.

ALSO BE AWARE THAT THERE ARE TWO BUILDS OF 2.8.1 F/W. THE PATCHES ARE CURRENTLY FOR THE ORIGINAL 2.8.1 RELEASE, AND NOT THE NEW RELEASE 2.8.1 (b2c05cda0e, 20/09/13)

In the russian forums at http://www.the-ebook.org/ Metazoa has developed and posted a tool for making modifications to Kobo's libnickel.so library file.

In the new version:

• Kobo Patch Generator updated to version 1.5: The correction of minor bugs;
• For 2.10.0 and 3.0.0 new patch 'Search in Library by default': does the default search in the device library, not in the store BookStore;
• For 2.10.0 and 3.0.0 new patch 'Ignore book internal CSS stylesheet': reader ignores the built-in styles of the book, which makes it impossible to have unregulated leading, non-removable fonts, etc.;
• For 2.10.0 and 3.0.0 new patch 'Ignore book TOC navpoints' (disabled by default!) NavPoint reader ignores directives in the file with the contents of the book, as a result - the book is always opened on the first page of the first HTML-section. This patch is disabled by default because there is no guarantee that such behavior is always correct: the authors epub-file is usually knows best which page of the book should be opened first.

Unofficial support for 2.8.1B

Spoiler:

As mentioned above, Kobo re-release 2.8.1 and the patcher as downloaded will not handle this.

The community has done some work on this, and in this post https://www.mobileread.com/forums/sho...&postcount=233 I've posted a zip file that will enable

• My line spacing values
• Custom fonts sizes
• Custom left & right margins

and in https://www.mobileread.com/forums/sho...&postcount=236 DNSB includes the updated needed to handle

• Brightness fine control

Additionally, see https://www.mobileread.com/forums/sho...&postcount=256 for the Page Break patch.

Unofficial support for 2.9.0

Spoiler:

Along the lines of the above patch for 2.8.1B we also have https://www.mobileread.com/forums/sho...&postcount=249 that adds support for 2.9.0.

Again it's a limited subset

• Custom Reading Footer Style
• My line spacing values
• Custom fonts sizes
• Custom left & right margins
• Brightness fine control

Additionally, see https://www.mobileread.com/forums/sho...&postcount=256 for the Page Break patch.

I thought a thread here where people could post their experiences (and share patch files) might be of use.
