Instructions for patching firmware 3.16.0

[GeoffR]

Before starting:

1. Make sure your Kobo ereader is already running firmware version 3.16.0 (f56b42a2e1).

2. Check that your battery is well charged.

3. Note that in Windows 8 the instructions below might require the batch file to be run in admistrator mode.


Patching from Windows, Linux (i386/x86_64), or Mac (OS X 10.8-10.9, i386/x86_64):

1. Download and extract patch_kobo_3160.zip (attached). [WARNING: If using Windows, make sure the path to the extracted files does not contain any '&' characters.]

2. Download the Kobo firmware archive version 3.16.0 for your device (See this thread) and copy it into the 3.16.0_source/ subdirectory. (Don't extract.)

3. Read and edit all the *.patch files in the 3.16.0_source/ subdirectory in order to: choose which patches to enable (patch_enable=`yes`) or disable (patch_enable=`no`); and to change some of the replacement values to suit your device and preferences.

4. In Windows double-click 3.16.0.bat; For Linux/Mac open a terminal, change to the patch_kobo_3160/ directory, and run ./3.16.0.sh from the command line.

5. If there were no errors, copy the resulting KoboRoot.tgz from the 3.16.0_target/ subdirectory to the .kobo directory on your ereader.

6. Safely eject and unplug the device, which will then update and restart.


To return your ereader to its original unpatched state:

1. Edit all the 3.16.0_source/*.patch files to disable all patches (set patch_enable = `no` for every patch).

2. Repeat steps 4-6 of the procedure above.

Wow, this was really fast. Thanks, GeoffR!

Notes:

* The `ePub unitless line height` patch is no longer needed as Kobo have fixed the problem in this firmware version.

* New `Fix kepub side bearing font cut-off bug` patch is sligtly different but should work just as well.

* The `Enforce user line spacing in ePubs` patch can no longer be used together with the `ePub fixed/adjustable top/bottom margins` patch.


More patches:

`Disable pinch-to-zoom font resizing` (For use on Aura)

A replacement hyphenation dictionary for the Dutch language.

`Default ePub monospace font`

`Force user line spacing in ePubs` (A stronger replacement for the `Enforce user line spacing in ePubs` patch.)


If you know of any other patches for firmware 3.16.0 post them in this thread and I'll add them to this post.

Thanks.

Arigato!

Thanks much for the quick patch!

Edit: Did I miss the "Search in Library by default" section or was it removed?

Yes. Sorry about that.

Maybe I am missing something, but now epub seems so much slower then kepub, is there a way to remove (in Kepub) the upper line where the book title is showed and add that line to the reading part ?
In Epub I have the whole size of the screen with your patch and about 5 mm (Glo HD) to the page xx of xx txt.
In Kepub I have the same bottom margin,but the title of the book takes a little bit more of my screen, or do I miss a patch that is already there ??

There is no patch to remove the kepub header. There is an option showPageHeader=false that you can add to the [Reading] section of the device's configuration file to remove the title from the kepub header, but it will still leave a much bigger space at the top of the screen than in epubs.
