Instructions for patching firmware 3.19.5761

[GeoffR]

See the Firmware 3.19.5761 discussion thread for information about what has changed in this firmware version.

See the Index to the Metazoa firmware patches thread for a description of what some of these patches do.


Before starting:

1. Make sure your Kobo ereader is already running firmware version 3.19.5761 (0e028f3185). If not, then you need to upgrade before applying this patch.

2. Check that your battery is well charged.


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

1. Download and extract patch_kobo_3195761.zip (attached). [WARNING: If using Windows, make sure the path to the extracted files does not contain any '&', '(', or ')' characters.]

2. Download the Kobo firmware archive version 3.19.5761 for your device (See this thread) and copy it into the 3.19.5761_source/ subdirectory. (Don't extract the firmware zip archive.)

3. Read and edit all the *.patch files in the 3.19.5761_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 3.19.5761.bat; For Linux/Mac open a terminal, change to the patch_kobo_3195761/ subdirectory, and run ./3.19.5761.sh from the command line.

5. If there were no errors, copy the resulting KoboRoot.tgz from the 3.19.5761_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 3.19.5761_source/*.patch files to disable all patches (set patch_enable = `no` for every patch).

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

Notes:

This firmware version seems to be very similar to the previous version 3.19.5613, see the notes about that version if upgrading from an earlier version.

There is a new Kobo Patch GUI being developed that can be used to select which patches you want to enable/disable. With the patches for this firmware version it can also check for mutually-exclusive alternatives.


More patches:

A replacement hyphenation dictionary for the Dutch language. (This dictionary works with all firmware versions, but needs to be re-installed after each firmware update.)

A Turkish language hyphenation dictionary can be found here. Although this firmware version has support for Turkish as a UI language, it doesn't come with a Turkish hyphenation dictionary, so this one will probably remain installed after a firmware update (unless Kobo add their own in a future firmware version.)

A patch for `'Changing the info panel in full size screensaver`

A patch to increase the `Dictionary frame size`

A `Bulgarian keyboard` patch.

A Patch to `Increase The Books Cover Size In The Library`.

A patch to `Allow launching browser without wifi connected`.

A patch to allow search to work with custom dictionaries. See this thread for details.

A Greek keyboard patch. Thanks Embryo.


If you know of any other patches for firmware 3.19.5761 post them in this thread and I'll add them to this post.

Just a note on the GUI.

I'm currently in the process of refactoring the code in preparation for creating a PyQt version. So don't expect a new version with more features just yet!

However, the existing GUI should work without any changes (I have yet to test it though...)

thanks GeoffR!

[Martina Schein]

Thanks, GeoffR.

[outlandos]

Thanks again.

I like to patch the old way, but is there any way i can easily detect which patch i had on previously? Now i have to go from A to Z manually very carefully.

If you have kept your previous patch files, and haven't altered them since you installed them to your Kobo, the GUI will show you which ones you had enabled (the ones already ticked in the GUI)

If you have kept your old patch files, you can use your editor to search for patch_enabled = `yes`. But if you haven't kept them, and you don't remember, then no.

Are the ones used in 3.16.5613 usable as is for 3.19.5761?

All the 3.19.5613 patches marked "Multi-version" can be applied without any change to 3.19.5761.

A Patch `Increase The Books Cover Size In The Library`

[abglek]

hi, i'm new to this thing. getting kobo aura for my wife, hate that sideloading books too tough in formatting, calibre 2nd opinion since sometime the books simply downloaded via build in browser. so far i'm good & happy with all the patch, but only one that bugging me, caption font size - page, chapter number. it's too big & unadjustable. can somebody help me, which part am i wrong?

example:
# Replacement caption font size value for Glo/Aura:
replace_string = 0054, `font-size: 20px;`, `font-size: 14px;` -nothings happened
