See the
Kobo firmware 4.3.9084 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 4.3.9084 (59faa7bc47). 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_4039084.zip (attached).
2. Download the Kobo firmware archive version 4.3.9084 for your device (See
this thread) and copy it into the 4.3.9084_source/ subdirectory. (
Don't unzip the firmware.)
3. Read and edit all the *.patch files in the 4.3.9084_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 4.3.9084bat; For Linux/Mac open a terminal, change to the patch_kobo_4039084/ subdirectory, and run ./4.3.9084.sh from the command line.
5. If there were no errors, copy the resulting KoboRoot.tgz from the 4.3.9084_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 4.3.9084_source/*.patch files to disable all patches (set patch_enable = `no` for every patch).
2. Repeat steps 4-6 of the procedure above.
Note that the following patches are enabled by default:
`Fix page breaks bug`
`Default ePub monospace font (Courier)`
`Custom left & right margins`
`Custom page refresh options`
