See the
Firmware update - 4.5.9587 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. Check
Settings > Device information to make sure your Kobo ereader is
already running firmware version 4.5.9587 (c77383d7d1). 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_4059587.zip (attached).
2. Download the Kobo firmware archive version 4.5.9587 for your device (See
this thread) and copy it into the 4.5.9587_source/ subdirectory that was created in step 1. (
Don't unzip the firmware archive.)
3. Read and edit all the *.patch files in the 4.5.9587_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 run 4.5.9587.bat (double-click); For Linux/Mac run 4.5.9587.sh (double-click, or right-click + run, or execute 4.5.9587.sh from the command line, or drag 4.5.9587.sh into Terminal, depending on your particular OS/desktop.)
5. If there were no errors, a new 4.5.9587_target/ subdirectory will be created. Copy the KoboRoot.tgz from this 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 4.5.9587_source/*.patch files to disable all patches (set patch_enable = `no` for every patch).
2. Repeat steps 4-6 of the procedure above.
