Before starting:
1. Make sure your Kobo ereader is
already running firmware version
3.17.0 (60588a39fd).
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_3170.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 3.17.0 for your device (See
this thread) and copy it into the 3.17.0_source/ subdirectory. (
Don't extract the firmware zip archive.)
3. Read and edit all the *.patch files in the 3.17.0_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 3.17.0.bat; For Linux/Mac open a terminal, change to the patch_kobo_3170/ subdirectory, and run ./3.17.0.sh from the command line.
5. If there were no errors, copy the resulting KoboRoot.tgz from the 3.17.0_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 3.17.0_source/*.patch files to disable all patches (set patch_enable = `no` for every patch).
2. Repeat steps 4-6 of the procedure above.
