See the kobopatch - An improved patching system thread for more details.

This firmware version is only available for mark 4/5 devices, for mark 6/7 devices see the thread for firmware 4.9.11311 instead.

BEWARE: The filename for this firmware archive is kobo-update-4.9.11311.zip but the firmware inside the archive is actually version 4.9.11314, so you will need to change the filename to kobo-update-4.9.11314.zip to work with the instructions below.

1. Download kobopatch_4.9.11314.zip from here.
2. Download the firmware from here to the src folder. The zip should be renamed to kobo-update-4.9.11314.zip.
3. Install the firmware on your kobo BEFORE proceeding with the next steps.
4. Enable patches in the files in the src folder (or use the overrides in kobopatch.yaml to keep your options separate).
5. Run kobopatch.bat on Windows, or kobopatch.sh on Linux.
6. If the patching succeeded, a file named KoboRoot.tgz will be created in the out folder. Copy it to the .kobo folder of your device.
