How do I install InkBox?
You can download precompiled OS/binaries here and standard Nickel add-ons (outdated, unmaintained) are available here, although support for them has been stopped until further notice. Huge thanks to @fermino for providing free hosting.
On Windows, use balenaEtcher to flash the InkBox image file to the Kobo’s SD card.
On Linux and MacOS, balenaEtcher is the easiest option for command-line-reluctant users.
Alternatively, you can also open a terminal and check the device node of the Kobo’s SD card with
fdisk -l. Then
dd the image to the SD card like this:
xzcat inkbox.xz | dd of=/dev/mmcblk0
IMPORTANT: InkBox OS does NOT provide ANY WARRANTY at all and we are not responsible if you brick your device with one of the factory images or update bundles available online. See legal information for more details.
How do I upgrade InkBox?
To upgrade InkBox, go to http://220.127.116.11/bundles/inkbox/native/update/ and copy the files for your device onto the
.inkbox folder in the USB storage partition.
Note: Prior to version 1.6, InkBox had to be upgraded one version at a time. If your device’s factory image ships with version 1.5, you need to closely follow the upgrade instructions here.
If you install the Nickel add-on, unpack the ‘base’ archive in the root of the onboard storage, not in any subfolder inside it.

How can I contribute?
If you like this project and want to improve it in some way, feel free to fork this repository or one of the subprojects this organization hosts, then make a pull request. I’ll be happy to review it when I have time. You can also join the official Matrix space or Discord server if you’d like to chat a bit.
On the other hand, if you don’t have the appropriate coding skills or just want to help in some way, feel free to make a donation at my PayPal account or on LiberaPay. I’m a student and motivation has been the only thing that has helped me maintain this project for the last months. Developing an entire operating system on my own was not an easy task. I have time, but I like to spend it wisely.
