Installation

Please note that we take no responsibility should problems arise when you install InkBox on your device.

1. Download the latest distribution image for your device.

   To flash InkBox to your eReader we need access to the internal microSD card.

   Warning: Be careful! There is a risk of causing physical damage to your device. When in doubt, search for disassembly guides online.

2. Take off the back cover of your device and remove the internal microSD card. Confirm it has at least 4GB capacity. Insert the card into your computer.

   Warning: If you proceed with the next steps using this card, any data on your ereader will be permanently lost. To prevent this, you can make a full backup of the microSD card or use a different microSD card instead.

3. Use balenaEtcher to flash the InkBox image file to the card.
4. To setup InkBox, eject the microSD card from your PC and insert it in the ereader. Put the back cover on and power it on. It might take a while to boot, so be patient. Setting InkBox up is easy; just follow the instructions on the screen.

Update

Once the install has been done, it is strongly recommended to update to the latest version if one is available.

Download the latest release for your device. Connect your ereader to your PC. Copy the *.upd.isa file to [onboard storage]/.inkbox, eject the device, then unplug the USB cable. InkBox should prompt you with an update dialog. Click on "Update". If you pressed "Cancel" by accident, you can continue by going to Settings -> Page 2 -> Update. The Kobo will reboot and the update process will begin.

Note: If your Kobo gets stuck for longer than 2 minutes on the "Updating" screen and the dots no longer move, hold the power button for 10 seconds and restart the device. The update process should continue normally.

Current Development Goals

InkBox's main developer currently plans to extend support to the Kobo Clara HD. Tolino devices that are rebranded Kobos might work with some images, or not.
