Since quite a few people appear to be having issues with the recent Kobo firmware update and their Kobo N236 Aura Edition 2 devices, here is a suggested procedure for recovering when booting your Kobo stalls on the 3 dots screen.
Edit: While this procedure is specific to the Kobo N236 Aura Edition 2, several people have reported that it worked for recovering their Kobo ereaders after a failed firmware update. Basically, follow the first steps and then follow the manual factory reset for your device instead of the one for the N236 in this message.
- Ensure the USB/power cable is plugged in either to a computer or a wall charger.
- Holding power button until the LEDs go off and the screen stops updating (power off)

Before you start:
- Charge your eReader for at least 1 hour.
- Make sure you have access to a Wi Fi connection.
- Connect your eReader to a power source by doing one of the following:
- Turn on your computer and connect an USB power cord to your computer first, and then your eReader.
- Plug the wall charger (not included) to a power outlet, and then connect your eReader to the wall charger.
- Press and hold the power button until the power light on the top-right corner of your eReader turns off. You'll see a 'Powered off' screen when your eReader is turned off. If you don't see 'Powered off', hold the power button for 20+ seconds and release it.
- Release the power button.
- Press and hold the power button on your eReader for 30 seconds.
- Wait for the Restore screen to appear.
- Release the power button.
Your eReader screen will turn black and begin the restoring process. After the restoring process finishes, follow the onscreen instructions to set up your eReader. You'll need access to an active Wi Fi or internet connection to complete setup. You can also use the Kobo Desktop app to set up your eReader using your computer.
