Put the image:

Unplug.

Optional verification step:

# cmp kobo.sdcard.img /dev/sdx && echo OK

should say OK or EOF on kobo.sdcard.img
Thank you for all your explanation. I always used umount before trying to make a partition, so I don't know what could have gone wrong there.

I've performed all the steps you mention (always replacing paths for image and microSD). Unluckily, after confirmation, it says:

Code:
# cmp kobo.sdcard.img /dev/sdx && echo OK

sdcard.img /dev/sdx are different: byte 308, line 1
And obviously, after putting back the microSD (it's the internal one, not the external one) in the ereader, it can't boot. Any idea on anything I could try? I will try to buy a microSD card soon, and fix it once and for all, but right now that is impossible for me.

Thanks again for your help.
