I also need the SD image.
My Kobo Glo died with weird issues a couple of years ago. I decided to resurrect it, today. Tried uploading firmware to /.kobo on the non-linux partition of the SD, but after trying to start it afterwards, the screen shows nothing, still; only the green LED blinks in promisingly random patterns, but for at least 10 minutes now has led to no developments.
Hoping for that image
P. S.
Why isn't it public and is only sent privately?
