So in your case if the bootimage is broken, your f#cked.

Its easier to just to dd the bootimage, and restore from that, however you need
access to the onboard flash memory which is a tricky situation
Correct.. My guess is their reference to "SD Card" (for older devices and newbs) translates to "eMMC" for the rest of us.

That would seem highly unlikely, but they have to program the chips somehow. My guess it can be done by connecting it by hand according to the datasheet. (soldering involved)

If you want to take a closer look, either enable telnet and manually dump your flash.
Or use this tool I made a while ago: https://www.mobileread.com/forums/sh...43#post3812643

It will dump the Image onto your KOBOeReader/Books partition.
Its about 500/600 mb.
They could do it a few ways that I see...
* Pre-flash the eMMC from serial a default image (unless there's something device specific that is in there)
* Default U-boot enters fastboot/flash mode and then during the update process they update it w/ the version that doesn't
* Magic
