I've been hacking on a Kobo Touch N905C to use as a dumb e-ink display and it's been working great. I decided I wanted a second unit to play around with as well but as soon as it arrived I immediately ran into issues with getting it connected to my computer using USB. It was clearly running older firmware (no wifi setup option) so I popped the back cover off and was surprised to discover what I thought was N905 hardware with soldered flash instead of an SD card. Did production change during the N905C model run or is this some sort of refurb or case swap?

Is there any way to be sure I will get the newer SD card model when ordering? I thought I was safe with the "N905C" model but apparently not. Maybe the exclamation point on the bottom plus the color logo on the front?
