I dont have the problem as I dont have a n900 yet but looking at this thread it drives me nuts. people posting linux commands to solve a windows guys problem... the wiki is missing it out aswell, I wont edit it as I have no clue what the procedure does look like. (there is a windows section but is it realy any help for someone who doesnt know how to use a command-line?)

are there different versions of eMMC flash bins or is this for all the same?

as far as I understand the wiki pages, you flash the eMMC first and then you need to flash the FIASCO image. so if he's able to flash the FIASCO but the eMMC we are stuck their.

maybe someone with knowledge of memtests and eMMC testing might know some test he could do with a terminal to post the results to us
