My guide is different than guide in wiki (at least for vanilla/emmc) and i have seen n+1 number of different guides in blogs and here where people FIRST run flasher and AFTER that connect N900. In my opinion these kinds of "little" things matter A LOT.

I think that reason for little variation inguides is because of Win xp/Vista 32&64/ 7 32&64 and it could be that all these OS need a BIT little workflow. I do not know or i´m not sure about this just wild guess.

Guess is not enough in matter of how you did try to flash you emmc/vanilla. Please try again with emmc and with both workflows first mine and then the one in wiki Report here.
