Just FYI so everyone knows - you never want to have the EMMC be the last thing you flash, so anyone suggesting emmc-firmware-emmc doesn't understand the process. Firmware by itself is good. EMMC then firmware is good. Firmware, EMMC, firmware again, also fine. But doing the EMMC last will mess things up because after the firmware is flashed, the N900 internally moves some of the firmware stuff onto the EMMC, so the EMMC flash wipes that moved stuff. That's why you follow up with a firmware flash afterwords.
