Well they go back to factory default.. This is why every "flashing" guide says pull the power.. As weird things happen when you "soft" reboot after flashing the eMMC... > The uEnv.txt is located in the boot partition, on both eMMC and uSD card. > What line specifies in wich order to boot?

The bootrom is "simple" and it is setup to read the eMMC first. Here's the boot order: bootrom loads MLO from eMMC (if that fails it moves to microSD (hence dd if=/dev/zero to eMMC makes booting from microSD work..) MLO loads u-boot.img from eMMC u-boot.img first looks at microSD for uEnv.txt, reads that file in.
