My friend I think I know enough , this has nothing to do with the brand of the emmc.
If its not the cmd resistor, then its a corrupted emmc yes, and then since u used a dat0 adapter eather u used a cheap one which most likely will bridge dat0 with dat1 or u installed it wrong ;-).
And if u would be that smart u wouldn't use a dat0 Adapter anyways :-)
If its fresh out of the box has nothing to do with if its a "crappy" emmc or not its most of the time the installers fault ;-)
