Then once the flash is complete remove the sd card and if wanting to use it for storage, format it before inserting it again.
The OTG version is only used to update a prior installed ROM, so not going to be of any use unless there is a prior Zidoo firmware already installed.
The fact that the X2 uses nand as opposed to emmc may account for the slower operation, although I don't know for sure whether the X1 uses nand or faster emmc.
I suspect that it will be emmc because the price is higher.
