Default Android physical acquisition - with OOB data

Hi,

My android device is not a mtd device. It is using mmc technology. I want to physically acquire my device data. I got to know that using dd will not acquire OOB data but only user data. I am unable to use nanddump utility as my device is not a mtd one.

Can any one help me to acquire my device with OOB data too.

Many thanks
