General :: Rockchip 3066 TV Box - Making Image Of Device For Replicating?

Rockchip 3066 TV Box I am working with. The situation is thus:

I have a number of these boxes, 12 in my possession currently with more on the way

I have successfully rooted the boxes through ADB, none of the one click or other methods worked, but rooting through ADB did.

I have tried using rkdump but unfortunately it cannot find the update.img which I assume to mean it doesn't have one.

What I would like to do is setup a box exactly how I want and then image this off and copy the image to the others

As I mentioned, even though it's a Rockhip based chipset, there's no way I can identify to extract any kind of update.img from it. I have seen through other postings that some of the 3066 based boards no longer use the same cramfs file header/structure the previous 2xxx chipset used so this is probably why.

The big thing is, I just want to mirror the setup to other hardware of exactly the same pedigree.Here is the MTD/partition map:

Code:
1|root@android:/dev # cat /proc/mtd
dev: size erasesize name
mtd0: 00400000 00004000 "misc"[code]....
what the precise format of the copy to and from commands should be assuming this is the way to go about it?

There's a number of applications that ship on the box by default too I need to remove as root, and I'd like to automate everything, hence the idea of imaging as opposed to stepping through all the tasks manually.
