OK, so my understanding for the rk3066 is that:
a) The flash driver is a closed binary blob - i.e. you can't even read the flash
a1) It's broken enough that people tell you never to dd into a partition,
because as I did it broke it so that the following didn't work.
b) There are at least 2 levels of USB programming protocol
b1) 'rkflashtool' (there are various github copies) can reflash one layer
b2) But if it's too broken for that you're stuck....
b3) .... except with rkbatchtool which is a windows program that
can reflash via USB if you short some pin on the chip to force
some fallback mode.
(Which I've not got a windows box to try; doesn't work in wine,
even with the wine USB hacks)
