Looks like these (RK27xx) are starting to appear in unbranded form.
The good news is it should be possible to back up the existing firmware with the help of the "rkusb.tag" file to access the hidden partition. (thanks manderin1)
There are some bargains around on these players and the prices are no more than the old RK26xx series players.
This one is an unbranded version of the KNC 700 player:-
This one is a new Rockchip copy of the Onda vx747, pity it's so much alike as folks are gonna get confused as the real Onda vx747 uses an Ingenics chip which is a different chip altogether.

Anyone buying these unbranded players should take a copy of their firmware straight away to keep as a backup.
Hmm. makes me wonder if the old RK26xx didn't have an hidden partition somewhere, the old .RFW and the new .RKW are similar packed, and get unpacked during the update process, is there a rkusb.tag for older RK26xx Rockchips?
I guess only Rockchip can answer that question. :roll:
