MyMPx.org - Which firmware for this rockchip player

I've just bought the below player. Here are the dmesg and lsusb output:

Code:

29884.508030] usb 1-7: new high speed USB device using ehci_hcd and address 15

[29884.648343] usb 1-7: configuration #1 chosen from 1 choice

[29889.681834] scsi 11:0:0:0: Direct-Access     RockChip USB MP3          1.00 PQ: 0 ANSI: 0

Code:

Bus 001 Device 015: ID 071b:3203 Domain Technologies, Inc.

I googled the vendor:device IDs and I successfully identified it as a 2706 rockchip player.
The question is, does all the 2706 firmwares will work with this device. If not, do you know which one will work? What version is the latest one?

Thank you.
