Thank you every one, mine are a pair of Od'A. Turned out something was wrong with the original supplied SD cards, both of them! Both the master and companion reported SD Card error when first turned on. But I restarted the machines the error was gone. I quick formatted them every time before copying firmware files. Tried many times and DOS still showed 2.1.0 RC4.
So eventually I quick formatted them using different parameters than the original ones. And voila, 2.2.0beta10 they became!
