I confirm it is working. So if your system is ver 2.006 you will need to download the testmode.zip from here:

Well I have the same exact issue - with the same unit (but US model) and the same firmware (2.0006). I can't get into testmode aswell. The unit just load normaly.
Can you help us which is the correct testmode.zip that we need to use. Thanks!
