What do you mean it "works"?I got Dingux working just fine on my HK model as well..... also all the preinstalled stuff worked great, and even custom firmware's worked fine....The problem is when you try to install homebrew apps, and not in Dingux.
A pawed dingoo HK after serial number or not is a non-export model all dingoos being shipped to foreign resellers are non-pawed units. So if your unit has a paw on it it is meant for China only...
