I repeat that I dont have any hacks installed. I have 4.1.0. firmware which I updated from Amazon. Version of Duokan that I tried to install is (K4 None Touch)2012-06-08.C11296.rtm which consists of two directories, K4_4.0.0_to_4.0.1_░Š▒ż and K4_4.1.0_░Š▒ż. I've copied the second because of FW version I have. After that one I tried also (K4 None Touch)2012*06*01.C10934.rtm but with same result.
