Mediatech published an android 4.2.2 so I'll try first that version. If you're interested in that file, it is available here: http://www.geniatech.com/down-eng/4.2AT ... 140121.zip It has different DVB apks than migyca's firmware, and they have the same name than my previous version (android 4.1). According to the instructions it can update 4.1 to 4.2.2 directly. I'll post the results once done +info (in spanish): http://foro.androidpc.es/showthread.php?tid=3656
