I have Arnova 10d G3 tablet, and immediately after boot-up on home screen it freezes while displaying notification "Preparing SD card"(even when SD card is taken out), nothing on screen is responding and notification doesn't go away(sometimes I can even try to swipe screen and then it freezes mid-swipe). When connected to PC nothing happens. I have already tried to reset to factory setting which is the only option when I enter Recovery Mode. without any changes. Next time I turn it on after factory reset I can go through set-up(setting language, time zone, etc.) in here it some what works, but after time or by opening language selection or time zone selection lists it again freezes up.
