    Hi Lou, Sorry for the late reply but glad you got it sorted. You could have just tried rnomvieg the settings which store the window position and last DB opened that are in the parameters file. But deleting the file is fine too, it will get re-created when you next run the application.

    I can’t get the TV OUT to work properly. I can only see the home screen as an picture on the tv. When I connect the device, it goes into landscape mode and when I do any action, it reacts only on the device. The tv still shows the home screen in portrait mode. I’m using the original Samsung MHL cable.

      You can very well apply this update, but for applying this you will have to root the device for accommodating this firmware update. You can either go for any other 4.0.3 firmware version or can also apply with this release. Let us know for any help

    I’m a really ignorant…
    …but I instaled and mainly it works. Until now I miss 2 important (to me…) features: Syn between my computer and S2 don’t run via Kies because Kies can’t recognize the S2 and, also, swipe mode seems be not availlable. This happen because I’m ignorant, or is like that?

    • Amit Bhawani

      Whenever you install a custom ROM onto your phone / device the Kies support is disabled. In order to restore this you need to downgrade your phone back to the stock rom following which Kies would recognize it again. Again if you downgrade you would loose all the latest features like the Jelly Bean OS etc. Its upto you to decide whats better for you.
