  3. Hi Adie278, what's your ROM version using now? try to do a full factory reset first before flashing, check all the drivers, disable KIES and any Antivirus, Check PC usb port and cable wire.

  8. Hi Bracos, you can still revert back to your previous firmware if the stock ROM is available online. Just remember the firmware build version.. Anyway a Europe firmware version may have a German language also on it.
