I thought the fix is out already and not in form of new firmware?
"The "Sudden Death" issue is caused by firmware on the (16 GB) VTU00M, revision 0xf1 eMMC (Embedded MultiMedia Card or internal memory if you like). Samsungs Kernel Source Code (Update 7) has been identified as the fix." - Taken from XDA -
Or I missed out something else and the fix is in XELLxxx instead?
Update:
Just read it that for those that motherboard is not changed in Samsung service center and updated to update 7, the update is indeed from those firmware..
Mine just got back last sunday and when I check, it is update 7 though firmware is still 4.1.1...
