I am having the same thing happen to my system. I wonder if it is affecting a large number of people? For what was supposed to be the flagship HT system from Samsung we seem to have been left out to dry with it in regards to support for apps and updates.
I have problems playing new release titles of 3D blu-ray disc on my HT-C9950W (Avengers, MIB 3, John Carter ....)
Noticed a new firmware released on 19 Dec 2012, version HTB-C9950WWB-1010.2.
Have downloaded the upgrade over the internet fine. But after that it failed to upgrade! Tried upgrading using a USB flash drive instead. Failed also. The message reads"Error detected in upgrade data"
Can someone look into and fix it PLEASE?
