B-FIRHT7WWC 1011.1 Cin.. FREE?

[mlgcarra]

I have Samsung HT E5550 I upgraded the firmware from B-FIRHT7WWC 1011.1 to the new one B-FIRHT7WWC 1012.5 (infected with C?),
but I have the previous version (1011, 1) in the PC.
What should I do to re install the previous version?
by the way: B-FIRHT7WWC 1011.1 it?s compatible with the fallowing devices:
HT-E5200
HT-E5500
HT-E5500K
HT-E5530
HT-E5530K
HT-E5550
HT-E5550K
HT-E6500
HT-E8200

Finally the method worked but versi?n 1011.1 is still infected with Cin?.
just read that 1009 also has cinav?.
thanks.
