We try such an experiment but gives us a failure on "B" Series TVs.
It's same on C series but I remember that I read a post this week in this forum and one C series owner changed it's firmware by using another region firmwares (via altering firmware names...)

I think you have better to find that thread...

I think it is impossible.
We had some B series TV`s where firmwares were swapped and we got bricks or big troubles as result.
C series is more safer (from samsung`s point of view) and flashing/upgrading firmware from different region is dangerous and worthless with low chance to success and expecting result.

Erdem, this TV what you are talking about was hacked with changing firmware names on HotelMode hack usb. TV was not upgraded witch swaped firmware. Not a case.
