UN46F7500

[songa]

hello, this is my first post here.
I am electronics technician and I have abilities with hardware and firmware (microcontrollers and microprocessors).
I already practiced reverse engineering in other types of equipments.
I'd like to be able to collaborate with my experience.

I have a UN46F7500 and, unfortunately, its firmware was updated (1121).
I believe it may be possible to modify the firmware trough of another way that is not the exploit!
Has this already been tried here? Or really not worth trying?
