Help a noob - Root my samsung TV½

[Irwin1337]

Hi,
After some googling I have ended up here. Please redirect me if I am in the wrong forum.
I am unable to understand how/where to get started.

Model: UE55TU7005K

It is my understanding that I need to do something along the lines of:

1. Get the original firmware for my TV model on a USB device (Where do I get this?)
2. Get the correct SamyGO version for my TV model. (Where?)
3. Unpluck my tv from the internet
4. Somehow use the USB device to install the original firmware. (Plug and play?)
5. Install SamyGO from the USB device?
6. Profit?

Any help will be much appreciated. Thank you.
