SamyGO

Hello everyone.
I own a Samsung TV, EU55HU8200ZXZT model.
Unfortunately the firmware is updated.
I read in this thread that I should downgrade the firmware.

I can unlock the root of this TV?

I would like to record from the TV without any restrictions and be able to see the videos on the Windows computer.

What is the procedure?

Waiting for answers.
Greetings

I have another question on this tv.
Why the TV does not record via USB from UHD tv channels? but only the HD tv channels?
This is a tv restriction?

for the first thread problem. I could not solve.
i tried "destroi decrypt samsung tv recondins", but the "TS" file decrypted it's not read by any media player! it's corrupt!
then I tried to use "SAMYGO PVRDECODER FOR E/F/H series", but I couldn't connect the pc and the tv on FTP!
I should root tv before?
How i can do it? Root tv?
