SamyGO

That options available only Video AR Fix V2

Yes.
But if you wanted to enter TV via Telnet, You needed to execute Telnet Enabler App via content library...
Advanced mode enables execution of non existent "/mtd_rwarea/SamyGO.sh" (you needed to create after flashing) but not enables telnet.
But If you use only telnet (or if you are beginner, please select "Telnet Enable" option) you not needed to enable telnet by hand...

Possible if you implement. But I am not implementing that FW in close future.
You can inspect that fix by downloading KEIL ARM tool for windows, IDA and V2 Sources at download section.
I have some other jobs. Low Level Developers could make it possible easily there is a work on that.
