SamyGO

I suggest look in the B series wiki for rooting information

Links below:

Sorry, it is info+menu+mute power. I thought you had an older model. I will delete my error

There is a way to find the real firmware version. It is in the service menu

Yeah, I do not have a C series TV, but in my service menu, the purchase date is completely blank

Yes, sometimes to enter the extended service menu, just do 0000 with the advanced option selected

OK, so according to the service menu, my dad's TV reports a firmware version of 1016.1, which is not compatible with SamyGO

Actually, what you want is /.mtd_boot/MicomCtrl 18

Does my Samsung TV support SamyGO?
