Hi, I have a fortec lifetime ultra. I just downloaded a bin and the receiver went dead. I read that i need to "Jtag" the receiver! i am fairly new at this. i downloaded a file called fortec star death repair kit. I am required to make a simple Jtag. and honestly i dont know wat a jtag is. May someone explain please and tell me how to make one to go on with reparing my receiver.
