A devise for repairing your receiver after its been F'ed up by installing a malicious file,such as a BL original Pansat clone killer bin to a clone receiver.Actualy any time you load anything(channell list or the lates safe file) to your receiver stuff can happen.Same with updateing your computer bios.Stuff can happen and now you have nothing.
The Jtag connects to certain points on the receiver circuit board and to your computer.It allows you to clear the bios chip and lets you load a file direct to the bios chip.There by restoring the unit to a working state.
Youll never need one if you dont load the wrong thing to your unit.Dont ask me how to use it theres a 100,000 posts everywhere on that subject.And its about as compicated or as easy as you want to make it.
So what you do with it is, try too avoid it, if at all possible.
There like $5 on fleabay if you want to see what one looks like.
