EJTAG Tiny Tools carved its niche by offering a cheap entry point into operations that typically require thousand-dollar industrial programmers. 1. Unbricking Consumer Electronics

Most consumer electronics don't come with JTAG pins pre-installed. You will likely need to solder a 14-pin or 10-pin header onto the PCB.
