Arduino UNO R3 as JTAG programmer

Hi Experts,

I was wondering, How can I use my Arduino as a JTAG debugger/programmer to debrick routers and devices, that does not have output on serial connection. Been through alot of guides but all of them are confusing. Kindly suggest me the simplest possible solution.

Could be difficult. Each device will have their own protocol of what the JTAG data represent.
The pinout of what to connect the Arduino to are not standard either.
