What is JTAG Box & When it is Used in Android Mobile Phones?

JTAG Means Joint Test Action Group (JTAG) is an industry-standard devised for testing printed circuit boards (PCBs) using boundary Lines and was designed to quickly and easily test and Repair Direct PCBs Memory Chips and Ram.

in Other Easy Words JTAG Box Directly Communicate with the CPU and with the help of CPU’s JTAG Protocol you can access CPU’s peripherals and memory/NAND/eMMC one of this IC & Memory.

According to my Knowledge and Experience JTAG Box is used for repair dead and Brick Android devices that don’t respond to anything and aren’t seen when USB connected. It seems that it’s something done from the physical hardware side of the device to Run or Active the Software.

Main point that has to be understood: JTAG interface only gives the ability to communicate with hardware in just a few simple ways:

1. Reading/Writing Memory 2. Executing MCU code.

Having a JTAG device in hands absolutely does not mean it is easy now to repair a dead Mobile Phone Motherboard. In most cases the board has complex hardware, NAND memories and RAMmemories which are all connected to the main core chipset which, in its turn, is quite intricate. To get access to these memories, sometimes quite a difficult hardware initialization sequences to be performed.

Every new board often requires different kinds of hardware initialization. For example, if a known Qualcomm chipset is used in the current board, it does not mean at all that settings from some previous board with the same chipset onboard will be compatible.

JTAG CONNECTION

How To Find JTAG Pins?

Now you Need To use a special hardware JTAG box which comes with a vast array of cables (different cables for different types of devices), plus specialized software specifically made for your Mobile Phone model. (There exist generic catch-all JTAG boxes that can be loaded with specific microcode instructions for your particular manufactured board. The tricky part is getting the exact microcode for your device’s circuit board. If you use the wrong microcode, it can cause permanent damage.)

JTAG interface uses 4 main signals: TCK, TDI, TDO and TMS. Additionally, there are often present the TRST signal, the RTCKsignal, the NRST signal.

JTAG Box Pins

What Is Mean By Microcode?

The microcode instructions are emitted by the JTAG box attached to the cable, clipped in position on top of the JTAG pins. The box sends a signal to your device to CPU, Memory or Ram. After That You Can Instal/, Copy or Update Your firmware image to your Android Mobile Phone device.

What Type of Cable is Used For Pin Connection?

There Are Main 4 Main Connection. which pins are used for ground (GND), transmit (Tx), receive (RX) and power (PWR). The power is the important one: if the battery is dead, power can still be fed into your Android Mobile Phone device. The JTAG pins are usually 6,8 or More gold pins clustered close to each other.

  1. To find out how the firmware itself performs the initialization of the hardware it runs inside (since if board is dead, there now is no firmware which does these steps, and it is only you now responsible writing proper values at the proper memory locations;
  2. To find out how the chipset accesses external memory (the NAND; NOR memory is not mentioned, since it does not require any complicated movements);
  3. To write code which will be able to communicate with chipset and to send to it data which is to be written to the flash memory.
  4. And of course, to find out what is to be written and to which flash memory locations for the board to be repaired.
