  • JTAG LG K430DS through port rj 45

    I have an LG K430DS that I want to make resurrection by JTAG but according to the picture in pin out of riff box 1 I must connect vcc which is inside the plate of riff box 1 ... my query is how I get the vcc so I can connect it to the emmc adapter for riff

    very friendly

    Hi Juan
    1- That picture is real ?, I mean, do you have the adapter? ... If it's true, just connect a USB cable to the USB port of the adapter and the other end to the PC.

    2- Do not forget to connect gnd

        Of course, if it is only that vcc is inside the pcb of the box I know how to design it but with my survey I want to get something to help me do it better

            "my query is how I get the vcc?", "I want to get something to help me do it better"

            Have you ever made a satisfactory connection with your RIFF?.

              There is no need to open box if this adapter is used.
              Simply connect microUSB cable to adapter and thats it.

                when I connect to the usb port to get the 5 volts and connect them to the router, I turn off the indicator LED of 5vdc which I think is almost certain that the PCB is not in good condition to be recovered by JTAG

                  Connect microusb cable to PC USB port.
                  USB port on v1 box is wrongly routed.

                      5v Vcc is provided by USB port. This voltage is then converted on board of adapter into VCC and VCCQ by circuits on that adapter.


                      So, just connect micro USB cable to adapter and PC, connect RJ45 cable to RIFF box ande You're good to go.


                      You can set VCC and VCCQ values by switches on adapter, but it will work even if everything is set to 3.3v if connection is done properly.
                      Just make sure that GND wire is always thick enough and nearest to eMMC.
