    You might be right. I shortened an S912 and there were pins on both sides which worked :-P


      Where should I short?

      UP: I find out the pins. PINS 17-18 left side.

        Hi please NAND chip location for Nexbox A95x PRO



          I have successfully un-bricked my TV box. Here are the steps with High Resolution pictures and NAND Chip Mask ROM Mode Short Location

          My TV BOX: T95D Android TV Box Rockchip RK3229 Quad Core BT4.0 RAM 2GB DDR3 ROM 8GB 2.4GHz

          High Resolution Pictures:
 (inside the case)

          Short either pin 13-14 or pin 14-15. The chip is very small thus I cannot be sure.
 (Nand pin short location)

          NAND Chip Name:

          SAMSUNG 634

          Flash tool used: AndroidTool_Release_v2.43

          Rom Used:

          Rom Location:

          - Start AndroidTool_Release_v2.43
          - Load the Rom

          - connect USB Male-Male cable with computer and TV box
          - connect 5v power to the TV Box
          - Short the pin

          - AndroidTool will recognize the box. You now can remove the pin shorting screwdriver or anything else you are using.
          - Press Upgrade and it will flash this ROM to this box.

          - Once flashing is complete the box will reboot itself.
          - Close AndroidTool and enjoy your un-bricked box.

          I hope I did not miss anything here.

            Thank you in advance for your help.


              I have tried everything with my a95x pro but with no succses. BurningTool and windows are not recognizing my device. I have tried to short those two pins also no succses, holding AV reset button pluging USB and adapter. I give up.


                khn993 help me, same problem t95z plus 2% in usb burning tool, the link for the firmware is broken.

                0x10105004/Romcode/Initialize DDR/Read initialize status


                  Box: MXQ pro 4k
                  Model: MXQ-4K-3229XD2-20161117-V0-2
                  1GB RAM
                  8GB Storage

                  I tried shorting all the visible points on board before, but it didn't work.

                  Then i thought it must be because i was using a USB hub, so i plugged the USB cable directly on my pc's back USB port and it worked right on first try ^^

                        Hi All,

                        I am trying to work out where to short the NAND on a board of a friend of mine.
                        I searched all the way over the internet but was not able to find it, untill I came accross this thread, which seemed hopeful but sadly I can also not find it here so far.
                        Maybe this will change it.
                        The board is exactly the same as these 2 posts but I cannot seem to find anyone who found it for this specific board.
                        Can someone help me please?
                        See posts:

                        Thanks in advance for your time!

                                A5X MAX PLUS, bricked, just red light, PC not recognize it.
                                Tried all pins from the picture you marked but no success.
                                Can you tell me right order to do it, do I need power adapter also, do I need to press Recovery button, what pins exactly need to short.
