      Here's the way I do it:
      • Disconnect everything from the device and open up the case. Expose pins to eMMC.
      • Launch USB Burning Tool and load burn package. Hit the Start button.
      • Connect USB cable to USB OTG port.
      • Start shorting adjacent pins on the eMMC using a test probe or tiny metal screwdriver. Hold each for at least a second.
      When you get the right pins, you'll heard the sound of the WorldCup driver discovering the device and USB Burning Tool will automatically begin to flash the burn package.

                Founded another pins (picture 3) but I'm not sure.

                Could anyone help me. Thanks!!!

                  I cannot connect thru USB Burning tool and by using the toothpick method, what else can I do?
                  Where is pins to short on this chip? thanks in advance

                    Hi guys,

                    I have a MXQ 4k with R329Q_V.2.0 board. This one was of a friend of mine who gave it to me bricked, with a non working firmware on it.

                    I've flashed it tons of times, most of the time with wrong firmware, always using the short pin mode to enter in MASKROM mode. Never had a problem.

                    One day I've flashed a firmware (I don't remember which one) and now my box enter in MASKROM mode only by connecting the usb port to the pc (so without shorting any pins) and when I try to flash it, the flashtool gives me the infamous "Prepare IDB FAIL".

                    I suppose I have a faulty NAND now.

                    Anyone can help me with this?

                    THanks!

                        Mask ROM mode
                        who knows more about this Mecool bb2 pro I disassembled I will get UART-USB CABLE
                        and I'm connecting to the computer with which program to load on mecool and which software I download.
                        I attach images to the motherboard

                        confirm if I think correctly

                          hi! i have a5x max+ 4g/32g Fn-Link 6222B-SRB wifi bluetooth module and did flash it on USB-4 right next to AV/reset. unfortunately, loader failed and now it is now bricked. tried the suggested short-pins but cannot detect the maskrom device. so m still looking for the correct pins to short to enter the mask mode and re-flash it. anyone knows this?

                            the boot loop issue on A5X Max has still the bootloader which is easily can be detected using male to male USB cable whereas mine has no way to detect its bootloader. tried using the jtag fix to boot on mmc but cannot boot on microsd. will buy the PL2303 TA USB Cable to use other method, sad that i will receive the item after a month. So i still looking for the trick on how to enter the emmc rom in maskmode.

                              Hello. I need to unbrick the MXQ 4k (not pro version) with the chip RK3229. I don't know which pins are to shortcut. NAND is a Essencore 13t-8gq8t2h5tarc

                              Here are the photos:

                                You should shorts these two pins (7 and 8) while you put the USB cable in the PC with the red circle.

                                After a second, a tool like AndroidTool should recognize your board in MASKROM mode.
