I've tried to short the pin 7-8 (counting from top-right in the image). I also found a lot of threads with different combinations (3-4, 6-7, 7-8, counting pins from different corner, shorting before and after plugin the usb cable, with/without the reset button). I tried them all, but the device never got recognized again by the pc.
I also noticed that there's no nand chip on this side, it's on the other side of the pcb (it's similar to the alfawise a8), it's a little different the other pictures I saw from this model T_T
Could this be damaged by shorting the wrong pings?
Any other solution?
