During the ROM installation, I damaged the Mecool B2B player (s912, no pro). When starting, it becomes a logo and nothing happens. Can not start recovery (reset method - unplug power cable, press power button, plug power cable), does not respond to SD card with ROM, the computer can not see the device when connecting USB (male to male) and USB Flashing Tool. Unfortunately, the resuscitation of the device by circut pins (as described in other pins 7 and 8) also failed. USB Burning Tool can not see the box when connected to a computer (Windows 10) and pins are pinched. I tried on another computer running Windows 7 and the effect was the same. I will try to get a new USB cable - maybe this is the reason? In the picture, the motherboard of my box. Maybe I should use other pins? Maybe some other ideas?
