Hi, I've got an X7 Mini that I was hoping to flash, I followed the steps in the guide in order - hold down recovery button on the back, plug in 5v power, plug in USB OTG via the Male-Male USB provided. I can't get the device to a point where the Rockchip BatchTool even notices the device, let alone flash it. Neither Mac OS, nor Windows (both native install and VirtualBox image) notice the box. Nothing is recorded in Device Manager, with or without the drivers. I'm trying to just get it back to the default mode but I can't receive any feedback from the device. The blue LED does not turn on, and no HDMI signal is detected by the display. How can I knock the box back into standard Android mode?
