Siu: Thanks
J: Already tried, dmesg doesn’t register the device at all though. I just booted a marshmallow based Remix OS from USB (works reasonably well, touchscreen is all over the place though and wi-fi doesn’t work, but apart from it – pleasantly surprised!), enabled usb debugging, connected to my PC – and still nothing. I guess it really must be the cable (fingers crossed it’s nothing internal).
Hans: Why does the Android does not boot? Beats the hell out of me! Not a clue, really. No, I didn’t root, I didn’t change the recovery, all I did was install ext2fsd in Win10. The SD Card was the first place to be gone, still no luck. As for the images – I know, I’d like to use one of them, but how can I use them when I can’t connect the tablet to a PC? Is there a way to flash Android image from running Windows that I’m not aware of?
