I tried the many combinations of button holding and tried charging it, but still no response. I can't access it at all, it won't start, it's just gone. I can't use any of the features of my rooting toolkit either as it can't recognize the ABD. I was able to access bootloader for a while but when i decided to activate the Recovery mode, i saw the dead android and a warning sign above him.
So, Now it's just completely unresponsive and i can't plug it into a PC. I haven't even seen anything on the internet related to the QHUSB_DLOAD device that keeps appearing. I really need help with this. I can't even find anyone else with this problem, so i'm pretty worried... Also, I'm not used to installing and playing with mobile devices, so try to explain things in clear-ish english so i might actually understand some of the terms you use.
