Lol..you are in serious trouble.
You might be wondering how i knew all that.
Cause it happened to my old Desire HD(Still didnt know weather it was a DHD or Inspire 4G.
It turned out it was emmc problem.
You should think of getting a new device or getting a new motherboard as that was what i did.
I followed an unbrick thread here
It never worked for me. But you could try.
I remember i installed a wrong QHSUSB_DLOAD drivers which kind of corrupted the bootloader.
So watch out what drivers you use. There might be a possiblity, your might work.
