Xperia C no green light detected as Serial Device

I rooted Xperia C and installed CMW with Mobile Uncle Tools. Something went terribly wrong and since then the phone is dead. I have tried possibly all the ways on the internet to connect it to my PC (Windows 10) in download mode to use either Sony Companion or wmshua to flash the stock rom but the problem is it isn't detected. All I get under device manager is a Serial Device (COM4) under Ports even though the light is still red on the phone and another thing I have noticed is that it keeps disconnecting and connecting again and again. I have tried installing various drivers, but no luck!
Can you guys please help me out?
