So first off all what is red light of death It a hard brick state of Xperia C2305/CS39H and it is mostly caused when you are installing a cwm recovery and that won’t match the S1 boot version of your device. Also it is caused by software update not properly installed some errors or incorrect rom flashing not suitable for your device. So before starting to the repairing process read the notes.

Notes :
1. This is official way to recover the device so the warranty will not be voild.

This is because your mother board has some issues if you have ever hard ware damage this is not new thing. Installing custom rom is not different then using stock the custom rom for xperia c are just stock themed so better dont install but sometimes it might able to slove the issue try installing custom rom. And the thing how to install drivers on yout windows pc charge the battery as shown in my guide then connect the usb to pc the go to control panel you will see the device as unidentified device click on it then search for driver on internet it will surely fail to find the hit browse then select the un zip driver file and select the driver it will install it you are done hit thanks if it works best wishes.

There might be some problem with your Phone's hardware. If it's still under warranty, maybe the company can replace your device but at least they can try to repair it for free.

Well this thing doesn't work to install driver first right click on my computer then click on manage then click on device manager then click on your PC name then press add hardware legacy then clan next have disk browse then select the file that it shows setup information from the extracted Zip you are done and don't give wrong information next time.
