We do not have viable repair solutions for your mobile in this state, you could only try to use loader while the phone is in testpoint - COM 1.0. To do so on DC-phoenix go to testpoint tab and select load and temp unlock the bootloader, after doing so you should attempt to flash your phone with stock ROM, no guarantee that this will be enough to revive your mobile though.
