error wile rolling back from 10 to 8.1 in lumia 625 during software installation?

[Windows Central Question]

while rolling back from windows 10 to 8.1, the package downloads easily. when i connect my phone the computer detects it. when the software starts installation on the phone and the phone automatically switches off, there is an error about installation failed. the error keeps on showing everytime. it always asks to re strart your phone and try again. but the same error generates eveytime. what should i do now?
