i was trying to reinstall 8.1 to my lumia 520 n process suddenly interrupted after 600 mb n just because of power supply problem and i am again trying the same bt it shows some error what should i do now?
i tried after reset my phone still shows same error n today 'windows device recovery tool' has been updated after install updated version shows same error
Then its either your internet connection or something else. I would suggest downloading the firmware files manually from lumiafirmware.com and move it to the WDRT directory.
