[Q][Lumia 520] Screen does't turn on

[algnerd]

Hi,

I've a lumia 520 running WP8.1 the problem is it won't turn on even when its plugged to the charger.

I've tried to use Lumia Recovery Tool and it said that my device isn't supported. Now I'm downloading a firmware to flash it but I can't boot in the Microsoft FFU. I've also swapped the battery.

When plug to the PC I hear the an USB device was plugged but nothing else.

What should I do?

Well currently, before doing anything my device is detected as QHSUSB_DLOAD and I've 520;
Google suggested that I follow these steps, Should I?

Yes, you can. It is the same that here.
