Can't downgrade to windows phone 8.1

Hey guys
I've upgraded my Lumia 1520 to windows 10 preview but I want to return to WP8.1
I do the exact thing that they are here but after finishing the software download it says could not download and try again
I've tried it 3 or 4 times but not installing the software
Could you help me about that

Not sure what here is, but this website: FAQ - How can I recover/reset/restore my phone software? - Microsoft - USA will let you download the recovery tool, if it's not installing on the phone, i'm not sure what to tell you, if it's not installing on the pc, try it on another pc, no personal files are left on the PC.

It worked for me even when my entire phone hard drive was empty, maybe try another usb port. Hope this helps!
