What will happen when rolling back to W8.1 and internet got disconnected?

Hello everyone,
I would like to roll back my Nokia Lumia 520 from the Windows Phone 10 TP to Windows 8.1.

And the Problem is I'm having the worst internet speed.

So here is my question: What will happen when rolling back to W8.1 and the internet got disconnected?

Is there any way to download the firmware separately and install it on my mobile separately?

AFAIK and based on my experience, the WPRT will download the firmware first, then deploy it to ur phone, the deployment itself doesn't need internet connection, and you'll be able to run the flashing again without downloading the firmware again since it's already downloaded once, as long as it's for the same phone.

1. Nothing, since the firmware isn't downloaded yet then your phone isn't in the middle of anything.
2. Navifirm

So If internet disconnected that won't be any problem rigt?
