How to resume the factory reset?

Dear Sirs,
I want to re-install system for Jetson TK1, How to resume the factory reset?

Please kindly advise me

Start here:

Hey teslalady. I found this page because I had the same question and the comments so far were unhelpful to me. Here’s what I did.

Go download jetpack. You need an account but it looks like you already have one:
https://developer.nvidia.com/embedded/downloads?#?dn=jetpack-for-l4t-2-1

Make sure your USB cable is plugged in to both your computer and your jetson tk1. Once you’ve installed jetpack ($ sh ./JetPack-L4T-2.1-linux-x64.run) You can run “Flash OS” to format your Jetson.

Cheers!

PS- there is an install guide for jetpack below if you are having any trouble installing it.
