Default Can't escape encryption even after flashing stock with Odin

Hi,

I have a galaxy note 3 from Ireland, and I wanted to root it so I followed the instructions I found online. However, when it booted back in after ODIN it still askd me for the encryption pin. If I entered it the phone screen just went black.

So I downloaded the firmware and flashed that with ODIN, and even though it seems to flash successfully it still prompts me for the encrpytion pin. I know the pin, but it just goes to a blank screen.

Can anyone help me with this? I don't care if I lose my files, I just want to get the phone working again!

Thanks.
