Black update lumia 620

Guys, simple question. I'm now on Amber + GDR3 developer preview.

Is there a way to FLASH the Black Update , let's say with the swedish Firmware, to my phone through NCS?

I'm asking this because the "can't downgrade to a previous version".

Thanks in advance.

I would suggest you wait a few days, I was about to flash using ncs when the update became available right now in India :)
