Downgrading with the Infectus 2 doesn't work since 2.20 firmware :-(

So we are ...... for the moment.

I've noticed the same problem with 2.20 firmware. I hope there's a work around released soon!

Myself and another member here confirmed 2.10 wont downgrade. And it may even be a problem with 2.01

Not sure if anyone still has infectus in a lower firmware console than 2.10 right now to confirm.

You can't downgrade your fırmware sınce at least the 2.20 fw update or below even.
