I currently have a Dreambox DM800 HD se that is flashed with the Newnigma 2 image. I would rather change to LT8 as I'm more familiar with this and it seems more stable, but when I try to flash this image it tells me it's invalid or out of date. I believe this is cause my SIM now says SIM 2 & 4 where as on the LT8 image it says SIM201. My question is can I downgrade my SIM so I can install this image and if so how do I go about it? Any info would be greatly appreciated.
