Dreambox Sim

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as I'm more familiar with this and it seems more stable, but when I try to flash this image it tells me it's invalid or out of date.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.

 

downloader bootloader 82 or 84 from dreamboxuk.com. flash image and then bootloader and all sorted.

 

Thanks so much for replying, I'll try this when I get home tonight. One question though, you said to flash the image and then the boot loader, but how do I flash the image first when I get a 'invalid or out of date' message when trying to flash?

 

fair point. flash bootloader, image and then bootloader again

 

Thanks a million mate that worked perfectly!
