DM7020 (not HD) and Oscam

[clynewolves]

I've got a DM7020 running Cccam. I need to convert it to Oscam. After months of reading and banging my head against the wall I've done it on a DM500, all working fine.
I'm looking for an image with Oscam for the DM7020. I've managed to find one for the HD box but I'm afraid to use it in case it blows the box.
I would be very grateful for any advice please.
Many thanks and Happy New Year!

Been up all last night reading various forums. Had some useful info from a kind person on here.
Since posting I have loaded easy oscam into usr/bin using both DCC and Filezilla. Also loaded it into var/bin. It loaded ok each time but didn't appear anywhere on the menu via tv remote, and there were no channels running.
I also loaded oscam svn 8066 powerpc tuxbox into var/etc/tuxbox. Again it loaded but didn't appear on the menu via tv remote. Cccam went in successfully but missing ESPN, movies and sports.
I'm beginning to think the DM7020 won't support Oscam.
Is there anyone out there who has successfully loaded Oscam onto a DM7020? If so please let me know how.
