Dreambox 800hd pvr no ca found

Hi to all. I bought an used dreambox 800hd pvr. I had to flash it because I couldnt connect with ftp to send some files. The previous owner had changed the password.
I flash it propably with a not combatible image. Then when I turn it on I get "Sim201 team #84B www.dm800sim2.com error! :ERR01: NO CA FOUND". (photo1)
I have visited all the forums all the posts about this error and I have tried all the fixes. (patched dreamup - NCF SIM2 - DreamBox-OptiFlasher-Pro-Ultimate-E2-v2.0.0.9)
All of them have the same result. They seem to fix the error. Then my dreambox gets an IP. I then flash it with firefox or opera. The upload of the images goes to 100% and stays. There is no REBOOT button on the browser.
Then I plug the power off reconnect it and get again the NO CA FOUND error.
Some NO CA fix programs says that the fix the error but then the box gets wrong IP (192.168.1.77)
And with dreamup I cant flash an image because it says "FILE TOO BIG"
Does anyone have any idea to help me?
