problem freeze sim201

Hello, I got a dm800 clone Sim201 who was blocked.With the error ' no ca. I didn't have the info on the Boot loader.After research and some testing. I ended up finding what was its Boot loader of origin the SSL76D.But now, I found another problem.The image itself works very well. scan of the providers settings networks, navigation from one menu to the other etc. When I run the decryption with the cccam met it starts normally, but after some time the image eventually hang or has the slightest interaction on the dream via remote control.I tested image than the one that I had installed the first time and ended up updating the boot loader SSL82. But still the same problem. I also changed versions of the emu. I've been 2.11 to 2.13 2.14 and 2.30 and emu also mgcamd but still the same souciSi as someone already had this problem and/or knows the solution. Thanks a lot to him.
