Freeze + Box crash [GM990 Spark E2 PKTeam Hyperion V2 ]

Hi forumers,

My GM990 Spark running on PKTeam Hyperion V2 E2 image and Mgcamd 1.35 keeps freezing when switching channels. It usually crashes and needs restarting from the back switch (remote does not responds once it freezes).
This is my 3rd PKTeam image after Nebula V3 and Hyperion V1, always the same problem.
While Watching an FTA channel that goes encrypted the image freezes and the CAM seems to not reconnect itselt, when restarting it manually or switching the channel it stays Ok no freeze, if no action is done the box freezes
Do you guys have an idea to help me? This is really driving me crazy !

Thank you all for our inputs.

Anyone please ?

Thank you Damian for your reply. Is there any stable E2 image for this box ? I just bought it few months ago... :s

Thanks mate, will try this this weekend.
I got mgcamd 1.35 from PKTeam Blue panel via plugin menu. I've tried also CCcam214 same freezing problems. I never used Oscam, is it possible to run it with my CWS line (newcamd.list file) ? can you please tell me how to set up the Oscam config files ? One last thing, is there something to do on spark partition (never used it neither ) ?

Thank you so much Damian for your support, really appreciate!
