Android Skybox f5s freezing


Hi guys, I have skybox f5s which was stuck on load. I managed to unbrick that. But now I have other problems
1. After rebooting and with LNB connected the box freezes completely after 5 - 10 seconds.
2. Tried few methods mentioned in other threads with no luck.
3. Starting the box on next day it stays at load.

Any idea how to fix this.
Thanks in advance.
