Need help

Hi folks first post as Im fine with with windows but not used to an android os,I have a sumvision cyclone x4 that got stuck on the splash screen…I had it back up on an sd card so stuck it in the box but not in sd slot I had it in a holder so I could stick it in my pc to check recovery image was there.Anyway push power lead in and pressed home button didnt give me any options but my green android buddy is on screen withe the blue cage turning and a blue line below moving but its been doing this for an hour,is this right or should it have give me options to do a factory reset or recovery etc,afraid now if I pull the lead or stop it I will brick the box hence the name really stuck!
