OTT M8S Android Box - I'm going to smash it. please help.

No, I dont mean I want you to help me smash it...
... I have had this box for about a month, when I first got it, it was fine.
After about 2 weeks it has started resetting itself and crashing.

I tried a factory reset and now its worse than ever, it crashes and resets whenever i start ANY program.

I have tried updating but no updates are showing up.

The firmware on the box doesnt seem to want to update, so I have a few options...

• Update firmware (Im new to android boxes so have no idea where to get new firmware for this or how to update it.
• Hit it with a hammer
• Completely wipe it and install nothing but the OS and try install everything myself... I have no idea how to do that either.

Any help would be appreciated, I'm going to lose my mind soon.
