I need help on my xbox

I just got a new Hard drive and I installed it to my xbox but it turns on then off then on then off then it flashes red and green

 

your xbox must be modded to install a new hd

 

Has to be modded with a chip

 

chip or tsop flash

 

Will a Xecuter 2.3B Lite mod chip work?
