You will need a torx driver for the torx srews later, but first you will have to unscrew the bottom! You will see round bolts, impossible to unscrew! but... they are not round! they are oval. You will need a self made tool!
I took a presicion set of tools in a box ( the cheap ones with little scewdrivers and nutdrivers) Take the nutdriver that fits on the top of the bolt and make (hammer or bent) it oval. You also can take a little coper pipe an make that into an oval. Now you can unscrew these little fellows. The rest is fairly easy!
