Never mess with chinese crap for programmers.
no need to buy an ICD3 (by the way, WHERE do you find a genuine one at that price?) i would have suggested not to mess with chinese crap for programmers and buy the real PK3 for about 50 or 60, or the olimex clone, which actually work, for about 30.
i always had my pk2 to reflash the pic in my pk3 clone, like in here anyway in the pickit 3 standalone app you should have the tools menu and at the bottom of the menu you should have an option called download operating system if this doesn't work i think you bricked the thing. Aaaah, the chinese clone constantly bricking problem.
