That would be ur best option if your switch isnt ipatched(check that first by serialnumber). Yet I recomment to buy a rcm jig (starting from ~dollar at ebay) + payloadinjector / android app. depending on the software version ur on there are coldboot exploits (deja vu for ipatched units at 4.1.0 and below) and warmboot exploits at 1.0.0 but if you upgraded, lets say past 4.1.0 afaik ur best option is the rcm one with fusee primary or hekate.
