Does any1 have a working image for a Raspberry Pi 3 Model B?

My Psu Went bust and with it the Raspberry pi model A. Since there is no old ones selling atm i just bought a Pi 3 model B and to my supprise it didnt work at all. Dont know whats wrong tbh, I hook up the newly bought 40 to 26 gipo cable to the new Pi 3 and use the Emdje v 3.1 v 5.0 and original. And nothing happens. try to scan the network and cant find any ip belonging to the A2 or Raspberry. Please help if you have an solution to my problem.
