Tips????

Is there any advice that high elo players can give to me. I am hardstuck silver and I dont know how I can increase my playstyle of the game. I understand that the solo carry days are gone, so as a jungle main, how can I help push my team to victory with ganks. Ive tried many different types of playstyle in the jungle and none of them have worked in a substantial way. I refuse to blame my teammates because I feel if a player plays a certain way he can win a majority of games. Any tips you can give would help me a lot. Thanks!!!!
