Replaced iphone 5 battery. Now phone won't charge or power on. Phone just plays charging sound over and over again without turning on. Tried two different wall chargers and tried resetting the phone by holding the home and sleep buttons. Could it be because I'm running iOS 7.1? Thoughts? Are these batteries MFI certified?

Replaced my iphone 5 battery, and now the charging sound keeps playing every five seconds or so and the phone will not power on. I tried resetting the phone by holding the home and sleep button, didn't change anything. Tried another wall charger, no change. Running iOS 7.1 now; could that be the issue? Recommendations? Do these batteries work with iOS 7.1?
