MPU6050 gyroscope not responding

I was testing my MPU6050 and got accelerometer(X,Y,Z) and gyroscope(X,Y,Z) data forming on registers at decentely high sample rate. Looks like I've accidently fed +5v to SDA or SCL the other day and weird things started to happen with MPU6050. Looks like gyroscope got fried. Accelerometer still respond, but at very slow rate. It changes it's value about once a second no matter what clock source I set. Gyroscope stopped responding at all and writes 0 to each axis all the time. Did my MPU6050 got fried? Looks like RPI's current is fatal for i2c?
