I recently got a new battery for my s3 and this afternoon i put my phone down and about 5 minutes later back up and it was on the Samsung Galaxy gt 19800.... and then would go black then back the same screen and repeated itself until i put in the charger where it did the same thing but with the charger loading logo i tried to download new firmware and recovery but before anything can be done it turns of then goes back to one of the previously mentioned screens? How can i fix this?
