I keep getting notifications that there is a system update available for my Sprint Galaxy S3 SPH-L710. I have rooted this phone with no issues until now. Now when I tell the system to update it restarts, the download screen droid appears and starts to download and then it crashes and I have to pull the battery out and do a hard restart to get back to normal. Now I keep getting the notification that an update is available that interrupts any program I'm running but I know it will only make it crash after repeated attempts. Any know how to cure this?
