I have a samsung galaxy s3 i9300 and have flashed cyanogen mod 12.1 on it and it has been working fine since the day I flashed it. My phone while I was on the home screen shut off and showed the cyanogen mod boot screen. I wasn't too worried as it wasn't the first time it happened. I wait. It's still on the boot gif. Waiting intensifies. It vibrates. It says booting android. It shuts off again. And so on for about an hour. Now I just get a screen saying encryption unsuccessful. I have not done anything odd such as playing around in twrp in fact the last time I used it was when I flashed the rom. What do I do please help
