Hi, i had been on cm 11 and it was running 4.4.2. I had already done an OTA update to get on kitkat, so i wasnt wrried about doing another by cm. So i did the update and when my phone rebooted after it just had finished, the phone doesn't want to start. Its been hanging on the samsung galaxy s4 startup screen and refuses to change. I pulled the battery many times out. What should i do?
