    I have had CM12 for about a week now and this problem has only just come up today.
    I went on to Google Chrome and my phone randomly froze and went to a black screen, so I held the power button for a good 15 seconds to see if this would resolve the issue but it turns out my phone got stuck on the boot animation.So while the boot animation was playing, I held down the power button and the volume down button to turn the phone off completely. Once it had turned off I then tried to boot the phone and the same thing happened, it got stuck on the boot animation constantly playing the boot animation.

    I have tried plugging in the charger and booting the phone and the same thing happened.

    Things that I have changed on my phone:

    The phone was updated to CM12 officially via OTA
    I have changed the Themes/Fonts etc

    This is all that has been changed.

    So please help what shall I do?

    Any advice is appreciated.

    I had the same problem. Unfortanetly the only thing working was a factory reset. If only the battery could be removed.... It never failed to work on the samsung

    I had the same problem before and I had to factory reset. (And then I took the chance to move to other custom ROM)

    Later I learnt from a xda member, when stuck at boot after theme change:
    Boot to recovery, mount system, then go to data/system/theme and delete the files.

    Try if this help.
