I have the same problem here; on a c2105 though.

Same problem here. Did this problem arise after flashing any custom ROM.
In my case, this problem raised after flashing CM 12.1. Before that it was perfectly alright.

Just flash a Android 4.2.2 based rom, then you can flash stock rom without problems
