OTA Started Without Permission

OTA Update downloaded to my phone, hit remind me later a few times

Towelrooted my phone to manually update to Lollipop so I can keep root

Phone just shut off and is trying to install OTA on its own

Now I'm pissed, every time I turn phone on, it will start the update.

Is there any way to stop this and get back to my Kitkat so that I can manually install Lolli?
