Default Rooted d803 - Camera won't connect

Hi there,

I recently rooted my Rogers LG G2 d803 and everything has been working fine except the camera. Whenever I open it (including other camera apps), it just says "Cannot connect to camera" giving me no choice by to quit it. I have googled it, but only found threads regarding different phones, so I don't want to take any actions without knowing if it will work for my phone.

Can someone please give me a suggestion on how to fix this problem? I understand I should flash a kernel, based on other threads, but I don't know which one and how to go about doing it safely.

Thank you!

Oh, and it's running 4.4.2 JB and Kernel is 3.4.0.
