So it turns out that after rebooting the problem still exists. Also re flashing the rootfs didnt fix the issue either. Ultimately, Ive had to put this down to filesystem corruption and reflash the eMMC. I can now confirm that after flashing the eMMC everything is working again YAY! Fortunately this wasnt my phone that was affected but at least I learnt how to reflash the devices should the need arise! Thanks everyone for your help 8)
