Apologies is this has been asked before. My uk moto e 2ng gen 4G lte has just upgraded to Marshmallow 6.0 firmware, would it be possible to downgrade to the previous stock firmware Lollipop 5.0.2 without needing to unlock the bootloader. I read on another site that upgrading firmware works okay however downgrading needs the bootloader to be unlocked? Could someone please advise if this is correct.
