Hey!

I have an Hikvision DS-2CD2143G2 camera running V5.7.10 firmware.
My goal is to be able to downgrade the firmware to at least V5.5.x

Using TFTP, I've managed to downgrade the firmware down to V5.7.1 but, looks like Hikvision has the downgrade block active when I try downgrading to V5.5.x ... the camera just keep the brick state.

Can someone please help me? How can I overcome this downgrade block?
