MR3020 bricked while downgrading

Hello friends,

while downgrading to original firmware on my TP-link MR 3020 its flashing lights only as shown in the below video.

Please help me to unbrick it.

If it is a v3 unit, there is a fairly painless tftp recovery option (see the TOH entry).

The v1.x series requires serial + tftp which is more challenging (you will have to open the case)
