Managed to brick a TP-Link RE650 v1

I had the latest snapshot and managed to install Luci but there was a dependency missing. I did connect to Luci via both ethernet and WiFi but deciced to reflash the same snapshot and start over again. Now all lights blink but cannot get a stable ethernet connection of anything. Cannot start it up to get into TFTP either using the reset button.

Any help? I see something about soldering but not sure what to solder.

Anyone with experience??
