R7000P bricked tftp not possible
USB-TTL through putty
After a firmware update went bad I am unable to reset or reflash my router. I has a USB-TTL cable connected to the internal header but what is coming back looks like complete jibberish, can anyone advise? tftp has not proved possible as the router seems to be cycling itself - 3 ping responses, 3 unreachables, a block more ping responses etc etc. Screenshot attached.
Worked it out. Pin connections from left to right with the router facing you (serial header on front right of board) should be Tx, Rx, Gnd. 4th pin (most right) not connected. Data comes through fine with 115200, 8-N-1 settings

In-line images in these forums must wait for moderator approval, so I
can't see yours yet. (An attached file incurs no such delay.) Some
little description would be nice, even if the pictures were visible.
Copy+paste of plain text can be more useful than pictures of plain text.Hopefully the screenshot is attached this time rather than embedded.
