Router is a Linksys 1900AC v1
Had a DD-WRT installation go south on me, most likely my fault. I've only done this once before, to a wrt-54g.
Router power and esata lights come on, nothing else, even when an ethernet cable is plugged in. Holding down the reset button does nothing. I was able to connect via USB-> serial using this as a guide: https://www.youtube.com/watch?v=PZYXKAkuJ5w and was able to get the attached putty output. It hangs at that bottom line and goes no further.
Can someone tell me by looking at this if my router is recoverable or not?
There are numerous articles regarding recovering a locked router but I assume you have done this before on a 54G. _________________ Starlink & DSL -> TPLink TL-R470T+

I had connected to the router serially and this is the output that I got when I turned the router on while connected via putty. I was not able to get any further.

You should be able to manually recover to the alternate partition with the 3x power switch.
Then you can overwrite the bad flash. _________________ DD-WRT Installation & Setup TUTORIAL http://www.dd-wrt.com/phpBB2/viewtopic.php?t=311117

Did the router reboot to the alternate partition? Or did it just not work?
The timing on the 3x power switch partition swap has to be spot-on. _________________ DD-WRT Installation & Setup TUTORIAL http://www.dd-wrt.com/phpBB2/viewtopic.php?t=311117

Try it this way:
Turn OFF. Then turn right back ON.
As soon as Power LED comes on...
Turn OFF. Then turn right back ON.
As soon as Power LED comes on...
Turn OFF. Then right back ON and leave it on.
You should see the router reboot within a minute or two along with correct LED behavior (if it worked). _________________ DD-WRT Installation & Setup TUTORIAL http://www.dd-wrt.com/phpBB2/viewtopic.php?t=311117

Sorry for the delay...wired up a connector to get a better connection to the serial port (FYI 3D printer stepper motors use the same white connector, just had to swap 1 wired) and tried a different USB adapter.
Unfortunately, still seeing the same output. Tried the 3x power switch reset a number of times, and no luck. Is this bricked, or can it be fixed by someone with better tools & knowledge than I possess?

Think your output shows you are connected properly.
There is no option to get the loop broken by a CTRL-X V or ESC or any combination?
Mine had 'similar' bootloop when i bought it (2nd hand).
At a point managed to get the firmware tftpd to it and managed to update both partitions.
Used linksys (?) commands to do this (or was it dd-wrt..unsure which is which).
Sorry don't remember how i got out of this bootloop....
