Nano won't boot anymore

After a few days of fun tinkering, my nano will no longer boot.

The last thing I did was hot-swap cameras on the CSI connector. The new camera didn’t work so I rebooted from shell. Device went down and never came back up.

Green power led lights up, but no activity on HDMI, ethernet.

Things I’ve tried:

different micro-usb power supply
barrel jack power supply with jumper installed
newly created sd cards
J40 jumpers on reset pins

Things I haven’t tried:

monitoring TTL serial output

Any suggestions on how to resurrect my nano?

Are you able to get UART debugger and see if any boot log shows up?

Hi andyzf1e4,

Any update here? Can your Nano boot up now?
