user78162: I think I have bricked my Nano RP2040. How do I unbrick using a Uno or Mega? I found instructions for using another Nano, but only have the one.

user78181: You don't actually need a Uno or mega to unbrick the device.
You need to place a jumper wire between the GND and REC pins.
This will force the bootloader to load, a mass-storage device will appear on the computer. You can than upload a UF2 file to the drive to restore it.
You can read more about it in the arduino documentation.

If it is really bad you might also need to use a flash_nuke.uf2 file first. This removes all files on the Arduino Nano RP2040 connect.
