 **Bingo, bongo, you're now in boot selector mode!** If you want to upload a new firmware file ([a ".uf2" file, like "ploopy_headphones_pm420" or something](https://github.com/ploopyco/headphones/releases)), just drag it into the folder, and it'll automatically install on the amplifier and restart itself, in normal operating mode. You're done!
 
+**TIP**: If your firmware is in some kind of strange state and uploading new firmware isn't fixing it, try uploading [a flash nuke](https://learn.adafruit.com/getting-started-with-raspberry-pi-pico-circuitpython/circuitpython#flash-resetting-uf2-3083182) to the amplifier before flashing the new firmware. It wipes the memory of the amplifier completely clean, which can help clear a few types of errors.

 To summarise: if you want to upload new firmware,
 
 1. Put the amplifier into "BOOTSEL" or "boot selector" mode.
