Raspberry Pi Pico MicroPython IoT Device Microcontroller Fix Broken BOOTSEL Issues:
It has dedicated test point pads (TP1–TP6) right in the middle of the board (you can see them in photo, between the two rows of pins, above where GP0/GP1 are labeled). One of those, TP6, is literally the BOOTSEL signal, and one of the others (TP1) is GND — exactly what the button normally shorts together.
Steps:
Unplug the USB cable from the Pico for a moment
Take one of your jumper wires (or just touch the two pads with a single wire/tweezers) and bridge TP6 to a GND pad
Looking at photo, TP6 is the topmost of that middle block of small square pads, and TP1 (or any of the GND-labeled pads nearby, e.g. "GND" next to GP1) works as ground
While holding that short, plug the USB cable into your laptop
Keep holding the bridge for about 2 seconds after plugging in, then release
The Pico should now show up on your computer as a USB drive called RPI-RP2
Tips:
Make sure you're bridging TP6 to GND(TP1), not accidentally two GPIO pads — a wrong short won't hurt anything (these are just logic-level pins) but won't trigger bootloader either
If it doesn't enumerate, try again — timing matters a little (some people find it easier to hold the short first, then plug in USB while still touching)
Once it's in RPI-RP2 mode, drag your .uf2 firmware file onto it like normal
The bootloader shorting worked
What to do now:
Wait a few seconds for it to finish setting up
Open File Explorer (Windows) or Finder (Mac) — you should see a new drive appear named RPI-RP2
If it appears, you're in bootloader mode. Now you just need to flash firmware:
Download a .uf2 file — either:
MicroPython: https://micropython.org/download/RPI_PICO/ (or RPI_PICO2 if this is a Pico 2)
Or whatever firmware/project you were trying to flash originally
Drag and drop the .uf2 file onto the RPI-RP2 drive
The Pico will automatically reboot and run the new firmware once the copy finishes (the drive will disappear — that's normal)
