I'm new here, if I'm posting in the wrong board, I apologize.
I am playing around with a Pico W, and I've run into a problem I can't figure out. A couple of days ago, I was using it on a breadboard circuit with a HC-SR04 ultrasonic range module, and I made the mistake of picking it up and pointing it around. It was just printing the distance to the console in Thonny, and all of a sudden it stopped. And since then, I can't seem to get it out of boot loader mode.
I can press the Bootsel button, and it pops up in my file manager. I drag a uf2 file into it and it pauses and then the "mass storage" disappears, as it should BUT... then after a couple of seconds, the RPI-RP2 "storage" just reappears without me doing anything. If I unplug the USB port and then plug it back in, the storage reappears without me pressing the Bootsel button. Thonny doesn't recognize any configured interpreter and the /dev/ttyACM0 device doesn't show up on my Ubuntu machine.
I was playing with it tonight and at one point copied blink_picow.uf2 to it, and it started blinking! So I thought I would try doing a flash_nuke.uf2 and then reload the micropython uf2. No such luck.
I *think* I might have put a main.py file on there from the kit that included the HC-SR04, and I'm wondering if that has something to do with it. I did try the "rename main.py" uf2,, again, nothing.
I really don't understand how it is going into boot loader mode without my pressing the button. Does it sound like maybe I shorted something out on the board/chip? Is it probably just bricked now?
Thanks for any idea on how to recover it.
