I checked BTN1 with the multimeter, it had 3.23 V across when not pressed and ~0V when pressed so it seemed to be functioning properly. I didn't have any wires connected to the board. I even took a video of it on my phone, see:

(I had some problems with the video not playing correctly, so i'm not sure if it will work for you guys, but basically it shows me unplugging Espruino from USB power, plugging it back in, pressing the reset button, and showing that the Espruino stays in bootloader mode.)
Anyways, after all that, I'm not sure what changed, but through various attempts at disconnects, resets, button mashing, etc.... it somehow got out of bootloader mode and I was able to update the firmware to 1.55 this evening. If someone figures out what causes this I would still like to know, but at least it's fixed for now. Thanks for replying quickly Gordon. Having people remove these small blockers when starting projects is extremely helpful and encouraging that we're not alone with Espruino!
