Hi,
@Gordon
I tried to replicate the upload, but the Android tablet is quite old and is giving me trouble with its battery now. If it’s able to revive itself, I’ll be able to do a video with it.
In the friend’s Android, the device said “DFU file not found” even though it was the latest file from the Espruino website.
I didn’t get an exact error message with the Android version, it just crashed when I tried to select the firmware.
I could do a video with my iPhone flashing it, but that might not really help.
It’s definitely set to the bootloader when I try to flash the firmware (says DFU start), then quickly says “disconnect” and reverts back to its base “sw reset” screen.

When I go to connect to the watch, I get a ton of options, like 15, in the Bluetooth connection screen. However, as the guide says, I always pick DfuTarg from the list. None of the others are called Bangle.js, so I’m pretty sure that part’s working as intended.
Thanks for all the suggestions!
