Thanks! The internal keyboard doesn’t show up here. This is probably because the firmware was half-flashed and doesn’t work/run now. To force it to bootloader ROM mode, you can (I just tried this with my device):
- Open
sudo dmesg -win a terminal to live watch for kernel messages/USB dis/connects. - Unscrew and remove the keyboard frame
- Be careful about the neodymium magnets that are now exposed along the bottom edge (2 left, 2 right). Don’t close the device with the keyboard frame removed, or the magnets can attach to the top half (inconvenient).
- Bridge resistor R5 with needle nose pliers (or similar). I’ll attach some phone pictures here in a moment.
- While it’s bridged, press and hold the PROG button with a finger of the other hand (~3 seconds).
- If that doesn’t react, press the RESET button together with the PROG button (whilst still keeping R5 bridged, otherwise it won’t work!).
- This should make output about a USB mass storage device appear in dmesg.
