LCD-4 0.1.2

• Fixed: safe mode can be reached over USB again after a crash. If the FM-1 crashed while it was making sound,
  safe mode came up with USB off, so neither the web installer nor M-UPGRADE could find it until it was switched
  off and on. (The same fix as SEQ-4 0.1.0's; tried on an FM-1: two crashes on purpose, safe mode, then an install
  from it.) Nothing else changes.

Install

• From the browser (Chrome or Edge, the FM-1 on USB): the web installer. Or try it in the browser first.
• From the command line: python3 tools/fm1_install.py lcd4-0.1.2.fwsc (Python 3 with pip3 install mido python-rtmidi).
• Going back: the installer's "Back to the stock firmware", or M-VAVE's M-UPGRADE.

The firmware is lcd4-0.1.2.fwsc below; its source is this tag. Installing other firmware is at your own risk; see the manual's Troubleshooting.
