Getting started
From the project's README ("Usage"):
Apply the patch (browser, recommended)
Open the patcher page:
Drop FM-1.fwsc onto the page, or click "choose a file"
When it shows "Official V15 firmware confirmed" and "All 16 patch sites match", click "Download FM-1-macropad.fwsc"
Everything runs inside your browser and the file is not uploaded anywhere (the page is configured to block all network requests). You can also download this repository as a zip and double-click docs/index.html; it works the same way offline.
1'. Apply the patch (Python)
For those who want to read and check the source. Put FM-1.fwsc in the same folder as fm1patch.py and run this in that folder. On Windows, use py instead of python3.
python3 fm1patch.py FM-1.fwsc -o FM-1-macropad.fwsc
Both methods check the SHA-256 of the official firmware and the original bytes at all 16 patch sites before writing anything. If anything does not match, nothing is produced. The output always has SHA-256 4192103baeef0b4601a60e0ec55cd517371ec9834ce2e6b2964647e22aa98641.
Flash it
Start M-UPGRADE and connect the FM-1 over USB. Check that the unit is shown as FM-1 (its current firmware version does not matter).
Click "Select Firmware" and choose FM-1-macropad.fwsc. It should show "Firmware version:51".
Click "Update Firmware" and wait until it reports completion (about 20–60 seconds). The unit restarts by itself. …
