FM-1 firmware
How Les scans FM-1 firmware
Les reads the release of each FM-1 firmware it knows about that you'd install, and checks the file. Here is every check in plain words, what a scan can't see, and every firmware we've scanned.
What we check
The file is exactly the one its author published We compare it with the checksum GitHub recorded when the author uploaded it, and with the author's own checksum file when there is one. A build that only comes from the author's site is compared with the checksum the FM-1 Firmware Hub records. A mismatch puts it on hold. It hasn't changed since it came out If the file behind a release changes under the same version, it goes on hold and a person is told at once. We pick the right file When a release has several files, we pick the FM-1 build by name, never just the first one. If we can't tell which is which, we don't show that release as scanned and keep showing the last one we could. It opens cleanly as an FM-1 firmware, nothing damaged Every checksum inside it, its size, and that it's built for the FM-1's chip. It doesn't show up on your computer as a keyboard, mouse or other input device A firmware that does could type on your computer. Any sign of one puts it on hold until a person looks. It doesn't show up as a USB drive or network adapter Any sign of one puts it on hold until a person looks. Its text mentions no computer command tools We look for PowerShell, the Command Prompt, Terminal shells, AppleScript and download commands. Any of them puts it on hold until a person looks. Whether its source code is public Firmwares whose source isn't public are linked, not scanned. Its version exists in its source code The release's version tag has to be in its code's history. If it isn't, we don't show that release as scanned.
We also note
Who uploaded the file: a person, or GitHub building it from the code. How new the author's account is. Issues people have filed about a bricked FM-1 or lost data.
What a scan can't see
What a firmware does while it's running We read the file; we don't run it. A firmware that sets up its USB connection while running could get past this scan. Whether the file was built from its published source code We don't rebuild it to compare. What its update loader does The loader writes the firmware onto your FM-1. We note which loader each firmware uses. Each new one waits for a person to review it, and until then it's listed under Not checked yet. What its startup code does Same as the loader: noted, and waiting for a person's review.
What each status means
Scanned, nothing harmful found We read the release you'd install and no check found a problem. Anything we couldn't check is listed under Not checked yet. It isn't a promise that the firmware is safe. On hold A check found something a person needs to look at. We say what it found. Reviewed by a person A check found something and a person looked at it and accepted it, for example a firmware that is meant to work as a keyboard. We say what was found and why it was accepted. Not scanned yet A newer release came out since our last scan, we couldn't read it, or we couldn't tell which of its files is the FM-1 one. We say which, and show the last release we did scan. Not scanned Its file isn't public, so Les links to it and can't scan it.
Les scans every firmware here whose file is public, and shows what it checked and what it found. A scan lowers the risk; it can't rule it out. Each firmware is made by its author, not by Les. Back up first, and install at your own risk.
Every firmware we've scanned 217 FM-1 firmwares, each with the release we scanned and when. Firmwares whose file isn't public aren't listed: there's nothing to scan. Neither are 9 builds made for other devices, like the SMK-37 keyboard.
Firmwares Les has mapped 33 Each has its own page here, with this scan in full. 26 scanned, nothing harmful found, 2 on hold, 1 reviewed by a person, 4 not scanned yet.
