The Firmware Hub · Tools · Rescue

Bring back a stuck FM-1.

It does not start, does not update, or forgets what you saved? Find what you see below, and do only that step. Most units come back.

Charge the FM-1 fully first. Never unplug it during an update. And don't try one tool after another: if a step does not help, stop and write to us – most units come back.

What you seeWhat you doWhat you need
It plays, but updates fail – or it saves only to RAM (“SAVED (RAM)”, gone after power-off). A flash backup from M-Flasher shows the chip's ID B3 60 14.Stop here. No rescue tool, and don't install again and again: that can turn it into a dark unit. Newer FM-1s carry another flash chip (UC25HQ80) that many firmwares do not save or update on yet. Write to us with the name of the firmware on it – we tell you the safe way for it. Write to usNothing – a mail

No installer finds it, but the computer shows a USB drive “WL82 UBOOT1.00”.The chip's own bootloader still answers, and nothing can erase it. M-Flasher or the Unbricker (it saves the whole flash first) puts a firmware back through it. M-Flasher UnbrickerWindows, macOS or Linux

The hub's Rescue

FM-1

Puts a firmware back on an FM-1 that no installer reaches any more, through the chip's own bootloader. A Python script for Linux.

MvaveFM1Unbricker

FM-1

Unbricks an FM-1: first a full flash backup (read twice and compared), then it writes the firmware and checks every byte. Windows and Linux; macOS through the FM-1 Transporter.

M-Flasher

FM-1SMK-37

Backs up, restores and installs firmware through the chip's USB download mode, so it also works when the firmware is broken. Windows, macOS and Linux.

FM-1 Transporter

FM-1

Hardware: a Seeed XIAO RP2040 wired to the FM-1's USB lines reads and writes its whole flash, 1 MiB in about three seconds.
