Before you plug in
Use a USB-C cable that carries data (not a charge-only cable).
Click Connect device & install, then pick the board from
the Chrome port picker.
Flashing from this page erases the whole device, including your
key vault. Make sure your 12-word backup is written down before
you flash — afterwards the device starts fresh (new key, or restore).
Have your 12-word backup? Restore it at
recover.flink.club once flashing
finishes, then set a new PIN on the device.
First flash on a factory board
If the board has never run this firmware, you may need to hold the
BOOT button while plugging in the USB cable (this forces the
ROM bootloader), then press reset once flashing finishes.
