Online (printer on Wi-Fi): when the printer shows that a new firmware version is available, follow the screen to update. Don't turn the power off; it can take 10-20 minutes.

Offline (microSD card):

1. The A1 or A1 mini must already be on 01.04.00.00 or later to update offline; if not, update online first.
2. Download the offline upgrade package for your printer from Bambu Lab's firmware page (button below). That page can list a slightly older version than the online update.
3. Eject the microSD card: Settings > SD Card > Eject.
4. Copy the package to the root of the card. Don't rename it or unzip it.
5. Put the card back and start the update from the printer: Settings > Firmware > Update Offline.
6. Don't turn the power off; wait 10-20 minutes.
