- Install the updater (run as Administrator).
- Connect the N-SL via USB (do not use Bluetooth for firmware updates).
- Press L + R + Home button simultaneously for 3 seconds to enter "Update Mode" (The LED will flash rapidly).
- Open the updater – It should say "Device Connected: N-SL V2."
- Click "Update" and wait. Do not unplug the cable.
- After success (progress bar 100%), close the tool, unplug, and press the reset button (pinhole on the back) for 1 second.
