### Troubleshooting 1: My nice!view doesn't display any graphics after flashing a custom firmware.&#x20;

To resolve the issue of the nice!view not displaying graphics after flashing a custom firmware, you will need to enable the `nice_view` and `nice_view_adapter` features in your custom ZMK firmware.

Example: <https://github.com/beekeeb/zmk-config-corne-chocofi-with-niceview/blob/main/build.yaml>

```yaml
include:
  - board: nice_nano_v2
    shield: corne_left nice_view_adapter nice_view
  - board: nice_nano_v2
    shield: corne_right nice_view_adapter nice_view 
```

### The firmware pre-flashed in the pre-soldered wireless keyboard

The pre-soldered wireless Chocofi or Corne 36-key keyboard with nice!view is pre-flashed with miryoku ZMK firmware. (Ref / Keymap: <https://github.com/manna-harbour/miryoku_zmk>)
