| About screen shows | What it usually means |
|---|---|
| The same version as before | The firmware was reinstalled at the same version. Support confirms which action your USB should run. |
| 74.00.331 or another newer build | ScreenTune does not support that build, and the USB shows no prompt. See unsupported firmware. Do not downgrade without a support review. |
| An older build | The CMU was reflashed to earlier firmware. See unsupported firmware. |
