Pressing SET and DISP button again results in:

- The vers.req file works, too.
- Pressing SET and DISP button a third time results in:

The number P-ID:331B is a hexadecimal code for the platform version id. Note that the platform ID is almost the same as the S3 IS model: 311B vs 311A. Platform codes for other models can be looked up under P-ID.
