Unless otherwise specified in the release notes of a particular version, the recommended HP Prime firmware version is 2.1.14425 (2020-01-16) (G1) and 2.1.14603 (2021-12-02) (G2).

IMPORTANT: A serious bug in the 2021-05-05, 2021-10-01 and 2021-12-02 firmware version for the G1 Prime calculators (only Hardware A devices) renders SGS Prime COGO unusable. The solution is to downgrade to version 2020-01-16 if you have already upgraded to the latest. Download the Downgrade Instructions
