He reached for the deployment console.
: Firmware versions can be confusing. For instance, a user on 4PDA discussed the differences between "7.3.8" and "7.3.8_1.3" , noting how one version fixed a camera mirror issue but broke parking lines. Newer versions like "8.0.2" and "8.1.2" are also available for the 9212B.
