Users can still use software when OBDSTAR devices upgrade expired. However, recently two customers gave feedback that OBDSTAR X300 DP PLUS prompts “The valid upgrade time of your software has expired. Do you have the upgrade life? [CORE]-101”, and they cannot use all software.

Here are the solutions:

Solution 1. Buy X300 DP Plus update service.
Update software you need and it’ll work fine.

Solution 2. Re-install software
