OBDSTAR G3 Failed to Upgrade to the Newest Time Solved

Problem:
When I tried to update my OBDSTAR X300 Classic G3, I encountered the error message “666: The server is maintaining, please try again later.” However, I purchased the upgrade yesterday. Could you please check if the server is under maintenance?

Solution:
The client currently does not support self-upgrade configuration or subscriptions. Please contact technical support if needed. If this problem occurs again during the upgrade process, please clear the cache, restart the KeyMaster G3, and then log in to your account again.

Q: What function is this? Is it built into X300 Classic G3?

A: Some functions require a credit limit, such as a PINCODE.
