Here share the solution to resolve Launch X431 CRP909 registration failure problem.
Problem:
There is something wrong with my launch crp909 (SN: 979794xxxxxx). It cannot register successfully, and the system prompts me the serial number is incorrect. But I check the serial number I input, and it’s right. So how can I register it successfully?
Obd2tool.com engineer provides the suggestion as below:
1.Please connect WiFi on the Launch CRP909 firstly, then input your available email address to register an account;
2.Download the car software
Or click update directly to see if it pops up and asks for an account, then use your email address to register
