Most likely you are trying to burn the card with an old version of X2, which completely does not work.
You need software for 2024.
Please answer the questions:
Where did you buy the X2 and at what price?
What software is included?
Have you received unique IST files for each bin card?
How many IST files do you have in total?
What guide do you use to record dumps?
The following cards should be recorded normally:
- J2A040
- J2A040M
- JCOP21-36M
If one doesn't work, try another model.
