Some users reported that they had no problem reading Land rover KVM unencrypted and virgin ones but had issues cracking the 9S12XEQ384 chip on the encrypted ones using Xhorse Multi Prog and XDNP16 Land rover KVM solder free adapter.
Here is the customer solution:
Cleaning the 1st and 3rd leg on the Oscillator and adjusting the Pogo pins inwards usually solves the cracking issues.
If still not working, send a diagnostic report to our customer service.
