Problem:
Read BMW CAS4 module with Xhorse Multi Prog and XDNP12 CAS4 solder free adapter.
Pins flown in/cleaned, in the pin test passes ok, Procka Mask selected correctly, external power power plugged in – processor detects as unknown and does not want to secure.
Error chip crack failed.
Any advice?
Solution:
Double check connection, if pin test passes ok, when using solder free adapter, try to lower VPP voltage to 3.3V and VCC to 5V.
You have to manually change the values of vcc and vdd.
Or read directly without an adapter.
