Problem:
I have a problem generating a new 4D 40bit chip with xhorse remote. vvdi key tool max says prepare failed. Change hotspot still nothing. Any idea how to fix it?
Solution:
You were using the wrong remote which cannot be used to generate chip.
You will need a super remote to generate this chip.
