Hey everyone, I recently had to use a friends laptop to use rom editor but it keep cycling my friends car for CHECKING ECU, Found ECU, check ISO, CHECKING ECU over and over.

ECU IS not bricked and fans arent on.

What could be the issue?

 

Defective cable. Try a different USB cord

 

Edit:

It looks like indeed it was a defective cable, used a new usb cord from the store and its all good to go.
