I bought a Falcon someone apparently tried to replace the DVD drive in so I need to get the key to finish what they started. The dash is 6690 with CB 5766 and this is jtagable from what I've read but the highest dash in J-runner is 7371. Sorry if this is a noob question but what do I need to do here? I've been searching for the answer but can't find it. Thanks.
