If i make fix for bcm2 eprom it does not work for you. even with sync key file it makes the same file i gave you.

if I export elv and fix elv... its the same as the elv file you gave.

uploading your files online reveals that your BCM2 does have errors that can be fixed online but not for free

Update:

Online dump fix and car started.
