How do you know the patch doesn't work on older firmware even if get red screen/reboot, as you said in the other post you upgraded cic to latest??? :huh:

Because before the upgrade i had C16 and it didn't work, but the screen went red and rebooted. I checked FTP and rcert.swt was not uploaded by the script, it was the old one, and patching the binary didn't work. Also for some reason i couldn't see HmiMain binary or CicEceUsaHighSecond in /usr/HBproject (for size/date comparison to see if the script actually worked). Don't know if it was an OS thing (hidden files or something) but i didn't dig further.

I also kind of "decompiled" 20% of the patcher with IDA Pro just out of curiosity and it does have a check function for the SW version (couldn't not see where it checks).

As soon as i upgraded to C1A (sp daten v60, i guess it's the same version on v59, mine is E-series) everything worked smoothly with the same FSTOOL setup i had. Even 9C FSC uploaded successfully.

For maps code generation, you don't need to fetch the 1B from CIC, just use the signed one you used to upload in the CIC. My problem was the FSC generator, it didn't accept a "virgin" 1B FSC of 151 bytes. Probably it would have expected the 319 bytes one which is usually used. But i switched the generator and use the code for my map (in this case Middle East Premium which is 0x36) and 0xff for lifetime activation and it worked.

Once again, thanks intel123 for your inventive work and the willing to help a big community of BMW users
