i know you hate hearing that you may be wrong once in a while
but your wrong.
if you clone ecu, you cannot adapt because ecu has corrupted clone which does not match the hsm or something like that because after i had cloned it, it wouldn't communicate correctly. only after i had re frf after cloning did it fix the issue. this is what happened in my experience.
The reason that happened is that you adapted immo on the wrong software before you cloned anything.
I've done this
many times using the same procedure. You've done it once and screwed everything up. Congrats.
If immo is not authenticated or you are not in bootloader, then you can't "FRF" anything, it won't enter CBOOT.
But there's no sense talking to you because you don't even have a clue what you did anymore.
The difference between me and you is, that I know how it works, you don't. But IDC, do what you like.
I'll keep using the working method I described, which doesn't involve voodoo and flashing shit 10 times instead of doing it once.
