Hello,

So I have an ID5 unit on which I applied a HU work tool 3.9 BIN file few weeks ago, all was good

Now I need to change the VIN, so I VO coded the unit with the new VIN, gives me an error that's OK, in order to apply newly generated BIN with new matching VIN.

Problem is BIN don't load. Unit does not reboot. 
I just flashed the unit, it has istep 11.2017, so BIN should run. Unit was never flashed to 11.2018 istep, in case in makes a difference.

All FSC are naturally having that status now : FSCStatus rejected

So I tried to load FSC files individually, like sometimes it won't change VIN until you do so, but every single one gives me the following error:

 code: RoutineControl returned negative response

 description: service Routine Control Verify FSC returned positive response with with result status = SIG_CHECK_FAILURE; LinkName: HU_NBT2_63_ETHERNET
 severity: ERROR

So I reflashed unit for a 2nd time with new VIN too now, so both CPS and VIN are matching now
Still unable to load those FSC files and BIN don't load

I generated BIN several times, won't work for that unit, works on others.

Any idea guys what is going on?
