Long story short, this is my project car, and I have been trying to add BLIS to it. I have only got the mirrors and the mirror caps off from a 2007 s60 (blis worked no issues on donor car), but not the driver and the passenger door modules.
I have unlocked/enabled BLIS on CEM but it kept throwing camera error codes for both sides (4f47 and 4f48). I have went through a lot of stuff, wiring is correct, ddm and pdm sees the modules (3 lines of serial numbers).
Then I have thought if I update the software on the driver and passenger doors that should enable blis to work properly?
I have updated PDM no issues, but when I tried to update DDM it kept bricking at the last "detecting" - "detect finished 0 of 1 ECUs alive" sequence.
It keeps throwing the same "Unit DDM is not responding. Restore software of the unit from backup." and "Unit DDM is not responding."

I have tried everything I could think of. I have disabled blis on CEM again, I have pulled the pdm fuse, I have power cycled the whole car and the DDM separately, and it still says the same thing. I would like to say that prior to me messing with the software both DDM and PDM worked without issues and had no error codes other than the BLIS ones.

Please throw me any ideas that could help.
