What's the likelyhood that the 4b0906018DC masterj defined so well would cross-flash onto a 4b0906018CM. Or is there a better alternative? Thanks!
To answer my own question, no it does not work. I flashed it and attempted to use it in the car. Did not start. Downloaded and compared to original, it did not match. Re-flashed, and re-read and it did not matched. Flashed back to 4b0906018CM and all is normal.
