Hello all,

just wondering if anyone has access to a stock file for a 2008 LMM? The VIN # is 1gchk33608f106441. I made a dumbass mistake and didnt save the stock file when I flashed os 8594 in to the pcm. After the flash the front speakers, backup dinger no longer work? Has anyone else experienced this with a possible o.s. mismatch or ????
