i have been trying to find this problem elsewhere but havent found any threads on it. i have an pcm with a 12579405 os and another that has a 12593058 os and I cannot get either to take the 12587603 os. I feel like am doing something wrong! Below is what i get when i try to read and then write the calibration. What am I missing? Thanks for any help!
