I just updated my V2, and after I copy the P10_A.pmm and P10_M.pmm (BTW GM never released a manual for the P10 FWIW) I get nothing in the F1 Select Vehicle section. Tried copying the LS1B_A.pmm and still get nothing. However, I dont have my V2 connected to my TrailBlazer, dont know if Im allowed to select before Im connected or not. Im using internal memory, no SD card handy.
Oh, and the bootblock/firmware upgrade took less than a minute and was flawless on my end. Can copy files to/from easily too.
