Step #1: Reading ROM info ..
 Searching for EPK signature...OK
 Searching for ECUID table...OK
 EPK         : '40/1/ME7.5/5/4019.00//24b/Dst02o/220900//'

my ols says 7 as well. but if you correct the file with both ols and me7sum there are no differences between the 2 corrected files.

I checksummed your checksum so you can checksum your checksum?

this is what it kicked out for me!!!

    ooo didnt know thank you !!!!
