because winols can't reconised cks of this dump
but the ori is reconised by winols without any probleme
so if the mod file will flashed in ecu the processore will not communicate with his chip

16 posts for one check-sum?
grinovsky (http://www.digital-kaos.co.uk/forums/members/193009-grinovsky/): In most cases you need to have original file to correct checksum on one modified file.

PS: Yeah, immo-off from 1st post was good, but no checksum.
Original checksum: 45 42
Corect checksum for immo off file: FA 18

[grinovsky]

it's difference here lupu
it's not probleme of wrong cks no
the probleme is that BMW had protected his dump to be immo off
this is the probleme

[javilette]
