CAN NOT GET RID OF CHECKSUM ERRORS OS12212156 5.3 LM7 auto 4x4

OK Guys I am lost
I still keep getting this one or more checksums could not be updated, is it my xdf or my bin? Ive tried a few and still keep getting this, I am literally one clone away from starting my truck up to see if my harness i made works.
99 pcm cloning with a 2002 (12212156) (as i was told i needed to do) using OS12212156 - 2002 xdf (Tried v1 and V4)
5.3,LM7 auto,4x4, tried every bin i could find
All i need for now is vats and emissions removed, then will need to adjust fans and other stuff later.
I have been trying this since friday and just cannot figure it out.

Thanks!

Give this XDF a try and see if the checksums work out. Make sure to copy the checksum file to your Plugins folder in your TunerPro folder.
