Your file with checksum OK.
You modify file in 4 places, so need to correct 2 zones not one ;)

You have so big problem to post the ori file ?
Off file is well done but you need MPPS or BDM for calculate checksum in write, else only with orig with comparing is possible to realize the cks calculation.
