it's not encrypted it's other format dwn
this format is used by special software to update the ecu
but if converted to binary you can use it
the dwn format is used by provider

open file with hex editor and you will see.
maybe some sync blocks are inside etc but if I use bytes after this offset ols is detecting it as edc16c39 with wrong checksum. original for compare would be helpful.

but the original have a mistake and this update is for correct it
this file is used by scan100 interface to update chevrolet ecu by obd

sorry my freind but you are wrong
there is no one manufacturer in the world that use bdm to update ecu
they all update the ecu by obd but not with binary fille and this is the right way to program by obd
this dump was created in database of software diag for daewoo and chevrolet when i installed it in order to update the ecu from obd
you can read again the pdf
